The Pentagon's Mysterious UFO Surveillance --"Real Alien Technology Obtained" (WATCH Videos)  

    WASHINGTON. In the $600 billion annual Defense Department budgets, the $22 million spent on the Advanced Aerospace Threat Identification Program was almost impossible to find. Which was how the Pentagon wanted it, according to today's reporting in The New York Times. For years, the program investigated reports of unidentified flying objects, according to Defense Department officials, interviews with program participants and records obtained by The New York Times. It was run

Today's Top Space & Science Headline --"Laws of Physics May Be a Sign of Extremely Advanced Alien Intelligence"  

    "It's a great mind-bending twist," says Caleb Scharf, director of astrobiology at Columbia University, "Perhaps hyper-advanced life isn't just external," says Scharf. "Perhaps it's already all around. It is embedded in what we perceive to be physics itself, from the root behavior of particles and fields to the phenomena of complexity and emergence." "It would neatly explain why we have yet to see advanced intelligence in the cosmos around us, Scharf adds in an ar...

Cassini has transmitted a hoard of valuable data from Saturn since it arrived at the planet in 2004.

Installed on ESO's Very Large Telescope (VLT) in Chile, ESPRESSO will search for exoplanets with unprecedented precision by looking at the minuscule changes in the light of their host stars. For the first time ever, an instrument will be able to sum up the light from all four VLT telescopes and achieve the light collecting power of a 1...
