The Alien Observatory --"The Mystery of Where Alien Life is Hiding Deepens"   

      "After searching the skies for Earthlike planets for centuries, cosmologists have, in the last two decades, broken open the cosmic piñata. Today they estimate as many as 500 billion billion sunlike stars, with 100 billion billion Earthlike planets. The more we learn about the universe, the more absurd it would seem if all but one of those bodies were bereft of life. To my mind, this is both the least likely answer to Fermi's Paradox and the only one that fits all ...

Ancient "Red Nuggets" Detected --Relics of the 1st Massive Galaxies in the Universe with Gigantic Supermassive Black Holes  

  Red nuggets are relics of the first massive galaxies that formed within only one billion years after the Big Bang. While most red nuggets merged with other galaxies over billions of years, a small number remained solitary. These relatively pristine red nuggets allow astronomers to study how the galaxies — and the supermassive black hole at their centers — act over billions of years of isolation.   A new study using data from NASA's Chandra X-ray Observatory indicates tha...

"Cosmic Sleuths" --Missing Baryons of the Universe Found Hidden Between an Ancient Quasar and Our Solar System  

      Ordinary, baryonic, matter exists in the vast spaces between galaxies as highly-ionized oxygen gas at temperatures of about 1 million degrees Celsius. To pin down the missing third, the researchers used the radiation emanating from a distant, ultra-bright black hole called a quasar. That lost matter exists as filaments of oxygen gas at temperatures of around 1 million degrees Celsius that lie in the space between galaxies, said CU Boulder's Michael Shull, a co-auth...

Today's "Planet Earth Report" --'In Race Against Climate Change, Archaeologists Search for "Lost Colony" of the New World' (WATCH Video)  

    In 1587, more than 100 men, women, and children settled on Roanoke Island in what is now North Carolina. War with Spain prevented speedy resupply of the colony—the first English settlement in the New World, backed by Elizabethan courtier Sir Walter Raleigh. When a rescue mission arrived 3 years later, the town was abandoned and the colonists had vanished. What is commonly called the Lost Colony has captured the imagination of generations of professional and amateur sleuths...
