'Pacman' Nebula Gets Some Teeth
2011-10-27 12:24:20

To visible-light telescopes, this star-forming cloud appears to be chomping through the cosmos, earning it the nickname the "Pacman" nebula, like the famous Pac-Man video game that debuted in 1980. When viewed in infrared light by NASA's Wide-field Infrared Survey Explorer, or WISE, the Pacman takes on a new appearance. In place of its typical, triangle-shaped mouth is a new set of lower, sharp-looking teeth. The Pacman is located at the top of the picture, taking a bite in the direction of...

Legend has it that a noon-day star appeared in 1630 at the birth of King Charles II, who later was restored to the English monarchy after his father was executed, reports AFP. Edward Matthew, an English writer, described the event as "The Most Glorious Star"¦ shining most brightly in a Miraculous manner in the Face of the Sun," in 1661. He writes in a pamphlet, "Never any Starre [had] appeared before at the birth of any (the Highest humane Hero) except our Savior." Historians have...

Two new efforts have taken a famous supernova remnant from the static to the dynamic. A new movie of data from NASA's Chandra X-ray Observatory shows changes in time never seen before in this type of object. A separate team will also release a dramatic three-dimensional visualization of the same remnant. Nearly ten years ago, Chandra's "First Light" image of Cassiopeia A (Cas A) revealed previously unseen structures and detail. Now, after eight years of observation, scientists have been able...

Astronomers have unearthed secrets from the grave of a star that blasted apart in a supernova explosion long ago. By decoding ghostly echoes of light traveling away from the remains of a supernova called Cassiopeia A, the scientists have pieced together what the star looked like in life, and ultimately how it met its demise. The discovery, made using primarily NASA's Spitzer Space Telescope and Japan's Subaru telescope on Mauna Kea in Hawaii, represents the first time astronomers have been...

Astronomers using NASA's infrared Spitzer Space Telescope have discovered that an exploded star, named Cassiopeia A, blew up in a somewhat orderly fashion, retaining much of its original onion-like layering. "Spitzer has essentially found key missing pieces of the Cassiopeia A puzzle," said Jessica Ennis of the University of Minnesota, Minneapolis, lead author of a paper to appear in the Nov. 20 issue of the Astrophysical Journal. "We've found new bits of the 'onion' layers that had not...

A new image taken with NASA's Hubble Space Telescope provides a detailed look at the tattered remains of a supernova explosion known as Cassiopeia A (Cas A). It is the youngest known remnant from a supernova explosion in the Milky Way. The new Hubble image shows the complex and intricate structure of the star's shattered fragments. The image is a composite made from 18 separate images taken in December 2004 using Hubble's Advanced Camera for Surveys (ACS), and it shows the Cas A remnant as a...

JPL -- An enormous light echo etched in the sky by a fitful dead star was spotted by the infrared eyes of NASA's Spitzer Space Telescope. The surprising finding indicates Cassiopeia A, the remnant of a star that died in a supernova explosion 325 years ago, is not resting peacefully. Instead, this dead star likely shot out at least one burst of energy as recently as 50 years ago. "We had thought the stellar remains inside Cassiopeia A were just fading away," said Dr. Oliver Krause,...

The IC 342/Maffei Group (also known as the IC 342 Group or the Maffei 1 Group) is the closest group of galaxies to the Local Group. The member galaxies are both concentrated around the two brightest galaxies of IC 342 and Maffei 1. The group can therefore be described as a binary group. Along with many others the group is located in the Virgo Supercluster.

Cassiopeia Constellation -- Cassiopeia is a northern constellation representing the legendary queen of Ethiopia Cassiopeia, who was the wife of Cepheus and the mother of Andromeda. It is one of the 88 modern constellations, and was also one of the 48 listed by Ptolemy. Notable features Five of the stars of Cassiopeia form a W shape, which is one of the most distinctive patterns in the northern sky. Since it is close to the north celestial pole, it remains in the sky all night long in...
