The first known interstellar comet - 21/Borisov - probably came here from a red dwarf star, according to a new study of data from the Hubble Space Telescope.

Scientists just announced 2 new exciting updates about exoplanets. One is a potentially habitable world similar in size and temperature to Earth. The other is a possible new planet - possibly with rings - orbiting the closest star to our sun, Proxima Centauri.

On April 19, 2020, many in western Europe were stunned to spot a line of satellites crossing the night sky. They were the SpaceX Starlink satellites.

The NASA Curiosity mission team is keeping the rover moving and working on the surface of Mars while they #stayathome. Find out how they’re managing it.

NASA's WFIRST mission - an infrared space observatory planned for launch around 2025 - will use the fact that the gravity of distant objects warps spacetime, bending and focusing light, thereby revealing new worlds.

Fascinating video! Tour the International Space Station with ESA astronaut Luca Parmitano and NASA astronaut Drew Morgan. Shot in one take with two cameras strapped together.
