Red dwarf stars, also known as M-dwarfs, dominate the Milky Way's stellar population. They can last for 100 billion years…
Could Earth Life Survive on a Red Dwarf Planet?
Even though exoplanet science has advanced significantly in the last decade or two, we're still in an unfortunate situation. Scientists…
GJ 367b is Another Dead World Orbiting a Red Dwarf
Red dwarf exoplanet habitability is a hot topic in space science. These small dim stars host lots of exoplanets, including…
Hubble Succeeds Where TESS Couldn’t: It Measured the Nearest Transiting Earth-Sized Planet
Twenty-two light-years away, a rocky world orbits a red dwarf. It's called LTT 1445Ac, and NASA's Transiting Exoplanet Survey Satellite…
Do Red Dwarfs or Sunlike Stars Have More Earth-Sized Worlds?
Earth is our only example of a habitable planet, so it makes sense to search for Earth-size worlds when we're…
Astronomers are Watching a Planet Get its Atmosphere Blasted Away into Space
What do you get when a hot young world orbits a wildly unstable young red dwarf? For AU Microsopii b,…
Are Planets Tidally Locked to Red Dwarfs Habitable? It’s Complicated
Astronomers are keenly interested in red dwarfs and the planets that orbit them. Up to 85% of the stars in…
Two New Rocky Planets Discovered Close to the Solar System
TESS has struck paydirt again. NASA's planet-hunting spacecraft has found two new super-Earths orbiting a star only 33 light-years away.…
It Turns out, We Have a Very Well-Behaved Star
Should we thank our well-behaved Sun for our comfy home on Earth? Some stars behave poorly. They're unruly and emit…
