Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

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

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, ...

The planetary system, located 120 light-years away, features four worlds orbiting a red dwarf star and challenges classical formation schemes.

When NASA’s twin Voyager probes left Earth in 1977, they carried computers weaker than a hand calculator and a modest goal of touring the outer planets. No one seriously expected them to redraw the ...

Discovery: On July 2, 2025, astronomers confirmed Comet 3I/ATLAS, marking only the third interstellar object (ISO) ever detected passing through our Solar System, after 1I/ʻOumuamua (2017) and ...

In the cold, distant reaches of the Solar System, far beyond Pluto, astronomers have just identified what could be a new dwarf planet. It's called 2017 OF 201, a rock that appears to be some 700 ...

The solar system does not end neatly at Neptune’s orbit. This episode reveals the vast, invisible structure of icy debris beyond the known planets, shaped by gravity and time. From scattered objects ...

After studying thousands of computer simulations of the solar system, researchers at Rice University and the Planetary Science Institute think there’s a 40% chance an elusive “Planet Nine” or “Planet ...

Scientists from UNSW Sydney have located a potential new exoplanet – a planet that orbits a star outside of our solar system – using a technique known as ‘transit timing variation’. In research ...

In an incredible breakthrough, a team of international astronomers have for the first time ever witnessed the birth of a planetary system beyond Earth's sun that could one day resemble our own. The ...

The system, observed using the European Space Agency's Cheops space telescope, consists of four planets — two rocky and two ...
