Biggest 'small' black hole discovered
Discovery of the largest example of a "small" black hole - one formed from the collapse of a single massive star at the end of its lifetime - has led scientists to revaluate of how black holes come into being, according to a report in Nature. view more (2007-10-22)
How Old is the Universe?
Most astronomers would agree that the age of the Universe - the time elapsed since the "Big Bang" - is one of the "holy grails of cosmology". Despite great efforts during recent years, the various estimates of this basic number have resulted in rather diverse values. When derived from current cosmological models, it depends on a number of... view more... (2001-02-06)
A Trio of Super-Earths
Today, at an international conference, a team of European astronomers announced a remarkable breakthrough in the field of extra-solar planets. Using the HARPS instrument at the ESO La Silla Observatory, they have found a triple system of super-Earths around the star HD 40307. view more (2008-06-17)
Carbon atmosphere discovered on neutron star
Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object. view more (2009-11-05)
Neutron stars join the black hole jet set
NASA's Chandra X-ray Observatory has revealed an X-ray jet blasting away from a neutron star in a binary system. view more (2007-06-28)
Giant eruption reveals 'dead' star
An enormous eruption has found its way to Earth after travelling for many thousands of years across space. Studying this blast with ESA's XMM-Newton and Integral space observatories, astronomers have discovered a dead star belonging to a rare group: the magnetars. view more (2009-06-17)
XMM-Newton uncovers a celestial Rosetta stone
ESA's XMM-Newton orbiting X-ray telescope has uncovered a celestial Rosetta stone: the first close-up of a white dwarf star, circling a companion star, that could explode into a particular kind of supernova in a few million years. view more (2009-09-04)
ESA's XMM-Newton makes the first measurement of a dead star's magnetism
Using the superior sensitivity of ESA's X-ray observatory, XMM-Newton, a team of European astronomers has made the first direct measurement of a neutron star's magnetic field. The results provide deep insights into the extreme physics of neutron stars and reveal a new mystery yet to be solved about the end of this star's life. A neutron star is... view more... (2003-06-11)
Shrinking giants, exploding dwarves
When white dwarf stars explode, they leave behind a rapidly expanding cloud of 'stardust' known as a Type Ia supernova. These exploding events, which shine billions of times brighter than our sun, are all presumed to be extremely similar, and thus have been used extensively as cosmological reference beacons to trace distance and the evolution of... view more...

Young Stars in Old Galaxies - a Cosmic Hide and Seek Game
Surprise Discovery with World`s Leading Telescopes Combining data from the NASA/ESA Hubble Space Telescope (HST) and the ESO Very Large Telescope (VLT), a group of European and American astronomers have made an unexpected, major discovery. They have identified a huge number of "young" stellar clusters, only a few billion years old , inside an... view more... (2002-06-26)
XMM-Newton closes in on space`s exotic matter
ESA PR 69-2002. A fraction of a second after the Big Bang, all the primordial soup of matter in the Universe was `broken` into its most fundamental constituents. It was thought to have disappeared forever. However scientists strongly suspect that the exotic soup of dissolved matter can still be found in today`s Universe, in the core of certain... view more...

FISA-99 Symposium EU Research in Reactor SAfety 29 November - 1 December 1999, Luxembourg
Nowadays in the European Union, the ultimate goal of nuclear reactor safety is to render extensive evacuation precautions for populations in the vicinity of the site "practically" unnecessary. This essentially means developing safety systems and operational procedures to respond to the challenge of hypothetical severe accidents, which are... view more... (1999-11-16)
Nature Points the way to a sustainable hydrogen economy
"This is an exciting early step in developing a sustainable system for producing electricity from hydrogen" said Professor Chris Pickett (Associate Head of the Biological Chemistry Department at JIC). "In Nature iron-sulphur enzymes catalyse a range of important chemical reactions that industry can only do by using precious metal... view more... (2005-02-10)
75 percent of athletes' parents let their child skip exams for a game
Three quarters of parents of young athletes let their child forgo an exam for an important game, a new study conducted at the University of Haifa has found. In comparison, only 47% of parents of young musicians will agree to their child choosing a performance over an exam. view more (2008-08-26)
Carbon nanotubes that detect disease-causing mutations developed by Pitt researcher
University of Pittsburgh researcher Alexander Star and colleagues at California-based company Nanomix, Inc., have developed devices made of carbon nanotubes that can find mutations in genes causing hereditary diseases. view more (2006-01-26)
Particles as tracers for the most massive explosions in the Milky Way
Astronomers recently observed a mysterious flux of particles in the universe, and the hope was born that this may be the first observation of the remnants of "dark matter". view more (2009-08-11)
Galaxy cluster smashes distance record
The most distant galaxy cluster yet has been discovered by combining data from NASA's Chandra X-ray Observatory and optical and infrared telescopes. view more (2009-10-23)
ISO satellite investigates dust discs around stars
investigate the dust discs around normal stars. Those few stars which are surrounded by clouds of dust (our own Sun is surrounded by a dust cloud) would form a list of stars which might have orbiting planets - some of which may support life. These stars would be among the first to be investigated by future space missions searching for signs of... view more... (1996-10-31)
Creating the astro-comb to locate Earth-like planets
Thanks to the ability of astronomers to detect the presence of extrasolar planets orbiting distant stars, scientists today are able to examine hundreds of solar systems. view more (2009-05-08)
Galileo's notebooks may reveal secrets of new planet
Galileo knew he had discovered a new planet in 1613, 234 years before its official discovery date, according to a new theory by a University of Melbourne physicist. view more (2009-07-09)
