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.

‘Imiloa Announces First-Ever Endowment Gift

by Imiloa Astronomy Center

The legacy of the late educator and government planner Ilima Pi‘ianai‘a is being celebrated through the establishment of a new endowment at the ‘Imiloa Astronomy Center in Hilo.

.

Gordon Pi‘ianai‘a of Honolulu and Norman Pi‘ianai‘a of Kamuela have made a gift through the University of Hawai‘i Foundation to create a new permanently endowed fund to honor their sister and expand access to educational programming at ‘Imiloa by K-12 students.

.

In announcing the gift, ‘Imiloa Executive Director Ka‘iu Kimura stated, “Just as we are marking the 11th anniversary of our opening, ‘Imiloa is thrilled to have our very first permanent endowment, a fund that will benefit the center in perpetuity and enable us to share our unique brand of programming with both current and future generations of young people. We are humbled by the Pi‘ianai‘a family’s vote of confidence in ‘Imiloa and excited about what this will mean in our second decade and beyond!” UH Hilo Chancellor Donald Straney added, “This wonderful gift will benefit the children of Hawai‘i for years to come.”

.

Born and raised on O‘ahu, Ilima Pi‘ianai‘a (1947-2006) pursued a noteworthy career in the public sector, starting with her service as a Hawai‘i County planner helping to develop a general plan for the island. She later served with the Hawai‘i Community Development Authority and worked on the Kaka‘ako Improvement District, among other projects. She lectured in geography and planning at UH Mānoa from 1980 to 1984, administered the Task Force on the Hawaiian Homes Commission from 1982-1983, then held appointments as Hawai‘i County deputy planning director, director of the Department of Hawaiian Home Lands, director of the Office of International Relations and Affairs, and deputy director of the state Department of Agriculture.

.

Norman Pi‘ianai‘a commented about his sister, “Even though Ilima was from Honolulu, she loved the Big Island and its people.  She moved here around 1970 and mentored in the Planning Department under Director Raymond Suefuji during the days of Mayor Shunichi Kimura, a time when things were in a process of great change in Hawai‘i.  With ancestral roots firmly planted here, we are confident that Ilima would be pleased to know she has in this way returned and will continue to help nurture and contribute to the future education and development of Hawai‘i Island youngsters.”

.

A longtime friend of Ilima, Deanne Lemle Bosnak, remembers her as “a perfect embodiment of ‘aloha.’” She personally represented Hawai‘i’s beautiful blend of cultures, its warm hospitality and its welcoming aloha spirit. She was also a diplomat who worked hard to build bridges between disparate communities and cultures, demonstrating in everything she did a deep respect for the land and the values of its people.”

.

Annual distributions from the Ilima Pi‘ianai‘a Endowment will support access to ‘Imiloa by local elementary, middle and high school students, and may include subsidized admission and or transportation to the center, subsidized fees for ‘Imiloa programs, and/or program outreach to rural parts of Hawai‘i Island and the state.

Reflection: Why is it Dark at Night?

by Emily Peavy

‘Imiloa invited Dr. Tom Geballe, Astronomer at Gemini Observatory, to the planetarium where he discussed the phenomenon of the dark night sky in Why is it Dark at Night? A Modern Look at Olbers’ Paradox.

 

Darkness Between the Stars

The first astronomical observation that every child makes is that the sky is dark at night. While we do see the pinpoint light of stars peeking through the void, as a whole the sky is dark. As we grow older, we learn that the stars that make up the nighttime sky are but a small fraction of the billions of stars that stretch across the universe. However, if there are so many stars across the whole universe, why isn’t our night sky shining bright with their combined brilliance?

Old Ideas of Cosmology

Before the advancement of Einsteinian physics and Hubble’s observations of the expanding universe—astronomers and philosophers had the natural assumption that the universe was static. A static universe means neither contracting nor expanding, with no beginning, a universe that has always existed, with an infinite number of stars shining perpetually. With this theory, no matter how far away a star is from Earth, its light would have time to reach Earth and every line of sight would end with a star.

However, today we have a different model of the universe. We know that the universe does not contain an infinite number of stars, just about 10 billion trillion stars. We also know that the universe is expanding out in all directions, and has been since its creation from the Big Bang 13.7 billion years ago. The nighttime sky is dark due to the universe’s immense present size and these properties.

Reflection: Exploring Mars with 150,000 Earthlings

by Emily Peavy

‘Imiloa invited Dr. Meg Schwamb, Assistant Scientist at Gemini Observatory, to the planetarium where she discussed citizen science projects that are currently studying unique surface features on the red planet of Mars in Maunakea Skies: Exploring Mars with 150,000 Earthlings.

