Thanks to data from ESA’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.

Deep observations of two X-ray bright clusters of galaxies with ESA’s XMM-Newton satellite allowed a group of international astronomers to measure their chemical composition with an unprecedented accuracy.

For the past four years, while ESA’s XMM-Newton X-ray observatory has been slewing between different targets ready for the next observation, it has kept its cameras open and used this spare time to quietly look at the heavens.

Using data from ESA's XMM-Newton X-ray observatory, an international group of astrophysicists discovered that one spinning neutron star doesn’t appear to be the stable rotator scientists would expect.

Now an innovative new approach analyses X-rays detected during the times that the satellite manoeuvres between targets - originally considered to be unusable periods - to reveal some 4,000 intensely brilliant X-ray stars and galaxies.

ESA's XMM-Newton has seen vast clouds of superheated gas, whirling around miniature stars and escaping from being devoured by the stars’ enormous gravitational fields - giving a new insight into the eating habits of the galaxy's 'cannibal' stars.

Astronomers have witnessed a never-seen-before event in observations by ESA’s XMM-Newton spacecraft - a collision between a pulsar and a ring of gas around a neighbouring star.

In December 2005, ESA's highly successful XMM-Newton mission was formally given a four-year extension. The longer life necessitated a first-ever in-flight upgrade to the spacecraft's mission control software.

XMM-Newton, ESA's X-ray observatory, continues its quest for the unknown. This month, after five years of operations, the mission saw the publication of its 1000th scientific paper, corresponding to an equivalent number of results, in top-class scientific journals. This is not the only record-breaking figure for this X-ray 'hunter' mission.

In the most comprehensive study of Sagittarius A* (Sgr A*), the enigmatic supermassive black hole in the center of the Milky Way Galaxy, astronomers -- using nine ground and space-based telescopes including the Hubble Space Telescope and the XMM-Newton X-ray Observatory -- have discovered that Sgr A* produces rapid flares close to the innermost region of the black hole in many different wavelengths and that these emissions go up and down together.


Word of the Day
pawl
  • A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
The word 'pawl' probably comes from a Latin word meaning 'stake'.
