Nice Mosaics photos

Check out these mosaics images:

New Vista of Milky Way Center Unveiled: A 400 by 900 light-year mosaic of images located about 26,000 light years from Earth in the constellation Sagittarius.

Description: This Chandra image exposes a wealth of exotic objects and high-energy features at the center of our galaxy, the Milky Way. In this new and deep image from Chandra, red represents lower-energy X-rays, green shows the medium range, and blue indicates the higher-energy X-rays. Hundreds of small dots show emission from material around black holes, neutron stars and white dwarfs. A supermassive black hole — some four million times more massive the Sun — resides within the bright, blue-white region on the right. The diffuse X-ray light comes from gas heated to millions of degrees by outflows from the supermassive black hole, winds from giant stars, and stellar explosions.

Creator/Photographer: Chandra X-ray Observatory

NASA’s Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date. The mirrors on Chandra are the largest, most precisely shaped and aligned, and smoothest mirrors ever constructed. Chandra is helping scientists better understand the hot, turbulent regions of space and answer fundamental questions about origin, evolution, and destiny of the Universe. The images Chandra makes are twenty-five times sharper than the best previous X-ray telescope. NASA’s Marshall Space Flight Center in Huntsville, Ala., manages the Chandra program for NASA’s Science Mission Directorate in Washington. The Smithsonian Astrophysical Observatory controls Chandra science and flight operations from the Chandra X-ray Center in Cambridge, Massachusetts.

A nearby galaxy cluster about 65 million light years from Earth.

Description: Chandra’s mosaic of images of the Fornax cluster reveals that the vast cloud of ten-million-degree Celsius gas in the core of the cluster has a swept-back cometary shape that extends for more than half a million light years. This geometry suggests that the hot gas cloud is moving through a larger, but less dense cloud of gas that creates an intergalactic headwind. The core motion, combined with optical observations of the motion of a group of galaxies falling toward the core, indicates that the cluster lies along a large, unseen, filamentary structure composed mostly of dark matter. Most galaxies, gas, and dark matter in the universe are thought to be concentrated in such filaments, and galaxy clusters are thought to form where the filaments intersect.
