An international team of researchers has used NASA’s James Webb Space Telescope to calculate the amount of heat energy coming from the rocky exoplanet TRAPPIST-1 c.
The result suggests that the planet’s atmosphere – if it exists at all – is extremely thin.
With a dayside temperature of roughly 380 kelvins (about 225 degrees Fahrenheit), TRAPPIST-1 c is now the coolest rocky exoplanet ever…
NASA’s Jet Propulsion Laboratory is well known for landing rovers on Mars, exploring the solar system with robotic probes, and developing sensitive science instruments that observe Earth and other planets. But less well-known is the lab’s cutting-edge work in the digital…
Using data collected by NASA’s Cassini mission, an international team of scientists has discovered phosphorus – an essential chemical element for life – locked inside salt-rich ice grains ejected into space from Enceladus.
The small moon is known to possess a…
After years of intense drought and diminishing groundwater, California just saw its greatest year-over-year water gains in two decades, according to data from the GRACE-FO (Gravity Recovery and Climate Experiment Follow-On) satellite mission, a partnership between NASA and the German Research Centre for Geosciences (GFZ). This past winter’s bonanza of atmospheric rivers alleviated some of the…
Steps taken by NASA, the agency’s Jet Propulsion Laboratory in Southern California, and Caltech, to put the Psyche mission on track for an October 2023 launch have been outstanding, according to an independently appointed review board. NASA and JPL convened the board last…
Triggered by earthquakes, undersea volcanoes, and other Earth-shaking forces, tsunamis can devastate coastal communities. And when it comes to providing advance warning, every second counts. Scientists at NASA’s Jet Propulsion Laboratory are testing a novel approach to…
Four composite images deliver dazzling views from NASA’s Chandra X-ray Observatory and James Webb Space Telescope of two galaxies, a nebula, and a star cluster. Each image combines Chandra’s X-rays – a form of high-energy light – with infrared data from previously released Webb images, both of which are invisible to the unaided eye. Data from NASA’s Hubble Space Telescope (optical light)…
The Mastcam-Z instrument aboard NASA’s Perseverance Mars rover recently collected 152 images while looking deep into Belva Crater, a large impact crater within the far larger Jezero Crater. Stitched into a dramatic mosaic, the results are not only eye-catching, but also…
NASA’s Lunar Flashlight to Fly by Earth
May 17, 2023
NASA’s Lunar Flashlight mission to the Moon has ended, but the briefcase-size spacecraft will soon fly past Earth before heading into deep space. On Tuesday, May 16, at 9:44 p.m. PDT (Wednesday, May 17, at 12:44 a.m. EDT), the CubeSat will pass about 40,000 miles (65,000…
New images taken by NASA’s Perseverance rover may show signs of what was once a rollicking river on Mars, one that was deeper and faster-moving than scientists have ever seen evidence for in the past. The river was part of a network of waterways that flowed into Jezero Crater, the area the rover has been exploring since landing more than two years ago.
Understanding these watery environments…
