Astronomy’s Limitless Journey

by Brea Aamoth

‘Imiloa presents Dr. Günther Hasinger, Director of the Institute for Astronomy

Date: Fri. July 21
Time: 7:00 p.m.
Cost: $10, $8 for members (member level discounts apply)

When observing the sky on a very clear, dark night, one can see the soft glow of the Milky Way and its thousands of stars with the naked eye. Over the centuries since Galileo first pointed a telescope at the galaxy in 1609, this awe-inspiring yet easily visible panorama constituted our cosmos, our entire celestial world. With each new scientific discovery, however, this cosmos has grown dramatically, expanding rapidly over the last several decades. As we look deeper into space, the earlier phases of the cosmos are unveiled to us, but we know that even with the largest telescopes, we see only a tiny fraction of the vast expanse of the universe. Learn more about this quest to understand our universe at ‘Imiloa’s next Maunakea Skies talk with Dr. Günther Hasinger, Director of the Institute for Astronomy and author of Astronomy’s Limitless Journey, on Friday, July 21 at 7:00 p.m.

In Astronomy’s Limitless Journey, Dr. Hasinger takes the reader on an exciting time travel journey to the far reaches of the universe, beginning with the incredibly hot fireball of the Big Bang roughly 13.8 billion years ago, and the suspected ending in distant eons with a cold, dark demise. In between is the period during which extensive structures, galaxies, stars and planets were formed.

.

Astrophysics and cosmology are experiencing a “golden age” due to larger telescopes, faster computers and more sophisticated algorithms. These fundamental changes are taking place in our understanding of space and time and of the origin and future of our universe. Dr. Hasinger details this evolution and describes the methods utilized in modern astrophysics, while cautioning that the boundaries between knowledge and ignorance are constantly shifting. Every new discovery opens a further door to the unknown, and with every answered question, we discover more locked doors yet to be opened.

.

Dr. Hasinger is a world leader in the field of X-ray astronomy and in the study of black holes. He received both his physics diploma and his PhD in Astronomy from Ludwig Maximillian University (LMU) of Munich, Germany. He served as the Director of the Astrophysical Institute Potsdam from 1994 to 2001. In 2001 he was appointed as the Director of the High-Energy-Group at Max Planck Society (MPE), one of the world’s premier research organizations. In 2008 he became the Director of the University of Hawai‘i Institute for Astronomy. University of Hawai‘i Press published Astronomy’s Limitless Journey in October 2015.

How to “Photograph” a Black Hole

by Emily Peavy

Reflection on Maunakea Skies: A Telescope the Size of the Earth with  Dr. Alison Peck, representing Very Long Baseline Array (VLBA)

Black holes are the enigmatic, mysterious objects that populate our sci-fi movies and excite our imaginations. Scientifically, black holes are objects that are so dense that gravity has collapsed them into a singularity and light can no longer escape the object’s gravity. Black holes are typically found by looking for their effects on nearby objects. This is how astronomers discovered the supermassive black hole in the center of the Milky Way galaxy, named Sgr A*.

This data observes stars that orbit Sgr A*. Made from images taken over 10 years with 8.2-m VLT YEPUN telescope at the Paranal Observatory, operated by the European Southern Observatory (ESO) in Chile and published in the scientific journal, Nature.

 

Now that black holes have been discovered, scientists want to know, is there a way to detect them directly? Astronomers utilize a technique known as Very Long Baseline Interferometry (VLBI)  which simulates large telescopes by linking smaller arrays of radio telescopes together. This process increases the angular resolution that can be obtained. The resolution required to observe the event horizon of Sgr A* has the equivalence of attempting to observe a grapefruit on the moon from Earth. Thus the Event Horizon Telescope links arrays from around the world to create ‘a telescope the size of the Earth.’ This scale of VLBI has never been done before and will create a new precedence of resolution that can be obtained with this method.  

