In this week's #SETILive, we discussed Little Red Dots (possibly distant proto-galaxies) and how they may be the birthplaces of prebiotic chemistry. Watch the full interview: https://youtube.com/live/XhgfNxY7aow

In a recent #SETILive, SETI Institute astronomer Dr. Franck Marchis spoke with Cornell University astronomer Abigail Bohl and the Director of Cornell’s Carl Sagan Institute, Dr. Lisa Kaltenegger, about a study identifying 45 specific worlds as the most promising targets for studying planetary habitability. Rather than searching for ‘Earth 2.0,’ the study focuses on habitability.

New research suggests that “little red dots”—compact, distant galaxies—may act as calm environments where complex molecules can form.
Could these “galactic islands” be producing the building blocks of life across the universe?

#ICYMI: On Friday, Franck spoke with Abigail Bohl and Lisa Kaltenegger about the 45 best planets to look for life as we know it. But first, Franck wanted to know what exoplanet system they would visit if they could. The answer? TRAPPIST-1. Watch the full interview: https://youtube.com/live/WGFMT4M_Qnk
And let us know if there's an exoplanet that YOU want to visit! #SETILive

In a recent #SETILive discussion, astrophysicist Dr. Moiya McTier spoke with astrophysicist Anastasios (Andy) Tzanidakis, a final-year astronomy Ph.D. candidate at the University of Washington. They shared evidence for a system called Gaia GIC1 (also referred to as Gaia20ehk), which may represent an ongoing planetary-scale collision.

Next #SETILive: When Galaxies Collide
TODAY, 15 January, 11 am PSTDr. Moiya McTier will explore two new Euclid studies that combine vast sky surveys, machine learning, and multi-wavelength observations to uncover when and why active galactic nuclei (AGN) ignite. The results show that galaxies in the midst of mergers are far more likely to host actively feeding black holes — and that the brightest AGN are almost always found in cosmic collisions.

One of the most exciting stories this year will be the first light science observations of the NSF-DOE Vera C. Rubin Observatory in Chile, which will mark the beginning of its 10-year LSST program.

In our latest #SETILive #podcast, Franck asked Dr. Ariel Graykowski what it meant that an analysis of #Comet3I/ATLAS revealed a lack of water in the coma. Possibly, it meant that CO2 sublimation was cooling the local area around the nucleus and delaying water sublimation since water was detected as well.
