Smithsonian researchers analyzed fragments of the near-Earth asteroid and discovered water-rich clays that hint at a distant ...

Astronomers have discovered a brand new type of planet outside our solar system that, even in its infancy, is already bigger ...

Earth is so far the only known planet on which life exists—with liquid water and a stable atmosphere. However, the conditions were not conducive to life when it formed. The gas-dust cloud from which ...

New models suggest that Ceres, the asteroid belt's largest object, once had a radioactive core that could have sustained life in the dwarf planet's hidden subsurface ocean billions of years ago.

A team of astronomers at the University of Arizona played an integral role in uncovering a baby planet with a pretty cute name: WISPIT 2b.

But in reality, it may be the beginning of a new phase of life for all the objects living in the solar system. When stars like the Sun die, they go through a phase of rapid expansion called the Red ...

Any quakes, or even rumbles from meteorite impacts, propagate outward from their point of origin, bouncing around inside a planet or moon or star before stilling to quietness. The way they travel ...

The Very Large Telescope view on the left shows the rings in the protoplanetary disk and the planet in yellow. Views from the Magellan Telescope in Chile and the Large Binocular Telescope in Arizona ...

Locked beneath a single-plate crust, Mars' mantle holds a frozen record of the red planet's primordial past, according to a new study of Martian ...

Our solar system's latest and only third known interstellar visitor is becoming more fascinating by the minute. Spotted in early July, the object, dubbed 3I/ATLAS, is believed to be a comet. It's ...

The planet is actively accreting material while carving a channel through the protoplanetary disc of gas and dust surrounding its host star, WISPIT 2. This marks the first confirmed discovery of a ...
