The Hubble Space Telescope take a photo of the odd dwarf galaxy blowing huge bubbles of gas, which were created by supernova explosions. The galaxy which known as Holmberg II, is located about 9.8 million light-years from Earth in the M81 galaxy group. Holmberg II isn’t an elegant spiral or a well defined ellipse, it’s a dwarf galaxy with an irregular and unremarkable shape. The new photo is a composite of visible and near-infrared exposures taken using the Wide Field Channel of Hubble’s Advanced Camera for Surveys. In the image is possible to see shock waves from supernovas blasted through space in Holmberg II, heating interstellar gas and blowing it into the intricate shells.
Holmberg II’s odd appearance has earned it a place in Halton Arp’s “Atlas of Peculiar Galaxies,” which catalogs strange and interesting objects throughout the universe. Holmberg II also harbors a superluminous X-ray source, which is found in the middle of three gas bubbles at the top right of the new image. According to researchers this powerful radiation stream may come from an intermediate-mass black hole.
