Celestial Boondocks: Study Supports the Idea We Live in a Void

Cosmicvoid1.jpg

A new study by a UW-Madison undergraduate not only firms up the idea that we exist in one of the holes of the Swiss cheese structure of the cosmos, but helps ease the apparent disagreement between different measurements of the Hubble Constant, the unit cosmologists use to describe the rate at which the universe is expanding today.

The World’s Most Powerful X-Ray Laser Beam Creates ‘Molecular Black Hole’

MolecularBlackHole.jpg

When scientists at the Department of Energy’s SLAC National Accelerator Laboratory focused the full intensity of the world’s most powerful X-ray laser on a small molecule, they got a surprise: A single laser pulse stripped all but a few electrons out of the molecule’s biggest atom from the inside out, leaving a void that started pulling in electrons from the rest of the molecule, like a black hole gobbling a spiraling disk of matter.

Scientists are now confident animal life on solid ground started with a few short bursts of marine creatures making the leap from the oceans. New research at the University of Portsmouth also paints a clear picture of how animals rapidly spread out and changed once they made the leap.

Collapsing Star Gives Birth to a Black Hole

Astronomers have watched as a massive, dying star was likely reborn as a black hole. It took the combined power of the Large Binocular Telescope (LBT), and NASA's Hubble and Spitzer space telescopes to go looking for remnants of the vanquished star, only to find that it disappeared out of sight.

A-tisket, A-tasket. You can tell a lot from a basket. Especially if it’s from ancient ruins of a civilization inhabited by humans 15,000 years ago. An archaeologist is among the team that made a groundbreaking discovery in coastal Peru – home to one of the earliest pyramids in South America. Thousands of artifacts, including elaborate hand-woven baskets, show that early humans in that region were a lot more advanced than originally thought and had very complex social networks.
