Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster
There are many galaxies of different shapes and sizes around us today. Roughly half are gas-poor elliptical-shaped galaxies with little new star formation activity, and half are gas-rich spiral and irregular galaxies with high star formation activity. Observations have shown that gas-poor galaxies are most often found near the centre of crowded... view more... (2007-03-05)
Hubble shows 'baby' galaxy is not so young after all
The NASA/ESA Hubble Space Telescope has found out the true nature of a dwarf galaxy that astronomers had for a long time identified as one of the youngest galaxies in the Universe. Astronomers using the NASA/ESA Hubble Space Telescope have made observations of the galaxy I Zwicky 18 which seem to indicate that it is in fact much older and much... view more... (2007-10-17)
Hubble sees magnetic monster in erupting galaxy
The Hubble Space Telescope has found the answer to a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. It is the most striking example of the influence of these immense tentacles of extragalactic magnetic fields, say researchers. view more (2008-08-21)
Young Galaxy's Magnetism Surprises Astronomers
Astronomers have made the first direct measurement of the magnetic field in a young, distant galaxy, and the result is a big surprise. view more (2008-10-02)
XMM-Newton 'spare-time' provides impressive sky survey
For the past four years, while ESA's XMM-Newton X-ray observatory has been slewing between different targets ready for the next observation, it has kept its cameras open and used this spare time to quietly look at the heavens. view more (2006-05-04)
Hubble finds double Einstein ring
The NASA/ESA Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. The double-ring pattern is caused by the complex bending of light from two distant galaxies strung directly behind a foreground massive galaxy, like three beads on a... view more... (2008-01-11)
NASA's Fermi Telescope Detects Gamma-Ray From
Nearby galaxies undergoing a furious pace of star formation also emit lots of gamma rays, say astronomers using NASA's Fermi Gamma-ray Space Telescope. view more (2009-11-03)
Hubble sees dark matter ring in a galaxy cluster
A team of astronomers used the Hubble Space Telescope to find the best evidence yet for the existence of dark matter, present in the form of a ghostly ring in a galaxy cluster. view more (2007-05-17)
VIMOS - a Cosmology Machine for the VLT
Successful Test Observations With Powerful New Instrument at Paranal One of the most fundamental tasks of modern astrophysics is the study of the evolution of the Universe. This is a daunting undertaking that requires extensive observations of large samples of objects in order to produce reasonably detailed maps of the distribution of galaxies in... view more...

New evidence for dark energy in the universe
An international team of astronomers, led by scientists at the University of Manchester have produced new evidence that most of the energy in the Universe is in the form of the mysterious "Dark Energy". The new evidence comes from a 10-year census of the sky for examples of gravitational lenses, which are seen when a galaxy bends the light from a... view more... (2002-11-09)
Astronomers discover new radio signal using large balloon
A team of NASA-funded scientists, including two from UC Santa Barbara, have discovered cosmic radio noise that they find completely unexpected and exciting. view more (2009-01-08)
Skid Marks in the Galaxy - Astronomers localise galactic particle accelerator
Radio galaxies are amongst the most luminous celestial objects - however, they mainly emit radio waves, not light. These occur when electrically charged particles travelling at almost the speed of light are slowed down, thereby losing energy. Until recently it was not known exactly where the particles reach such high speeds. A group of scientists... view more... (2002-10-16)
NASA's Fermi Finds Gamma-ray Galaxy Surprises
Back in June 1991, just before the launch of NASA's Compton Gamma-Ray Observatory, astronomers knew of gamma rays from exactly one galaxy beyond our own. view more (2009-07-15)
Galaxies gone wild!
Interacting galaxies are found throughout the Universe, sometimes as dramatic collisions that trigger bursts of star formation, on other occasions as stealthy mergers that result in new galaxies. view more (2008-04-24)
Study shows clumps and streams of dark matter in inner regions of the Milky Way
Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system. view more (2008-08-07)
Study plunges standard theory of cosmology into crisis
As modern cosmologists rely more and more on the ominous "dark matter" to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance in the last two decades, yet no direct proof could be found that it actually exists. view more (2009-05-06)
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)
NASA'S Webb Telescope Sunshield Preliminary Design Review Complete
The tennis court-sized sunshield built by Northrop Grumman for NASA's James Webb Space Telescope has completed its preliminary design review at the company's Space Technology facility. view more (2008-03-24)
Auger Observatory links highest-energy cosmic rays with violent black holes
Scientists of the Pierre Auger Collaboration, which includes New York University Physics Professor Glennys R. Farrar, have concluded that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth. view more (2007-11-09)
Study sheds new light on early star formation in the universe
A groundbreaking study has provided new insight into the way the first stars were formed at the start of the Universe, some 13 billion years ago. view more (2007-09-14)
