| Carbon dioxide-rich liquid water in ancient meteorite Posted: 21 Apr 2021 12:12 PM PDT Scientists detect small pockets of carbon dioxide-rich liquid water in a meteorite dating from the early solar system. |
| Bubble with titanium trigger titanic explosions Posted: 21 Apr 2021 09:45 AM PDT Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA's Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode. |
| Enormous flare from sun's nearest neighbor breaks records Posted: 21 Apr 2021 09:45 AM PDT On May 1, 2019, researchers observed a record-setting flare from the star Proxima Centauri -- a burst of energy roughly 100 times more powerful than any similar event seen from Earth's sun. |
| Outback radio telescope discovers dense, spinning, dead star Posted: 21 Apr 2021 06:25 AM PDT Astronomers have discovered a pulsar -- a dense and rapidly spinning neutron star sending radio waves into the cosmos -- using a low-frequency radio telescope in outback Australia. The new pulsar is located more than 3,000 light-years from Earth and spins about once every second. Pulsars are used by astronomers for applications including testing the laws of physics under extreme conditions. |
