How the runaway greenhouse gas effect can destroy a planet’s habitability — including Earth’s
Using advanced computer simulations, scientists have shown how easily a runaway greenhouse effect can rapidly transform a habitable planet into a hellish world inhospitable to life. Not only does this research have implications for our understanding of extrasolar planets, or “exoplanets,” but it also offers insight into the human-driven climate crisis on Earth. The team of astronomers from the University of Geneva (UNIGE) and CNRS laboratories of Paris and Bordeaux saw that after initial stages of a planet’s climate transformation, the planet’s atmosphere, structure and cloud coverage get significantly altered,…
Read MoreArtemis II Crew Trains for Emergency Scenarios Ahead of Moon Mission
Credit: NASA/James Blair The four Artemis II astronauts practiced procedures to exit the Orion spacecraft in an emergency during training at NASA’s Johnson Space Center in Houston on Dec. 15. NASA astronaut Christina Koch (foreground) and CSA (Canadian Space Agency) astronaut Jeremy Hansen were assisted by Bill Owens, Artemis II spacesuit technician. The training included exiting both the side and top hatches of the spacecraft to ensure the crew will be ready for potential emergency scenarios upon splashdown in the Pacific Ocean that would require them to leave the capsule…
Read MoreNGC 2264: Telescopes Illuminate ‘Christmas Tree Cluster’
This composite image shows the Christmas Tree Cluster. The blue and white lights (which blink in the animated version of this image) are young stars that give off X-rays detected by NASA’s Chandra X-ray Observatory. Optical data from the National Science Foundation’s WIYN 0.9-meter telescope on Kitt Peak shows gas in the nebula in green, corresponding to the “pine needles” of the tree, and infrared data from the Two Micron All Sky Survey shows foreground and background stars in white. This image has been rotated clockwise by about 160 degrees…
Read MoreSpace weather will drag NASA’s NEOWISE asteroid-hunting probe back to Earth in 2025
After more than a decade of hunting for asteroids and comets, the days of NASA’s NEOWISE mission are officially numbered. NASA’s Jet Propulsion Laboratory in Southern California (JPL) just announced that the NEOWISE mission will come to an end within just a few years. JPL mission planners expect that solar activity will drag the space telescope out of orbit, and to a fiery death in Earth’s atmosphere, by 2025. “The mission has planned for this day a long time,” Joseph Masiero, a planetary scientist at the California Institute of Technology…
Read MoreThe rings of Uranus look positively festive in epic James Webb Space Telescope holiday photo
They may not be the gold rings from “The Twelve Days of Christmas,” but Uranus and its rings stand resplendent in this stunning portrait from the James Webb Space Telescope (JWST). It’s the second image of Uranus that the JWST has captured this year. The first, released in April, was a two-toned affair composed of imagery captured at infrared wavelengths of 1.4 and 3.0 microns. This new image adds extra wavelengths, specifically 2.1 and 4.6 microns, to give a much more complete overview of the seventh planet from the sun. …
Read MoreApproval to Exceed GSA Lodging for LPSC 2024
2 min read Approval to Exceed GSA Lodging for LPSC 2024 This letter from SARA is to issue a waiver for NASA grantees attending LPSC 2024 allowing them to be reimbursed out of their grants for their actual lodging, although it’s expected to be above the approved GSA amount. This waiver does not supersede the travel policy of your institution if it is more restrictive. Note: I have specified grants (including cooperative agreements). This may also apply to those traveling on NASA contracts, but they should communicate with their contracting…

Members of the DSOC team react to the first high-definition streaming video to be sent via laser from deep space on Dec. 11 at NASA’s Jet Propulsion Laboratory. Sent by the DSOC transceiver aboard the Psyche spacecraft, nearly 19 million miles from Earth, the video features a cat named Taters. NASA/JPL-Caltech A computer screen in the mission support area shows Taters the cat in a still from the first high-definition streaming video to be sent via laser from deep space, as well as the incoming data stream delivering the frames…
Read MoreIce Flows on Mars
The surface of Mars is littered with examples of glacier-like landforms. While surface ice deposits are mostly limited to the polar caps, patterns of slow, viscous flow abound in many non-polar regions of Mars. Streamlines that appear as linear ridges in the surface soils and rocky debris are often exposed on top of infilling deposits that coat crater and valley floors. We see such patterns on the surfaces of Earth’s icy glaciers and debris-covered “rock glaciers.” As ice flows downhill, rock and soil are plucked from the surrounding landscape and…
