Astronomers found evolutionary links that connect three well-known star clusters. The Orion Nebular Cluster, the Pleiades, and the Hyades are located roughly in the same region in space, but have different ages. New research shows that they're connected and have similar origins.

Lunar regolith is the crushed up volcanic rock that buries the surface of the Moon. Remote observations and sample analysis have shown there are trace amounts of water ice mixed in with the regolith, which can be extracted. By mixing this water with CO2 exhaled by astronauts, scientists have demonstrated this can be turned into hydrogen gas and carbon monoxide. This can then be turned into fuels and oxygen to support the astronauts. Everything we need is there on the Moon. We just need to learn how to use it.
