Caught in the cobweb
The Tarantula Nebula in the Large Magellanic Cloud (LMC) is one of the most impressive views in the Southern sky. A new, spectacular wide-field colour photo from the ESO La Silla Observatory shows part of this region with many beautiful nebulae of different kinds. They testify to an ongoing history of very vigorous activity, making this area a showcase of dramatic effects caused by the tremendous output of energy from the most massive stars known.

1843 stellar eruption may be new type of star explosion
Eta Carinae, a bright, variable star in the southern sky that is the most luminous known star in the Milky Way Galaxy, underwent a major eruption 145 years ago that may be the first example of a new type of stellar explosion that is much fainter than a supernova and doesn't destroy the star. UC Berkeley astronomer Nathan Smith reached this conclusion after discovering a fast-moving blast wave from the 1843 eruption. (2008-09-10)

Most detailed image of the Crab Nebula
A new Hubble image - among the largest ever produced with the Earth-orbiting observatory - gives the most detailed view so far of the entire Crab Nebula.

Astronomers slice and dice galaxies
New views of star birth and the heart of a spiral galaxy have been seen by a state-of-the-art astronomical instrument on its first night. The new UKIRT Imaging Spectrometer (UIST) has a revolutionary ability to 'slice' any object in the sky into sections, producing a three dimensional view of the conditions throughout entire galaxies in a single observation. UIST has just been installed on the United Kingdom Infrared Telescope (UKIRT) in Hawaii. (2002-10-04)

In McNeil's Nebula, a young star flaunts its X-ray spots
Using combined data from a trio of orbiting X-ray telescopes, including NASA's Chandra X-ray Observatory and the Japan-led Suzaku satellite, astronomers have obtained a rare glimpse of the powerful phenomena that accompany a still-forming star. A new study based on these observations indicates that intense magnetic fields drive torrents of gas into the stellar surface, where they heat large areas to millions of degrees. X-rays emitted by these hot spots betray the newborn star's rapid rotation. (2012-07-03)

New view of doomed star
A new composite image of the Eta Carinae from NASA's Chandra X-ray Observatory and Hubble Space Telescope shows the remnants of a massive eruption from the star during the 1840s. Eta Carinae is a mysterious, extremely bright and unstable star located a mere stone's throw -- astronomically speaking -- from Earth at a distance of only about 7500 light years. The star is thought to be consuming its nuclear fuel at an incredible rate, while quickly drawing closer to its ultimate explosive demise. (2007-06-20)

Scientists solve mystery of odd patterns of oxygen in solar system's earliest rocks
By re-creating conditions in the solar nebula, the swirl of gas that coalesced to form our star, the planets and the remnant rocky debris that circles the Sun as asteroids, the researchers demonstrated that a simple chemical reaction, governed by known physical principles, can generate silicate dust with oxygen anomalies that match those found in the oldest rocks in the solar system. (2013-10-24)

The frugal cosmic ant
Using ESO's Very Large Telescope Interferometer and its unique ability to see small details, astronomers have uncovered a flat, nearly edge-on disc of silicates in the heart of the magnificent Ant Nebula. The disc seems, however, too 'skinny' to explain how the nebula got its intriguing ant-like shape. (2007-09-27)
