An analysis of seismic waves propagating through Mars finds evidence that the planet has a small, solid inner core, which challenges existing planetary models. Read the paper: Seismic detection of a ...

A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole with a "dark charge." If true, this theory could lead to a definitive catalog ...

Astronomers have uncovered a massive hidden planet and a rare “failed star” by combining ultra-precise space data with some of the sharpest ground-based images ever taken. Using the Subaru Telescope ...

Scientists have discovered a rogue planet roaming the Milky Way after combining observations from Earth and a space telescope. This rare dual perspective allowed them to weigh the planet and pinpoint ...

Peking University, January 2, 2026: A lucky alignment of space- and ground-based telescopes has enabled researchers to nail down the mass of a rogue planet for the first time. Unlike worlds in our ...

This artist’s impression shows Cha 1107-7626. Located about 620 light-years away, this rogue planet is about 5-10 times more massive than Jupiter and doesn’t orbit a star. It is eating up material ...

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets seem to have been knocked out of their orbits, floating through space free ...

An international team of astronomers, co-led by researchers at the University of Galway, has made the unexpected discovery of a new planet. Detected at an early stage of formation around a young ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...
