The American astronomers found out why dark gamma-vspleski is not visible in an optical range. Gamma-vspleski are one of the most enigmatic objects in modern astronomy. It is considered that greater part from them is the result of supervision of radiation
jet of matter, arising up during an explosion sverkhnovoy. Within the framework of work astronomers studied gamma-vspleski, discovered by an orbital telescope NASA Swift. They looked after the found flashes in an optical range through the telescope of Palomarskoy of observatory, located in California. They set as a result, that
14 from 29 gettings into account gamma-vspleskov were dark.Subsequent supervisions through a telescope Keck on the Hawaiian islands, however, rotined that not all flashes had been absolutely nevidimy. In three cases there was weak luminescence in an optical range, and
in other 11 the location of flashes on sky coincided with the location of the known galaxies. From astronomers concluded here, that these flashes are not visible in an optical range because light from them is blocked by the dense accumulations of dust in galaxies or around
stars.About it reports New Scientist, and the results scientists reported on convention of the American astronomic company.It was considered before appearance of work of the American scientists, that similar gamma-vspleski is remote from us on considerable distance – more than 12,9 milliards
light years. From expansion of Universe light, moving to Earth, is moved in red party of spectrum (so urgent redshift). Because distance to the flash is very great, then, reaching to our planet, all radiation appears moved in a red area
outside a visible range.- are one of the most enigmatic objects in modern astronomy. It is considered that greater part from them is the result of supervision of radiation of jet of matter, arising up during an explosion sverkhnovoy. Quite
recently astronomers succeeded to discover unusual dim sverkhnovuyu, the characteristic lines of hydrogen absented in the spectrum of radiation of which. Researchers suppose that similar sverkhnovye can carry responsibility for so urgent long gamma-vspleski,
