For the first time, scientists detect molecule critical to life in interstellar space

The chemical is known as thiepine, or 2,5-cyclohexadiene-1-thione (C₆H₆S), a ring-shaped sulfur-bearing hydrocarbon produced in biochemical reactions. When examining the molecular cloud G+0.693–0.027, a star-forming...

A new cosmic map reveals how dark matter built the universe we live in

Scientists have created the most detailed map yet of dark matter—the mysterious substance that makes up most of the universe and quietly shapes everything...

A hidden dark matter sheet may be steering our cosmic neighborhood

Astronomers may have solved a long-standing mystery about how galaxies near the Milky Way move through space. New computer simulations suggest that our galaxy is...

How tiny Mars helps set Earth’s ice ages

Mars is only about half the size of Earth and has just one-tenth of our planet’s mass. Compared with giants like Jupiter, it seems far...

When a black hole ate a super-sized star: Inside the violent “whippet” explosion

Astronomers have witnessed an extraordinary cosmic catastrophe: a black hole tearing apart a massive star and devouring it piece by piece. The dramatic event, nicknamed...

Why the carbon in your body and the oxygen you breathe came from ancient...

Where did the carbon in our bodies and the oxygen we breathe come from? Astronomers have been asking this question for decades, and a new...

What Jupiter’s swirls and Saturn’s hexagon reveal about the planets’ hidden interiors

For years, spacecraft images have shown that the poles of Jupiter and Saturn are anything but calm. Each planet hosts giant atmospheric whirlpools called...

Astronomers discover a ‘dead’ galaxy that was choked by its own black hole

Astronomers have discovered one of the oldest “dead” galaxies ever seen—and its story is not one of sudden destruction, but of slow starvation. Using the...

NASA confirms thousands of massive, ancient volcanic eruptions on Mars

Scientists found evidence that a region of northern Mars called Arabia Terra experienced thousands of “super eruptions,” the biggest volcanic eruptions known, over a...

Scientists find the closest black holes to Earth in our cosmic backyard

Imagine having mysterious cosmic monsters right next door! Scientists say they might have found the closest black holes to Earth ever, and guess where they...

We might finally know how galaxies grow so large

Astronomers have spent decades trying to understand how galaxies grow so large. One piece of the puzzle is spheroids, also known as galactic bulges. Spiral...

Could life survive on Mars? Hardy lichens pass the test in new study

In a groundbreaking study, scientists have shown that certain types of lichens—organisms known for thriving in Earth's harshest environments—can survive in conditions similar to...

Where can we find a fifth force of nature?

We know of four fundamental forces of nature, with no signs of a fifth. But dark matter and dark energy make up over 90% of...
