Explore the 2017 Solar Eclipse

by Imiloa Astronomy Center

View the eclipse from multiple locations and perspectives, moving back and forth in time and space!

In NASA‘s interactive, web-based 3D simulation, you can click anywhere on the Earth to preview your view of the August 21st, 2017 total eclipse!

When utilizing this app, we first see the Earth with the shadow of the moon on it. The largest circle is the part of the moon’s shadow called the penumbra, which will partially block the sun. The tiniest circle along the thin line in the center is called the umbra, and it is the only location where you can see a total eclipse of the sun. Click and drag on the Earth to move it around, or zoom in with your mouse to get close to the surface. You can simply click on any location to see an inset of the sun, and it will show how much the moon will block it during the eclipse. You can click and drag inside the inset window to change the time, or use the vertical time bar on the right side of the screen to go forward and backward over the three hour and twelve minute time frame that the eclipse happens in North America.

You can click on the “plus” button at the bottom of the screen and type in any city you want, and add it to the list of cities, like adding a bookmark. Then you can easily switch between various locations. The simulation is pre-loaded with the views for Kansas City, Los Angeles, and Miami.

Next to the cities list is an icon of the Earth. Click on it to select alternate views, like the perspective from behind the far side of the moon, or have a look at the entire Earth/Moon/Sun system over two years to see why eclipses don’t happen frequently.

A total eclipse of the sun is one of the most awe-inspiring natural phenomena in the world, so be sure to make your plans to see it well in advance!

REMEMBER: DO NOT look directly at the sun during the eclipse without proper solar filters! You could severely damage your eyes.

Utilizing Hawaiian Basalt to Learn How to Build on Other Planets

by Brea Aamoth

‘Imiloa presents Rodrigo Romo, PISCES Program Manager 

Date: Fri. Aug. 18
Time: 7:00 p.m.
Cost: $10, $8 for members (member level discounts apply)

If we are going to build a base on another planet or moon, we will need to learn how to utilize available resources as construction materials. Some of these materials are found right here on Hawai‘i Island, including our Hawaiian basalt. Learn more about the search for quality construction materials at ‘Imiloa’s Maunakea Skies talk with Rodrigo Romo, Program Manager at the Pacific International Space Center for Exploration Systems (PISCES) on Friday, August 18 at 7:00 p.m.


Basalt is a volcanic rock formed from the rapid cooling of basaltic lava. Volcanoes in Hawai‘i primarily erupt basalt, and have a relatively high fluidity that favors the formation of lava flows. “We have conducted chemical analysis on the composition of Hawaiian basalt using samples collected at various locations on Hawai‘i Island,” says Romo. “We’ve found that some of these samples closely resemble lunar regolith (fine dust) in composition. This makes our local basalt an ideal lunar simulant, and we are using it to research how we can harness the basalt found on the Moon as a construction material.”

PISCES has been involved in researching various methods through which Hawaiian basalt can be utilized to produce quality construction materials. This work has been done in collaboration with NASA and Honeybee Robotics, and has led to various research proposals that are currently being evaluated. In his talk, Romo will present an update of the work being done in this field of study.

.

Rodrigo Romo originates from Guadalajara, Mexico where he obtained his degree in Chemical Engineering. He joined PISCES in 2014 as a Project Manager and has over 25 years of experience in Project Management. He has been interested in space exploration and the development of sustainable materials ever since his experience as a crewmember during Biosphere 2’s second manned mission in the Arizona desert in 1994.

.

Maunakea Skies presentations are held on the third Friday of each month. General admission tickets are $10, $8 for members (member level discounts apply). Pre-purchase tickets at ‘Imiloa’s front desk or by phone at 808-932-8901.

.

Member Level Discounts: $8 for UHH/HawCC Student, Kupuna, Individual, Dual, and Family Members; $6 for Patron Members; Free for Silver, Gold, and Corporate Members.

About PISCES:

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.

(First Light image from the Keck Cosmic Web Imager (KCWI) (middle) is of the globular cluster M3 (right).
