The comet is the third object ever confirmed to have entered our cosmic neighborhood from elsewhere in the galaxy. Space ...

A team of researchers from the University of Zurich and the NCCR PlanetS is challenging our understanding of the solar system ...

Giant, dense structures have been discovered beneath the surface of Mars and they are leaving experts both mystified and excited. The first of these, confirmed by researchers in a fascinating paper, ...

The interstellar comet 3I/ATLAS is making its final pass, highly active after its Sun encounter. NASA and ESA release new ...

This list exemplifies the hard work in science over this past year, not simply in the lab but where it matters.

Zanskar uses AI to identify hidden geothermal systems—and claims it has found one that could fuel a power plant, the first ...

A new study reveals how shifting ice shells on icy moons can cause dramatic pressure changes, sometimes enough to boil their hidden oceans. The outer planets of our Solar System are accompanied by ...

Despite their liquid water and potential for habitability, these moons are very different environments from Earth. On Earth, ...

The outer planets of the Solar System are swarmed by ice-wrapped moons. Some of these, such as Saturn’s moon Enceladus, are known to have oceans of liquid water between the ice shell and the rocky ...

(THE CONVERSATION) When astronomers search for planets that could host liquid water on their surface, they start by looking at a star’s habitable zone. Water is a key ingredient for life, and on a ...

The Kuiper belt, a disc of icy rocks on the outermost edges of the solar system, seems to have more structure than we thought. In 2011, researchers found a cluster of objects there on similar orbits ...

"If our solar system is indeed moving this fast, we need to question fundamental assumptions about the large-scale structure of the universe." Astronomers have discovered that the solar system may be ...
