General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Recent research suggests that Saturn's bright rings and its largest moon, Titan, may have both originated in collisions among its moons. While Cassini's 13-year mission expanded our understanding of ...

Astronomers may finally understand why planets orbiting two suns, the real-world equivalents of the "Star Wars" planet Tatooine, are so scarce in our galaxy — and it has to do with general relativity.

New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems ...

A single scenario could explain some of the odd features of Saturn's cosmic neighborhood. A project that set out to seek the origin of the planet's rings and why Titan’s orbit is expanding may have ...

For decades, scientists have theorized that the Milky Way Galaxy’s supermassive black hole, known as Sagittarius A* (Sgr A*), ...

Saturn’s largest moon, Titan, may have been born of the collision of two smaller moons, according to new research.

Petroglyphs on sandstone at a national park in Chad bear witness to wildlife that once roamed the area before the continent’s ...

A study exploring the mechanisms behind why cognitive performance improves in response to exercise, has found that dopamine plays a key role. A study exploring the mechanisms behind why cognitive ...

The roots of Russia's invasion of Ukraine go back decades and run deep. The current conflict is more than one country fighting to take over another; it is — in the words of one U.S. official — a shift ...

Mystery solved! Here's what TL;DR means and why you keep seeing it online. It can be hard to stay current with the latest slang. Language (and internet culture) continues to evolve, resulting in an ...
