Scientists exploring Mars have uncovered strong new evidence that the Red Planet once had wave-washed beaches and long-lasting water activity, making it an even...

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...

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...

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...

When the rover now named Perseverance landed in Jezero crater in early 2021, scientists already knew they had picked an interesting place to scope...

Astronomers have discovered the largest sulfur-containing molecule ever seen in space, offering new clues about how the chemical ingredients of life may form long...

One of astronomy’s biggest mysteries has long puzzled scientists: how did black holes grow so enormous so quickly after the universe was born? New research...

Astronomers have discovered a vast cloud filled with vaporized metals and powerful winds orbiting a mysterious object far from its host star. The finding offers...

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...

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...

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...

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 have reported a second, super-sized moon orbiting a Jupiter-sized planet beyond our solar system. If confirmed, the sighting could mean that exomoons are as...

NASA’s Spitzer Space Telescope has provided astronomers with fascinating images that show how the supermassive black hole at the center of the Andromeda galaxy,...

Six or seven billion years ago, most stars formed in super star clusters. That type of star formation has largely died out now. Astronomers know...

How did everything begin? It's a question that humans have pondered for thousands of years. Over the last century or so, science has homed in...

As weird as it might sound, black holes appear to be holograms. In the 1980’s physicist Jacob Bekenstein was able to calculate exactly how much...
