The American Geophysical Union announced Sept. 13 that five 黑料老司机 faculty members have been elected as new fellows, representing the departments of astronomy, Earth and space sciences, oceanography, global health, and environmental and occupational health sciences.
Twenty scientists and engineers at the 黑料老司机 are among the 38 new members elected to the Washington State Academy of Sciences for 2021, according to a July 15 announcement. New members were chosen for 鈥渢heir outstanding record of scientific and technical achievement, and their willingness to work on behalf of the Academy to bring the best available science to bear on issues within the state of Washington.鈥�
A 黑料老司机-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.
Victoria Meadows, professor of astronomy at the 黑料老司机 and director of the UW’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.
UW 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.
New research from astronomers at the UW uses the intriguing TRAPPIST-1 planetary system as a kind of laboratory to model not the planets themselves, but how the coming James Webb Space Telescope might detect and study their atmospheres, on the path toward looking for life beyond Earth.
A roundup of UW 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.
Not all stars are like the sun, so not all planetary systems can be studied with the same expectations. New research from a 黑料老司机-led team of astronomers gives updated climate models for the seven planets around the star TRAPPIST-1.
Researchers with the UW-led Virtual Planetary Laboratory are central to a group of papers published by NASA researchers today in the journal Astrobiology outlining the history 鈥� and suggesting the future 鈥� of the search for life on exoplanets, or those orbiting stars other than the sun.
Aspects of an otherwise Earthlike planet鈥檚 tilt and orbital dynamics can severely affect its potential habitability 鈥� even triggering abrupt 鈥渟nowball states鈥� where oceans freeze and surface life is impossible, according to new research from UW astronomers.
Victoria Meadows, 黑料老司机 astrobiologist, professor of astronomy and leader of NASA’s UW-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.
The amount of biomass 鈥� life 鈥� in Earth’s ancient oceans may have been limited due to low recycling of the key nutrient phosphorus, according to new research by the 黑料老司机 and the University of St. Andrews in Scotland.
The lead investigator of the research team that discovered Proxima Centauri b, the closest exoplanet, will join UW astrobiologists May 3 to discuss the planet’s potential for life and even the possibility of sending spacecraft to the world.
Recently published research from the UW’s Virtual Planetary Laboratory (VPL) using ancient Earth as a stand-in for hypothetically habitable exoplanets has been highlighted by NASA in a feature article. Leading the research was Giada Arney, who was a UW astronomy doctoral student when doing the work and is now with NASA’s Goddard Spaceflight Center.
The world’s attention is now on Proxima Centauri b, a possibly Earth-like planet about 4.22 light-years away. It’s in its star’s habitable zone — but could it in fact be habitable? If so, the planet evolved very different than Earth, say researchers at the 黑料老司机-based Virtual Planetary Laboratory.
New research from the UW-based Virtual Planetary Laboratory will help astronomers better identify 鈥� and thus rule out 鈥� “false positives” in the search for life beyond Earth.
An atmospheric haze around a faraway planet 鈥� like the one which probably shrouded and cooled the young Earth 鈥� could show that the world is potentially habitable, or even be a sign of life itself.
Astronomers with the 黑料老司机’s Virtual Planetary Laboratory have created the “habitility index for transiting planets” to rank exoplanets to help prioritize which warrant close inspection in the search for life beyond Earth.
Observations of nitrogen in Earth’s atmosphere by a NASA spacecraft 17 million miles away are giving astronomers fresh clues to how that gas might reveal itself on faraway planets, thus aiding in the search for life.
To find life in the universe, it helps to know what it might look like. If there are organisms on other planets that do not rely wholly on photosynthesis 鈥� as some on Earth do not 鈥� how might those worlds appear from light-years away?
The NASA Astrobiology Institute’s Virtual Planetary Laboratory, based at the 黑料老司机, has long brought an interdisciplinary approach to the study of planets and search for life outside our solar system. Now, a new NASA initiative inspired by the UW lab is embracing that same team approach to bring together 10 universities and two research institutions in the ongoing search for life on planets around other stars.
New research by UW astronomer Rory Barnes and co-authors describes possible planetary systems where a gravitational nudge from one planet with just the right orbital configuration and tilt could have a mild to devastating effect on the orbit and climate of another, possibly habitable world.
Planets orbiting close to low-mass stars are prime targets in the search for life. But new research led by an astronomy graduate student at the UW indicates some such planets may have long since lost their chance at hosting life because of intense heat during their formative years.
UW astronomers have developed a new method of gauging the atmospheric pressure of exoplanets, or worlds beyond the solar system, by looking for a certain type of molecule. And if there is life out in space, it may one day be revealed by this method.
In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star鈥檚 light with ice and snow on the planet鈥檚 surface.
