The Hubble Space Telescope has made detailed observations or debris cloud remnant of an ancient supernova.
The space telescope "Hubble" Astronomers have a new image of the globular cluster NGC 1846, located at a distance of 160 000 light years from Earth in the periphery of the satellite of our Galaxy, the dwarf galaxy the Large Magellanic Cloud. Press release published on the website telescope.
February 23, 1987 in our neighboring galaxy – the Large Magellanic Cloud – broke a supernova, which has become extremely important for astronomers, because it was the first, they, armed with modern astronomical instruments, could be studied in detail. And the star gave evidence of a series of predictions. Simultaneously with the optical flare special detectors installed in Japan and in Ohio (USA), recorded neutrino flux – the elementary particles produced at very high temperatures during the collapse of the stellar core and easily penetrate its shell.
In addition to the spiral and elliptical galaxies, there is a third type, irregular galaxies. As their name implies, they do not fall into one of two major categories, numbering together 90% of all known galaxies. Irregular galaxies do not have any drive, peculiar spiral systems or uniformity of structure characteristic of elliptical galaxies.
Super massive stars end their way of monumental explosion of a supernova. But when the most massive of these monsters die, theory predicts that they may not have time to explode – their massive core collapses in on itself. The explosion is so fast that all the material, as well as born-light photons, are absorbed immediately into the newborn black hole.
Astronomers can boast of yet another significant finding. This time they came on the heels of two star clusters, each of which is a massive star. Opening in second undermined earlier accepted the hypothetical limit of many cosmic giants. Mass of one of the found film stars at birth exceeded that of the Sun in 150 masses and was about 300 people. With the opening of the cluster space monsters, researchers can calculate the limit of many movie stars.
Russian astronomers using the Large Telescope Alt-azimuthal (BTA) have found this space a rarity – a star that belongs to a type of so-called bright blue variables. Today, we know no more than two dozen such stars. The fact that the life of their relatively small – no more than two million years.
