The deeper astronomers gaze into the cosmos, the more they find it's a bizarre and violent universe.The research findings from this week's annual meeting of U.S. astronomers range from blue orphaned baby stars to menacing "rogue" black holes that roam our galaxy."It's an odd universe...

Scientists taking their first "sniffs of air" from planets outside our solar system are a bit baffled by what they didn't find: water.One of the more basic assumptions of astronomy is that the two distant, hot gaseous planets they examined must contain water in their...