 

What can we expect to see?
Astronomers have already used the Event Horizon project to capture more data from Sgr A* hopefully getting a peek at its event horizon. As we wait for this data to be processed and analyzed, we can simulate what we might find based on different scenarios. Below we have simulation models testing different circumstances.

“Remember, it takes scientists a long time to interpret the data and understand what’s really going on,” Dr. Peck concluded. “So we have to be patient, let them analyze the data, discuss it with all of these groups, and then hopefully they will show us the real data and some art that will help us understand what it really means.”

This simulation compares what we can expect based on how many telescopes participate. The images on the left are 2 models while the center sees the models with 7 telescopes, and the right sees the models with 13 telescopes. Currently the Event Horizon Telescope utilizes 8 telescopes.

The Search for the Origin of Gold

by Brea Aamoth

‘Imiloa presents Dr. Michitoshi Yoshida, Director of Subaru Telescope

Date: Fri. June  16
Time: 7:00 p.m.
Cost: $10, $8 for members (member level discounts apply)
Gold is one of the most coveted and valuable natural materials in the world, but where does it come from and how was it originally formed? It may be a surprise, but scientists are still searching for the definite answer to this question. Learn more about this valued stone and the science behind it at ‘Imiloa’s next Maunakea Skies talk titled The Search for the Origin of Gold on Friday, June 16 at 7:00 p.m. with Dr. Michitoshi Yoshida, Director of Subaru Telescope.

.

Scientists have discovered how most natural materials on Earth were originally created. The majority of lighter chemical elements in the universe were synthesized by fusion reactions inside of stars. Heavier elements such as silver, mercury and titanium are formed by a “neutron capture” reaction. This reaction has two processes: slow capture process (s-process), which can form mercury, titanium and lead atoms; and rapid capture process (r-process) which forms atoms of gold and platinum. The site of s-process is well known as the central regions of dying stars. However the site of the r-process, the creation of gold, has not yet been identified. In other words, we don’t know the birthplace of gold, and scientists are on the hunt to discover it.

.

One candidate for the creation of gold is in the process of merging neutron stars, which are extremely dense remnants of massive stars. When two neutron stars merge, a giant explosion occurs and the neutron-rich environment in the explosion would drive the r-process to synthesize gold. Such an event has yet to be observed, so the search for the creation of gold continues. Using state of the art gravitational wave detectors, many astronomers and physicists are now searching for the birthplace of gold by implementing multi-wavelength electromagnetic observations of these gravitational waves. Dr. Yoshida will introduce these trials, including some attempts made with the Subaru Telescope that resides on Maunakea.

.
Dr. Yoshida was born and raised in Kyoto, Japan. He received his PhD from Kyoto University, and his career as a professional astronomer began at Okayama Astrophysical Observatory (OAO), which is a branch of National Astronomical Observatory of Japan (NAOJ). In 1995 he came to Hilo in support of the initial construction of the Subaru Telescope, also a branch of NAOJ. After the construction he returned back to OAO and became its Director. He was also named Director of the Hiroshima University from 2010 to 2017 until recently being appointed Director of Subaru Telescope this April 2017. Dr. Yoshida’s main research field is optical-infrared observational astronomy of galaxies and high-energy transient objects. He has recently gained interest in gravitational waves and its relation to astronomical phenomena.

Reflection: Ground Breaking Technology to Answer Age Old Questions

by Emily Peavy

‘Imiloa invited Dr. Luca Rizzi, Support Astronomer from W. M. Keck Observatory, to the planetarium for our monthly lecture series Maunakea Skies. In his presentation titled ‘Ancient Mysteries and Cutting Edge Technology he talked about the recently installed Keck Cosmic Web Imager, which is a research instrument that allows scientists to look at the faintest most diffuse structures of the universe. Dr. Rizzi explained how this advanced instrument pushes new technological developments and will soon answer some of the greatest mysteries of the universe.

