At the center of the smallest galaxy ever observed, there is a gigantic black hole, with a mass 21 million times that of the Sun. The discovery, published in the journal Nature, suggests that blacks holes in the universe may be much more common than you think. Indeed, it is the first time that a black hole of this size is found at the center of a dwarf galaxy. To observe the black hole in the galaxy called M60-UCD1, was the international group of astronomers led by Anil Seth, the American College of Utah. “M60-UCD1 is the smallest brightest galaxy as we know it and the center has a super massive black hole,” said Seth.

Astronomers have discovered the black hole using data collected by the telescope Gemini North Observatory on Mauna Kea, Hawaii, and those of the Hubble Space Telescope. According to researchers from many other small galaxies could host gigantic blacks holes: such structures may be the remains of frightful collisions between galaxies. “One time – said Seth – the small galaxy M60-UCD1 was very large and had about 10 billion stars. Perhaps 10 billion years ago has grown too close to the center of a galaxy even bigger, that he tore his stars. ” Located about 54 million light years from Earth (approximately 320 billion billion kilometers), the galaxy M60-UCD1 revolves around a huge galaxy called M60, in the center of which is a super-massive black hole, equivalent to 4.5 billion times the mass of our Sun, which will eventually merge with the black hole in the dwarf galaxy.
