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 recent paper published in the October, 2022, Astrophysical Journal 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 Earth and Planetary Sciences at the University of California, Riverside. He earned his undergraduate degrees in physics and astrophysics from the Florida Institute of Technology and his PhD in astronomy and astrobiology from the University of Washington in Seattle.
Dr. Schwieterman studies the climate, atmospheric chemistry, geochemical evolution, and spectral appearance of terrestrial (rocky) planets. His research specifically focuses on the habitability and potential biosignatures of exoplanets.
To learn more about Eddie's research visit his website (www.eddieschwieterman.com) and follow him on Twitter: @nogreenstars.
You can also read more about nitrous oxide as biosignature in the following SciNews article: Nitrous Oxide Could Help Detect Extraterrestrial Life on Exo-Earths.

Viewers who watched/listened to our November 16, 2022, episode may remember that Dr. Leah Jenks told us about high-energy neutrino emissions from NGC 1068 (Messier 77) that were detected by IceCube. 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 flux of neutrinos reaching us from the cosmos, with energies more than a million times those of neutrinos produced at accelerator laboratories. These cosmic neutrinos are astronomical messengers coming from some of the most violent processes in the universe and from the biggest explosions since the Big Bang. We will discuss the IceCube telescope and highlight the recent discoveries that some high-energy neutrinos — and cosmic rays — originate from sources powered by rotating supermassive black holes.
Francis Halzen is a Vilas and Gregory Breit Distinguished Professor of Physics at the University of Wisconsin–Madison.
Born in Belgium, Halzen received his Master’s and PhD degrees from the KUL Leuven, Belgium, and has been on the physics faculty at UW–Madison since 1972; in 2021, Halzen was named a Vilas Research Professor, one of the university’s most prestigious honors. He has been a fellow of the American Physical Society since 1994, and is the recipient of numerous awards, including the 2014 "Smithsonian" American Ingenuity Award, the 2015 Balzan Prize, a 2018 Bruno Pontecorvo Prize, the 2019 IUPAP Yodh Prize, the 2021 Bruno Rossi Prize of the American Astronomical Society, the 2021 Homi Bhabha Award, and honorary doctorates at several universities.
Halzen is the Principal Investigator of IceCube, a cubic-kilometer neutrino telescope buried in the Antarctic ice at the South Pole. IceCube’s first observations of high-energy cosmic neutrinos garnered the 2013 "Physics World" Breakthrough of the Year Award. In September 2017, IceCube detected a high-energy neutrino from the direction of a blazar called TXS 0506+056. This was the first-ever evidence of a source of high-energy cosmic rays, whose origins have been notoriously difficult to pinpoint since they were discovered over one hundred years ago.
Also a skilled science communicator, Halzen travels widely, giving about 20 or more invited talks per year at conferences, workshops, and colloquia. He also gives regular public talks to local and national groups and interviews for television and radio. Halzen is the co-author of "Quarks and Leptons", a classic textbook on modern particle physics that continues to be used extensively throughout college campuses today. He has a large number of publications to his credit and has written or edited several other books. His essay “Antarctic Dreams,” about the early days of AMANDA, IceCube’s precursor, was featured in "The Best American Science Writing 2000".

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 and computer algorithms to examine an ancient manuscript that had been discovered in a Greek Orthodox monastery in Egypt in 2012. The resulting images not only uncovered astronomy-related writings (e.g., Eratosthenes’ star-origin myths and the third-century poem Phaenomena about the constellations,) but also hidden in the manuscript were star coordinates. Could this manuscript include part of Hipparchus' star catalogue?
Tonight we are airing Fraser's prerecorded interview with Dr. Victor Gysembergh, research professor at the French National Scientific Research Centre. Victor is one of the two experts who examined the manuscript images - tune in to hear all about his conclusions.
Victor Gysembergh is a CNRS research professor at the Centre Léon Robin (Sorbonne Université). He is currently working on an edition of the fragments of Eudoxus of Cnidus, as well as on editions of Claudius Ptolemy’s treatise On the Analemma and his recently discovered treatise on the Meteoroscope.
You can read all about this exciting discovery here: https://news.artnet.com/art-world/medieval-parchment-worlds-oldest-star-map-2195744

