The NASA observes the collision of two galaxies
The Chandra RontGentelescope spawn into the depths of space. Now it has taken a new spectacular picture that shows the wrong world of two merging galaxies.
Chandra we owe incredibly beautiful pictures of far away cosmic objects such as Cassiopeia A, Tycho-Supernova, the Moon Sichel or Cat eye fog (cf. Desktop Patterns: Image of the Year: 1999 to 2006). The space telescope circled since 1999 around the earth to throw a view of the air atmosphere to distant galaxies. It records ray radiation from high energy regions of the universe with a variety of scientific instruments – like the afterglow exploded stars.

But Chandra not only provides fantastic shots, but above all groundbreaking scientific knowledge about the nature of various formations and objects such as the dark rivers of black punches (cf.Gigantic deep hum), the nature of the ultra-dun gas veil between the galaxies (cf. Relocated galaxies recover), the sausing coexistence of double stars (cf. Unglassful dwarfsters in Flagranti Eachapt 20062), or the confirmation of the value of the Hubble Constant (cf. The cosmos expands unnecessary).
Now a group of scientists wanted to know about Diana Worrall by the British University of Bristol External exactly what is going on inside the Galaxy 3C442A, which is about 390 million light years away from us (cf. The Interaction Between Radio Lobes and Hot Gas In The Nearby Radio Galaxies 3C285 and 3C442A external). The combination of rontgen recordings of Chandra and radio waves of the Very Large Array of the National Science Foundation External clarified that it is not a galaxy, but two, which are there to unite one another. They have already brought an intimate approach behind, now they control them again.

But the combination of the findings from the two different observations brought much more new. According to the current state of astronomy, virtually all galaxies in their center seem a very massive black hole to accommodate, with millions of billion masses of the sun. In some galaxies, it becomes active by absorbing gas from its environment and a portion thereof as a plasma (consisting of protons, electrons and electromagnetic waves) with speeds out very close to the speed of light. These so-called relativistic exchanges each form a narrow gas jet, which slides out of a DUSE, and extends in some cases over the hundredfold expansion of the galaxy. These jets light brightly in the radio wave range (cf. Cosmic light pollution). They then anneal the gas radiating in the ray area.

But at the Galaxy 3C442A, this is very different. The heater gas (recognizable on the recordings as a ray radiation in blue) displaces the other gas, which lights up in the radio wave range (in orange on the picture of the VLA). This unusual dynamic is probably caused by the crash of the two galaxies (cf. Animation of various views – visually, in the ray and radio wave range – from 3C442A). This role exchange is amazing and, in the opinion of the researchers, is probably caused by the total heated atmosphere of the associated galaxies. The jets released in the radio wave range have lost their drive, they are no longer active and are now pushed to the side.
