Spidery star factory gets multi-wavelength makeover

This fantastic multi-wavelength view of the highly productive stellar nursery, the Tarantula Nebula, combines data from the Spitzer, Hubble, and Chandra telescopes.

Despite residing in the Large Magellanic Cloud, a galaxy much smaller than ours, the Tarantula is notable because it spans a much larger distance than any known stellar nursery in the entire Local Group of more than 70 galaxies, which includes the Milky Way.

It's a mystery how a stellar nursery - a cloud of gas that churns out new stars - in a modest galaxy manages to outdo nurseries in giants like the Milky Way and Andromeda, but we can still enjoy this new, false-colour image. Red shows infrared light, green shows visible, and blue shows X-rays. The latter arise from gas that gets heated by supernova explosions and stellar winds from hot young stars.

The spidery-looking Tarantula grabbed the spotlight recently when astronomers discovered that it hosts the fastest spinning normal star ever seen, with a rotation rate of 600 kilometres per second. It was also not far from the Tarantula that astronomers saw the famous supernova 1987A explode 25 years ago.

Discovery enters the Smithsonian

Space shuttle Discovery was placed into the Space hanger at the Udvar-Hazy Center at the Smithsonian this week.

Escorting her in were her former Commanders, including the one we met at Kennedy last summer, Fred Gregory (3rd from left).

British Isles from space

(28 March 2012) --- One of the Expedition 30 crew members photographed this night scene while the International Space Station was flying at an altitude approximately 240 miles over the eastern North Atlantic. The night lights of the cities of Ireland, in the foreground, and the United Kingdom, in the back and to the right, are contrasted by the bright sunrise in the background. The greens and purples of the Aurora Borealis are seen along the rest of the horizon.
