    Weekly Space Hangout — January 4, 2023: Dr. Eddie Schwieterman Discusses Nitrous Oxide as a Biosignature
    2023/01/05

    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.

    Weekly Space Hangout — December 14, 2022: Chillin' with Dr. Francis Halzen, PI of IceCube
    2022/12/15
    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".