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 Soviet Vega 1 and Vega 2 balloon missions where each survived just over 46 hours before their batteries ran out. It would seem that baloons are the way to go!
This week we are joined by Dr. Jacob Izraelevitz, Principal Investigator of the JPL project that is developing robotic balloons — currently called aerobots — that will eventually (hopefully) lead to successful exploration of Venus. In July, 2022, a one-third scale prototype aerobot successfully completed two test flights and achieved controlled flight at more than 4000 feet. These flights were coordinated by Near Space Corporation, a commercial provider of high altitude/near space platforms and flight services.
You can read all about this exciting project in the article written by WSH and Universe Today alumnus Ian O'Neill.
Dr. Jacob Izraelevitz is a Robotics Technologist and Group Lead at the NASA Jet Propulsion Laboratory in the Extreme Environment Robotics Group, and is the Principal Investigator of JPL's Variable-Altitude Venus Aerobots development task.
His career at JPL has primarily sat at the interface of controls and fluid mechanics, covering both powered and buoyant aerial platforms for Venus and Mars. Jacob also acts in a systems engineering role for instrument accommodation on the Europa Lander.
Jacob received his Ph.D. and M.S. in Mechanical Engineering from the Massachusetts Institute of Technology in the aerodynamics of flapping wings, and B.S. in Mechanical Engineering from Olin College of Engineering.
To learn more about Jacob and stay up to date with his research, visit his JPL website or find him on LinkedIn.

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 structures while they are still in their infancy, potentially unlocking never-before understood processes that have led to the Universe as we know it today.
This week we are joined by Dr. Andrey Vayner, a member of a multinational team led by Dominika Wylezalek of Heidelberg University (Germany) that has been studying SDSS J165202.64+172852.3, an “extremely red” QUASAR that dates back to the earliest days of the Universe, some 11.5 billion years ago. Using data collected by NIRSpec, JWST's near infrared spectrograph (https://webb.nasa.gov/content/observatory/instruments/nirspec.html), the team has been able to confirm the presence of not just one, but three, companion galaxies of the QUASAR that are actively in the process of merging.
Andrey is a Postdoctoral Fellow at Johns Hopkins University Physics and Astronomy Department. He obtained his Ph.D. from UC San Diego in 2019. He studies how galaxies and supermassive black holes evolve over cosmic time using advanced ground and space-based telescopes. His current focus is on early-release science observations with JWST, studying the most powerful active galactic nuclei that are heavily obscured by dust.

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 of technosignatures still be indicative of life, just not as we know it? This week, we welcome Dr. Sofia Sheikh from the SETI Institute to discuss how the ATA is playing an instrumental role in this research.
Dr. Sofia Z. Sheikh is a radio astronomer and astrobiologist working at the SETI Institute. She obtained her undergraduate degrees in physics and astronomy at UC Berkeley, and has recently returned to the Bay Area with an NSF-ASCEND Postdoctoral Fellowship after getting her PhD in Astronomy and Astrobiology at Penn State. Currently, she is performing SETI searches and studying pulsars and fast radio bursts with the Allen Telescope Array, a 42-dish radio array located in Hat Creek, California.
You can learn more about the Allen Telescope Array (ATA) by visiting their website.

Pulsars have baffled scientists for decades, including how they work and what form matter takes within a pulsar. Using data collected by the Neutron Star Interior Composition Explorer (NICER) Mission between July 2017 and December 2018, scientists have not only been able to make the most precise size measurements of Pulsar J0030+0451 (located 1,100 light-years away in the constellation Pisces), but they have also mapped hotspots located on its surface. This week we are joined by Dr. Zaven Arzoumanian and Dr. Keith Gendreau, members of the Goddard Team that mapped J0030 and co-authors of "Focus on NICER Constraints on the Dense Matter Equation of State" published in the Astrophysical Journal Letters in December, 2019.
Zaven is the Deputy Principal Investigator and Science Lead for NICER.
Keith is Principal Investigator NICER. Be sure to follow him on Twitter: https://twitter.com/keithgendreau

Nothing transcends human differences here on our tiny planet than sharing the wonders of the night sky. For 50 years, Mike Simmons has been sharing and spreading astronomy with the world, both locally and internationally. Tonight, Mike joins us to share his newest venture, Astronomy for Equity, as he continues his calling to share astronomy with local communitites around the world. Astronomy for Equity brings together existing resources, expertise, networks, and communities to create opportunities for STEM growth in marginalized, isolated, and underserved areas.
Mike Simmons is a long-time friend of the WSH. He is probably best known by members of our community for having founded (and lead) Astronomers Without Borders for over 14 years. In 2020, Mike retired from AWB and joined Blue Marble Space Institute of Science as an Affiliate Research Scientist - which allowed him to found Astronomy for Equity. Mike is also on the Board of Directors of the International Dark-Sky Association.
You can learn more about Astronomy for Equity by visiting their webpage. Be sure to also check out their impressive list of advisors which includes such familiar names as Universe Today's Nancy Atkinson, "Bad Astronomer" Phil Plait, and former WSH guest Astronaut Nicole Stott! With these folks on the team, Astronomy for Equity can't help but succeed!
If you are interested in helping Astronomy for Equity, they are currently running a crowdfund campaign to help students in Libya learn Astronomy. If you are so inclined and would like to contribute (no amount is too small!) please go here: https://astro4equity.org/please-help-students-in-libya-learn-astronomy/

