Would you like to be part of one of the largest citizen-science efforts in the history of astronomy? The International Occultation Timing Association (IOTA) invites you to join in the campaign to observe and time the best and brightest asteroid occultation ever predicted to occur over a populated area – and no telescope is required!

Juno's Earth flyby represented the first opportunity for many of the science instruments to be used on a planetary target. There were terrific photos of Earth and the Moon, plus a cool project to see if Juno could detect intelligent life on Earth.

From October 6 to 11, two divisions of the American Astronomical Society - Planetary Science and History - are meeting together for a combined annual conference. There will be several opportunities for the public to participate: a free public talk, several webcast lectures, a special online event for the Juno flyby of Earth, and a pro-am workshop on how amateur astronomers can contribute to planetary science.

The Mars I study is really active; the surface constantly changes. We have collected a lot of image data about changing seasonal features near the south pole. There is so much that we can't analyze all of it on our own. We need your help, through a new Zooniverse project named PlanetFour.

A change in the Kepler data delivery process provides both scientists and the public to get involved in planet discovery.
