The universe hosts a myriad of star types, including supergiants, giants, main sequence, red dwarfs, brown dwarfs, white dwarfs, and neutron stars.…

"Unlike exoplanets, free-floating brown dwarfs are completely independent celestial objects that will fade into eternity alone."

The stars in our galaxy come in a beautiful assortment of colors. We see supergiants such as Betelgeuse that have a warm red glow, and others like Rigel that shine […]

Astronomers have discovered the first evidence that tiny red dwarf stars can devour their own planets.

We know that stars can engulf planets because stars that swell up to become red giants overwhelm any close-in planets. The Sun will do this to Venus, Mercury, and possibly Earth in a few billion years.…

Brown dwarfs are notoriously difficult to find. These “failed stars” aren’t big enough to sustain nuclear fusion, and therefore aren’t as bright as more traditional main sequence stars.…

Kepler and TESS showed us that there's a radius gap in the exoplanet population. There are very few planets between 1.5 and 2 Earth radii, according to the data. But new research shows that the gap may not be as significant as thought.

A new paper from NASA’s Backyard Worlds: Planet 9 project announces that volunteers have essentially doubled the number of known brown dwarfs, with over 3,000 new discoveries made over the past 10 years since the project began.…
