As Chile and Argentina witnessed the total solar eclipse on Dec. 14, 2020, unbeknownst to skywatchers, a little tiny speck was flying past the Sun — a recently discovered comet.

This comet was first spotted in satellite data by Thai amateur astronomer Worachate Boonplod on the NASA-funded Sung...

New research has found that by studying all three ‘flavors’ involved in a supernova, they’ve unlocked more clues as to how and why stars die. Any Neapolitan ice cream lover knows three flavors are better than one. New research from Northwestern University has found that by studying all three “flavors” involved in a supernova, they’ve unlocked more clues as to how and why stars die.

Scientists look at neutrinos (subatomic particles) for critical information about supernova explosions. While previous research identified three “flavors” of neutrinos, many researchers continued to simplify studies on the topic by studying “vanilla” while ignoring “chocolate” and “strawberry.”

By including all three flavors in the study, Northwestern researchers have developed a deeper knowledge of d...

How stars form in galaxies remains a major open question in astrophysics. A new study sheds new light on this topic with the help of a data-driven re-analysis of observational measurements. The star-formation activity of typical, nearby galaxies is found to scale proportionally with the amount of gas present in these galaxies. This points to the net gas supply from cosmic distances as the main driver of galactic star formation.

Stars are born in dense clouds of molecular hydrogen gas that permeates interstellar space of most galaxies...

Mineralogy points to large, water-rich parent asteroid for carbonaceous chondrite meteorite. A Southwest Research Institute-led team of scientists has identified a potentially new meteorite parent asteroid by studying a small shard of a meteorite that arrived on Earth a dozen years ago...
