Cracking the Code of Existence: Universal Questions and Answers from Maunakea

by Brea Aamoth

‘Imiloa presents Dr. Doug Simons of Canada-France-Hawaii Telescope (CFHT)
Date: Fri. Jan. 20
Time: 7pm
Cost: $10, $8 for members (member level discounts apply)

Real progress is being made in the remarkable yet notoriously difficult task of cracking the code of existence itself through advanced mathematics, physics and astronomy. New knowledge streaming from Maunakea’s summit is an essential part of this epic quest. Learn more about Cracking the Code of Existence: Universal Questions and Answers from Maunakea at ‘Imiloa’s Maunakea Skies talk on Friday, January 20 at 7:00 p.m. with Dr. Doug Simons, Executive Director of the Canada-France-Hawaii Telescope (CFHT).

.

Dr. Simons will delve into “precision cosmology,” a term he describes would have earned a chuckle from fellow astronomers when used not long ago. Cosmology studies the structure, evolution and origin of the entire Universe, and requires observations of objects near the edge of the visible Universe—making it increasingly difficult to make real progress. For centuries cosmology measurements have been notoriously incorrect, but times have changed. Measurements made over the past decade, including those using instruments on Maunakea, give real merit to the term “precision cosmology.”

.

Combined with advances in high-energy physics which can replicate conditions of the Big Bang, 21st century cosmology is now yielding insights into some of the most perplexing questions we know how to ask, including “where did the Universe come from?” or, “how can you make something out of nothing?” As we search for the answers to these questions, we are lead to utterly astonishing insights, as we are forced to come to grips with the phenomenally improbable nature of our Universe.

.

Interwoven with the marvels of precision cosmology, Dr. Simons will also share perspectives about the conflict over Maunakea and the challenges between science and culture. This misperception is easily challenged by probing far deeper than terms like ‘sacred’ or ‘science’ allow. These polarizing comfort zones melt away when confronted by fundamental truths spawned not by people, but nature.

.

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. Maunakea Skies planetarium 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.

Solving Jupiter’s Mysteries with Juno and NASA Infrared Telescope Facility

by Emily Peavy

Maunakea Skies Reflection with Dr. John Rayner, Director of NASA Infrared Telescope Facility (IRTF)

‘Imiloa invited Dr. John Rayner, Director of the NASA Infrared Telescope Facility (NASA IRTF) for his planetarium presentation titled Maunakea Skies: Jupiter, Juno and the IRTF. Dr. Rayner shared how his facility is working closely with NASA’s Juno mission to better understand the largest member of our Solar System.

.

Dynamic Duo
NASA’s Juno spacecraft entered a 53-day orbit around Jupiter on July 4, 2016. Launched in 2011, Juno’s mission is to study the makeup of Jupiter’s immense atmosphere and gain a better understanding of how Jupiter was formed. While Juno is getting up close and personal with Jupiter, the NASA IRTF (located on Maunakea) is assisting the mission by carefully observing Jupiter in infrared wavelengths, in doing so NASA IRTF provides context to Juno’s data.

These 8 images were taken with IRTF to assist with the Juno mission. Each image is taken using a different wavelength and thus unlocks different information about Jupiter. 1.58 micron light sees the reflectivity of deep clouds. 1.64, 1.65, and 2.12 microns are sensitive to particles reflecting sunlight. 2.16 microns detect particles in Jupiter’s upper troposphere and lower stratosphere. 2.26 microns is sensitive to the materials near the poles.  3.8 microns detects clouds near 2-3 bars within Jupiter’s atmosphere. While 5.10 detects thermal emission as deeps as 5 bars into Jupiter’s atmosphere. View more of these images taken by NASA IRTF here:  http://junoirtf.space.swri.edu/browse

.

Previous Team Ups and Unanswered Questions
This is not the first time that NASA IRTF gave ground-based context to a spacecraft mission traveling to Jupiter. In 1995, the Galileo mission began its orbit around Jupiter where it studied the moons and clouds of the giant planet. In 2003 Galileo ended his mission by plummeting through the atmosphere of Jupiter to study the makeup and layers of Jupiter’s immense clouds. On December 7, 1995 NASA IRTF carefully observed Jupiter as Galileo began his orbit, the infrared maps created by NASA IRTF accompanied the data collected by this mission. While Galileo provided us with new insight into Jupiter’s clouds, it raised more questions than it answered: What is the source of Jupiter’s immense magnetic field? Does Jupiter have a solid rock/ice core? Could Jupiter have migrated from further out in the solar system triggering the Late Heavy Bombardment? The answers to these questions could greatly affect our current models of planetary formation

.

