Cassini Raw Images

With its mirror segments aligned and its scientific instruments undergoing calibration, Webb is just weeks from full operation.

NASA's Lucy spacecraft observed the May 15-16, 2022, total lunar eclipse from 64 million miles from the Earth.

Completing a nearly 30-year marathon, Hubble has calibrated more than 40 "milepost markers" of space and time.

Dusty solar panels and darker skies are expected to bring the Mars lander mission to a close around the end of this year.

While the spacecraft continues to otherwise operate as normal, the mission team is searching for the source of a system data issue.

The next full moon is the Flower Moon and there will be a total lunar eclipse.

NASA has extended the planetary science missions of eight of its spacecraft due to their scientific productivity and potential to deepen our knowledge.

On April 30, 2022, a partial solar eclipse will be visible in parts of South America, Antarctica, and the Pacific and Southern Oceans.

The average global temperature on Neptune unexpectedly fluctuated during a recent 17-year period, according to a new study.

Webb will see the first galaxies to form after the big bang but to do that its instruments first need to get cold – really cold.

NASA's Hubble Space Telescope has determined the size of the largest icy comet nucleus ever seen by astronomers.

On Feb. 14, 2022, NASA’s Lucy spacecraft took a series of calibration images with its four visible-light cameras.
