Satellite Integral - Illustration - Artist's view of the European satellite INTEGRAL (International Gamma - Ray Astrophysics Laboratory) observing a black hole. Integral (International Gamma - Ray Astrophysics Laboratory) is the first space observatory that can simultaneously observe objects in gamma rays, X - rays, and visible light. Its main targets are violent explosions known as gamma - ray bursts, powerful phenomena such as supernova explosions, and regions in the Universe thought to contain black holes. Launched on 17 October 2002 (Proton launcher from Baikonur, Kazakhstan)

Andromede galaxy (M31) seen in X and infrared - Andromeda galaxy infrared and X - Ray composite - Andromede spiral galaxy seen in X-ray (blue) by the XMM - Newton space telescope and in infrared (orange) by the Herschel space telescope. This mosaic of the Andromeda spiral galaxy highlights explosive stars in its interior, and cooler, dusty stars forming in its many rings. The image is a combination of observations from the Herschel Space Observatory taken in infrared light (seen in orange hues), and the XMM - Newton telescope captured in X - rays (seen in blues). Herschel provides a detailed look at the cool clouds of star birth that line the galaxy's five concentric rings. Massive young stars are heating blankets of dust that surround them, causing them to glow in the longer - wavelength infrared light, known as far - infrared, that Herschel sees. In contrast, XMM - Newton is capturing what happens at the end of the lives of massive stars. It shows the high - energy X - rays that come

Centaurus A elliptical galaxy (NGC 5128) in Centaurus - Galaxy Centaurus A (NGC 5128) - The galaxy NGC 5128 is located about 13 million light years away from Earth in the southern constellation of Centaurus. A broad dark band crosses it in the middle, a probable vestige of a collision with a spiral galaxy. This Giant Galaxy is a powerful radio source known as Centaurus A. It is an active galaxy whose energy comes from a supermassive black hole. The green dot visible in the dust strip is a supernova, the supernova 1986g. It appears green because the red filter image that made this trichromy image was only taken a year after the event and the supernova had weakened. Image obtained from the 3.9m telescope of Siding Spring, Australia. Centaurus A is a most unusual galaxy. The circular, uniformly bright portion is composed of several thousand million stars, most of them old and yellowish. The galaxy is girded by a dense dust lane which obscures and reddens the light of stars behind it. Some

This filamentary material will eventually be recycled into building new generations of stars in the LMC.

Artist's impression of two neutron stars - the compact remnants of what were once massive stars - spiralling towards each other just before merging.

A couple of seconds after that, ESA's Integral and Nasa's Fermi satellites detected a burst of gamma rays, the luminous counterpart to the gravitational waves emitted by the cosmic clash.

Chandra and XMM - Newton observations of the red dwarf star Proxima Centauri have shown that its surface is in a state of turmoil. Flares, or explosive outbursts, occur almost continually. This behavior can be traced to Proxima Centauri's low mass, about a tenth that of the Sun. In the cores of low mass stars, nuclear fusion reactions that convert hydrogen to helium proceed very slowly, and create a turbulent, convective motion throughout their interiors. This motion stores up magnetic energy which is often released explosively in the star's upper atmosphere where it produces flares in X - rays and other forms of light. The same

Abell 2218 galaxy cluster in the Dragon - Gravitational lenses in the galaxy cluster Abell 2218 - The Abell 2218 galaxy cluster is located about 2 billion years ago - light from Earth in the constellation of the Dragon. It is so massive that its gravity curved and amplifies the light from other galaxies located behind it.

Crab Nebula seen in different wavelength - The Crab Nebula in multi wavelength: M1, the Crab Nebula, is the rest of a supernova that exploded on July 4, 1054. It is located about 6500 light years from Earth in the constellation Taurus. At the heart of this nebula is a pulsar. To obtain this photo, different observatories and telescopes combined their observations; the VLA provided the radio image (in red), the Spitzer telescope the infrared image (in yellow), the Hubble telescope for the visible part (here in green), XMM-Newton the ultraviolet image (in blue) and the Chandra telescope for X-ray data (purple). The pulsar is the bright spot in the center of the image. The unusual image was produced by combining data from telescopes spanning almost the entire electromagnetic spectrum, from radio waves to X-rays. The Karl G.

Planetary nebula NGC 6537 in Sagittarius - Hubble observations have revealed huge waves sculpted in the Red Spider nebula. This warm and windy planetary nebula harbours one of the hottest stars in the Universe and its powerful stellar winds generate waves 100 billion kilometers high - intimidating for even the bravest space surfers. The Red Spider Nebula, NGC 6537, is a striking 'butterfly' or bipolar (two - lobed) planetary nebula. Planetary nebulae are the glowing embers of ordinary stars, such as our Sun. At the end of their lives these stars expel most of their material into space, often forming a two - lobed structure as in the case of the Red Spider. These waves are driven by stellar winds radiating from the hot central star, much as a wind passing over a lake can generate waves on the water. The waves reach peaks 100 billion kilometers high and must have been produced by a powerful wind blowing with a speed of 2000 - 4500 kilometers per second (about 7 - 16 million km/hr). The w

The galaxy cluster, photographed by the Magellan telescope and the Hubble space telescope, appears in the background. By studying the mass of this cluster, astronomers were able to determine that most of this mass was concentrated not in the hot gas detected by Chandra but in the blue coloured areas here, suggesting the existence of dark matter. This composite image shows the galaxy cluster 1E 0657 - 556, also known as the “” bullet cluster.”” This cluster was formed after the collision of two large clusters of galaxies, the most energetic event known in the universe since the Big Bang.

The brightest source on this image is Sirius B, a white dwarf star whose surface, heated at a temperature of 25,000 degres, emits huge X-rays. The other point is Sirius A, the brightest star in the sky in visible light, but practically non-existent in this wavelength. An X - ray image of the Sirius star system located 8.6 light years from Earth. This image shows two sources and a spike - like pattern due to the support structure for the transmission grating. The bright source is Sirius B, a white dwarf star that has a surface temperature of about 25,000 degrees Celsius which produces very low energy X - rays. The dim source at the position of Sirius A, a normal star more than twice as massive as the Sun, may be due to ultraviolet radiation from Sirius A leaking through the filter on the detector.

Planetary nebula NGC 6543 in the Dragon - Planetary nebula NGC 6543 in Draco - Composite view of the planetary nebula NGC 6543 in the Dragon obtained by the Hubble space telescope and X-ray (blue) by the Chandra satellite. NGC 6543 is located about 3000 years of light from Earth. This composite of data from Nasa's Chandra X - ray Observatory and Hubble Space Telescope is a new look for NGC 6543, better known as the Cat's Eye nebula. This famous object is a so - called planetary nebula that represents a phase of stellar evolution that the Sun should experience several billion years from now. When a star like the Sun begins to run out of fuel, it becomes what is known as a red giant. In this phase, a star sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures seen with optical telescopes

The colors show different X - ray energies, with red, green, and blue representing low, medium and high energies, respectively. The image is cut off at the bottom because the southernmost region of the remnant fell outside the field of view of the detector. A shock wave produced by the expanding debris is outlined by the strikingly sharp blue circular arcs of twenty million degree Celsius gas seen on the outer rim. The stellar debris, which has a temperature of about ten million degrees and is visible only in X - rays, shows up as mottled yellow, green and red fingers of gas.
