Monster telescope breaks ground, will offer deepest views of universe

What promises to be the most advanced and sensitive telescope in the world, the massive Thirty Meter Telescope, officially breaks ground Tuesday in Hawaii. When completed, it will offer the deepest and sharpest views of our universe yet.<p>This thing is a monster. At 30 meters (98 feet), the TMT's …

NASA’s Latest Space Drive Breaks The Laws Of Physics

It is one of the most fundamental laws of physics: Every action has an equal and opposite reaction. We all learned it in high school. It’s a principle we use every day, just by existing. And it might just have been proven to be completely wrong in a lab.<p>This requires some explaining. Space travel …

NASA readies Mars 'flying saucer' for risky hypersonic flight test

The wispy atmosphere of Mars is 99 percent thinner than Earth's -- not great for slowing down space ships or metorites. NASA's testing a way to make it work, however, using a helium balloon, rockets and a Low Density Supersonic Decelerator (LDSD) vehicle, which looks suspiciously like a UFO. The …

APOD: Illustris Simulation of the Universe (2014 May 12) Video Credit: Illustris Collaboration, NASA, PRACE, XSEDE, MIT, Harvard CfA; Music: The Poisoned Princess (Media Right Productions) http://apod.nasa.gov/apod/ap140512.html Note: Today's APOD is a video so please be sure to click the above link to view it. Explanation: How did we get here? Click play, sit back, and watch. A new computer simulation of the evolution of the universe -- the largest and most sophisticated yet produced -- provides new insight into how galaxies formed and new perspectives into humanity's place in the universe. The Illustris project -- the largest of its type yet -- exhausted 20 million CPU hours following 12 billion resolution elements spanning a cube 35 million light years on a side as it evolved over 13 billion years. The simulation is the first to track matter into the formation of a wide variety of galaxy types. As the virtual universe evolves, some of the matter expanding with the universe soon gravitationally condenses to form filaments, galaxies, and clusters of galaxies. The above video takes the perspective of a virtual camera circling part of this changing universe, first showing the evolution of dark matter, then hydrogen gas coded by temperature (0:45), then heavy elements such as helium and carbon (1:30), and then back to dark matter (2:07). On the lower left the time since the Big Bang is listed, while on the lower right the type of matter being shown is listed. Explosions (0:50) depict galaxy-center supermassive black holes expelling bubbles of hot gas. Interesting discrepancies between Illustris and the real universe do exist and are being studied, including why the simulation produces an overabundance of old stars. http://www.illustris-project.org/people/ http://www.nasa.gov/ http://www.prace-ri.eu/ https://www.xsede.org/ http://web.mit.edu/physics/people/faculty/vogelsberger_mark.html http://www.cfa.harvard.edu/ http://www.mediarightproductions.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140512 #APOD
