NASA's Marshall Space Flight Center The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the sun, it is also extremely volatile and is expected to have at least one supernova explosion in the future. [ Watch the Video: Eta Carinae: Our Neighboring Superstars ] As one of the first objects observed by NASA’s Chandra X-ray Observatory after its launch some 15...

Outburst From Second Brightest Star Modeled In Three Dimensions

[ Watch the Video: Creating The First 3d Model Of Eta Carinae Nebula ] Gerard LeBlond for redOrbit.com - Your Universe Online In the mid-1800s a massive eruption occurred in the binary Eta Carinae, emitting 10 times the sun’s mass and becoming the second brightest star in the sky. Astronomers have developed a high-resolution 3D model of the expanding cloud produced by the outburst, according to NASA. The study team consisted of Thomas Madura from NASA’s Goddard Space Flight...

Blowing Bubbles In The Carina Nebula
2012-06-05 03:24:36

Giant bubbles, towering pillars and cascading clouds of dust and gas fill the star-forming nursery of the Carina Nebula seen here in a stunning new view from Herschel. The Carina Nebula is some 7500 lightyears from Earth and hosts some of the most massive and luminous stars in our Galaxy, including double-star system eta Carinae, which boasts over 100 times the mass of our Sun. The total amount of gas and dust traced by ESA´s Herschel space observatory in this image is equivalent...

Image 1 - Light Echoes Allow Astronomers To Watch 'Great Eruption' Replay
2012-02-15 14:52:36

Astronomers recently got a rare opportunity to view a cosmic event that took place from 1837 to 1858 known as the "Great Eruption." The outburst temporarily made Eta Carinae the second brightest star in the sky during that period. Today's astronomers are able to view the event because some of the light from the eruption took an indirect path to Earth and is just now arriving. The light was heading in a different direction, away from our planet, when it bounced off dust lingering far...

Image 1 - Carina Nebula Stars In Stunning New VLT Photo
2012-02-08 14:05:25

[ Video 1 ] | [ Video 2 ] ESO´s Very Large Telescope has delivered the most detailed infrared image of the Carina Nebula stellar nursery taken so far. Many previously hidden features, scattered across a spectacular celestial landscape of gas, dust and young stars, have emerged. This is one of the most dramatic images ever created by the VLT. Deep in the heart of the southern Milky Way lies a stellar nursery called the Carina Nebula. It is about 7500 light-years from Earth in the...

Image 1 - La Silla Observatory Captures A Pocket Of Star Formation
2012-02-01 11:55:05

[ Watch the Video ] This new view shows a stellar nursery called NGC 3324. It was taken using the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. The intense ultraviolet radiation from several of NGC 3324's hot young stars causes the gas cloud to glow with rich colors and has carved out a cavity in the surrounding gas and dust. NGC 3324 is located in the southern constellation of Carina (The Keel, part of Jason´s ship the Argo) roughly...

Rossi X-Ray Timing Explorer Completes Mission Operations
2012-01-10 07:18:27

After 16 years in space, NASA's Rossi X-ray Timing Explorer (RXTE) has made its last observation. The satellite provided unprecedented views into the extreme environments around white dwarfs, neutron stars and black holes. RXTE sent data from its last science observation to the ground early on Jan. 4. After performing engineering tests, controllers at NASA's Goddard Space Flight Center in Greenbelt, Md., successfully decommissioned the satellite on Jan. 5. RXTE far exceeded its original...

Image 1 - Ancient Stars Hint At Prehistory Of The Milky Way
2011-11-16 03:58:29

Some of the oldest stars in the Milky Way — a kind of stellar fossils in the outer reaches of our galaxy, contain abnormally large amounts of heavy elements like gold, platinum and uranium. Where these large amounts came from has been a mystery for researchers, since they are usually seen in much later generations of stars. Researchers at the Niels Bohr Institute have been studying these ancient stars for several years with ESO's giant telescopes in Chile in order to trace the origin of...

A local supernova factory has recently started production, according to a wealth of new data from NASA's Chandra X-ray Observatory on the Carina Nebula. This discovery may help astronomers better understand how some of the Galaxy's heaviest and youngest stars race through their lives and release newly-forged elements into their surroundings. Located in the Sagittarius-Carina arm of the Milky Way a mere 7,500 light years from Earth, the Carina Nebula has long been a favorite target for...

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...
