Hubble and Spitzer Space Telescopes find 'Lego-block' galaxies in early universe

The NASA/ESA Hubble Space Telescope and the NASA Spitzer Space Telescope have joined forces to discover nine of the smallest, faintest, most compact galaxies ever observed in the distant universe. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a 100 to 1,000 times smaller than our Milky Way Galaxy.

1. Hubble finds strong contender for galaxy distance record
   02-12-2008 · EurekAlert!
   The NASA/ESA Hubble Space Telescope, with a boost from a natural "zoom lens," has found the strongest evidence so far for a galaxy with a redshift significantly above 7. It is likely to be one of the youngest and brightest galaxies ever seen right after the cosmic "dark ages," just 700 million years after the beginning of our universe (redshift ~7.6).

2. Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster
   03-02-2007 · EurekAlert!
   The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster's gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years. The new observations also show one mechanism to form the millions of "homeless" stars seen scattered throughout galaxy clusters.

3. Hubble shows 'baby' galaxy is not so young after all
   10-16-2007 · EurekAlert!
   The NASA/ESA Hubble Space Telescope has found out the true nature of a dwarf galaxy that astronomers had for a long time identified as one of the youngest galaxies in the Universe. Astronomers using the NASA/ESA Hubble Space Telescope have made observations of the galaxy I Zwicky 18 which seem to indicate that it is in fact much older and much farther away than previously thought.

4. Monster galaxy pileup sighted
   08-06-2007 · EurekAlert!
   Four galaxies are slamming into each other and kicking up billions of stars in one of the largest cosmic smash-ups ever observed.The clashing galaxies, spotted by NASA's Spitzer Space Telescope and the WIYN Telescope, will eventually merge into a single, behemoth galaxy up to 10 times as massive as our own Milky Way. This rare sighting provides an unprecedented look at how the most massive galaxies in the universe form.

5. NIST math technique opens clearer window on universe
   12-08-2006 · EurekAlert!
   A fast, efficient image enhancement technique developed at NIST and originally applied to improving monochrome microscope images has proved itself equally effective at the other end of the scale -- sharpening details on color images of distant galaxies produced by the Hubble Space Telescope.

6. Hubble finds double Einstein ring
   01-10-2008 · EurekAlert!
   The NASA/ESA Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. The double-ring pattern is caused by the complex bending of light from two distant galaxies strung directly behind a foreground massive galaxy, like three beads on a string.

7. The violent lives of galaxies: Caught in the cosmic matter web
   01-10-2008 · EurekAlert!
   Astronomers are using the NASA/ESA Hubble Space Telescope to dissect one of the largest structures in the Universe as part of a quest to understand the violent lives of galaxies. Hubble is providing indirect evidence of unseen dark matter tugging on galaxies in the crowded, rough-and-tumble environment of a massive supercluster of hundreds of galaxies.

10. Hubble photographs grand spiral galaxy Messier 81
    05-29-2007 · EurekAlert!
    The sharpest image ever taken of the large "grand design" spiral galaxy Messier 81 is being released today. The image, constructed from a series of images taken with NASA/ESA Hubble Space Telescope, is among the largest ever released. Messier 81 is one of the brightest galaxies that can be seen from the Earth.
