As the ice-and-snow rubble known as mélange melts in Antarctica’s ice shelves, rifts can grow and icebergs break off even in the brutal cold of winter.
Dynamic Radioisotope Power Systems may enable lunar science payloads to survive and thrive during the harsh lunar night.
This NASA/ESA Hubble Space Telescope image features two interacting galaxies that are so intertwined, they have a collective name – Arp 91.
The U.S. Forest Service now has a powerful way to view near-real time fire detection from NASA satellite data that they can include in their hourly air quality forecasts.
NASA's Hubble Space Telescope uncovered what appears to be a pair of identical objects that look so weird it took astronomers several years to determine what they are. Turns out they are stretched images of a gravitationally lensed distant galaxy, located more than 11 billion light-years away... Read More
What are some skywatching highlights in October 2021? See several groupings of the Moon, planets, and stars at sunrise and sunset. Then get to know two bright stars that are part of a special group: along with a handful of others, they take turns with Polaris as North Star over thousands of years.... Read More
At the Space Laser Assembly Cleanroom at NASA’s Goddard Space Flight Center, the Laser and Electro-Optics Branch is building lasers for NASA’s Dragonfly mission to Titan and the European Space Agency’s Laser Interferometer Space Antenna, which will measure waves in space-time caused by massive...

Just as ocean waves follow the wind, scientists expected that waves traveling along the magnetosphere should ripple in the direction of the solar wind. But a new study reveals some waves do just the opposite.
This season’s theme is Co-creating a NASA Citizen Science Data Prime. The events in this series are designed to leverage internal and external NASA knowledge to co-create a quick reference list of the data issues to consider and some of the best practices and resources that can inform... Read More
NASA scientist hopes to collect data that can shed light on the masses of free-floating planets.
NASA and the Federal Emergency Management Agency (FEMA) will co-host the Alliances for Climate Action, a virtual series to address rising demand for accurate, timely, and actionable information at a time of rapid global climate change.
Media accreditation is open for the upcoming launch of NASA’s Double Asteroid Redirection Test (DART) mission, an evaluation of technologies for preventing a hazardous asteroid from striking Earth.
What are the Trojan asteroids? These mysterious space rocks have been gravitationally trapped in Jupiter’s orbit around the Sun for billions of years and hold clues to the formation of our solar system.
The CLASP2.1 mission will launch a rocket to measure the magnetic field in a critical slice of the Sun’s atmosphere called the chromosphere.
