XMM-Newton scores 1000 top-class science results
Wednesday, January 25 2006 - 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.

This Supernova Just Won't Fade Away
July 25, 2005 - Scientists have
found that a star that exploded in 1979 is as bright today in X-ray
light as it was when it was discovered years ago, a surprise finding
because such objects usually fade significantly after only a few
months.

Hot spots
on neutron stars
April 22, 2005 -
Hot spots on neutron stars:
Phase variation in the X-ray emissions from three pulsars has been examined using the EPIC instrument on XMM-Newton. In a paper published this week in the Astrophysical Journal scientists reveal that analysis of spectra over the pulsar rotation period has enabled them to track hot spots on the surface of the neutron star.

Jupiter: A cloudy mirror for the Sun?
March 7, 2005 - Astronomers using
the European Space Agency's XMM-Newton telescope have discovered
that observing the giant planet Jupiter may actually give them an
insight in to solar activity on the far side of the Sun! In research
reported in the most recent edition of Geophysical Research Letters,
they discovered that Jupiter's x-ray glow is due to x-rays from
the Sun being reflected back off the planet's atmosphere.

Distant Galaxies Show a
Young Universe
March 2, 2005 - Using ESA's X-ray
observatory XMM-Newton and the European Southern Observatory's Very
Large Telescope, scientists have discovered the most distant massive
structure in the Universe. The data reveal a cluster of hundreds
of galaxies already in place when the Universe was only a third
of its present age. This discovery suggests that the Universe's
hierarchal structure of stars, galaxies and clusters formed quickly
after the big bang, much earlier than astronomers thought.

Dazzling Halos Illuminate Our Dusty
Galaxy
January 26, 2004 - The discovery
of a unique phenomenon: a beautiful set of expanding X-ray halos
surrounding a gamma-ray burst which have never been seen before,
has been announced by an international team of astronomers led by
Dr Simon Vaughan of the University of Leicester. The research has
been accepted for publication in the Astrophysical Journal.
