Astronomers using China's Einstein Probe telescope have observed a powerful X-ray flash that matches the predicted signature of a 'dirty fireball,' a theorized explosion from a dying massive star. The event, labeled EP241113a, originated from a galaxy about 9 billion light years away. This detection could reveal new details about how massive stars end their lives.

A comet discovered earlier this year will reach its closest point to Earth this fall. Named after the observatory where it was spotted, Comet Lemmon offers a rare viewing opportunity before it vanishes for over a millennium. Astronomers first detected it in January at the Mt. Lemmon Observatory in Arizona.
