Recently, NASA scientists combined data from the Spitzer and Hubble Space Telescopes to discover the most distant galaxy known to date. The galaxy, named Abell2744 Y1, was formed around 13.2 billion years ago when the universe was extremely young. As the universe is expanding, Abell2744 Y1 is currently closer to 40 billion light years away from us, an astounding distance.

Most of us have trouble visualizing the height of buildings, or the distance it takes to get home from work, let alone things on an intergalactic scale. Even cooler are the tidbits of information that are provided when you click on an object. 1. This is the smallest unit of scale in the universe. As you can see from the animation it takes a bit of zooming to reach this scale. 2. 3. 4.
Tres-4 is the second largest planet discovered so far. 5. 6. A New Thermodynamics Theory of the Origin of Life. Why does life exist?
Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.” From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat.
Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity. Kristian Peters Cells from the moss Plagiomnium affine with visible chloroplasts, organelles that conduct photosynthesis by capturing sunlight. The Smartest Book About Our Digital Age Was Published in 1929. Scott Eyman’s new life of the actor John Wayne portrays an extremely complicated man who invented his own public persona and played it beautifully.
“Truly, this man was the son of God.” Thus speaks a Roman centurion at the end of George Stevens’s inaptly named The Greatest Story Ever Told (1965). It’s a line that always gets a big laugh, partly because the idea of anything so irreligious as Hollywood hokum commenting on the provenance of Jesus Christ is axiomatically funny, but mostly because the centurion is played by John Wayne, a movie star who might have known a son of a gun when he saw one, but who patently knew precious little else.
Except, one learns from Scott Eyman’s exhaustive new biography, John Wayne: the Life and Legend, Wayne was a rather more cultivated man than his movie persona allowed. The Future of Airline Websites.
