Scientists have detected these strange particles from outer space before, but this is the first time they've caught cosmic neutrinos from our own Milky Way

Scientists say they've found evidence of a very long gravitational wave that could open a window onto supermassive black holes — and perhaps even other extreme, unseen objects in the universe.

Scientists have created a new version of a historic black hole image that was first unveiled back in 2019. The central black nothingness now looks larger and darker.

Picture perfect: Mission managers say the telescope's mirror segments have been aligned and have focused on single stars, a critical milestone, and the telescope is working flawlessly.

The James Webb Space Telescope has seen its first starlight, but its 18 mirror segments aren't yet perfectly aligned. As a result, the pictures it's sending back now aren't exactly cosmic eye candy.

NASA should work toward a new space telescope that could view small planets around distant stars with the potential to host life, expert panel says

An article suggests the natural light show starts when disturbances on the sun pull on Earth's magnetic field, creating cosmic waves that launch electrons into the atmosphere to form the aurora.
