The Planetary Society is launching a new collaboration with Yale exoplanet hunter Debra Fischer and her team, the Exoplanets Laser project. We will support the purchase of an advanced, ultra stable laser to be used in a complex system they are designing to push radial velocity exoplanet hunting to a whole whole new level.

The Twittersphere has been alive with speculation about a Gamma Ray Burst in the nearby galaxy M31. The problem is, there was never a claim of such an event, and it turns out that the tentative result that triggered this story was overstated.

Everyone loves a good mystery. In astronomy, there is nothing more exciting than an unexplained signal.

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?

Augusto Carballido

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.

Carl Sagan takes us from the birth to the death of the universe. How do we reconcile our place within a universe that will die? Join us for the latest discussion on episode 10 of Cosmos.

It's very nice to infer the existence of planets circling other stars. It's even better to see them. This new instrument has just become the most powerful exoplanet viewer yet created.

This episode highlights the other big idea in Cosmos: that we are profoundly connected with the universe around us. Our constituent parts are forged in the bellies of massive stars; we exist through their deaths.

Casey Dreier

Sagan makes us confront the limitations of our mortality given the immensities of space and time presented to us by the cosmos.
