The Cassini spacecraft took one last, lingering look at Saturn and its splendid rings during the final leg of its journey.

Astronomers around the world will have immediate access to early data from specific science observations from NASA’s James Webb Space Telescope, which will be completed within the first five months of Webb’s science operations.

NASA's Cassini spacecraft ended its journey on Sept. 15 with an intentional plunge into the atmosphere of Saturn, but analysis continues on the mountain of data the spacecraft sent during its long life.

NASA’s Hubble Space Telescope is helping identify potential celestial targets for the James Webb Space Telescope.

A thrilling epoch in the exploration of our solar system came to a close  as NASA's Cassini spacecraft made a fateful plunge into the atmosphere of Saturn, ending its 13-year tour of the ringed planet.

NASA's Cassini spacecraft is headed toward its Sept. 15 plunge into Saturn, following a final, distant flyby of the planet's giant moon Titan.

As the Cassini spacecraft nears the end of a long journey rich with scientific and technical accomplishments, it is already having a powerful influence on future exploration.

NASA researchers say they have passed a major milestone in their quest to mature more powerful tools for detecting the atmospheres of giant exoplanets.

NASA’s James Webb Space Telescope will use its infrared capabilities to study the “ocean worlds” of Jupiter’s moon Europa and Saturn’s moon Enceladus.

It’s not a bird or a plane but it might be a solar storm.
