All 4 of the gas giant planets in our solar system - Jupiter, Saturn, Uranus, and Neptune - are known to have rings. Could many of the so-called super-puff or cotton candy exoplanets have rings instead of super low densities?

Juno arrived at Jupiter in 2016. It's in a 53-day orbit around the planet. Close sweeps past the planet are called "perijoves" (peri means "near"). Here are some spectacular images from the most recent sweep, Perijove 25, in February.

This just in ... a new super-cool composite from Curiosity on Mars. The panorama contains more than 1,000 images taken last Thanksgiving and assembled over the past few months ... 1.8 billion new pixels of Martian landscape!

Physicists at MIT analyzed data from earlier experiments in particle accelerators, in order to probe the workings of the strong nuclear force that operates inside atoms. Their work sheds light on this force - one of the 4 fundamental forces of nature - and also illuminates the structure of a neutron star’s core.

A new study by researchers at Cambridge University suggests that the giant exoplanet K2-18b - a mini-Neptune - may be more potentially habitable than previously thought.

NASA has issued a public challenge where you can help design a critical sensor that would be needed for a future rover on Venus.

Scientists studying a distant galaxy cluster have discovered the biggest explosion seen in the universe since the Big Bang.

Late in the day on Thursday, astronomers released this new image of 2020 CD3, a small object now confirmed to be orbiting Earth temporarily. It was apparently captured into Earth orbit 3 years ago. Its fate, here.

The results from NASA's Mars InSight lander's first 10 months on the Martian surface have been published in a series of papers.

A new study from researchers in Tokyo helps explain how cosmic rays affect prebiotic organic chemistry in the atmosphere of Saturn's moon Titan.
