Hawaii’s Greatest Export

Knowledge is Hawaii’s greatest export. In this talk, we’ll explore highlights of the science that has come from Hawaii over all scientific disciplines and we’ll discover that Hawaii has made major contributions to humankind’s understanding of almost all aspects of the world around us.  We’ll explore Hawaii’s contribution to numerous scientific fields including atmospheric science by examining work done by the National Oceanic and Atmospheric Administration (NOAA)’s Mauna Loa Observatory, earth sciences by highlighting volcanology and the contributions made by the Hawaii Volcano Observatory, and biology by looking at what have learned during the conservation efforts for the ‘Alala.  We’ll conclude with one astronomer’s selection of research highlights that have come out of observatories on Maunakea including black holes, planets around other stars, and what we might learn about these other worlds in the coming decades.

Hosted by Josh Walawender, Support Astronomer, W. M. Keck Observatory

Living off the Martian Land: Solutions for Colonizing Mars

Space exploration and future planetary colonization is exciting to dream about. However, before humankind can venture to the Red Planet and beyond, we have many obstacles to overcome. One major problem is the expense of space travel. The Pacific International Space Center for Exploration Systems (PISCES) is researching how to mitigate costs by creating novel construction materials using the rock and dust found on places like Mars, sparing costly expenses of transporting resources from Earth.

Kavli Lecture Series

The Cosmos in a Heartbeat, presented by Dr. Shane Larson

This Friday, November 9th, in our Cyber CANOE exhibit, we will be live streaming this fascinating series from 3:30-5:00pm. The first 30 participants will have access to smartphone VR headsets compatible with most devices. Come check it out in VR! This event is included in the price of admission.

A human lifetime is more than a hundred million times shorter than the current age of the Universe. Whether you are a professional astronomer, or a casual backyard stargazer, you have only a few decades to drink it all in—to wonder how it works and how you got here.

The cosmos is full of strange happenings that we sometimes are lucky enough to witness because we happened to be paying attention to the stories the Universe is telling us. These tales are carried on bursts of light, showers of subatomic particles, and the faint whisperings of gravity, and every day that passes, we’re getting better at deciphering them.

In our lifetimes, we will only ever have a glimpse of the cosmos. But that glimpse is enough to transform our perceptions in dramatic ways and to answer the oldest questions we have about what the Universe is doing all around us.

Maunakea Skies Astronomy Talk Series: Dancing Galaxies

Dancing Galaxies: how to make new stars, feed massive black holes, and send out very fast electrons

When galaxies collide they take a couple of billion years to do so.  Our Milky Way and Andromeda will merge in the distant future. If you had a few billion years to spare and stare at the night sky you would observe a slow and gracious dance. Stars, gas, dust, and dark matter of the two galaxies affected at first mostly by the gravity of their own galaxies, will change their orbits and structures as they become more affected by the gravity of two, now merging galaxies.

The changing gravitational potential pulls and compresses some of the cold gas which then clump quicker into dense disks that precede the formation of new stars. The new stars then transform their surroundings with impressive outputs of light, energetic particles, metals, and even tiny dust grains.  While some gas will fuel star-formation, other gas will be forced to slow down its rotation, and swirl down into the central super-massive black hole. 

In this presentation we will look at how this scenario was put together based on multi-wavelength, multi-epoch, multi-facilities observations of gravitationally interacting galaxies. We will also discuss some of the remaining burning questions about merging galaxies that keep extragalactic-astronomers glued to their data. 

Presenter Bio - A. Petric immigrated from Romania to New York City at 14, graduated high-school at 16 with the misplaced hope that in college she will figure out how to extract energy from black-holes and also get a job at the United Nations to bring peace and equality for all.  While those goals were not very well informed or feasible, Petric got her PhD in Astrophysics from Columbia University in 2008 studying cosmological dust: how it’s made, how we can find it between galaxies, and how it was not confusing our estimates of dark energy.  After Columbia University, Petric went to the California Institute of Technology to study nearby, gravitationally interacting galaxies and identify which of them were harboring growing super-massive black holes at their cores.  In 2013 Petric moved to Hawaii first as a Gemini Science Fellow and then as the UH resident astronomer at CFHT.  Her current research focuses on how growing super-massive black holes affect the ability of their host galaxies to make new stars. She also has the privilege to teach undergraduate students at the University of Hawaii, Hilo and graduate students at University of Hawaii, Manoa. She also mentored several fantastic students in the last few years, several of whom have gone on to graduate school, and/or are now employed in Astronomy. In her spare time she volunteers for class-room visits, collaborates with local artists to come up with art-astronomy educational activities for kids and adults, works with the Big Island Giving Tree, tries hard not to be the last one in local swim races, and tries even harder to work with organizations that want to bring peace and equality for all.