Ground Breaking Technology to Answer Age Old Questions

For the past 6 years Astronomers and Engineers from Keck Observatory have worked with a team at Caltech, University of California Santa Cruz, and industrial partners to design and build a revolutionary instrumentthe Keck Cosmic Web Imager. This state-of-the-art spectrograph is able to capture 3 dimensional spectral signatures with unprecedented detail allowing astronomers to study the filaments that connect galaxies across the grand scale of the cosmos. The finished spectrograph arrived in Hilo on January 20, 2017, and was installed as an instrument on the Keck telescope. The instrument made its first observation, a test spectral image of a nearby Globular Cluster, M3 on April 11, 2017 at 2:30 a.m.

Far-Sighted Philanthropy: The Minnesota Connection

by Margaret Shiba

So far this spring more than 500 Big Island schoolchildren have benefited from free field trip transportation to ‘Imiloa, thanks to generous philanthropy from an unusual source—a small group of alumni from Carleton College in Minnesota!

 

A typical day at ‘Imiloa sees a wide variety of visitors coming through the door…businesspeople meeting over breakfast at Sky Garden, tour groups stopping en route to Volcano National Park, K-12 students piling off schoolbuses for field trips, community members checking in for an event in Moanahōkū Hall. December 2, 2016 began as one such ordinary day, but by the time it was over, an inspiration had struck and within a month, a total of $5,900 had been raised to support 2017 field trips to ‘Imiloa by Big Island schools.

 

This impromptu fundraising campaign was made possible by 24 members of a Carleton College Alumni Study Tour who visited ‘Imiloa as part of a customized 8-day program on Maui and the Big Island, “Hawai‘i World-Class Observatories & Natural Wonders.” When severe winter weather forced the cancellation of the group’s planned site visits to telescopes on both Haleakala and Maunakea, the group’s stop at ‘Imiloa took on added significance, introducing the visitors to the impressive history and accomplishments of astronomy in Hawai‘i, along with the parallel story of early Polynesians who navigated their way across the Pacific using the light of the same stars.

 

As it happened, the Carlton alumni happened to be touring the ‘Imiloa Exhibit Hall at the exact same time as a group of 134 energetic fourth graders from Kea‘au Elementary School. The children’s obvious excitement over the astronomy and navigation content won the hearts of the mainland visitors, and when they learned about ‘Imiloa’s “Adopt a Visit” fundraising program, two of the participants, Ester Gubbrud and Charlie Ross, generously offered to match donations from everyone in the group. As Ester later commented, “We suggested the group donation as a ‘crazy idea,’ and everyone immediately jumped on board. It just grew really quickly. Between matching donations and our corporate employee gift matching programs, every $1 donated turned into $4 for ‘Imiloa!”

Another Carlton alumna, Deborah Gavrin Frangquist, commented how much she appreciated having an opportunity to walk alongside the model of the Hōkūalaka‘i voyaging canoe and get a sense of life on board, “but what truly delighted me,” she said,” was the presence of the children busily exploring, investigating, calling each other’s attention to what they were learning. At one point, a small group of students rushed to an exhibit near where I was standing, and a chaperone apologized for their possibly blocking my view. I told her that I enjoyed seeing their enthusiasm and that the center really exists for them. She said, “But you paid to get in,” and I replied, ‘On their behalf.’ It’s truly an honor to join with other Carls in making it possible for more students to visit and learn at ‘Imiloa.”

 

Dr. Joel Weisberg, Carleton College Professor of Physics and Astronomy and one of the tour’s two academic leaders, stated that Gubbrud and Ross’s effort is emblematic of the caring nature of Carleton alumni and students that has inspired him through his thirty years of teaching there. “They mobilized the whole tour group to provide financial resources to facilitate ‘Imiloa’s important mission of furthering understanding of both astronomy and Hawaiian culture.

