Scientists in Germany have created a new family tree of our Milky Way galaxy, showing how it has grown over billions of years from chaotic mergers with smaller galaxies.

This video, merging more than 2 decades of footage from SOHO cameras, captures thousands of sunspots, flares, and coronal mass ejections breaking out from the sun.

The 3rd data release from the Gaia mission will provide astronomers with a "treasure trove" of information they didn't have before. As they analyze Gaia's data in the years ahead, we're sure to learn new and surprising things about our home galaxy, the Milky Way.

Prior to Comet 2019 LD2, discovered last year, astronomers had never witnessed a comet in the process of orbiting from being between Jupiter and Neptune to orbiting inside Jupiter's orbit. Now ... witness the power of gravity!

Fast-moving gas from a young star - located in a star-forming region 400 light-years away - is giving astronomers insight into how planets form.

A new survey of our galaxy by astronomers with VERA in Japan has shown that Earth is both moving faster and is closer to the supermassive black hole at the center of our galaxy than previously thought. But don't worry, our planet is safe!

The Hubble Space Telescope has captured never-before-seen images of the rapid fading of the Stingray Nebula. This nebula is a cloud in space, surrounding a dying star.

The much-anticipated 3rd data release from the Gaia space observatory happened today.

New video shows Arecibo's receiver platform breaking loose and falling onto the radio telescope dish 400 feet below. No one was injured.

Where did the famous mystery Wow! signal, detected in 1977, come from? Astronomer Alberto Caballero might have pinpointed the host star. It's a sunlike star 1,800 light-years away, in the direction of the center of our Milky Way.
