COMIC: Our sun was born with thousands of other stars. Where did they all go?

Our sun was born in a cosmic cradle with thousands of other stars. Astrophysicists say they want to find these siblings in order to help answer the question: Are we alone out there?

Our own Milky Way is sending out neutrinos, the so-called 'ghost particles'

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 have found signs of a new kind of gravitational wave. It's really big

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.

Goodbye fuzzy donut: The famous first black hole photo gets sharpened up

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.

The James Webb Space Telescope is working as well as astronomers dreamed it would

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's primary mirror is made up of 18 hexagonal segments. Now that the telescope is in space, mission managers need to perfectly align them so the segments work as one giant mirror.

The first images from NASA's new space telescope show how it's coming into focus

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.