The other Carleton tour leader, Dr. Sidney Wolff, is an astronomer who was with the UH Mānoa Institute for Astronomy for 17 years and served as the first director of the international Gemini Observatory project during its early years. She points out that “Many scientists first became interested in science as children through fascination with astronomy and space science. I hope that some of the children who visit ‘Imiloa because of our donation will be similarly inspired to pursue careers in science.”

 

Carleton College is an undergraduate liberal arts college in Northfield, Minnesota with a distinguished record of national leadership in science education. More than a third of its students major in math or science, and about 20 percent of its graduates go on to work in scientific research or healthcare.

 

“Mahalo nui loa to our new friends from Carleton,” says ‘Imiloa Executive Director Ka‘iu Kimura. “‘Imiloa owes our founding to a unique set of geographical and historical circumstances, but we see universal applicability in our mission to explore science and culture as different facets of the same reality. Even on a short visit from far away, the Carleton alumni immediately understood and embraced this mission…and then stepped up with financial support to help ‘Imiloa inspire the next generation of innovators and explorers. It is a privilege to have worked with them on this special project and we salute their far-sighted philanthropy!”

Each year ‘Imiloa opens our doors to 10,000+ K-12 schoolchildren for curriculum-related field trips, and we are grateful for the support from private donors which makes it possible for us to offset the cost of many of their visits. To donate online, visit: www.uhfoundation.org/SupportImiloaFieldTrips or contact Margaret Shiba, Director of Institutional Advancement at 808.932.8921 or mshiba@imiloahawaii.org.

‘Imiloa presents Dr. Alison Peck, representing the Very Long Baseline Array (VLBA)

Date: Fri. May 19
Time: 7:00 p.m.
Cost: $10, $8 for members (member level discounts apply)

We’ve all seen black holes popping up in science fiction movies and even in some ‘end of the world’ theories, but do black holes really exist and, if so, can we find them? The answer is yes—with the help of telescopes from around the world, including observatories on Maunakea. Learn more about black holes and how we can spot them by linking telescopes across the globe to create ‘A Telescope the Size of the Earth,’ at ‘Imiloa’s next Maunakea Skies talk on Friday, May 19 at 7:00 p.m. with Dr. Alison Peck, representing the Very Long Baseline Array (VLBA) on Maunakea.

In April 2017, astronomers worked together to combine advanced technology in an extraordinary technique called Very Long Baseline Interferometry (VLBI) linking ground based instruments around the world to create, in effect, one giant telescope called the Event Horizon Telescope (EHT). The EHT will deeply explore and target the supermassive black hole that resides at the center of our own Milky Way galaxy. The goal of this ambitious collaboration is to capture the first image of a black hole’s event horizon, which is the point where light can no longer escape the object’s gravity. Dr. Peck will discuss the circumstances that cause black holes to form, and some of the methods that astronomers use to detect these exotic objects in space. As more data is collected through the EHT, the more scientists are joining in this global development in the quest to grasp a deeper knowledge of black holes, the mysterious objects that challenge our laws of physics.

An Artists’ interpretation of a black hole

Dr. Peck, who currently serves as a Scientist at Gemini Observatory, has an extensive history of undertaking complicated projects in radio astronomy.  She has been using the VLBA since she started working on her PhD in Physics at New Mexico Tech in 1994. After obtaining her PhD she spent two years in Germany where her focus was searching for gas falling into giant black holes.  She moved to the Big Island in 2001 to work at the Smithsonian Submillimeter Array, and then went on to Chile in 2007 to commission the Atacama Large Millimeter/submillimeter telescope, the largest ground-based telescope project in the world. She continues utilizing the VLBA and other international Very Long Baseline Interferometry facilities today, including several of the telescopes that took part in the recent observations of the Galactic center. Although she has studied and worked all over the world, Dr. Peck says she is always happiest when she is working on Maunakea.

