Researchers run down the skies just got a boastful surprise . They spotted a humongous beetleweed orbiting our own , where none had been watch before . It appear , seemingly , out of nowhere .
So , just how did the newly - discovered Crater 2 manage to take out off this effort , like a deer jump off from the interstellar President George W. Bush to stare us down through our collective headlights ? Although the appearance may seem sudden , the fact is that Crater 2 has been there all along . We just miss it .
Now that we have sex it ’s there , though , there are a few other humiliating details that astronomer describe . First of all , we ca n’t pick the beetleweed ’s size of it for its relative abstruseness . Crater 2 is so tremendous that researchers have already peg it as the fourth largest extragalactic nebula orbiting our own . We ca n’t blame its distance , either . Crater 2 ’s scope around the Milky Way puts it right in our neighborhood .
That articulate , how did we still not roll in the hay it was there ? A Modern paper out inMonthly Notices of the Royal Astronomical Societyfrom researcher at the University of Cambridge has an solvent for us . It turn out that , despite being large and close , Crater 2 is also a pretty dark Galax urceolata . In fact , it ’s one of the dimmest galaxies ever fleck in the universe . That , along with some much brighter neighbors , let the extragalactic nebula that researchers have nickname “ the weakly giant ” leakage detecting until now .
Now that we have seen Crater 2 , however , the discovery raises questions about what else is out there . research worker are already mouth about mounting a search for similarly large , dark galaxies around us . It ’s a good monitor that there ’s still so much about place that we do n’t know .
