The James Webb telescope has made another stunning discovery -- this time of a massive planet that could potentially sustain life, according to multiple space agencies. Astronomers have captured "compelling evidence" of a planet with a mass about 100 times ...

Unusual rocks discovered on Mars contain the most tantalising evidence yet of potential past life on the Red Planet. The mudstones, found in a dusty riverbed by Nasa's Perseverance Rover, are dotted with intriguing markings nicknamed leopard spots and poppy seeds.

Located at a relatively close distance of 41 light years from Earth, the Trappist-1 system has attracted significant attention since its discovery in 2016. Three of the planets, Trappist-1d, Trappist-1e, and Trappist-1f (the third, fourth, and fifth planets from the star) lie within the habitable zone.

Though the days are fast ticking by, that success is far from assured. DART is the first-ever test of what NASA calls a kinetic impactor—a projectile intent on transferring its momentum to an asteroid in an elegant suicidal smash. In other words, the team plans to ram a speeding spacecraft into an asteroid to knock it off its path.
