Ignoring One Trillion Galaxies in the Observable Universe: Astrophysicists Use Mathematical Logic to Doubt the Probability of Extraterrestrial Life & 5 new Items:

Carl Sagan said that "extraordinary claims, require extraordinary evidence." In a stunning display of mathematical logic vs common sense, David Spiegel of Princeton University and Edwin Turner from the University of Tokyo have published a paper on arXiv that turns the Drake equation upside using Bayesian reasoning to show that just because we evolved on Earth, doesn’t mean that the same occurrence would necessarily happen elsewhere; "using evidence of our own existence doesn’t show anything" they argue, "other than that we are here."

Was Earth Once Orbited by Several Moons? And, Were They a Key to Life? The history of planet Earth is a fascinating story, involving catastrophic collisions with other small planets and a plethora of asteroid impacts. Recent findings show that our large moon was essential for the origin and evolution of life. Without the...

Image of the Day: Hyperwinds of the Universe A superwind, such as the one in stunning spiral galaxy NGC 3079 originates in the center of the galaxy, either from activity generated by a central supermassive black hole, or by a burst of supernova activity. Superwinds are thought to...

Found! Earth's Long-Sought Trojan Companion Asteroid 2010 TK7 is circled in green, in this single frame taken by NASA's Wide-field Infrared Survey Explorer, or WISE. The majority of the other dots are stars or galaxies far beyond our solar system. Astronomers discovered this object --...
