'Naked-eye' gamma-ray burst was aimed squarely at Earth
Data from satellites and observatories around the globe show a jet from a powerful stellar explosion witnessed March 19 was aimed almost directly at Earth. view more (2008-09-12)
Measurement of stellar age from uranium decay
For the first time, an international team (led by Roger Cayrel, from Paris Observatory), could measure one uranium line in absorption in a star. This observation has several important implications. It is a great discovery, obtained thanks to the high resolution spectrograph UVES, assembled on one of the 8m-diameter telescopes of the Very Large... view more... (2001-02-05)
New boost for Yorkshire bid to host the £1 billion European Spallation Source
The Yorkshire bid to host the £1 billion European Spallation Source (ESS), the most powerful neutron scattering facility in the world, was today given fresh impetus by the official report of the scrutiny session which examines the workings of the CCLRC - the research council charged with advising the Government on large scale research... view more...

Collaborative study successfully applies neutrons to study hydrogen transfer in biological systems
An innovative collaboration among scientists at Los Alamos National Laboratory, Fox Chase Cancer Center and the University of Tennessee has successfully applied neutron diffraction to create a three-dimensional map of the structure of the enzyme D-xylose isomerase. view more (2006-05-16)
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)
NASA scientists identify smallest known black hole
Using a new technique, two NASA scientists have identified the lightest known black hole. With a mass only about 3.8 times greater than our Sun and a diameter of only 15 miles, the black hole lies very close to the minimum size predicted for black holes that originate from dying stars. view more (2008-04-02)
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)
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)
First Image and Spectrum of a Dark Matter Object
HST and VLT Identify MACHO as a Small and Cool Star An international team of astronomers has observed a Dark Matter object directly for the first time. Images and spectra of a MACHO microlens - a nearby dwarf star that gravitationally focuses light from a star in another galaxy - were taken by the NASA/ESA Hubble Space Telescope (HST) and the... view more...

Probing a rare material spin state at NIST
A team of international physicists that includes researchers from the National Institute of Standards and Technology (NIST) has found experimental evidence of a highly sought-after type of arrangement of atomic magnetic moments, or spins, in a series of materials. view more (2007-09-17)
XMM-Newton reveals X-rays from gas streams around young stars
XMM-Newton has surveyed nearly two hundred stars under formation to reveal, contrary to expectations, how streams of matter fall onto the young stars' magnetic atmospheres and radiate X-rays. view more (2007-06-01)
Trigger-happy star formation
A new study from two of NASA's Great Observatories provides fresh insight into how some stars are born, along with a beautiful new image of a stellar nursery in our Galaxy. view more (2009-08-13)
Double Engine for a Nebula
ESO has just released a stunning new image of a field of stars towards the constellation of Carina (the Keel). This striking view is ablaze with a flurry of stars of all colours and brightnesses, some of which are seen against a backdrop of clouds of dust and gas. view more (2009-08-06)
Supernova remnant menagerie
The supernova remnant N 63A is a member of N 63, a star-forming region in the Large Magellanic Cloud (LMC). Visible from the southern hemisphere, the LMC is an irregular galaxy lying 160,000 light-years from our own Milky Way galaxy. view more (2005-06-07)
Bonn astronomers simulate life and death in the universe
Stars always evolve in the universe in large groups, known as clusters. Astronomers distinguish these formations by their age and size. The question of how star clusters are created from interstellar gas clouds and why they then develop in different ways has now been answered by researchers at the Argelander Institute for Astronomy at the... view more...

MAGIC discovers variable very high energy gamma-ray emission from a microquasar
In a recent issue of Science Magazine, the Major Atmospheric Gamma-ray ImagingCherenkov (MAGIC) Telescope has reported the discovery of variable very high energy (VHE) gamma-ray emission from a microquasar. view more (2006-05-19)
Optical vortex could look directly at extrasolar planets
A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. view more (2005-12-01)
Hubble's 17th anniversary -- extreme star birth in the Carina Nebula
Hubble's new view of the Carina Nebula shows the process of star birth at a new level of detail. view more (2007-04-25)
Hubble sees the graceful dance of 2 interacting galaxies
A pair of galaxies, known collectively as Arp 87, is one of hundreds of interacting and merging galaxies known in our nearby Universe. Arp 87 was originally discovered and catalogued by astronomer Halton Arp in the 1970s. Arp's Atlas of Peculiar Galaxies is a compilation of astronomical photographs using the Palomar 200-inch Hale and the 48-inch... view more... (2007-10-31)
