Runaway Star Collisions Create Black Holes - Space.com   Fantastic collisions between two massive stars huddled in a cluster could fuel a series of mergers creating a black hole known as a middleweight. Two stars each weighing more than a hundred Suns come together, creating a superstar whose increased size and gravity make it a target for more impacts. In just a few million years -- a cosmic blink of the eye -- a ball of gas equal in mass to a thousand regular stars snowballs into existence.
Scientists To Develop Organic Analyzer To Find Life On Mars - SpaceDaily  Left:  Design of the portable capillary electrohoresis (CE) analysis device together with capillary sipper that will be used for analysis of amino acids in field sites. The Mars Organic Analyzer, dubbed MOA, looks not only for the chemical signature of amino acids, but tests for a critical characteristic of life-based amino acids: They're all left handed. Amino acids can be made by physical processes in space - they're often found in meteorites - but they're about equally left- and right-handed. If amino acids on Mars have a preference for left-handed over right-handed amino acids, or vice versa, they could only have come from some life form on the planet, Mathies said.

Siberia, The Big Bang of Life? - SpaceDaily  Trilobites, the primitive shelled creatures considered by many to be among the first animals to appear in the fossil record, may have originated in a place known today largely for its barren lifelessness: Siberia. By comparing separate, seemingly unrelated findings on trilobite evolution and geological history, UF's Joe Meert and KU's Bruce Lieberman concluded that precursors to modern continents began splitting off from a giant supercontinent at the South Pole about 580 million years ago, migrating north toward the equator for about 80 million years. The scientists' analysis suggests that originated in present-day Siberia when it was a separate continent from Asia and located much farther south.
