Debris from the collision could have formed another moon of Saturn called Hyperion, and affected the tilt of Saturn itself.

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 ...

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

Space around the Sun contains far more than planets. Scattered through it are smaller bodies made of rock, metal, ice and ...

In 2023, NASA’s OSIRIS-REx spacecraft collected samples of 4.6-billion-year-old rocks from an asteroid called Bennu and ...

As Australia’s renewable sector matures, the coupling of solar and storage is emerging as the dominant paradigm for ...

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...

Astronomers have found a compact solar system whose planets line up in a way that, according to current models, should not be possible. Around the small star LHS 1903, a dense rocky world orbits on ...

Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

Since the 1990s, astronomers have found a handful of other dwarf planets in the belt, such as Eris and Sedna, along with ...

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.
