A Hyper Velocity Star Found with an Exoplanet Hanging on for Dear Life

Hypervelocity stars have been seen before but NASA scientists have just identified a potential record-breaking exoplanet system. They found a hypervelocity star that has a super-Neptune exoplanet in orbit around it. This discovery could reshape our understanding of planetary and orbital mechanics. Understanding more about these fascinating high velocity stars challenges current models of stellar … Read more

NASA Tests Drones to Provide Micrometeorology, Aid in Fire Response

Robert Mcswain

In Aug. 2024, a team of NASA researchers and partners gathered in Missoula, to test new drone-based technology for localized forecasting, or micrometeorology. Researchers attached wind sensors to a drone, NASA’s Alta X quadcopter, aiming to provide precise and sustainable meteorological data to help predict fire behavior. Wildfires are increasing in number and severity around … Read more

Curiosity’s Other Important Job: Studying Martian Clouds

This figure from the paper shows iridescent clouds in cylindrical projections. Each image was taken on a separate day. (d) is twice the resolution of the others. (e) shows a corona in the clouds caused by low variance in CO2 ice particle size. Image Credit: Lemmon et al. 2024.

MSL Curiosity is primarily a rockhound. It’s at Gale Crater, examining the rocks there and on Mt. Sharp, which sits in the middle of the crater and rises 5.5 km above the crater floor. But Curiosity is also a skywatcher, and its primary camera, Mastcam, was built with Martian clouds in mind. When the sun … Read more

‘It was a miracle.’ Amazing tales of dead spacecraft that came back to life

The CIRBE cubesat in the clean room at the University of Boulder, Colorado.

The hulk of metal moved silently through space, high above the blue Earth. Power no longer coursed through its wires, its instruments were dead to the outside universe, and its communications antenna was silent. To all intents and purposes it was deceased, and almost everyone back home had given up on it. Almost everyone. Despite … Read more

Juvenile sea turtles are active swimmers! Video via EarthSky. Scientists have long thought that young sea turtles – after hatching on the shore and making their way into the ocean – drifted passively on currents. But the University of Florida said on February 6, 2025, that these juvenile sea turtles might be active swimmers. A … Read more

New method to cryopreserve drone semen

Bee on a plant with yellow background.

Bee-reaking news: Belgian scientists have developed a simple method to cryopreserve the semen of drones, the male equivalent of honey bees (Apis mellifera). As part of the FreezeBEE project at the University of Liège, the researchers then thawed the semen and successfully artificially inseminated queens. It resulted in a female brood with an equivalent viability to … Read more
