Clash of the Titans: Hubble’s Universe Unfiltered

Posted by

Astronomers have known for decades that our Milky Way Galaxy and the neighboring Andromeda Galaxy are approaching each other. What we haven’t known is just how close the encounter will be. Recent Hubble measurements have been able to pin down the trajectory with a smashing conclusion: in about four billion years the two galaxies will crash together in a nearly head-on collision. Further, the spiral galaxies will have completely merged and transformed to create a single elliptical galaxy around six billion years in the future.

“Hubble’s Universe Unfiltered” is a recurring broadcast from HubbleSite.org, online home of the Hubble Space Telescope. Astrophysicist Frank Summers takes viewers on an in-depth tour of the latest Hubble discoveries. Find more episodes at HubbleSite.org.

Ken Jennings: Watson, Jeopardy and me, the obsolete know-it-all

Posted by

Trivia whiz Ken Jennings has made a career as a keeper of facts; he holds the longest winning streak in history on the U.S. game show Jeopardy. But in 2011, he played a challenge match against supercomputer Watson — and lost. With humor and humility, Jennings tells us how it felt to have a computer literally beat him at his own game, and also makes the case for good old-fashioned human knowledge. (Filmed at TEDxSeattleU.)
