+ - Billion Tonne Comet May Have Missed Earth By A Few-> 1

Submitted by
afree87
afree87 writes "A re-analysis of historical observations at a Mexican observatory suggests Earth narrowly avoided an extinction event just over a hundred years ago. On 12th and 13th August 1883, an astronomer at a small observatory in Zacatecas in Mexico made an extraordinary observation. This month, Hector Manterola at the National Autonomous University of Mexico suggests these were fragments of a comet. "If they had collided with Earth we would have had 3275 Tunguska events in two days, probably an extinction event.""

+ - Atmosphere Heated Up Before Japan Quake->

Submitted by afree87
afree87 (102803) writes "A new paper submitted to arXiv uses satellite data to contend that the ionosphere heats up before earthquakes. Observations from the DEMETER spacecraft show heat rising from the Pacific Ocean off Japan, spiking three days before the earthquake. "The thinking is that in the days before an earthquake, the great stresses in a fault as it is about to give cause the releases large amounts of radon.""

+ - Universe May Be Infinite->

Submitted by afree87
afree87 (102803) writes "Analyzing the latest observations of the visible Universe, astronomers have found it is at least 250 times bigger than anything we can detect, and may indeed be infinite: "They say that the curvature of the Universe is tightly constrained around 0. In other words, the most likely model is that the Universe is flat. A flat Universe would also be infinite and their calculations are consistent with this too." In an infinite universe, every anime is real."
