Europe and Japan's BepiColombo spacecraft, which launched in 2018, will fly by Earth on 10 April and use our planet's gravity to swing towards the inner solar system. Learn more about this mission and why we study Mercury.
Europe and Japan’s first Mercury mission will study how the planet formed.
The innermost planet is a contradictory mystery.
The Planetary Society is celebrating the 50th anniversary of Apollo 13, which launched on 11 April 1970. Disaster struck on 13 April, prompting the crew's infamous "Houston, we've had a problem" call for help. Learn what happened, and how NASA got the astronauts home safely on 17 April.
Apollo 13 was the 3rd attempt to land humans on the Moon and the 1st to fail. Fifty-six hours into the mission, an explosion forced the crew to abort their Moon landing and take shelter in the Lunar Module. The crew ultimately returned to Earth safely.

I love posting animations of Cassini images that I compose from frames grabbed from the mission's raw images website, but they are shoddy compared to the versions that eventually come out from the mission's imaging team.

Cassini's amazing cameras have set a new standard for the quality, sharpness, resolution, beautiful color, and all-around spectacularness of images returned from the outer solar system.

The Cassini imaging team have posted their own processed and captioned version of the Saturn's aurora movie that I posted a preview of about six weeks ago, and it was worth the wait.

Thanks to Mike Malaska for the tip on this one. The image is part of an animation that ends with Rhea transiting Saturn.

On "Questions and Answers" I answered this question: "How do they explain the hexagon near Saturn's north pole?"

On Planetary Radio's "Questions and Answers" I answered this question: "I read that Uranus got its tilt when it was hit by another object. What does it mean for a ball of gas to be hit -- wouldn't another object just pass through it?"

Here's a neat animation captured last month by Cassini and assembled by Mike Malaska: spokes in Saturn's B ring.

So many goodies on the Cassini raw images website lately! I am especially excited when Cassini takes photos through red, green, and blue filters so that it's possible to create views that look roughly like what you'd see with your own eyes.

I've had two people write in to correct my Phoebe ring post from yesterday.

Last week, planetary astronomers Anne Verbiscer, Michael Skrutskie, and Doug Hamilton published a paper in Nature succinctly titled "Saturn's Largest Ring." In the paper, they announce the discovery, using the Spitzer infrared space telescope, of a gargantuan, previously unseen ring around Saturn, encompassing the orbit of Phoebe.