On August 5, 2022, a plucky little rover named Curiosity celebrated its 10th Anniversary on the surface of Mars. Since being lowered on Mars that summer day it has continued to exceed all mission expectations. For ten years, Curiosity has called Gale Crater and the foothills of Mount Sharp "home," all while wandering around the name of science and traveling nearly 18 miles (29 kilometers) and ascending 2,050 feet (625 meters). What have we been able to learn about Mars during this decade? And what lies ahead for the "Little Rover that Could?" Join us tonight as Dr. Ashwin Vasavada brings piques our "Curiosity" and answers these questions.
Dr. Ashwin Vasavada is a planetary scientist at the NASA Jet Propulsion Laboratory in Pasadena, California. Currently he is the Project Scientist for NASA's Curiosity rover that began development in 2003 and just completed its tenth year on the surface of Mars. He now leads the international team of scientists as they explore Gale Crater. He also has participated in the operation and analysis of data from several other NASA spacecraft missions, including the Galileo mission to Jupiter, the Cassini mission to Saturn, and the Lunar Reconnaissance Orbiter. He holds a B.S. in Geophysics and Space Physics from UCLA and a Ph.D. in Planetary Science from Caltech.
You can stay up to date with Curiosity by visiting the project's web site and by following it on both Twitter and Instagram.

This week we are super excited to welcome Dr. Moiya McTier to the Weekly Space Hangout - this time as our special guest! In 2019, Moiya joined the Weekly Space Hangout as one of our first Early Career Journalists, and in April, 2021, she extended our WSH tradition of producing PhDs. On August 16th, Moiya's "autobiographical" book, The Milky Way, was published, and this week she is here to tell us all about it.
Moiya grew up in the middle of the woods of rural Pennsylvania without running water. From there, she went to Harvard University where she became the first person in the school’s long history to study both astrophysics and folklore & mythology.
On April 7, 2021, Moiya earned her PhD in astronomy at Columbia University in New York City, after her successful thesis defense. Moiya researched how the Milky Way’s structure influences exoplanet populations. Outside of research, Moiya has written a science fiction novel, designed an exhibit for the New York Hall of Science, and given more than 100 talks and performances about science.
You can learn more about Moiya on her website Moiya McTier. Be sure to follow her on Twitter, Instagram, and Facebook.

The first suspected exoplanet was identified back in 1988, and was then confirmed in 1992. Since then, the rate at which detection/confirmations have been made has been increasing. And JWST has already directly imaged its first exoplanet! What data are we able to gather from here on Earth? What are we able to learn about these planets from the data collected? How does exoplanet geology compare with our own geology here on Earth? Let's find out as we welcome planetary geologist Dr. Paul Byrne, to the WSH.
Paul Byrne received his B.A. in geology, and Ph.D. in planetary geology, from Trinity College Dublin, Ireland. He was a MESSENGER postdoctoral fellow at the Earth and Planets Laboratory of the Carnegie Institution for Science in Washington, DC, and an LPI postdoctoral fellow at the Lunar and Planetary Institute in Houston, Texas. He is an Associate Professor of Earth and Planetary Sciences at Washington University in St. Louis; before coming to WashU, he was an assistant and then associate professor at North Carolina State University.
Paul's research focuses on comparative planetary geology—comparing and contrasting the surfaces and interiors of planetary bodies, including Earth, to understand geological phenomena at the systems level. Byrne’s research projects span the solar system from Mercury to Pluto and, increasingly, to the study of extrasolar planets. He uses remotely sensed data, numerical and physical models, and fieldwork in analogue settings on Earth to understand why planets look the way they do.

