Weekly Space Hangout — January 4, 2023: Dr. Eddie Schwieterman Discusses Nitrous Oxide as a Biosignature
Weekly Space Hangout
Historically, scientists using spectrographic analysis to study exoplanet atmospheres have considered oxygen and methane as two key biosignatures when identifying "life-friendly" planets. But could nitrous oxide (N2O) — aka "Laughing Gas" — also be a reliable biosignature? A explains why N2O can — and should — be included as a biosignature gas. Tonight we are pleased to welcome the paper's lead author, Dr. Eddie Schwieterman, astrobiologist at UC Riverside, to discuss why N2O is an indicator of life. Dr. Eddie Schwieterman is an Assistant Professor of Astrobiology in the Department of...

Weekly Space Hangout — December 14, 2022: Chillin' with Dr. Francis Halzen, PI of IceCube
Weekly Space Hangout
Viewers who watched/listened to our November 16, 2022, episode may remember that Dr. Leah Jenks told us about . This week we are pleased to welcome Dr. Francis Halzen, Principal Investigator for IceCube, who will discuss the significance of these detections in understanding how active galaxies "work," and potentially ushering in the age of Neutrino Astronomy. With funding from the National Science Foundation the IceCube project at the South Pole melted eighty-six holes over 1.5 miles deep in the Antarctic icecap to construct an enormous astronomical observatory. The experiment discovered a...

Weekly Space Hangout — December 7, 2022: The Science of the L1527 "Butterfly" with Dr. Karl Stapelfeldt
Weekly Space Hangout
During our November 16th show, Carolyn Collins Petersen introduced us to the hourglass/butterfly of L1527, an image captured by JWST using its onboard NIRCam. (You can read the original story . This week we are joined by Dr. Karl Stapelfeldt, Chief Scientist for NASA's Exoplanet Exploration Program at JPL who will help us understand the science behind this amazing structure. Karl earned a B.S.E. in Aerospace Engineering and Engineering Physics at Princeton University, and a Ph.D. in Astrophysics at Caltech. His career at NASA includes positions at both the Jet Propulsion Laboratory and most...

Weekly Space Hangout — November 23, 2022: Hipparchus' Lost Star Catalogue with Dr. Victor Gysembergh
Weekly Space Hangout
Greek astronomer Hipparchus, who lived in the second century BCE, is considered to be the greatest astronomical observer of his time. Among his achievements are the development of trigonometry, the ability to predict solar eclipses, discovering and measuring the precession of the equinoxes, and, in approximately 135 BCE, the compilation of the first comprehensive star catalogue in the western world. Since that time, scientists have spent centuries searching for Hipparchus' Star Catalogue, but it disappeared and has never been found. Or has it? In 2017, researchers used multispectral imaging...

Weekly Space Hangout — November 16, 2022: Up, Up, & Away with Dr. Jacob Izraelevitz and JPL's Venus Aerial Robotic Balloons
Weekly Space Hangout
Despite the romance associated with Venus for millennia thanks to its having been named after the Roman god of love, Venus has proven to anything BUT romantic - LITERALLY! Combining the toxic and corrosive composition of its atmosphere with the crushing pressure exerted on anything that attempts to venture too far into it, Venus is the last place most of us would choose for a date. These conditions proved to be disastsrous for missions that sent traditional craft to the planet. To date, the only "craft" to have survived for more than a few hours are the 1985 and balloon missions where each...

Weekly Space Hangout — November 9, 2022: Untying an Early "Cosmic Knot" with Dr. Andrey Vayner
Weekly Space Hangout
Since its final commissioning and being placed in service, JWST has been delivering on its promise to provide unprecedented insight into the most distant — and oldest — regions of our Universe. Whether it's providing a new view of our nearby neighbor Jupiter, or sussing out never-before-seen details of the iconic Eagle Nebula and its Pillars of Creation, let's face it - the imagery so far has been nothing less than stunning! But more importantly, the data being collected by JWST's onboard instrumentation are allowing scientists the ability to peer back in time to study the oldest cosmic...

Weekly Space Hangout — November 2, 2022: Revisiting Apollo Photographically with Andy Saunders, Author of Apollo Remastered
Weekly Space Hangout
This week we are airing our prerecorded interview with Andy Saunders, the author and creative force behind the new book "Apollo Remastered." Andy used his talent and expertise to digitally remaster and restore the original flight film from America's first missions to the Moon. Universe Today's own Nancy Atkinson (who is also a WSH alumna,) interviewed Andy this past month, and as a special treat, Nancy is joining us tonight as well. Andy Saunders is a British author, science writer, and one of the world's foremost experts of NASA digital restoration. His photographic work has been exhibited...

Weekly Space Hangout — October 26, 2022: The ATA Searches for Technosignatures with Dr. Sofia Sheikh from the SETI Institute
Weekly Space Hangout
As we discover new exoplanets on an almost daily basis - particularly now that JWST is online - scientists are ramping up their research into identifying those planets that may exhibit traces of life (as we know it.) Scientists use spectrographs to examine the composition of these exoplanet atmospheres looking markers called technosignatures - trace elements that may be indicative of life. What constitutes a technosignature? Does the presence of one or more technosignatures mean that an exoplanet is a strong candidate for hosting life? Can atmospheric markers not included in our current list...
info_outlineTonight we are very excited to welcome Amber Dubill from the Johns Hopkins Applied Physics Laboratory to the WSH. Amber has worked on both IMAP and DART, and also has a keen interest in advanced solar sail design concepts.
Solar sails have long been theorized as being a viable means of spacecraft propulsion — eventually — and we do seem to be moving closer to their being a reality… In June 2019, the Planetary Society succesfully launched their crowdfunded, proof-of-concept LightSail 2, and it is still going strong! In fact, you can check on its current status here.
Meanwhile, in Rochester NY, Dr. Grover Swartzlander from Rochester Institute of Technology (RIT) was developing a new approach to solar sail design - one that could potentially allow spacecraft to photograph the poles of the sun for the first time! In April 2019 RIT and Dr. Swartzlander were awarded a 2019 NIAC Phase 2 award to explore the feasibility of diffractive solar sails!
As a mechanical engineering student at RIT, Amber worked closely with Dr. Swartzlander on the diffractive solar sail design, and their collaboration continues today.
Amber started her experience on low cost, high risk CubeSats space at RIT as a student and at NASA Langley Research Center (LaRC). This evolved into research on advanced technology concepts for spacecraft. She has developed expertise in the use of solar sailing, and has become a champion for diffractive solar sailing through collaboration on NASA Innovative Advanced Concepts.
She continues working to further develop diffractive solar sailing technology: a new type of massless, infinite propulsion, that will enable spacecraft to sail around our Sun and view it like never before. To stay up to date with Amber's research, follow her on LinkedIn as well as on Facebook.
You can learn more about Amber's and Dr. Swartzlander's collaboration in this podcast. You can read more about the NIAC Phase II award for RIT here.
