These sodium atoms are part of the debris kicked up from the moon’s surface, mostly by micrometeorites, two new studies conclude.
Eclipses are one of nature’s most awesome spectacles, and scientists have learned a lot by observing them and related celestial alignments — occultations and transits.
A machine heats iron atoms to temperatures that match the interior of the sun. This has helped solve a solar mystery.
Groundbreaking research in astronomy landed four high school seniors spots as finalists in the 2014 Intel Science Talent Search.
