Only three interstellar objects have ever been spotted. Here’s what we know about them and why they’re so cool.
Supernova remnants, stellar nurseries and more populate this new view of our galaxy, as seen from Earth’s southern hemisphere.
The odds of a big space rock striking the planet are higher than you might think. But don’t worry — asteroid strikes may be preventable.
Astronomers have detected these radiation belts around Earth and beyond. Jupiter’s belt is thousands of times as intense as Earth’s.
Astronomers want to know the source — and importance — of these faint, fast-moving clouds that zoom beyond and toward our Milky Way’s disk.
This supersized lunar event occurs when a full moon or new moon coincides with the moon’s perigee — the point where it is the closest to Earth.
Two black holes merged, creating a new, bigger one. This event triggered the clearest ripples in spacetime ever observed.
No one knows exactly what this stuff is, but it’s shaping our universe on the largest scales.
Equipped with the world’s largest digital camera, this new telescope is poised to help solve some of the universe’s biggest mysteries.
High-velocity space junk threatens space missions today. And the problem is growing.
