We may be more alone in the universe than we thought. Of the nearly 100 billion galaxies that exist in the observable universe, only 1 in 10 can support life as we know it on Earth. This is the conclusion of a recent study published in the journal Physical Review Letters.
The MUSE (Multi Unit Spectroscopic Explorer) instrument of ESO's VLT (Very Large Telescope) has managed to capture a very striking snapshot for astronomy and not easy to see: that of a spectacular cosmic accident. In the image, the movement of the gas can be observed for the first time as it is ripped from the galaxy ESO 137-001 to be quickly swallowed up by a huge cluster of galaxies.
Astronomers have been puzzled for years by the appearance of a strange object in the center of our galaxy, the Milky Way. Now, a team of scientists from the University of California in Los Angeles (USA) seems to have solved the mystery of the object baptized as "G2": it is a pair of binary stars that would have been orbiting a huge black hole in our galaxy, eventually merging into an extremely large star shrouded in gas and dust. The research has been published in the Astrophysical Journal Letters.
Thanks to data from NASA's Hubble Space Telescope, a team of astronomers has discovered that a dwarf galaxy is home to a supermassive black hole with a mass equivalent to 21 million suns, making it the smallest known galaxy to host a so massive object. This galaxy, which has a mass of 140 million solar masses, is approximately 54 million light years from Earth.
With this Hawaiian name, which means "immense sky", an international team of researchers has named the outline of the enormous supercluster of galaxies that makes up our own Milky Way.
Messier 33, also known as the Triangle Galaxy, is located about 3 million light years distant from Earth, and is the protagonist of the most detailed image ever seen of this galaxy. The photo has been made possible thanks to the VST survey telescope (VLT Survey Telescope), installed at the Paranal Observatory of the European Southern Observatory (ESO) in Chile.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
