NASA -- Scientists using NASA's Far Ultraviolet Spectroscopic Explorer satellite made the first direct detection of a companion star of Eta Carinae. Eta Carinae is one of the most massive and unusual stars in the Milky Way galaxy. The detection was made possible by the high temperature of the companion star and the unique sensitivity of the satellite at the shortest ultraviolet wavelengths. Eta Carinae is an unstable star thought to be rapidly approaching the final stage of its life. It is...

Recent Chandra observations have revealed new details about the fiery ring surrounding the stellar explosion that produced Supernova 1987A. The data give insight into the behavior of the doomed star in the years before it exploded, and indicate that the predicted spectacular brightening of the circumstellar ring has begun. The supernova occurred in the Large Magellanic Cloud, a galaxy only 160,000 light years from Earth. The outburst was visible to the naked eye, and is the brightest known...

ESA -- Scientists have found that a star that exploded in 1979 is as bright today in X-ray light as it was when it was discovered years ago, a surprise finding because such objects usually fade significantly after only a few months. Using ESA's XMM-Newton space observatory, a team of astronomers has discovered that this supernova, called SN 1979C, shows no sign of fading. The scientists can document a unique history of the star, both before and after the explosion, by studying rings of light...

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. Nathan Smith, a Hubble Fellow and postdoctoral researcher at CU-Boulder's Center for Astrophysics and Space Astronomy, said the violent panorama is unfolding in the Carina Nebula, located in the southern Milky Way some...

Chandra -- Two scientists have discovered a distinctive shell of hot gas around the site of a distant supernova explosion by combining 150 hours of archived data collected by NASA's Chandra X-ray Observatory. This discovery is a significant step forward in solving a decades-old puzzle as to why some stellar explosions display shells and others do not. "The likely answer is that the explosion of every massive star sends a sonic boom rumbling through interstellar space," said Samar Safi-Harb...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