Reflection: Learning to Live on Mars, on Mauna Loa

by Emily Peavy

‘Imiloa invited Brian Shiro, Geology Lead for the Hawai’i Exploration Analog and Simulation (HI-SEAS) program, into the planetarium for the monthly lecture series Maunakea Skies. He discussed the ongoing project where NASA researches issues relating to long-duration missions to Mars, on Mauna Loa in Maunakea Skies: Learning to Live on Mars… on Mauna Loa.

Simulating Mars
Throughout recent years NASA has gained a new interest in sending humans to live on the planet Mars. Such an expedition to the Red Planet introduces an array of challenges that need to be addressed before a full mission could be planned. Some of these challenges relate to the great distance from the Earth which would mean that potential astronauts would have to deal with long mission duration, isolation, and time delays in communication with Earth, all of which can affect overall psychological health. To study and address issues relating to these challenges NASA has created and utilized an analog site on the slopes of Mauna Loa; this is the HI-SEAS project.

The HI-SEAS site is a disused quarry site on the slope of Mauna Loa. This ideal environment simulates Mars in that its isolated, the basalt is similar to that we find on Mars, and it visually looks like the Red Planet. The habitat is a temporary structure that uses solar panels and hydrogen fuel cells for power. While the research purpose of the project is to test the psychological effect of isolation, a tangential effort is being made to develop sustainable building practices, low resource use, and “smart” sensors which regulate the habitat’s internal environment.

Living and Working in Isolation
Since its conception in 2012, HI-SEAS has conducted 4 missions with its 5th mission currently in progress. These missions last from 4 months to 12 months. Crew members live in the habitat throughout this time and can only leave the habitat during Extra Vehicular Activities (EVA’s), which occur only a couple times each week, and the crewmembers must wear space suits like the ones that would be worn on Mars. Crew members are given projects such as mapping geological features of the area and running geological tests. The results of these projects are compared to tests conducted by geologists unhindered by the suits and long term isolation to see how the unique environment affected the crew members.

Learn more about this exciting projects by visiting UHH News, West Hawaii Today, New York Times, The Daily 360 Video, Time and at the HI-SEAS website. Tours of the habitat site are available between missions. If your organization might be interested in a tour contact Dr. Kim Binstead at binsted@hawaii.edu or Dr. Bryan Caldwell at bryan@xclassmanagement.com.

‘Imiloa’s Merrie Monarch Cultural Enrichment Programs

by Imiloa Astronomy Center

In celebration of the 54th Annual Merrie Monarch Festival, ‘Imiloa Astronomy Center will host three days of cultural enrichment programming, Wednesday, April 19 through Friday, April 21. This series is organized annually at ‘Imiloa to complement and honor Merrie Monarch’s major purpose: the perpetuation, preservation and promotion of the art of hula and Hawaiian culture through education.

.

Join us at ‘Imiloa and immerse yourself in the beautiful stories delivered through the art of hula and chant by Hālau o Kekuhi. Serenade your senses with live music by Grammy® Award Winner Kalani Pe‘a. Discover the traditions of oral stories in the Oli Workshop by Kumu Hula Mehanaokalā Hind, and much more!

.

The opening day of events at ‘Imiloa (Wednesday, April 19) will showcase the Oli Workshop with Kumu Hula Mehanaokalā Hind at 10:00 a.m. Hind will share mele aloha ‘āina that showcase Hawaiian perspectives of origin and connection to the land. Hind is a Kumu Hula and cultural practitioner skilled in hula and oli. She descends from the hula lineage of Kumu Hula Leinaʻala Kalama Heine and has been trained in mele oli by some of Hawaiʻi’s master chanters.

.

