Star on a Hubble diet
How heavy can a star be? This conundrum has haunted astronomers for decades. Theory indicates that there should be an upper stellar mass limit somewhere between 120 and 300 solar masses. Even though heavy stars are very bright, measurements of their masses can be complicated. View More (2006-12-12)
Supernova radioisotopes show sun was born in star cluster, scientists say
The death of a massive nearby star billions of years ago offers evidence the sun was born in a star cluster, say astronomers at the University of Illinois at Urbana-Champaign. View More (2006-10-05)
Largest collection of anomalous white dwarfs observed in new Hubble images
Twenty-four unusual stars, 18 of them newly discovered, have been observed in new Hubble telescope images. The stars are white dwarfs, a common type of dead star, but they are odd because they are made of helium rather than the usual carbon and oxygen. This is the first extensive sequence of helium-core white dwarfs to be observed in a globular cluster, a dense swarm of some of the oldest stars... View More (2009-04-23)
Stripped down: Hubble highlights 2 galaxies that are losing it
Ram pressure is the drag force that results when something moves through a fluid - much like the wind you feel in your face when bicycling, even on a still day - and occurs in this context as galaxies orbiting about the centre of the cluster move through the intra-cluster medium, which then sweeps out gas from within the galaxies.

A Simple View Of Gravity Does Not Fully Explain The Distribution Of Stars In Crowded Clusters
Gravity remains the dominant force on large astronomical scales, but when it comes to stars in young star clusters the dynamics in these crowded environments cannot be simply explained by the pull of gravity. View More (2013-02-21)
Discovery of a very massive, isolated star in a nearby galaxy
Astronomy & Astrophysics is publishing the discovery of a very massive, isolated star in a galaxy near our Milky Way. View More (2011-05-25)
Many comets originally formed in other solar systems: Queen's University astronomer
Many of the most well known comets in history, including Halley, Hale-Bopp and McNaught, may have been born in orbit around other stars and not the Sun, according to a new study by Queen's University astronomy professor Martin Duncan and an international team of astronomers. View More (2010-06-11)
Discovery of Giant X-ray Loop Hints at Cosmic Particle Accelerator
Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. The loop, which was observed in X-ray wavelengths, is 15 times the size of the Arches Cluster, a star-forming region close to the centre of the Milky Way. This is the first time that such a distinctive and huge loop structure has been observed. Dr Masaaki... View More (2005-03-31)

Scientists find 'pinwheels' in Quintuplet cluster
Discovery of pinwheel-shaped dust spirals around two of the mysterious cocoon stars in the Quintuplet cluster tells scientists for the first time that they contain a duo of stars instead of just one. View More (2006-08-21)
Hubble data used to look 10 000 years into the future
Astronomers are used to looking millions of years into the past. Now scientists have used the NASA/ESA Hubble Space Telescope to look thousands of years into the future. View More (2010-10-27)
Arachnophobes beware: Hubble snaps close-up of the Tarantula
The wispy arms of the Tarantula Nebula were originally thought to resemble spindly spider legs, giving the nebula its unusual name. View More (2011-03-15)
ESA Director General Salutes China's First Human Space Flight
"Our warmest congratulations to the People's Republic of China on this outstanding achievement" said ESA Director General Jean-Jacques Dordain soon after the successful Shenzou launch. "China becomes the third country to send human beings into space, demonstrating the reliability of its aerospace technology. This mission could open up a new era of wider cooperation in the world's space... View More (2003-10-15)
Success For Early Double Star Launch
A rare event in the history of space exploration took place yesterday (25 July) when the second European-Chinese Double Star spacecraft lifted off a day early from Taiyuan spaceport, west of Beijing, on a Long March 2C rocket. The launch of the spacecraft, officially called Tan Ce 2 (Explorer 2), was brought forward one day to avoid bad weather. Lift off occurred at 08:05:18 BST (07:05:18 GMT or... View More (2004-07-26)
Record-breaking galaxy cluster discovered
A massive galaxy cluster nearly six billion light years from Earth has been discovered with an astounding and unexpected burst of star formation - more prodigious than any galaxy cluster yet observed, an international team of astronomers and NASA announced today. View More (2012-08-16)
Hubble sees faintest stars in a globular cluster
The NASA/ESA Hubble Space Telescope has uncovered what astronomers are reporting as the dimmest stars ever seen in any globular star cluster. View More (2006-08-21)
Details of solar particles penetrating the Earth's environment revealed
Co-ordinated efforts by China/ESA's Double Star and ESA's Cluster spacecraft have allowed scientists to zero in on an area where energetic particles from the Sun are blasting their way through the Earth's magnetic shield. View More (2006-10-04)
The Drifting Star
By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way. View More (2008-04-16)
First view of a newborn millisecond pulsar?
Combining Hubble Space Telescope images with radio observations has revealed a highly unusual system consisting of a fast spinning pulsar and a bloated red companion star. The existence of the system is something of a mystery - the best explanation so far is that we have our first view of a millisecond pulsar just after it has been `spun up` by its red companion star.

Many famous comets originally formed in other solar systems
Many of the most well known comets, including Halley, Hale-Bopp and, most recently, McNaught, may have been born in orbit around other stars, according to a new theory by an international team of astronomers led by a scientist from the Southwest Research Institute (SwRI) in Boulder, Colo.
