A new study from researchers at Rutgers University suggests that the best place to look for evidence of life on Mars is deep underground, where geothermal heat melted subsurface ice.

Most Unidentified Flying Objects aren't actually unidentified. Here's a list of phenomena, either natural or human-made, that people often mistake for UFOs.

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.
