The Week in SpaceNovember 19-25, 2012 Tuning in the Antennae Galaxies The collision of Antennae Galaxies, about 62 million light-years away, was captured by three space telescopes. This composite image combines data from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red). The Antennae galaxies take their name from the long antenna-like “arms” seen in wide-angle views of the system. These features were produced by tidal forces generated in the collision. The collision, which began more than 100 million years ago and is still occurring, has triggered the formation of millions of stars in clouds of dust and gas in the galaxies. The most massive of these young stars have already sped through their evolution in a few million years and exploded as supernovas.Image credit: NASA / ESA / SAO / CXC / JPL-Caltech / STScI Weekly CalendarNovember 19-25, 2012Holidays - Sky Events - Space History Monday 191969: Apollo 12 makes second lunar landing1996: STS-80 Columbia launched1997: STS-87 Columbia launched2005: Hayabusa spacecraft makes first liftoff from an asteroid Tuesday 20First Quarter Moon 9:31 AM ETNeptune 6° south of Moon 1889: Edwin Hubble born1998: Zarya module launched, first element of International Space ...