Like nothing we’ve seen on Earth:
Mars is often referred to as “Earth’s little brother,” as it shares many similarities to planet Earth. Like Earth, Mars orbits within the habitable zone, its axial tilt causes seasons for the northern and southern hemispheres and it’s within the sun’s region where it’s warm enough for liquid water to exist. Despite these similarities, observations from orbiting spacecraft have revealed features around the poles of Mars that are nothing like we’ve observed from Earth.

Dark “fans” have been observed on Mars, particularly near the southern pole of the planet. These dark features are thought to be geysers of carbon dioxide (CO2). During the Martian winter, CO2 ice (also known as dry ice) collects beneath the surface near the poles. When the spring season starts warming the southern hemisphere, the CO2 ice sublimates (transforms directly from a solid form to a gaseous form) and erupts from the surface. When the Martian winds blow this material, planetary scientists are able to probe the atmosphere of the red planet and study wind patterns and other atmospheric phenomena. Additionally, some of this gas remains trapped beneath the surface and forms “spider” channels as it travels beneath the surface of the planet.

.
Many observations of these features and phenomena come from the High Resolution Imaging Science Experiment (HiRISE) instrument on the Mars Reconnaissance Orbiter, which started its orbital mission in 2006. HiRISE is able to detect surface features as small as coffee tables from the orbit of Mars.

Average, everyday people explore surface features on Mars:

Over the past decade scientists around the world have seen the rise of “citizen science” projects. These projects connect people through the Internet, allowing average, everyday people to participate in scientific projects. Planet Four and Planet Four: Terrains allows volunteers to explore and identify features, such as fans and spiders, on the surface of Mars.

Participants map out features and sort through images taken with Reconnaissance’s HiRISE camera, and the lower resolution CTX camera. Computers are not good at identifying these features, but they are easily spotted with the human eye, making these “citizen scientists” all the more valuable.

The above image shows how “citizen scientists” have mapped the observed features on Mars, and how scientists can average this information into usable data.

.
Information generated by these projects are implemented by scientists to map the poles of the red planet. This also assists in gaining a better understanding of how seasonal changes affect the surface features and the atmosphere on Mars. In her presentation, Dr. Schwamb showcased some recent discoveries from Planet Four: Terrains, including HiRISE images from some of the 20 new regions of interest suspected of having spider channels, confirmed by HiRISE imaging.

Learning to Live on Mars…on Mauna Loa

by Brea Aamoth

Tucked away on the northern flank of Mauna Loa overlooking Maunakea is a white domed structure, where NASA is studying what it takes to live on Mars. This is the Hawai‘i Space Exploration Analog and Simulation (HI-SEAS) program, which is aimed at researching issues related to how crews will function on long-duration missions to Mars. HI-SEAS creates missions and recruits crewmembers who live in the Mars-like habitat for periods ranging from four to twelve months, in order to better understand the planet’s living conditions. Learn more about this quest to make human life possible on the Red Planet at ‘Imiloa’s Maunakea Skies talk with Brian Shiro, Geology Lead at HI-SEAS on Friday, March 17 at 7:00pm.

Lucie uses the NASA KSC Swamp Works geotechnical tool while Annie records the data.

During HI-SEAS missions, some of the crew’s activities require them to leave the habitat and conduct Extra-Vehicular Activities (EVAs) while wearing simulated space suits to approximate the encumbrances astronauts would face while exploring the surface of Mars. This helps to identify and test best practices for future field explorations on the surface of Mars. Funded by NASA, these missions also include supervision by a remote support team via an imposed 40-minute round trip communications delay, replicating real-life Mars-like communication conditions. Shiro will take you through the day-to-day life of a HI-SEAS mission and what it’s like learning to live on Mars!

 

As a collaborator on this project since 2012, Shiro leads the development, assignment and evaluation of geological field tasks given to the HI-SEAS crews to gauge their team performance under realistic mission constraints. He has experience in over a dozen field expeditions from the Arctic to the Antarctic and many tropical destinations in-between. He spent over 60 days aboard research vessels mapping the seafloor and served on two simulated Mars mission crews in Canada and Utah. He received his B.A. in Integrated Science, Geology and Physics from Northwestern University, an M.A. in Earth and Planetary Sciences from Washington University and an M.S. in Space Studies from the University of North Dakota. He is currently a Ph.D. candidate at the University of Hawai‘i at Mānoa, where he applies geophysical exploration techniques to study lava tubes, seamounts and subsurface resources that could support life on other planets.

