A South Dakota-based instrument built to detect theoretical dark matter particles has sensed a particle interaction that’s difficult to explain with known phenomena. But more data is needed to confirm that the strange substance—which scientists have never directly observed—is, indeed, the culprit

The speedster travels at up to 56 million miles per hour, or about 8 percent the speed of light. It also gets very close to the supermassive black hole at the center of the Milky Way

The galaxy’s light took about 12.5 billion years to reach the James Webb Space Telescope, meaning the instrument saw the black holes a little more than one billion years after the Big Bang. Two of the black holes seemed on track to merge, illustrating how the objects grow
