The Gaia satellite has discovered a unique binary system where one star is ‘eating’ the other, but neither star has any hydrogen, the most common element in the Universe. The system could be an important tool for understanding how binary stars might explode at the end of their lives.
Gaia-ESO data show Milky Way may have formed ‘inside-out’, and provide new insight into Galactic evolution20 Jan 2014
Research on first data release from Gaia-ESO project suggests the Milky Way formed by expanding out from the centre, and reveals new insights into the way our Galaxy was assembled.
A space mission to create the largest, most-accurate, map of the Milky Way in three dimensions has been launched today. Astronomers say the data gathered by the satellite will “revolutionise” our understanding of the galaxy and the universe beyond.
European Space Agency announces broad plan for major space science missions over the next two decades, with Cambridge’s Institute of Astronomy involved at the highest levels.
Astronomers have discovered enormous smooth shapes that look like vapour trails in a gigantic galaxy cluster. These ‘arms’ span half a million light years and provide researchers with clues to a billion years of collisions within the “giant cosmic train wreck” of the Coma cluster.
