Flight across Titan

No one really knew what Vesta looked like until NASA’s Dawn spacecraft decided to drop in on it. Now, images taken by the spacecraft have been stitched together to create a virtual flyover of the j...

This movie shows what it was like for NASA's Stardust spacecraft to fly by comet Tempel 1.

What astronomy highlights can you see in the sky in May 2020? Venus, Sirius and the Milky Way.

What's Up for March? Planet-palooza in the morning, a "Sirius" look at the Dog Star, and an evening trio at the end of the month.

Striking 3-D detail highlights a towering mountain, the brightest spots and other features on dwarf planet Ceres in a new video from NASA's Dawn mission.

This simulated voyage over the surface of Neptune's large moon Triton was produced using topographic maps derived from images acquired by NASA's Voyager spacecraft during its August 1989 flyby, 20 ...

Change is detected on Saturn’s moon Titan, in these three composite images from data taken during flybys in October 2005, January 2006 and March 2006 by NASA’s Cassini spacecraft.

What incredible things will the Cassini spacecraft at Saturn see and do over the next few years?

The tumbling and irregularly shaped moon Hyperion rotates away from the Cassini spacecraft in this movie taken during a distant encounter in Dec. 2005.

New science, mined from the archives. Data from NASA's Galileo orbiter launched a generation ago yields new evidence of plumes, eruptions of water vapor, from Jupiter's moon Europa.

Seeking August 2020 skywatching highlights? The Moon poses with the planets, and the Perseid meteors peak!

The history-making Viking 1 mission launched 35 years ago.

See all the planets, plus mission updates from comet and asteroid missions Dawn and Rosetta.

This image shows that NASA's Dawn mission detected abundances of hydrogen in a wide swath around the equator of the giant asteroid Vesta. The hydrogen probably exists in the form of hydroxyl or wat...

Animated Spacecraft

NASA's Dawn mission will be the first to explore a dwarf planet on March 6, 2015. This video details the spacecraft's approach and orbit insertion.

Everyone likes to check the weather in a far away destination before they travel there. This is especially true for spaceflight, where the destination may be where no one has gone before.

What can you see in the February sky? Stars and planets with distinct red and blue colors, like Mars and Sirius.

NASA’s Cassini mission will come to a spectacular close on September 15, 2017 after almost two decades in space since its launch in 1997.

This infrared movie from NASA's Cassini mission shows the churning of the curious six-sided jet stream at Saturn's north pole known as "the hexagon."

This movie shows a quick succession of multiple products of Titan's surface from the Cassini orbiter and the European Space Agency's Huygens probe.

This is an animated artist interpretation of the area surrounding the Huygens landing site, based on images and data returned Jan. 14, 2005.

The Dawn spacecraft visited the asteroid 4 Vesta for the time period May 3, 2011 to Sept. 5, 2012.

This movie, made from data obtained by NASA's Cassini spacecraft, shows Saturn's southern aurora shimmering over approximately 20 hours as the planet rotates.
