A red dwarf barely 40% the mass of our Sun is orbited by a gas giant nearly the size of Jupiter. TOI-5205b shouldn't exist according to planet formation theory — and when JWST peered at its atmosphere, the surprises kept coming.
Red dwarfs — small, dim, and utterly unremarkable — have been quietly swallowing their own planets. A May 2026 discovery used lithium as the smoking gun. The same thing may have happened in our own solar system.
Astronomers have discovered a super-Earth orbiting the red dwarf Ross 318, a mere 28 light-years from Earth. With six times our planet's mass, it sits inside the habitable zone where liquid water could exist — and hints of an atmosphere make it one of the most compelling nearby finds in years.
M-type dwarf stars — red dwarfs — make up more than 70% of all stars in the galaxy. They're small, long-lived, and surrounded by rocky planets. So why are they so hostile to life? SORABUMI breaks down the battle between stellar flares and planetary atmospheres.
When you look at a star's color, you're reading its temperature directly. Blue stars burn hot and die young; red stars simmer slowly for trillions of years. Here's how a star's color encodes its entire life story.
