Exoplanets

A research team has shed more light on how Luke Skywalker's home planet of Tatooine could orbit two stars, which are themselves bound together in an orbital dance

Astronomers have come up with a shopping list of what a planet needs to support life, perhaps even better than our Earth does, making them "superhabitable." Michael Moyer reports 

 

Earlier this week I had the very great pleasure of catching up with Lee Billings, the author of Five Billion Years of Solitude, a beautifully written and provocative new book about the quest to find other Earths, other life in the universe.

Robotic exploration of space is fascinating, complex and quite important to our understanding of the universe. To learn more about how scientists and engineers overcome challenges of robotic space exploration for successful data collection, join us for a live chat today (Tuesday, October 29) at noon EDT with Chris Impey, astronomer and author of Dreams of [...]

                          On November 14th 1971 NASA’s Mariner 9 became the first spacecraft to successfully orbit another planet.

Tomorrow’s Nobel Prize in physics is widely anticipated to go to Peter Higgs, perhaps along with Francois Englert, for their nearly 50-year-old prediction of a new particle that we now call the Higgs boson.

The list of known exoplanets is growing so long, so fast, that it is becoming difficult to properly appreciate the new discoveries. For those of us who grew up when our solar system accounted for the only nine worlds known in the entire universe, how are we to grasp the fact that astronomers now discover [...]

Although NASA’s planet hunting mission Kepler seems unlikely to return to a fully functioning state, after another reaction wheel failure, it has already yielded an extraordinary crop of new worlds.
