This image from NASA’s Hubble Space Telescope captured on October 8, 2022, shows the debris blasted from the surface of Dimorphos 285 hours after the asteroid was intentionally impacted by NASA’s DART spacecraft on September 26. The shape of that tail has changed over time. Scientists are continuing to study this material and how it …

For the first time in more than six months, SpaceX has stacked both stages of its next-generation Starship rocket, creating the largest and most powerful launch vehicle ever fully assembled. It’s not the first time. SpaceX has conducted three other ‘full-stack’ Starship demonstrations: once in August 2021 and again in February and March 2022. But …

Observatories around the world have just detected a colossal flare of extremely energetic radiation described as “record-breaking“. The event first detected on October 9, was so bright that it was initially confused for an event closer to home. Originally dubbed Swift J1913.1+1946it was thought to be a brief flash of X-rays from a not-too-distant source. …

Going to great lengths to shield a data center from cosmic rays, say by lining it with lead, would be eye-wateringly expensive. It’s much easier and cheaper to just keep geographically distributed backups of data. If the worst happens, customers can be shifted over to the backup server, says Grayson. But for some applications, cosmic …
CAPE CANAVERAL, Fla. (AP) – A spacecraft that plowed into a small, harmless asteroid millions of miles away succeeded in shifting its orbit, NASA said Tuesday in announcing the results of its save-the-world test. The space agency attempted the test two weeks ago to see if in the future a killer rock could be nudged …

By Arc Center of Excellence for All Sky Astrophysics in 3D (ASTRO 3D) October 11, 2022 The gravitational lenses might also let us “see” the invisible dark matter that makes up most of the Universe. The dozens of newly identified gravitational lenses could also reveal ancient galaxies. Earlier this year, a machine learning algorithm detected …
