Ingredients for water could be made on surface of moon, a chemical factory

Science Daily Astronomy - Wed, 2019-02-20 12:19
When a stream of charged particles known as the solar wind careens onto the moon's surface at 450 kilometers per second (or nearly 1 million miles per hour), they enrich the moon's surface in ingredients that could make water, scientists have found.

Tidal tails: The beginning of the end of an open star cluster

Science Daily Astronomy - Fri, 2019-02-15 11:03
In the course of their life, open star clusters continuously lose stars to their surroundings. The resulting swath of tidal tails provides a glimpse into the evolution and dissolution of a star cluster. Thus far only tidal tails of massive globular clusters and dwarf galaxies have been discovered in the Milky Way system. In open clusters, this phenomenon existed only in theory. Researchers have now finally verified the existence of such a tidal tail in the star cluster closest to the Sun, the Hyades. An analysis of measurements from the Gaia satellite led to the discovery.

A nearby river of stars

Science Daily Astronomy - Fri, 2019-02-15 09:29
Astronomers have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago.
