Using the James Webb Space Telescope, astronomers have discovered carbon dioxide and hydrogen peroxide at the surface of Pluto's largest moon, Charon, potentially shedding light on its origins.

The sun has unleashed the most powerful solar flare since 2017, just days after it spat out another monster explosion. Both outbursts have launched solar storms that will likely hit Earth this weekend and trigger vibrant aurora displays.

A rare nova explosion will soon bring a "new star" to the night sky, and scientists are excited.

On Oct. 2, a partial "ring of fire" solar eclipse was visible from the remote island of Rapa Nui, also known as Easter Island, where around 1,000 stone moai statues stand. You can see the whole celestial event play out in this incredible composite image.

Images captured by Curiosity's onboard cameras show several large tears in the tire of one of the rover's wheels. However, the damage does not appear to be slowing the roaming robot down.

The U.S. Federal Aviation Administration is investigating the uncontrolled reentry of part of a Falcon 9 rocket that delivered passengers to the International Space Station in a capsule that will return stranded astronauts Butch Wilmore and Suni Williams to Earth next year.

The Oct. 2 partial solar eclipse, known as an annular or "ring of fire" eclipse, is about to begin over Easter Island and South America. Watch it for free right here.

Astrophysicists estimate that any exponentially growing technological civilization has only 1,000 years until its planet will be too hot to support life.

The James Webb Space Telescope has zoomed in on an ancient supernova, revealing fresh evidence that a crisis in cosmology called the Hubble tension isn't going anywhere soon.

The sun just unleashed one of its largest solar explosions in recent years, temporarily causing a radio blackout on Earth and spitting out a coronal mass ejection that will likely collide with our planet this weekend.
