Antarctica plays a crucial role in Earth's climate system by reflecting solar radiation back into space. The large white ice surfaces and clouds play a decisive role in this process. However, how ...

There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on ...

In the distant reaches of the solar system are many icy objects that resemble snowmen. Now, a new study reveals the simple ...

A new paper in Monthly Notices of the Royal Astronomical Society argues the simplest answer may work: contact binaries like Arrokoth can form directly during the gravitational collapse of a dense ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form. Reading time 3 minutes Astronomers have discovered a star system that’s out of ...

We know that our Solar System is not the blueprint for all planetary systems out there. There are gas giant planets orbiting closer to their stars than Mercury, and rocky worlds much larger than Earth ...

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust surrounding the early Sun. Once they were large enough, they attracted large ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

For decades, scientists have believed that planetary systems typically form with rocky planets close to their star and gas-rich planets farther away. This discovery questions their knowledge.

It might not look like much, but a star system shouldn’t look like this (Picture: European Space Agency) Scientists have discovered something that they previously thought wasn’t possible – an ‘inside ...
