Analyzing deep-sea samples of stardust that fell to Earth over millions of years, researchers made a surprising discovery about how frequently far-away stars produce heavy elements like gold and uranium.

Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel) and, if that were true, it would be 'stable and navigable'. This is the hypothesis put forward in a new study.

On Christmas Day 2003, a kitchen table-size lander descended onto the surface of the red planet on a mission to study the Martian surface and potential clues for life. The probe never called home, and no one knew what happened to it. Until now.

The theory that an Anthropic Principle guided the physics and evolution of the universe was initially proposed by Brandon Carter; this theory was later debated by Cambridge scholar Stephen Hawking and a widening web of physicists around the world. German scholar Ulf-G Meissner adds to a series of discoveries that support this Anthropic Principle.

The catalogues of celestial objects contain a galaxy cluster called 'Abell 4067'. Recent observations with the XMM-Newton space observatory, however, reveal evidence that this object actually constitutes of the merger of two clusters. The smaller system appears to be losing the greater part of its gas.

Astronomers have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars - extremely luminous objects powered by supermassive black holes with the mass of a billion suns - regulate the formation of stars and the build-up of the most massive galaxies.
