A new image from the Hubble Space Telescope is an example of ‘painting with light’. Astronomers use the separated colours produced by oxygen and hydrogen to investigate star-forming processes in the nebula NGC 2080. The colours explain much about the nature of such nebulae. –from the European Space Agency

The completion of satellite missions is something that is marked like the death of an old friend among space techs.

Over the course of three days there in 1994, we saw badgers, mule deer, pronghorn antelope, burrowing owls, ferringous hawks, black tailed prairie dogs, rattlesnakes, and red foxes.
