Hubble Sees Stars of Steam


Comparatively FEW galaxies POSSESS the far-reaching, luminous spiral arms or brightly glowing center of our galaxy the Milky Way home. In FACT, MOST of the Universe's galaxies look like small, amorphous clouds of steam. One of these galaxies is DDO 82, Captured here in an image from the NASA / ESA Hubble Space Telescope. Compared to the tiny THOUGH Milky Way dwarf galaxies still Contain Such Between A Few million billion stars and A Few.

DDO 82, Also known by the designation UGC 5692, is not without a hint of structure, however.
Astronomers classify it as an "Sm galaxy," or Magellanic spiral galaxy, named after the Large Magellanic Cloud, a dwarf galaxy orbits the Milky Way That. That galaxy, like DDO 82, is said to have one spiral arm.

In the case of DDO 82, gravitational Interactions over STI history discombobulated seem to Have it so That this structure is not as evident caps as in the Large Magellanic Cloud. Accordingly, astronomers Also refer to DDO 82 and others of a similar nature unshapely dwarf irregular galaxies as well.

DDO can be found 82 in the constellation of Ursa Major (the Great Bear) approximately 13 million light-years away. The object is Considered part of the M81 Group of galaxies around three dozen. DDO gets 82 STI STI name from entry number in the David Dunlap Observatory Catalogue. Canadian astronomer Sidney van den Bergh originally compiled this list of dwarf galaxies in 1959.

The image is made up of Exposures taken in visible and infrared light by Hubble's Advanced Camera for Surveys. The field of view is 3.3 arcminutes by 3.3 Approximately.
