The Sun emitted a strong solar flare, peaking at 4:55 p.m. EST, on Dec. 31, 2023. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to …
Editor's Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. In November 2023, NASA's James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by …
Gary Davis is the mission systems engineer for PACE at NASA's Goddard Space Flight Center in Greenbelt, Maryland. What is your favorite ocean or atmospheric related book or movie? I don't know if it's classified as a book, but I do like the Edgar Allan Poe story "A Descent Into the Maelstrom." My favorite ocean …
The Sun emitted a strong solar flare, peaking at 12:02 p.m. EST, on Dec. 14, 2023. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to …
Ivona Cetinić is a biological oceanographer in the Ocean Ecology Lab at NASA's Goddard Space Flight Center in Greenbelt, Maryland. What is your favorite ocean or atmospheric related book or movie? I'm a science fiction fan. Definitely "Abyss." I don't know why, but it's been my favorite ever since I was a kid. I'm sure …
Editor's note: A previous version of this post identified the TMU as the telecommunications unit. It is the telemetry modulation unit. Engineers are working to resolve an issue with one of Voyager 1's three onboard computers, called the flight data system (FDS). The spacecraft is receiving and executing commands sent from Earth; however, the FDS …
Engineers are working to resolve an issue with one of Voyager 1’s three onboard computers, called the flight data system (FDS). The spacecraft is receiving and executing commands sent from Earth; however, the FDS is not communicating properly with one of the probe’s subsystems, called the telemetry modulation unit (TMU).

NASA's Atmospheric Waves Experiment (AWE) has captured initial images of the mesosphere from its perch on the International Space Station. AWE was installed on the Space Station on Nov. 18, and initial commands were sent to the instrument on Nov. 20.
One of NASA's James Webb Space Telescope's science goals is to understand how galaxies in the early universe formed and evolved into much larger galaxies like our own Milky Way. This goal requires that we identify samples of galaxies at different moments in the universe's history to explore how their properties evolve with time. We …
