Hubble Spies Christmas Ornament

Season's greetings from the Hubble Space Telescope, which spotted this glittery ornament in the sky, shown in a photo released this week.

The vast stellar snow globe, an enormous ball of some 330,000 stars called Messier 92, orbits our own Milky Way galaxy much like a toy train circles underneath a Christmas tree. Astronomers study "globular" clusters such as Messier 92 for clues to the formation of stars.