Juno and Her Experiments
As Juno orbits Jupiter, she will attempt to answer these questions by performing various experiments.  Gravity measurements strive to determine if Jupiter has a rock/ice core. The Microwave Radiometer on the craft will probe the atmosphere and measure water levels in the atmosphere. JEDI, JADE, and Waves will study the magnetic field of Jupiter and determine its connection to the atmosphere. While the UVS and JIRAM will detect chemical “fingerprints” of gases present in the clouds. And the basic JunoCam will take fantastic close up images of the large planet.

.

Members of the public can even help determine what JunoCam will image next by visiting its website.

This science is additionally supported by observations by NASA IRTF, whose insights provide greater context to the flow of data that will come in from Juno. A goal of this team mission to provide a more detailed global map of Jupiter. Unfortunately when Juno entered its initial orbit there were complications which caused the spacecraft to be stuck in a longer (53 day) orbit, instead of the shorter orbits that were originally planned for the mission. While the spacecraft is able to conduct experiments in this 53-day orbit, it does take longer than if it was in its intended orbit. However NASA scientists are working on a solution to fix the long orbit problem.

Categorizing Light and Seeing What’s in Between Stars

by Emily Peavy

Maunakea Skies Reflection with Dr. Mark Rawlings of East Asian Observatory

‘Imiloa welcomed Dr. Mark Rawlings from East Asian Observatory / James Clerk Maxwell Telescope in November where he gave a presentation titled Long Wavelength Eyes on the Cosmos. He discussed how astronomers utilize different types of telescopes and different wavelengths of light to study unique objects in the Universe..

Categorizing Light
Light, scientifically known as Electromagnetic Radiation, comes in many different forms. To understand and differentiate types of light, scientists have created the Electromagnetic Spectrum (EM Spectrum), which organizes light based off of energy and wavelength.

Humans are only able see a small portion of the EM Spectrum with the naked eye. Telescopes such as the James Clerk Maxwell Telescope and UKIRT Telescope allow humans to discover and see deeper portions of the Em Spectrum.

.

Seeing what is between Stars
Spectroscopy is a process which allows scientists to see the “fingerprints” of what is causing light, and which types of materials may be interfering with light from an object. Dr. Rawlings utlizies this science as he studies the Interstellar Medium, the materials that exist between stars in the Milky Way. While the space between stars is mostly empty, there are small particles of dust (hydrocarbons, silicates) and gas. The largest of these dust grains are about the size of the particles that make up cigarette smoke. This is the material that over time is able to collect and form nebulae, stars and planets. The dust grains of the Interstellar Medium can absorb visible light and heat up, causing them to emit light in the infrared portion of the EM Spectrum.

Mysteries of the Interstellar Mediums are often exclusively studied using spectroscopy. One such mystery is the appearance of Diffuse Interstellar Bands (DIBs) in spectra of distant objects. DIBs are features of spectra caused by material in between stars, however the type of material that causes these features has remained a mystery for over 60 years. It is thought that these bands might be caused by hydrocarbons, such as those found in smoke (Polycyclic Aromatic Hydrocarbons) or even fullerene, which is commonly known as buckyballs.”

.

The continuing study of this unique material between stars will help astronomers, such as Dr. Rawlings, provide new perspective on our little corner of the cosmos.

‘Imiloa Presents Dr. John Rayner, Director of IRTF
Date: Fri. Dec. 16
Time: 7pm
Cost: $10, $8 for members (member level discounts apply)

One of the most fascinating elements of modern astronomy is the stream of recent exoplanet discoveries–planets circling other stars. Extensive research and development is currently underway in order to better understand how these planets are formed, as well as discovering the formation of planets within our own solar system. Learn more about the formation of planets and other related science phenomena at ‘Imiloa’s Maunakea Skies talk on Friday, December 16 at 7:00 p.m., presented by Dr. John Rayner, Director of the NASA Infrared Telescope Facility (IRTF) on Maunakea.


