2 satellites will narrowly avoid colliding over Pittsburgh on Wednesday

Two defunct satellites will zip past each other at 32,800 mph (14.7 kilometers per second) in the sky over Pittsburgh on Wednesday evening (Jan. 29). If the two satellites were to collide, the debris could endanger spacecraft around the planet. It will be a near miss: LeoLabs, the satellite-tracking company that made the prediction, said […]

How Earth Climate Models Help Scientists Picture Life On Unimaginable Worlds

In a generic brick building on the northwestern edge of NASA’s Goddard Space Flight Center campus in Greenbelt, Maryland, thousands of computers packed in racks the size of vending machines hum in a deafening chorus of data crunching. Day and night, they spit out 7 quadrillion calculations per second. These machines collectively are known as […]

NASA's Kepler Witnesses Vampire Star System Undergoing Super-Outburst

NASA’s Kepler spacecraft was designed to find exoplanets by looking for stars that dim as a planet crosses the star’s face. Fortuitously, the same design makes it ideal for spotting other astronomical transients – objects that brighten or dim over time. A new search of Kepler archival data has uncovered an unusual super-outburst from a […]