NOTE: Due to an unexpected production issue, our audio cuts out at 11:44 for just over one minute, and again at 13:51 for just over 15 seconds. We apologize for this.
Since JWST launched in December, 2022, we have been holding our collective breath as it made its way to its final home at the L2 Lagrange point. Throughout its approximate month-long journey, JWST systematically worked through a complicated series of deployment and commissioning procedures, including the all-critical focusing and alignment of the telescope's 18 primary mirror segments using 132 different actuator motors. On April 29, 2022, it was announced that focusing and alignment had completed successfully. Tonight, we are joined by Lee Feinberg, Optical Telescope Element (OTE) Manager for JWST, who will tell us what this exacting process truly entailed.Lee Feinberg is the NASA Optical Telescope Element (OTE) Manager for the James Webb Space Telescope at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, a role he has been in since 2002. Earlier in his career, Lee was the Assistant Chief for Technology in the Instrument Systems and Technology Division at Goddard and prior to that Lee was part of the optical team that repaired the Hubble Space Telescope on SM1, STIS instrument manager on SM-2, and he co-led the concept study for Wide Field Camera-3.
Lee was a member of the LUVOIR and Habex Science and Technology Definition Teams and focuses his current research on ultra-stable telescopes and segmented space telescopes. Lee is a Society of Photo-Optical Instrumentation Engineers (SPIE) Fellow and a Goddard Space Flight Center Senior Fellow.

This week we are honored to welcome former NASA Deputy Administrator Lori Garver to the Weekly Space Hangout. Her new memoir, Escaping Gravity (Diversion Books, June 21, 2022), offers a "first-hand account of how a handful of revolutionaries managed to outmaneuver the system of political patronage and bureaucracy that threatened the space agency and the future of human spaceflight. From inside NASA, Garver drove changes to policies and programs that enabled competition that challenged the expensive and ineffective traditional systems at the exact time the capabilities and resources of the private sector began to mature."
Lori Garver led the NASA transition team for President-elect Obama and served as Deputy Administrator of NASA from 2009 - 2013. Lori is a Senior Fellow at Harvard Kennedy School’s Belfer Center for Science and International Affairs, an Executive in Residence at Bessemer Venture Partners, and a member of the Board of Directors for Hydrosat.
Garver founded Earthrise Alliance, a philanthropic organization utilizing satellite data to address climate change, and co-founded the Brooke Owens Fellowship, an internship and mentorship program for collegiate women. Previous senior executive positions include former General Manager of the Air Line Pilots Association, Vice President of the Avascent Group, Associate Administrator for Policy at NASA, and Executive Director of the National Space Society. Garver is the recipient of the 2021 Public Service Award for AIAA, the 2021 Heinlein Award for the National Space Society, the 2020 Lifetime Achievement Award for Women in Aerospace, and has been awarded three NASA Distinguished Service Medals.
Lori holds a B.A. in Political Economy from Colorado College and an M.A. in Science, Technology, and Public Policy from George Washington University.

As humanity dreams of exploring destinations both within our own solar system as well as those far beyond, the greatest challenge to be overcome is how to provide effective protection against the inevitable, prolonged exposure to lethal levels of radiation. We all know that Earth's strong magnetic field continually protects us. But can a sufficiently strong magnetic field be generated aboard a spacecraft? 2022 NIAC winner Dr. Elena D'Onghia joins us tonight to discuss a new concept that may just be the solution we need!
Elena is an associate professor at the University of Wisconsin–Madison's Department of Astronomy, and the principal investigator for this innovative concept called CREW HaT which stands for Cosmic Radiation Extended Warding using the Halbach Torus. The project, which has been awarded funding from NASA Innovative Advanced Concepts (NIAC), incorporates superconductive tape technology, a deployable design, and a Halbach Torus (shown in tonight's thumbnail). The Halbach Torus is a circular array of magnets that generates an asymmetric magnetic field with an enhanced magnetic field outside of a spacecraft that diverts cosmic radiation particles and a suppressed magnetic field within the astronaut's habitat.
To learn more about CREW Hat visit their NIAC page here: https://www.nasa.gov/directorates/spacetech/niac/2022/CREW_HaT/
You can also read more about it here: https://phys.org/news/2022-05-magnetic-astronauts-dangerous-space.html
Dr. Elena D'Onghia is an Associate Professor in the Astronomy Department at the University of Wisconsin-Madison. Prior to joining UWM, she was a Postdoctoral Researcher at the Harvard-Smithsonian Center for Astrophysics.
Elena's research combines unique analytic models and high-resolution numerical simulations to get new insights into the dynamical processes that form the stellar skeleton of our Galaxy.
You can learn more about Elena on her UWM faculty page here: http://www.astro.wisc.edu/our-people/faculty/donghia-elena/.
