Black holes are supposed to be dark—that's literally in the name. But astronomers are witnessing something that defies expectations: a supermassive black hole that's been steadily brightening over years and is now among the most luminous events ever observed in the cosmos. The mystery? Nobody knows why.
University of Michigan astronomers have made a groundbreaking discovery that's reshaping our understanding of the Milky Way's structure. By identifying 87 stellar streams—rivers of stars flowing through our galaxy—these researchers are unveiling the cosmic architecture we've been living in all along.
Deep beneath the Earth's surface, scientists are building extraordinary detectors designed to capture the ghostly echoes of stars that died billions of years before our planet even existed. These cosmic messengers could revolutionize our understanding of the universe's earliest moments.
