Galaxy ESO 005-G004This spiral galaxy belongs to a class of galaxies with active nuclei discovered in July 2007. Like Seyfert-galaxies, quasars or blazars, it contains a supermassive black hole, which swallows large amounts of matter from its surrounding and thereby emits strong radiation. Different from those galaxies, this one is hidden behind thick dust and therefore difficult to see. So it's no surprise that this kind of galaxies has been found so late. ESO 005-G004 was one of two of this kind which has been discovered, multiple others are suspected.Constellation: Octans Distance: 80 million light-years Type: Sa D Back: List of the Galaxies 07/31/2007 |
