It’s a happy day when astronomers figure out what’s up with an enormous space blob—and the answer doesn’t imply the immediate destruction of humanity.
Scientists have pinpointed the most ancient oxygen yet discovered in the universe. Spied by the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile, the oxygen is nestled in a galaxy 13.1 billion light-years from Earth. Called SXDF-NB1006-2, this galaxy is one of the oldest known.
Thirty million years ago in a galaxy not so far, far away, a star exploded. Three years ago, light from that explosion finally made it to Earth, where scientists watched the explosion unfold from start to finish.
Researchers scanning the skies just got a big surprise. They spotted a humongous galaxy orbiting our own, where none had been seen before. It appeared, seemingly, out of nowhere.
Astronomers have just discovered one of the biggest black holes ever. Even more surprising, though, is where they found it—and the strange reason it got so big.
An invisible cloud of gas is speeding toward our Milky Way galaxy at 700,000 miles per hour. But don’t worry: It will take about 30 million years to get here.
