We Finally Know How Black Holes Produce the Brightest Light in the Universe

We Finally Know How Black Holes Produce the Brightest Light in the Universe

For something that emits no light that we can detect, black holes love to blanket themselves in radiation. In fact, some of the brightest light in the Universe comes from supermassive black holes. Well, not really black holes themselves; it is the material that surrounds them as they actively suck up large amounts of matter …

Scientists Discover Incoming Asteroid Just Hours Before It Impacts

Scientists Discover Incoming Asteroid Just Hours Before It Impacts

For only the sixth time in recorded history, astronomers have managed to spot an asteroid before it hits Earth. On November 19, 2022, nearly four hours before impact, the Catalina Sky Survey discovered an asteroid named 2022 WJ1 on an inbound trajectory. A network of telescopes and scientists sprang into action, calculating precisely when and …
