| Remnants of an ancient asteroid shed new light on the early solar system Posted: 25 Sep 2020 08:36 AM PDT Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. Geological and geochemical records indicate that the Earth-Moon system experienced a period of frequent and cataclysmic impacts from asteroids and other bodies. It was thought that this period had a relatively sudden onset, but the researchers have found evidence that this bombardment period may have started much earlier, and decreased in intensity over time. |
| Pair of massive baby stars swaddled in salty water vapor Posted: 25 Sep 2020 08:34 AM PDT Astronomers spotted a pair of massive baby stars growing in salty cosmic soup. Each star is shrouded by a gaseous disk which includes molecules of sodium chloride, commonly known as table salt, and heated water vapor. Analyzing the radio emissions from the salt and water, the team found that the disks are counter rotating. It is promising that salt is an excellent marker to explore the immediate surroundings of giant baby stars. |
