Record: fastest flashing star
Dutch researcher Steve van Straaten set a record during his doctoral research. The researcher registered the fastest ever change in the X-ray emission originating from a binary star. The record-breaking binary star consists of a neutron star and a lighter companion star. Astronomer Steve van... view more (2004-05-07)

New Star Systems First of Their Kind
Researchers funded by the National Science Foundation (NSF) announced today in Astrophysical Journal Letters that they have discovered a faraway binary star system that could be the progenitor of a rare type of supernova.   view more (2008-04-02)

Evidence mounts for sun's companion star
he Binary Research Institute (BRI) has found that orbital characteristics of the recently discovered planetoid, "Sedna", demonstrate the possibility that our sun might be part of a binary star system.   view more (2006-04-25)

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)

The missing link in the evolution of magnetic cataclysmic stars?
An international team of astronomers might have discovered the missing link in the evolution of the so-called magnetic cataclysmic variable stars. They determined the spin and orbital periods of the binary star Paloma.   view more (2007-09-17)

Supercomputer simulations shed light on cataclysmic variable flashes.
New supercomputer simulations may help explain periodic bursts of light emitted by compact binary star systems.   view more (2005-03-31)

Mystery of Quintuplet stars in Milky Way solved
For the first time, scientists have identified the cluster of Quintuplet stars in the Milky Way's galactic center, next to the super massive black hole, as massive binary stars nearing the end of their life cycle, solving a mystery that had dogged astronomers for more than 15 years.   view more (2006-08-21)

Integral reveals new class of 'supergiant' X-ray binary stars
ESA's Integral gamma-ray observatory has discovered a new, highly populated class of X-ray fast 'transient' binary stars, undetected in previous observations.   view more (2005-11-17)

Star eats companion
ESA's Integral space observatory, together with NASA's Rossi X-ray Timing Explorer spacecraft, has found a fast-spinning pulsar in the process of devouring its companion.   view more (2005-09-07)

Newly Born Twin Stars Are Far From Identical
Two stars, each with the same mass and in orbit around each other, are twins that one would expect to be identical. So astronomers were surprised when they discovered that twin stars in the Orion Nebula, a well-known stellar nursery 1,500 light years away, were not identical at all.   view more (2008-06-19)

Astronomers find first ever gamma ray clock
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays - the most energetic such signal ever observed.   view more (2006-11-28)

Three satellites needed to bring out 'shy star'
An international team of scientists has uncovered a rare type of neutron star so elusive that it took three satellites to identify it   view more (2005-07-14)

NASA sees orbiting stars flooding space with gravitational waves
A scientist using NASA's Chandra X-ray Observatory has found evidence that two white dwarf stars are orbiting each other in a death grip, destined to merge.   view more (2005-05-30)

Supernova leaves behind mysterious object
Thanks to data from ESA's XMM-Newton satellite, a team of scientists taking a closer look at an object discovered over 25 years ago have found that it is like none other known in our galaxy.   view more (2006-07-10)

Music of the black holes: they all play the same tune
Astronomers at the University of Southampton have uncovered a remarkable connection between the monstrous black holes residing at the hearts of distant galaxies and their comparatively tiny cousins which inhabit star systems in our own Milky Way: they are playing the same tunes. Dr Phil Uttley... view more (2002-04-04)

Hospital star ratings are misleading the public
The Government's star rating system for hospitals is misleading the public, say researchers in this week's BMJ, who found that seriously ill adults fared just as well in trusts with zero stars as in three star hospitals. Comparing data from 102 acute hospital trusts, researchers found that the... view more (2004-01-23)

Voyager data may reveal trajectory of solar system
Nearly 30 years after launch, the two Voyager spacecraft are still operational and returning useful data. In their early years they produced some of the first close up images of the large outer planets.   view more (2006-05-31)

Pulsar find boosts hope for gravity-wave hunters
Neutron star pairs may merge and give off a burst of gravity waves about six times more often than previously thought, scientists report in today's issue of the journal Nature [4 December]. If so, the current generation of gravity-wave detectors might be able to register such an event every year or... view more (2003-12-02)

First detailed pictures of asteroid reveal bizarre system
The first detailed images of a binary asteroid system reveal a bizarre world where the highest points on the surface are actually the lowest, and the two asteroids dance in each other's gravitational pull.   view more (2006-10-13)

Double-star systems cycle between big and small blasts
Certain double, or binary, star systems erupt in full-blown explosions and then flare up with smaller bursts, according to new information gathered by NASA's Galaxy Evolution Explorer (GALEX) and analyzed by a team of astronomers, including postdoctoral researcher Mark Seibert of the Carnegie... view more (2007-03-08)

NASA's Swift Sees Double Supernova in Galaxy
In just the past six weeks, two supernovae have flared up in an obscure galaxy in the constellation Hercules. Never before have astronomers observed two of these powerful stellar explosions occurring in the same galaxy so close together in time.   view more (2007-06-27)

Flares illuminate the secret life of a quiescent black hole
Astronomers probing the intimate details of apparently quiescent stellar black holes have discovered that in reality they are dynamic, lively places, subject to flares that briefly illuminate the whole of the gas disc around the black hole. Their observations are helping to build up a picture of... view more (2002-04-04)

100th Extra-solar planet gives clues to origins of planets
British astronomers, together with Australian and American colleagues, have used the 3.9m Anglo-Australian Telescope [AAT] in New South Wales, Australia to discover a new planet outside our Solar System - the 100th to be detected. The discovery, which is part of a search for solar systems that... view more (2002-09-16)
