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.

This week I'll be talking with NEOWISE principal investigator Amy Mainzer about moving objects that the WISE mission has spotted both inside and outside our solar system.

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.

Last week, the team put all of the data from Deep Impact's deep-sky imaging session online, and challenged visitors to see what they could make from it. I made some photos of M51, but there were some challenges.

Citizen Science projects let volunteers easily contribute to active science programs. They're useful when there is so much data it overwhelms computing algorithms (if they exist) or the scientific research team attempting to process it.
