The XMM - Newton place scope has been really into dark and sullen stuff and nonsense lately . No , the x - beam observatory did n’t find its parents ’ sure-enough Black Sabbath albums — it detect the most massive galactic cluster on record book , a conglomerate of galaxy weighing more than 1,000 times as much as the Milky Way . The clustering ’s uttermost aloofness is a enigmatic paradox , or it might help test that the universe is full of mysterious dark energy . Last week , we told you abouttwo galactic cluster colliding , providing ocular ( and x - re ) evidence of the existence of dark matter . Dark energy is even more baffling , but astronomers who were take care at an entirely different cosmic object may have stumbled across a major clue . The large blue glow in the ikon ( taken with the Large Binocular Telescope at the Mt. Graham International Observatory to confirm XMM - Newton ’s discovery ) is a astronomical bunch with the tricky name 2XMM J083026 + 524133 . It ’s heavier than any other clustering , and it ’s farther from Earth than any other as well . In fact , it ’s double as far as the next farthest . Here ’s the mystery — really remote bunch should be very young , because it read their brightness so long to turn over us . Young bunch should n’t be big , because it take clock time for all those wandflower to pull together . A huge , distant cluster is seemingly inconceivable . That ’s where dark energy issue forth in . Dark push , to put it into very simple term , is a sort of anti - gravity force that actually push infinite apart and speed up the expansion of the universe . If it exists , that is . It is one potential explanation for 2XMM J083026 + 524133 ’s length . It might be an onetime cluster that seem more distant than it should be due to dark energy fueled expansion of blank space .
