Video: Eta Carinae may explode in a supernova definitely in the next thousand years. Its luminosity is about four million times that of the sun, and its estimated weight is about 100 to 150 solar masses. This star is one of the most massive stars being discovered. video Zooming Into WR 22 & Carina Nebula

Carina in X-ray
The Carina Nebula is home to over 14 000 stars. This region of star formation in the Carina Nebula was analyzed by the Chandra X-Ray Observatory has detected more than 14 000 stars. The view from Chandra X-Ray provides strong evidence of massive stars that have self-destructed in the vicinity of this region. First, there is a deficit of observed bright X-ray sources in the area known as Trumpler 15, which suggests that some massive stars in this group have already been destroyed by supernova explosions. Trumpler 15 is located in the northern part of the image and is one of ten star clusters in the Carina Nebula. Astronomers have detected six neutron stars. These are dense cores of stars, often left behind after their supernova explosion. This is further evidence of supernova activity in the hull. Previous observations had detected only a neutron star in Carina. X-rays are produced in the cosmos when matter is heated to millions of degrees. These temperatures occur where there are high magnetic fields, or extremely serious.
X-ray telescope can detect the hot gases from the explosion of a star or X-rays from matter swirling on the edge of a black hole. The Chandra X-ray Observatory, which was launched by Space Shuttle Columbia in 1999 to better define the hot and turbulent regions of space. This greater clarity, in another frequency range, X-rays, may help scientists answer fundamental questions about the origin, evolution and destiny of the Universe.
Imaage: Carina Nebula seen in the X-ray In this picture, X-rays of low energy, are red, medium energy X-rays are green, and those of higher energy are blue. Chandra has a large field of 1.4 degrees, consisting of a mosaic of 22 individual scores. Overall, this picture represents an observation time of 1.2 million seconds, nearly two weeks. Much of the data in this wavelength was used in compounds of images with the observations in the infrared by the Spitzer Space Telescope in the visible and with the VLT.
