Scientists' best explanation for how planets form is called the core accretion theory. The birth of a planetary system begins ...

A small red dwarf star is challenging our knowledge of how planets form by coexisting with a massive exoplanet, much like a ...

Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star.

The host star, TOI-6894, is a red dwarf with only 20% the mass of the Sun, typical of the most common stars in our galaxy.

Giant planets are not rare per se — after all, we have four in our own solar system. Such large worlds are, however, rarely ...

Scientists have discovered a giant planet called TOI-6894b, orbiting a star that should be far too small to have formed it.

It had not been thought possible that such tiny, weak stars could provide the conditions needed to form and host huge planets.

A small red dwarf star, TOI-6894, is defying astronomers' expectations by having a gas giant planet in its orbit.

With its low density and unusually cool, methane-rich atmosphere, this planet offers a rare window into giant planet formation around small stars.

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun. Like many small stars ...

A possible new dwarf planet has been discovered at the edge of our solar system, so far-flung that it takes around 25,000 ...
