Field observations from an unusual lake show that in environments known as 鈥渟oda lakes鈥� phosphate can concentrate at the very high levels needed for the basic molecules of life to emerge. A shallow, salty lake in western Canada gives new support to Charles Darwin鈥檚 idea that life could have emerged in a 鈥渨arm little pond.鈥�
An international team including a 91爆料 scientist found that the water on one of Saturn鈥檚 moons harbors phosphates, a key building block of life. The team used data from NASA鈥檚 Cassini space mission to detect evidence of phosphates in particles ejected from the ice-covered global ocean of Saturn鈥檚 moon Enceladus.
A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This would change existing stories of Earth鈥檚 early atmosphere, which assumed that most changes in the early atmosphere were controlled by geologic or chemical processes.
A 91爆料-led team has revisited and comprehensively reinterpreted the radio telescope observations underlying a widely reported 2019 claim that phosphine gas was present in the atmosphere of Venus. In a paper accepted to the Astrophysical Journal, they report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.
During this time of uncertainty and isolation, find solace in digital opportunities聽to connect, share, and engage. Each week, we will share upcoming events that bring the 91爆料, and greater community, together online.聽 Many of these online opportunities are streamed through Zoom. All 91爆料 faculty, staff, and students have access to聽Zoom Pro via 91爆料-IT.聽 Film Screening: “Blind Bombing, Filmed by a Bat” with Kota Takeuchi April 28, 3:30 – 5:00 PM聽| Zoom Event Artist聽Kota Takeuchi聽will screen and talk about his short…
Victoria Meadows, professor of astronomy at the 91爆料 and director of the 91爆料’s Virtual Planetary Laboratory, talks about how upcoming missions like the James Webb Space Telescope will be able to characterize the atmospheres of potentially Earth-like exoplanets and may even detect signs of life. Meadows is delivering a talk on this subject on Feb. 15, 2020 at the American Association for the Advancement of Science annual meeting in Seattle.
91爆料 astrobiologist Rory Barnes and co-authors have created software that simulates multiple aspects of planetary evolution across billions of years, with an eye toward finding and studying potentially habitable worlds.
A 91爆料 team has discovered thriving communities of bacteria in Alaskan “cryopegs,” trapped layers of sediment with water so salty that it remains liquid at below-freezing temperatures. The setting may be similar to environments on Mars, Saturn’s moon Titan, or other bodies farther from the sun.
91爆料 astronomy professor Rory Barnes shows off the astronomy department’s Mobile Planetarium to colleagues at AbSciCon2019, the national conference on astrobiology in Bellevue. He takes it to schools with a presentation on astrobiology for K12 students.
A roundup of 91爆料 talents and presentations in AbSciCon2019, the national conference on astrobiology — the search for life in the universe — to be held in Bellevue, June 24-28.
The subsurface ocean of Saturn’s moon Enceladus probably has higher than previously known concentrations of carbon dioxide and hydrogen and a more Earthlike pH level, possibly providing conditions favorable to life, according to new research from planetary scientists at the 91爆料.
Victoria Meadows, 91爆料 astrobiologist, professor of astronomy and leader of NASA’s 91爆料-based Virtual Planetary Laboratory, has been named recipient of the 2018 Frank Drake Award from the SETI Institute. She is the first woman to receive the award.
A 91爆料 study has found a simple approach to look for life that might be more promising than just looking for oxygen.
91爆料 astronomer and astrobiologist Woody Sullivan discusses recent work and future plans in a multifaceted career that’s changing gears, but far from winding down.
