A nearby planet named Gliese 12 b has an estimated surface temperature of 42°C (108°F), making it a promising candidate for liquid water and maybe life

The European Space Agency’s Euclid space telescope has taken images of galaxies, galaxy clusters and newborn stars in unprecedented detail

Scientists have long thought the source of the sun's magnetic field sat deep within the star, but it may exist in a far more convenient spot for us to observe it

Estimates suggest there are trillions of free-floating worlds in our galaxy alone. Most of them will be frozen planets like Pluto, but some might be warmer – and possibly even habitable

For the first time, astronomers have observed the area right at the edge of a black hole where matter stops orbiting and plunges straight in at near light speed

Gravitational waves can be lensed by massive galaxies so that they repeat, like an echo. Scientists are now readying to snare their first one and explore the cosmic secrets it holds
