New recipe for dwarf galaxies: Start with leftover gas
There is more than one way to make a dwarf galaxy, and NASA's Galaxy Evolution Explorer has found a new recipe. view more (2009-02-19)
The Purple Rose of Virgo
ntil now NGC 5584 was just one galaxy among many others, located to the West of the Virgo Cluster. Known only as a number in galaxy surveys, its sheer beauty is now revealed in all its glory in a new VLT image. Since 1 March, this purple cosmic rose also holds the brightest stellar explosion of the year, known as SN 2007af. view more (2007-03-28)
Kiwi astronomers help find icy 'Super Earth' - Life in space discovery a step closer
By designing a variant of an astronomical technique proposed by Einstein, researchers from The University of Auckland and Massey University, together with astronomers from Auckland's Stardome Observatory, have found evidence for a new icy "Super Earth". view more (2006-03-15)
Milky Way's Giant Black Hole Awoke from Slumber 300 Years Ago
Using NASA, Japanese, and European X-ray satellites, a team of Japanese astronomers has discovered that our galaxy's central black hole let loose a powerful flare three centuries ago. view more (2008-04-16)
Scientists elucidate the origin of the darkest galaxies in the universe
Ghostly galaxies composed almost entirely of dark matter speckle the universe. Unlike normal galaxies, these extreme systems contain very few stars and are almost devoid of gas. view more (2007-02-15)
Caltech astronomers describe the bar scene at the beginning of the universe
Bars abound in spiral galaxies today, but this was not always the case. A group of 16 astronomers, led by Kartik Sheth of NASA's Spitzer Science Center at the California Institute of Technology, has found that bars tripled in number over the past seven billion years, indicating that spiral galaxies evolve in shape. view more (2008-07-30)
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)
Oldest stars may shed light on dark matter, researchers report in Science
The universe's earliest stars may hold clues to the nature of dark matter, the mysterious stuff that makes up most of the universe's matter but doesn't interact with light, cosmologists report. view more (2007-09-14)
Really Hot Stars
Spectacular VLT Photos Unveil Mysterious Nebulae Quite a few of the most beautiful objects in the Universe are still shrouded in mystery. Even though most of the nebulae of gas and dust in our vicinity are now rather well understood, there are some which continue to puzzle astronomers. This is the case of a small number of unusual nebulae that... view more... (2003-04-09)
GAMMA RAYS AND DARK MATTER
For a long time it has been known that the Milky Way is surrounded by a (nearly spherical) halo of invisible matter, which contributes at least 90% of the whole galactic mass. Yet, almost nothing is known about the nature of such a dark halo. view more (1999-02-26)
New technique for 'weighing' black holes
ESA's XMM-Newton has helped to find evidence for the existence of controversial Intermediate Mass Black Holes. Scientists used a new, recently proven method for determining the mass of black holes. view more (2007-05-17)
Astronomers use gamma-ray burst to probe star formation in the early universe
The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy. view more (2009-01-07)
Measure the speed of light using Milky Way Stars®
Nothing travels faster than light - it only takes 8 minutes for it to reach the Earth from the nearest star, the Sun, which is 150 million kilometres away. Now anyone can measure this speed - with chocolate stars and a microwave oven! The experiment is described on a new Institute of Physics web resource for teachers about fun physics... view more...

Giant Galaxy Messier 87 finally sized up
Using ESO's Very Large Telescope, astronomers have succeeded in measuring the size of giant galaxy Messier 87 and were surprised to find that its outer parts have been stripped away by still unknown effects. view more (2009-05-21)
UGA astronomers discover surprising shortage of hot gas in famed spiral galaxy NGC 1068
Spiral galaxies are the glitter of the universe. These systems of stars, dust, gas and plasma are held together by gravity but seem to pinwheel across the darkness of space. view more (2006-06-06)
Distant black holes may be source of high-energy cosmic rays
Breakthrough astrophysics research may have established the hitherto mysterious source of exceptionally high-energy cosmic ray emissions, according to recently published research that culminates a project developed by a scientist at the U.S. Department of Energy's (DOE) Argonne National Laboratory. view more (2007-11-12)
Carina Nebula dust pillars harbor embedded stars, says research team
Astronomers using NASA's Spitzer Space Telescope have imaged a giant molecular cloud being shredded by howling stellar winds and searing radiation, exposing a group of towering dust pillars harboring infant stars, according to a University of Colorado at Boulder researcher. view more (2005-05-30)
Astronomers see faintest stars in a globular cluster
Astronomers report in the Aug. 18 issue of the journal Science seeing the faintest stars ever seen in any globular star cluster. The light from these dim stars is only as bright as the light produced by a birthday candle on the moon, as seen from Earth. The astronomers used NASA's Hubble Space Telescope. view more (2006-08-21)
Radio telescopes extend astronomy's best 'yardstick'
Radio astronomers have directly measured the distance to a faraway galaxy, providing a valuable "yardstick" for calibrating large astronomical distances and demonstrating a vital method that could help determine the elusive nature of the mysterious Dark Energy that pervades the Universe. view more (2009-06-09)
Surfing a Black Hole
An international team of astronomers [2], lead by researchers at the Max-Planck Institute for Extraterrestrial Physics (MPE), has directly observed an otherwise normal star orbiting the supermassive black hole at the center of the Milky Way Galaxy. Ten years of painstaking measurements have been crowned by a series of unique images obtained by the... view more... (2002-10-14)
