Telescope "Chandra" captures the gas cloud of two merging galaxies


03/05/2013

Astronomers working with the telescope "Chandra", managed to shoot X-ray radiation from cosmic clouds of gas that surrounds the two merging spiral galaxy NGC 6240. The resulting image, with a detailed description was published a few days ago on the site of the observatory.

The object NGC 6240, located in the constellation Ophiuchus represents the two merging galaxies, each of which is in the central part there is a supermassive black hole. Star clusters are comparable in size to the Milky Way. From our planet, this buildup removed 320 million light years away.

The length of the wrapping of the galaxy halo strongly heated gas, captured "Chandra", is 300,000 light-years, while its mass reaches about 10 billion solar masses. Meanwhile, X-ray radiation reflects halo extremely high temperature gas - about 7 millions of degrees.

In the future, these two spiral galaxies NGC 6240, according to the astronomers, certainly will merge into a single star cluster elliptical. However, not all galactic collisions end in this way - is that clusters pass through each other. This happens almost always, but the interaction of galaxies leads to a perturbation of the interstellar gas, which ultimately contributes to the rapid formation of new stars.

Recall that the image of NGC 6240 was obtained by the space telescope "Chandra", designed for tracking objects in space X-rays. Most recently, he helped the scientists to get a very clear image of the supernova SN 1006, more precisely, its residue. For information about the outbreak of the supernova in 1006 AD. e. were recorded by Chinese, European and Arab astronomers in the historical sources.
