Japanese astronomers say they have discovered the oldest and most distant galaxy in the universe using a telescope on the Big Island of Hawaii, a finding that challenges other “earliest galaxy” claims.
Astronomers working with data from several observatories, including ESA's XMM-Newton, have discovered the most distant, mature galaxy cluster yet.
One of the teams behind ESA's XMM-Newton X-ray mission has unveiled the latest edition of their 2XMM catalogue.
XMM-Newton, the most powerful X-ray observatory ever built and launched into space, marks its 10th anniversary on December 10th.
ESAâ€™s orbiting X-ray observatory XMM-Newton has discovered the most massive cluster of galaxies seen in the distant Universe until now.
XMM-Newton has discovered an exploding star in the Milky Way. Usually that would be important in itself, but this time there is a special twist. Calculations show that the explosion must have been clearly visible to the unaided eye but was missed by the legions of star watchers around the planet.
Astronomers working with XMM-Newton have discovered a new cluster of galaxies, hidden behind a previously identified cluster of galaxies. The recently exposed cosmic giant is apparently just as bright as the first group, but is six times further away.
Thanks to data from ESAâ€™s XMM-Newton X-ray satellite, a team of international scientists found a comet-like ball of gas over a thousand million times the mass of the sun hurling through a distant galaxy cluster over 750 kilometres per second.
ESAâ€™s X-ray observatory, XMM-Newton, has for the first time allowed scientists to study in detail the formation history of galaxy clusters, not only with single arbitrarily selected objects, but with a complete representative sample of clusters.
