There is an asteroid threat and space debris workshop in Scotland this week that Planetary Society support helped lead to, and that will include two public lectures you can tune into live.
Earth and its solar system compatriots all have nearly circular orbits, but many exoplanets orbit their stars on wildly eccentric paths. Is our home system strange? Or is our sense of the data skewed?

Learn about the formation and origin of the Solar System and go beyond our neighborhood to investigate exoplanets (planets around other stars) in this video of class 11 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
What can a 45-year-old mission to the Moon tell us about a "meteorite" flying past a skydiver on Earth?

Explore the worlds beyond Neptune including Pluto, Kuiper Belt Objects and comets in this video of class 10 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
How did planets originate? This is a question that has puzzled scientists for centuries, but one which they have been able to tackle directly only in the last few decades, thanks to two major developments: breakthroughs in telescope technology and ever-increasing computing power.

Update from Debra Fischer and her team on the intriguing results of their observations of the main Alpha Centauri stars, as well as future plans.
On the heels of last weeks reports of a second Sedna and a ringed Centaur comes a third cool outer solar system discovery: A new, likely large member of the Kuiper belt. With an absolute magnitude of about 3.0, the new object currently known as 2013 FY27 is the tenth brightest object beyond Neptune .
She’s alive! She’s alive! Or is she? A little more than a week ago, at the Lunar and Planetary Science Conference 2014, evidence was presented that Venus was geologically active, not in the recent past, like 100,000 years ago, but right now.
Yesterday, a team of astronomers announced that they discovered a set of planet-like rings around Chariklo, an asteroid-like body that currently resides in the unstable region between the orbits of Saturn and Uranus.
2012 VP113 is a new world that has been discovered on a Sedna-like orbit. What does that mean? It could imply the existence of a planet X, but doesn't prove it. It does suggest that a lot more Sednas are waiting to be discovered.