The afternoon session will feature a film screening of Nā Hulu Lehua: The Royal Cloak and Helmet of Kalaniʻōpuʻu. This documentary film shares the historic story of Kalaniʻōpuʻu, aliʻi nui (high chief) of Hawaiʻi Island, who greeted Captain James Cook in 1779 at Kealakekua Bay and draped his treasured ‘ahu ‘ula (feathered cloak) over the newcomer’s shoulders as a gesture of goodwill. While Cook himself would never leave Hawai‘i, Kalaniʻōpuʻu’s feathered cape and mahiole (feathered helmet) sailed back to Europe with Cook’s crew, and ultimately ended up at the National Museum of New Zealand Te Papa Tongarewa. Over 230 years later, the Office of Hawaiian Affairs, Bishop Museum, Te Papa, and Hawaiian Airlines collaborated in an unprecedented partnership that enabled the return of Kalaniʻōpuʻu’s priceless garments to Hawaiʻi. Hind, who participated in the returning of Kalaniōpuʻu’s cape, will lead the screening with a Q & A to follow. This afternoon session will take place at 1:00 p.m. on Wednesday, April 19.

.

A live musical performance by Hilo’s own Lito Arkangel will kick off on Thursday, April 20 at 10:00 a.m. Arkangel has a personal connection to the songs he presents, and delivers more than words, but an essence of the story captured in mele (song). He spent most of his youth growing up in Keaukaha with ‘ohana who have guided him through the many facets of Hawaiian culture and upbringing. Lito perpetuates Hawaiian music and culture as a teacher, mentor and professional musician. Join Lito as he shares mele from his two albums, Me ke aloha (2014) and Kuʻupau (2017), along with the special stories that connect him to these mele Hawaiʻi.

.

Enjoy an afternoon hula and costume presentation by Hālau o Kekuhi. Across various dancers and dance instructors, it is a common understanding that costuming should reflect either the performer, the story within their dance, or both. Join Hālau o Kekuhi as they perform hula and lead a conversation that explores the dancer’s kuleana (responsibility) to create a unique environment through detailed chant, motions and intentional costuming. This performance will take place on Thursday, April 20 at 1:00 p.m.

.

Kealopiko will open the morning session on Friday, April 21 at 10:00 a.m. with He leo aloha: a presentation on the language and story in the Kealopiko design process. The idea to start Kealopiko grew out of a deep aloha for the islands, the history, its people and the Hawaiian language. “Figuring out how we articulate the many voices of the past and present in story and design forms the core of what we do and is an ever-changing process that continually educates us as founders,” says co-founders Jamie Makasobe and Hina Kneubuhl. “As we grow, so does our process and the language we find and use to reconnect elements of the natural and cultural landscapes to our modern day existence.”

 

Culminating ‘Imiloa’s Merrie Monarch programming is a live musical performance by 2017 Grammy® Award Winner, Singer/Songwriter Kalani Pe‘a. His debut album E Walea features seven haku mele (Hawaiian original music compositions) and five of his favorite covers. E Walea hit number 1 on the iTunes world music charts, and in August of 2016 it hit number 12 on the Billboard world albums charts. In February of 2017 the debut album took home the Grammy® Award for Best Regional Roots Music Album. Pe‘a is a native to Panaʻewa, Hilo and currently resides on Maui. Join Kalani Pe‘a as he presents mele from his award-winning album and shares his passion for perpetuating the Hawaiian language through music and visual arts. Pe‘a’s performance will begin at 1:00 p.m. on Friday, April 21.

.

Reflection: Near Earth Object (NEO) Hazard, NASA’s Planetary Defense

by Emily Peavy

‘Imiloa invited Rob Landis, Engineer with NASA’s Planetary Science Division, and Dr. Kelly Fast, Program Manager of the Near-Earth Object Observations program in NASA’s Planetary Defense Coordination Office, to the planetarium where they discussed the rocks that have been nudged near Earth’s orbit in their presentation Near-Earth Object (NEO) Hazard: NASA and Planetary Defense.

Raw Ingredients of the Solar System

The presenters described the planets in our solar system as ‘finished’ or ‘well-baked’ as they have collected enough mass to create a round shape and main a cleared stable orbit. If we consider planets in our own solar system as ‘well-baked’ then the asteroids circling planet Earth are the ‘raw’ ingredients which are left over from the formation of our solar system.

