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.
Cosmos with Cosmos Episode 12: Encyclopedia Galactica
In which we ponder the existence of others
Cosmos returns in fine form in its penultimate episode. Sagan explores the historical and scientific precedents for the search for extraterrestrial life (SETI) and our human desires to not be alone in the universe.
The astronomy world is all a-twitter this morning over the discovery of a new supernova in M82, a galaxy that's in our astronomical backyard, "only" 12 million light-years away. And early word is that it appears to be a Type Ia supernova, the kind that's used as a standard candle to measure the expansion of the universe.
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 9: The Lives of the Stars
In which we are star stuff
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.
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.

The world's great telescopes capture stunning photographs of stars, nebulae, and other sky phenomena. In Europe to the Stars, authors Govert Schilling and Lars Lindberg Christensen share many such photos. But the real stars of this book are the great telescopes of the European Southern Observatory.
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.
The extended, mostly unedited recordings of my conversations with many of the people I spoke to at the ALMA Observatory in Chile. Also, the full English translation of Chilean President Sebastian Pinera's speech.

The second in a series of audio blogs chronicling my trip to the driest spot on Earth, Chile's Atacama desert, to see the inauguration of the ALMA Observatory. Al Wootten and Alison Peck tell the story of ALMA.
How come Hubble's pictures of galaxies billions of light years away are so beautifully detailed, yet the pictures of Pluto, which is so much closer, are just little blobs? I get asked this question, or variations of it, a lot. Here's an explainer.
My solar system chauvinism is well-established, but I am as much a sucker for beautiful astrophotos as the rest of you. Once in a while I get a media advisory from the European Southern Observatory about a new pretty picture posted on their website, and then I inevitably lose an hour following links to one stunner after another.
A measurement of the Andromeda galaxy's proper motion shows it's coming directly at us, and will collide with the Milky Way in 4 billion years. The event will transform the appearance of our night sky.
There is an ever-expanding bubble announcing Humanity's presence to anyone listening in the Milky Way.

Cary and Michael Huang present a basic "powers of ten" visualization starting at human scale from which you can scrub downward smaller than quarks or upward to the scale of the entire universe.
