A giant star in a faraway galaxy recently ended its life with a dust-shrouded whimper instead of the more typical bang. Ohio State University researchers suspect that this odd event -- the first one of its kind ever viewed by astronomers "“ was more common early in the universe. It also hints at what we would see if the brightest star system in our galaxy became a supernova. In a paper published online in the Astrophysical Journal, Christopher Kochanek, a professor of astronomy at Ohio...

Team led by University of Leicester confirm presence of ultra-bright object in nearby galaxy A group of international astronomers in the UK, France and the USA, led by the University of Leicester, have found proof to confirm the distance and brightness of the most extreme ultra-luminous X-ray source, which may herald a new type of Black Hole. The X-ray source, HLX-1, is the most extreme member of an extraordinary class of objects "“ the ultra-luminous X-ray sources "“ and is...

A spectacular new image from ESO's Wide Field Imager at the La Silla Observatory in Chile shows the brilliant and unusual star WR 22 and its colorful surroundings. WR 22 is a very hot and bright star that is shedding its atmosphere into space at a rate many millions of times faster than the Sun. It lies in the outer part of the dramatic Carina Nebula from which it formed. Very massive stars live fast and die young. Some of these stellar beacons have such intense radiation passing through...

Some might see a blood-red jellyfish in a forest of seaweed, while others might see a big, red eye or a pair of lips. In fact, the red-colored object in this new infrared image from NASA's Wide-field Infrared Survey Explorer (WISE) is a sphere of stellar innards, blown out from a humongous star. The star (white dot in center of red ring) is one of the most massive stellar residents of our Milky Way galaxy. Objects like this are called Wolf-Rayet stars, after the astronomers who found the...

In the past decade, robotic telescopes have turned astronomers' attention to scads of strange exploding stars, one-offs that may or may not point to new and unusual physics. But supernova (SN) 2005E, discovered five years ago by the University of California, Berkeley's Katzman Automatic Imaging Telescope (KAIT), is one of eight known "calcium-rich supernovae" that seem to stand out as horses of a different color. "With the sheer numbers of supernovae we're detecting, we're discovering weird...

The young star cluster Trumpler 14 is revealed in another stunning ESO image. The amount of exquisite detail seen in this portrait, which beautifully reveals the life of a large family of stars, is due to the Multi-conjugate Adaptive optics Demonstrator (MAD) on ESO's Very Large Telescope. Never before has such a large patch of sky been imaged using adaptive optics [1], a technique by which astronomers are able to remove most of the atmosphere's blurring effects. Noted for harboring Eta...

NASA's Hubble Space Telescope has identified a star that was one million times brighter than the sun before it exploded as a supernova in 2005. According to current theories of stellar evolution, the star should not have self-destructed so early in its life. "This might mean that we are fundamentally wrong about the evolution of massive stars, and that theories need revising," says Avishay Gal-Yam of the Weizmann Institute of Science, Rehovot, Israel. The doomed star, which is estimated to...

The latest ESO image reveals amazing detail in the intricate structures of one of the largest and brightest nebulae in the sky, the Carina Nebula (NGC 3372), where strong winds and powerful radiation from an armada of massive stars are creating havoc in the large cloud of dust and gas from which the stars were born. The large and beautiful image displays the full variety of this impressive skyscape, spattered with clusters of young stars, large nebulae of dust and gas, dust pillars,...

A new image released by ESO shows the amazing intricacies of a vast stellar nursery, which goes by the name of Gum 29. In the center, a small cluster of stars "” called Westerlund 2 "” has been found to be the home of one of the most massive double star systems known to astronomers. Gum 29 is a huge region of hydrogen gas that has been stripped of its electrons (ionized) by the intense radiation of the hot young stars located at its center. Astronomers call this an HII...

Astronomers have confirmed the weight of the most massive star in the galaxy. This behemoth, estimated to be roughly 116 times the mass of the sun, dwarfs most other stars in the galaxy. In fact, the next most massive star is about 89 solar masses, and it is a gravitationally bound sister to the record setter. The next most massive ever weighed is 83 solar masses. Theory holds that stars can be up to about 150 solar masses. Discovery of the record-setting stars were first...

Eta Carinae -- Eta Carinae is a very large (100-150 times as much mass as the Sun) and bright (about 4 million times as bright) star, in the constellation Carina (right ascension 10 h 45.1 m, declination -5941m). The star is surrounded by a large, bright nebula, known as the Eta Carinae Nebula, the Keyhole Nebula, or NGC3372 One remarkable aspect of Eta Carinae is its changing brightness. When it was first catalogued in 1677 by Edmond Halley, it was of the 4th magnitude, but later it...