Hosted by Planetarium Technician Emily Peavy,‘Imiloa’s monthly Maunakea Skies program includes observational highlights of the current night sky over Hawai‘i, with the audience able to view prominent constellations and stars visible during this time of year.

The NEO Hazard: NASA and Planetary Defense

by Imiloa Astronomy Center

A Presentation by Rob Landis and Dr. Kelly Fast

Date: Sat. March 11
Time: 7:00 p.m.
Cost: $10, $8 for members

Near-Earth Objects or ‘NEOs’ are leftover bits of solar system jetsam and flotsam that have been nudged into orbit around the Earth, allowing them to come within our close vicinity. NASA recently established a new office to coordinate planetary defense-related activities to mitigate the hazard of potential impact by such asteroids. Learn more about possible asteroid impacts, and NASA protection efforts at ‘Imiloa Astronomy Center’s upcoming astronomy talk with Rob Landis and Dr. Kelly Fast on Saturday, March 11 at 7:00 p.m.

The creation of the Planetary Defense Coordination Office (PDCO) is a logical extension of NASA’s NEO Observations programs, which began nearly two decades ago. Since that program’s inception in 1998, NASA-funded endeavors have discovered more than 98% of all new NEOs. Observatories on Hawai‘i Island and Maui are key to these discoveries and help us better understand the makeup of these celestial vagabonds in our neighborhood.

 

In their presentation, Fast and Landis will share current efforts to detect, track, and characterize comets and asteroids that come close to Earth. They will also discuss the steps that NASA plans to take to deflect a potential asteroid on an impact trajectory.

 

Landis is currently assigned to the NASA Headquarters in Washington, D.C. and is an engineer within the Planetary Science Division, Science Mission Directorate. He’s had a varied career on several NASA space missions including the Hubble Space Telescope, the Rossi X-ray Timing Explorer, the Cassini-Huygens mission to Saturn (and Titan), the Mars Exploration Rovers and the International Space Station. He received his B.S. in Astrophysics from Michigan State University and his M.S. in Space Studies from the University of North Dakota.

 

Dr. Fast manages the Near-Earth Object Observations Program in NASA’s Planetary Defense Coordination Office, where she is also the NASA Infrared Telescope Facility (IRTF) Program Scientist. Fast earned her Ph.D. in Astronomy from the University of Maryland. She studied the atmospheres of Mars, Jupiter and Titan as an astronomer at NASA’s Goddard Space Flight Center before coming to NASA Headquarters in 2011.

Why is it Dark at Night? A Modern Look at Olber’s Paradox

by Brea Aamoth

A Presentation by Dr. Tom Geballe of Gemini Observatory

Date: Fri. March 3
Time: 7:00p.m. – 8:00p.m.
Cost: $10 ($8 for members)

The sky is dark at night —this is a fundamental observational fact of cosmology that can be observed by everyone. This is also fundamental to our existence, to our physiology and to our cultures. The obvious answer to the question “why is it dark at night?” is that the sun is shining on the other side of the Earth, and the light of the distant stars is much weaker than the sun. But how is this possible when there are so many stars that have been shining for so long? And how dark is the sky? Is it dark only to eyes like ours that are sensitive to visible light, or is it also dark to infrared, ultraviolet, x-ray and radio ‘eyes’?

Join us at ‘Imiloa on Friday, March 3 at 7:00 p.m. as Dr. Tom Geballe of Gemini Observatory answers these questions, as well as delving into historical and scientific attempts to understand this simple yet important observation. Dr. Geballe will discuss Olber’s Paradox: a historical argument that states the darkness of the night sky conflicts with the assumption of an infinite and eternal “static universe”. Olber’s Paradox argues that if the universe is populated by an infinite amount of stars, and if the universe has existed for an infinite amount of time, then any sight line from Earth must end at the very bright surface of a star. This paradox states that the night sky should be bright in a static universe, contradicting the observed darkness of night.

.

Dr. Geballe received his Bachelor’s degree in Physics from the University of California at Berkeley and his PhD in Physics from Berkeley. After one postdoctoral year at Berkeley, two years as a Research Fellow at Leiden University in the Netherlands, and four years as a Carnegie Fellow in Pasadena, he moved to Hawaii to join the staff of the United Kingdom Infrared Telescope (UKIRT). In 1987 he became UKIRT’s Astronomer-in-charge, in 1990 its Associate Director, and in 1994 its Head of Operations. In 1998 he accepted a tenured astronomer position at Gemini Observatory, where he is currently employed.
