NASA's James Webb Space Telescope has spotted a young star flinging heat-formed crystals outward on a cosmic conveyor belt, offering a new clue to how comets evolve.

Sometimes astronomers don't need giant telescopes to observe the wonders of the cosmos; they just need to look up at the night sky.

Exhaust from lunar landers drifts across the moon and contaminates ultra-cold polar craters that are rich in ancient ice and organic clues, a new study reports.

"These results from the Dark Energy Survey shine new light on our understanding of the universe and its expansion."

Helping young people tap into their excitement about the night sky helps them build confidence and opens career pathways they may not have considered before.

"Stars like the sun don’t just stop shining for no reason."

The findings are a big clue as to why the far and near hemispheres of the moon look so different.

"Most excitingly, this new idea addresses one of the longstanding habitability problems on Europa and is a good sign for the prospects of extraterrestrial life in its ocean."

"It is exciting to think that Little Red Dots may represent the first direct observational evidence of the birth of the most massive black holes in the universe."
