Rogue planets wander the galaxy all alone
Some planets don’t orbit stars. They were kicked into space long ago. The newest, smallest one found is only about as massive as Earth.

Meet ‘Pi’ — a new Earth-sized planet
Searching through data from NASA’s K2 Mission, researchers found a new planet. Some call it K2-315b, others smile and refer to it as “Pi Earth.”

2020 Physics Nobel goes for delving into black holes
Although Einstein’s general theory of relative suggested black holes might exist, this year’s winner’s helped show they actually are out there.

Strange but true: White dwarfs shrink as they gain mass
Telescope observations of thousands of these stars now confirm a decades-old theory on how their masses relate to their waistline.

A weird cousin of our solar system is caught on camera
New photo reveals a cousin to our solar system. It’s star has a mass similar to the sun’s and is orbited by two gas giant planets.

Could ripples in spacetime point to wormholes?
A new calculation reveals that strange gravitational waves detected by LIGO and Virgo could see if a black hole were falling into a hypothetical tunnel in spacetime.

Milky Way’s tidal forces are shredding a nearby star cluster
The nearest star cluster is being pulled apart, due largely to the tidal forces of our galaxy, the Milky Way. Bye bye, Hyades!

Explainer: Stars and their families
Most pinpoints that light the night sky are raging infernos we call stars. As adults, many will create new elements that they later cast off into the cosmos.
