The astronomy world is abuzz today because of ESA's announcement of the first release of data from the Gaia mission. Gaia is a five-year mission that will eventually measure the positions and motions of billions of stars; this first data release includes positions for 1.1 billion of them, and proper motions for 2 million.
NASA’s next big “flagship” astronomy mission, following the ambitious James Webb Space Telescope due to be launched in 2018, is currently known as the Wide Field Infrared Survey Telescope (WFIRST)—but it's had a slew of different names.
Cosmologist Jason Rhodes details the path he took to play a leading role in a European mission designed to learn about dark energy.
Jason Perry brings us a report on recent ground-based observations that shed new light on the most powerful of Io’s volcanic eruptions.
Will New Horizons have a mission after Pluto? Ground-based searches have failed to turn up anything that New Horizons can reach. Now Hubble is joining the search, but time is running out: a discovery must be made within the next two months.

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.
Discover the Universe including the Big Bang, dark matter, dark energy, galaxies, life and more in this video of class 13 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
Cosmos with Cosmos Episode 10: The Edge of Forever
In which we contemplate the end of all things
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.
Cosmos with Cosmos Episode 8: Journeys Through Space and Time
Are we imprisoned in both?
Sagan makes us confront the limitations of our mortality given the immensities of space and time presented to us by the cosmos.
We interview Dr. Franck Marchis from the SETI Institute about nanosats that can unfold in space to create sensitive telescopes that are orders of magnitudes cheaper than current hardware.
Astronomy Enters a New Era
Join us for a live webcast about thrilling new tools that will come online in the next decade.
A live conversation about just a few of the powerful new instruments that will revolutionize our knowledge of the cosmos once again.
This year's American Astronomical Society meeting featured tons and tons of news on exoplanets. They're everywhere! And not just planets, but also asteroids, comets, and more....

NuSTAR, the most sensitive X-ray telescope ever developed, launched successfully at 16:00 UT. This was a fun launch to watch, because the launch vehicle was a Pegasus XL air-launched rocket, dropped like a bomb from open bay doors of an L-1011 airplane.