Dr. Rayner will also discuss how the NASA IRTF is providing supporting observations for NASA’s own Juno spacecraft, which is currently orbiting Jupiter with the goal of measuring the planet’s overall structure and composition and increasing our understanding of how it was formed. Jupiter is by far the largest planet in the solar system, and knowledge of its properties is key to understanding the formation of the solar system and possibly other planetary systems. Dr. Rayner will describe the Juno mission and the role of this spacecraft in this epic quest for knowledge.

Dr. Rayner obtained his education in the UK with a degree in Physics from Kings College, University of London, and a PhD in astronomical instrumentation from the University of Edinburgh. He has been building infrared instruments at IRTF for the past 27 years and is currently commissioning a high-resolution infrared spectrograph, optimized for observing star and planet-forming disks, planetary atmospheres and comets.

Reflection of October Maunakea Skies with Dr. Masanori Iye

Scientific and Engineering Challenges of the Thirty Meter Telescope: A Perspective from Japan

‘Imiloa invited Dr. Masanori Iye, Thirty Meter Telescope Japan Representative, to give a talk as a part of the monthly lecture series Maunakea Skies. As Professor Emeritus of NAOJ (Subaru telescope), Dr. Iye compared the scientific and engineering challenges of the Subaru telescope to those of the planned Thirty Meter Telescope (TMT).
“It was my honor to have a chance to talk at ‘Imiloa Maunakea Skies. Maunakea is so special for all of us who have a special love to the mountain. I am sure we shall be able to overcome eventually not just the scientific and engineering challenges but also the cultural [challenges],” said Dr. Iye.

The evening began with a brief look at the night sky where the audience compared what is visible with the naked eye verses with a telescope. Dr. Iye began by discussing the challenges with Subaru Telescope throughout its planning and construction. Subaru is a unique observatory, as it pushed the limit of how large a single mirror could be constructed. Unique systems were implemented to correct for astigmatism with the mirror and innovations of adaptive optics technology was also developed to properly subtract out the adverse effects of the atmosphere.

The Thirty Meter Telescope’s mirror will be very different from Subaru’s mirror, as it is simply not possible to build a single mirror that large. However, the design of the mirror will be similar to M. W. Keck Telescopes’ in that it will use multiple segmented mirrors which are precisely designed and aligned to act together as one single large mirror.

Japan assumes the responsibility of building TMT’s main telescope structure using their experience of Subaru’s construction to guide them. Japan is currently producing the mirrors for TMT, with the telescope requiring 492 mirrors total with an additional 82 spares; so far 164 of the 584 required mirrors have been produced.

Astronomers use the term “magnitude” to describe how bright or faint an object is. The magnitude scale is often confusing as bright objects are low numbers, while fainter objects have higher numbers; for example the sun has a magnitude of -26.7, while the star Hikianalia, also known as Spica, has a magnitude of 1.04 as it is much fainter than the sun. The Thirty Meter Telescope is projected to be sensitive to light as faint as 32 magnitude. For comparison, the human eye is sensitive to 6 magnitude while current telescopes are sensitive to 28 magnitude.  Detecting light as faint as 32 magnitude would be the equivalent to seeing a firefly blink on the dark side of the moon.

….

With its increased sensitivity the Thirty Meter Telescope will see closer objects in greater detail, and see new, farther away objects that have never been observed before. As astonomers look farther away into the Universe they are also looking back in time, as it took so long for the light of distant objects to reach us. This will allow astronomers to study the new planets now being discovered around other stars, and gain a better understanding of the Cosmic Dawn of the universe and our own origins.

Long-Wavelength Eyes on the Cosmos: November Maunakea Skies Talk with Dr. Mark Rawlings, Support Scientist at James Clerk Maxwell Telescope (EAO)

by Brea Aamoth

‘Imiloa Presents Dr. Mark Rawlings, Support Scientist at the James Clerk Maxwell Telescope
Date: Fri. Nov. 18
Time: 7pm
Cost: $10, $8 for members (member level discounts apply)

Many remarkable astronomical discoveries have resulted from scientific observations across the realms of the electromagnetic (EM) spectrum that lie beyond the domain of human vision. Learn more about this fascinating technology at ‘Imiloa’s Maunakea Skies talk on Friday, November 18 at 7:00 p.m. with Dr. Mark Rawlings, Support Scientist at the James Clerk Maxwell Telescope (East Asian Observatory).