Since 1801, we’ve discovered millions of asteroids which are scattered throughout the solar system. Most asteroids orbit between the regions of Mars and Jupiter, in the Main Asteroid Belt. A Near-Earth Object, or NEO, would be any object whose closest approach to the sun is less than 1.3 astronomical units (AU) or 194 million kilometers (km) away (the Earth is 1 AU or 149 million km from the sun on average). While these objects are designated as “Near-Earth,” most of them never come too close to the Earth as they orbit –however NASA’s newly established office, the Planetary Defense Coordination Office (PDCO), is set in place to detect, track and characterize these potential asteroid hazards that are “Near Earth” in order to protect us.

 

Scientists also consider a sub-set of NEOs which have been designated as Potentially Hazardous Objects, or PHO; these objects will intersect with Earth’s orbit less than 7.5 million km away from our planet.

 

Search and Detect Program

NASA coordinates with observatories from around the world, one of which includes the University of Hawai‘i’s own Pan-STARRS on Haleakalā, Maui. The Minor Planet Center operates as an international observation database and works to determine the orbit of objects in our solar system. While the Center for NEO Studies, with the Jet Propulsion Laboratory, conducts precision orbit determination and assesses the impact risk with an automated Sentry. When a new NEO or PHO is detected— observatories, including NASA’s Infrared Telescope Facility on Maunakea, will conduct follow up observations to further expand our knowledge of these objects. As of March 4, 2017 15,742 Near-Earth Objects have been detected with 1,788 of them being Potentially Hazardous Objects.

Cutting Edge Technology and Ancient Mysteries

by Brea Aamoth

‘Imiloa presents Dr. Luca Rizzi, Support Astronomer at W.M. Keck Observatory

Date: Fri. April 21
Time: 7:00 p.m.
Cost: $10, $8 for members (member level discounts apply)

Continuing the tradition of keeping Maunakea at the forefront of astronomical research, the W.M. Keck Observatory recently installed a new research instrument called the Keck Cosmic Web Imager. With unparalleled capabilities and extreme sensitivity, this instrument will allow scientists to look at the faintest and most diffuse structures of the Universe, and investigate the pillars of dark matter that caused the formation of the primordial galaxies and galaxy clusters. Learn more about this quest for astronomical knowledge at ‘Imiloa’s Maunakea Skies talk with Dr. Luca Rizzi, Support Astronomer at W.M. Keck Observatory on Friday, April 21 at 7:00 pm.

The Keck Cosmic Web Imager will be one of the best in the world for capturing images of cosmic objects in great detail. These unique capabilities will allow astronomers to view detailed images where each pixel can be viewed in all wavelengths of visible light. Dr. Rizzi will share the mesmerizing questions that this instrument will be able to answer, which will soon open a new wealth of knowledge in the astronomy community. He will also touch on the adventurous construction and challenging transportation of the instrument, starting its journey in Southern California, traveling across the ocean and then eventually its trip up to the summit of Maunakea on Hawai‘i Island.

Dr. Luca Rizzi, Support Astronomer at W.M. Keck Observatory

Dr. Rizzi received his PhD from Padua University, Italy— the same University where Galileo Galilei was a teacher in the late 1500’s. Inspired by this heritage, Dr. Rizzi pursued a career in observational astronomy, first as a Post-doctoral student at the University of Hawai‘i, then as a support astronomer at the United Kingdom Infrared Telescope. Eventually his passion for astronomical observatories led him to the W.M. Keck Observatory, the largest and most scientifically productive ground-based telescope in the world. Dr. Rizzi’s duties at Keck involve overseeing astronomical instrumentation and, in collaboration with others, overseeing the flow of data for observers. He was involved in producing some of the software for this unique new instrument and was in charge of its commissioning at the telescope.
