The Mars Express team showcases some of the best viewing opportunities of Mars in 2014, including how to spot Comet Siding Spring when it flies past Mars this October.

With all the excitement happening on missions criscrossing the solar system, I often forget to enjoy the views of our solar system that we can achieve from home. Amateur astronomers don't make the same mistake. Here's a lovely photo that Stuart Atkinson sent me, captured last night from Kendal, England, showing four special wanderers.
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!
A new comet observing campaign for C/2013 A1 (Siding Spring)
You thought you were rid of us...but we're baa-aaack!

You thought you were rid of us...but we're back! Following the spectacular and, quite frankly unprecedented, success of the Comet ISON Observing Campaign, we are launching a similar venture for another unique cometary encounter that's happening this year. In October 2014, comet C/2013 A1 (Siding Spring) will pass extremely close to Mars.

NEOWISE has reawakened to discover more asteroids and comets. The mission leader thanks the amateur astronomers who follow up.

Can features on Neptune be observed by amateur astronomers? For years, the Hubble Space Telescope and some professional terrestrial observatories have been revealing incomplete belts and spots on the surface of Neptune. Now, spots have been imaged by amateurs.
For several weeks now, ground-based observers have been blind to Comet ISON as our local star was sitting directly between us and the comet. I am delighted to share two pieces of good news: first, that ISON is still alive and well, and secondly that it has been recovered.
Found a Killer Asteroid? Who Ya Gonna Call?

Astronomer Timothy Spahr directs the Minor Planet Center, the global clearinghouse for asteroids, comets and other relatively small objects in the solar system, including moons. He also coordinates the Society's Shoemaker NEO grant program.
Using a Planetary Society provided camera, Gary Hug in Kansas, USA discovered Potentially Hazardous Asteroid 2013 AS27 on Jan. 7, 2013. Shoemaker winner Bob Holmes provided the first follow up observations of this 140m-310m wide asteroid.
A very interesting comet has recently been discovered -- interesting because it will nearly graze the Sun in August 2013 and then approach Earth closely the following December. Whether it will turn out to be a great comet is impossible to know.

Hang out with Fraser Cain and amateur astronomers all over the world in Cosmoquest's Virtual Star parties conducted over Google+. Here's how -- plus an inspiring video produced by Google to show just how cool this is.
Telescope maker Celestron joined the Planetary Society at April's big festival in Washington. Their new video about the experience features our Emily Lakdawalla.
