Saturn's largest moon, the smog-enshrouded Titan, could be the result of a dramatic merger between two other moons that ...

In a conventional system like our own, rocky planets such as Mercury, Venus, Earth, and Mars orbit closest to the host star. Farther out, gas giants ...

This hypothesis has the advantage of explaining why the rings have a lot of ice and little rock, in contrast to models where a moon strayed inside Saturn’s Roche limit and was pulled apart.

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

Scientists say an ultra-powerful neutrino once thought impossible may be explained by an exotic black hole model involving a so-called “dark charge.” ...

Astronomers using the James Webb Space Telescope (JWST) have discovered galaxies colliding in the early universe, revealing that cosmic structures are far more complicated than astronomers once ...

We go in depth on black holes: the strangest objects in the universe! Black holes are not just the strangest objects in the universe, they're the sharpest test we have of how reality actually works.

The pseudo-color images of JWST’s Quintet at redshift 6.71. a) The pseudocolor image created from NIRCam F115W (blue), F150W (green), and F200W (red) images. The five emission line galaxies in JWST’s ...

A report filed by SpaceX with the US Federal Communications Commission (FCC) in late December reveals some startling information – including that its Starlink satellites had to perform about 300,000 ...

This artist’s concept shows the violent collision of two massive objects in orbit around the star Fomalhaut. “Spotting a new light source in the dust belt around a star was surprising. We did not ...

In 1978, NASA researcher Donald Kessler and his colleagues published a paper titled “Collision frequency of artificial satellites: The creation of a debris belt.” The paper laid down a grim warning: a ...

NASA’s Hubble Space Telescope got a rare look at the aftermath of two cosmic collisions — and helped scientists solve a decades-old mystery. Many years ago, scientists saw a dense, bright spot near a ...
