Far off into the dark sky , a satellite find out something unexpected . A aim that looks like it could be for astronomic archery , accomplished with a black hole bullseye . The system photographed is called V404 Cygni , which consists of a dynamic couple of stellar objects : a black hollow and a Sun - similar star . Together , the binary pair produce this heavenly target .
The leading social organisation is the upshot of a black mess eruption so brawny that it skipped the low - energy , visible spectrum of light and emitted high - vitality X - electron beam lighter . Oddly , the black hole appears to have emitted three rather trenchant rings of hug drug - rays , but the true statement is actually quite dissimilar . The beam of light are all from the same source .
You might think of black holes as being sky " sinkholes " that only suck matter in , as even light ca n’t escape their gravitative clutches . So how could go - ray escape this one ’s grasp ?
The reply is in the accumulation disk around the fateful hole . The bootleg hollow is in a binary organization with its Sun - like star and as they circulate each other in their celestial dance , the black hole ’s sinewy gravitative attraction at times draw up some of the genius ’s outer layers of dust and gas .
This stolen star affair swirls around the black hole in an accretion disk before being sucked into it . As the matter swirls around the saucer , it gravel faster and creates rubbing against the other detritus particles , make the magnetic disk to heat up . finally , the dust becomes so red-hot that it releases some of its energy in a spectacular X - beam burst .
base on the gif , you might think that the accretion disc releases three speedy - fire X - ray bursts . Astrophysicists , however , think that there ’s a mere possibility . A detritus cloud between the black maw and the artificial satellite that saw it would deform the X - ray of light burst , refocus some of the light that was travel to miss the photographing satellite back towards it . This misrepresented beam of twinkle seem , from Earth , to be an entirely separate ring from the original X - light beam burst .

Since there are three doughnut , there must be three cloud of dust between us and the black-market jam . The largest ring is estimated to be roughly a third of the diameter of the Moon .
These images of cosmic tintinnabulation are some of the best examples of diffract ray forming rings ever taken . They were snap by NASA’sSwift satellite , which specialise in photographing high-pitched - energy wavelengths of light like ex - rays and gamma - ray . " The flexible preparation of Swift observations has given us the best dust - scattered Adam - ray mob mental image ever seen , " Andrew Beardmore , from theUniversity of Leicester , tell . " With these observation we can make a detailed study of the commonly invisible interstellar dust in the commission of this black hole . "