The electromagnetic spectrum encompasses all different forms of light and energy, ranging from low energy radio waves through visible light that humans can see, to high energy Gamma rays. We take advantage of some of the more familiar parts of the EM spectrum in our day-to-day lives, when we use a microwave to warm up food, or tune in to a local radio station. Other portions of the EM spectrum, such as infrared, radio, and submillimeter wavelengths, allow astronomers to make fascinating discoveries about our Universe. Infrared observations, for example, pierce the cloudy veils of stellar nurseries and offer a view of stars in the process of being born, while radio and submillimeter telescopes allow us to image some of the coldest places in the Universe, and glimpse the tiniest molecules and even the afterglow of the Big Bang itself.

During his talk, Rawlings will focus on telescopes that observe at the longer wavelengths–the radio, submillimeter and infrared ranges–and discuss their complementary roles in observing the ‘interstellar medium,’ the material between stars. Despite being invisible to the human eye, the humble mixture of dust and gas that make up the interstellar medium is a fundamental component of the Universe and is actually central to the formation of galaxies, stars and planets. Come learn about astronomers’ unexpected adventures and ongoing struggles to capture the faintest of signals from distant clouds in deep space.

Rawlings received his Ph.D. from the University of Central Lancashire (UK), specializing in optical and infrared studies of dust and gas in high extinction galactic sightlines, focusing on the role of organic material in diffuse interstellar space. For the past year, he has worked as a Support Scientist at the East Asian Observatory. His primary scientific interests include interstellar dust and gas, star formation and evolved stars.

Scientific and Engineering Challenges of the Thirty Meter Telescope: A Perspective from Japan

by Brea Aamoth

‘Imiloa Presents Dr. Masanori Iye, TMT-Japan Representative
Date: Fri. Oct. 21
Time: 7pm
Cost: $10, $8 for members

While initially planned by institutions in North America, the proposed Thirty Meter Telescope (TMT) has grown into an ambitious multinational partnership involving institutes from Japan, China, India, in addition to the U.S. and Canada. The public is invited to learn more about the Japanese perspective on TMT and the progress and challenges of building this next-generation instrument at ‘Imiloa Astronomy Center’s next Maunakea Skies talk on October 21 at 7:00 p.m., presented by Dr. Masanori Iye, TMT-Japan Representative.

Japan’s interest in the next generation telescope dates back to the completion of the National Astronomical Observatory of Japan’s Subaru Telescope atop Maunakea in 1999, and Subaru’s subsequent campaign to look deep into the history of the Universe, using a unique wide field camera able to spot galaxies at 13 billion light years away. The success of this campaign—highlighted by the 2006 discovery of the most distant galaxy, IOK-1, which held the world record for five years — led to the enthusiastic support of Japan’s participation to TMT.

..

Building on the legacy of Subaru Telescope, Japan has assumed responsibility for designing and building the TMT structure, and providing 576 special glass blanks for the 30 meter primary mirror, with much of the work well underway in Japan. In his presentation, Dr. Iye will discuss in detail the engineering and innovation involved in the building of the TMT, along with the challenges involved. He will also touch on some discoveries the TMT is projected to identify by the late 2020’s. These future discoveries are expected to include the history of the early Universe, when the first stars and galaxies were formed, detailed studies of extrasolar planets and their formation process, and the nature of dark matter and dark energy.

..

Dr. Iye received his Doctorate of Science (Astronomy) at the University of Tokyo. He is now a Professor Emeritus of the National Astronomical Observatory of Japan, and currently serves as the Japan Representative of the TMT project. Among many awards, he is the winner of the Japan Academy Prize and the Imperial Medal with Purple Ribbon for Contributions to Astronomy. Professor Iye has been very active in supporting and expanding astronomy education in Japan, and was the director of 3 award-winning science video films.
