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

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

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread ...

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, ...

Far beyond Neptune, in the frozen depths of the Kuiper Belt, many ancient objects oddly resemble giant snowmen made of ice and rock. For years, scientists wondered how these delicate two-lobed shapes ...

This gas cloud located 500 light years away from our solar system is about to become a planet.This process usually takes a few hundred million years, but what if we made it happen much quicker. And ...

NASA shared some new infrared images of the 3I/ATLAS interstellar comet this week, showing the visitor brightening up in a dramatic outburst while exiting a solar system. The images were taken by the ...

A team of scientists from around the world has created the first system that can predict when and where extremely powerful ...

Out in the Kuiper Belt, the massive doughnut of debris beyond Neptune, about one in 10 kilometer-scale objects have surprised ...

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 ...

For millions of years, a frozen wanderer drifted between the stars before slipping into our solar system as 3I/ATLAS—only the third known interstellar comet ever spotted. When scientists turned NASA’s ...
