Mind-Boggling Discovery in Australia, 'The Land 'Down Under' --"Could Forever Alter the Timeline of Human Migration"

As the "Land Down Under," Australia is an island continent, so ancient visitors would have to arrived by sea, a long way from where humans first evolved in Africa. Migration to Australia would have required some remarkable ingenuity. Archaeologists have...        

The Cosmos is One Big Particle Accelerator --"Paves the Way For a New Physics" (Center for Astrophysics)

Physicists are capitalizing on a direct connection between the largest cosmic structures and the smallest known objects to use the universe as a "cosmological collider" and investigate new physics. The cosmos' tiniest particles and the distribution of matter across the...        

Colossal Ring of Galaxies Discovered Expanding Like a 'Mini Big Bang' --"Could Force a New Understanding of Gravity" (Today's Most Popular)

Einstein's theory of gravity may have to be rewritten, after researchers at the University of St Andrews found a gigantic ring of galaxies darting away from us much faster than predicted. This 10 million light year-wide ring made up of...        

StarTalk Radio: "The Water Universe" --The Core of a Galaxy was Recently Discovered To Harbor 140 Trillion Times the Water in Earth's Oceans

We recently reported on an enormous galaxy that at its core contains an equivalent to 140 trillion times all the water in the world's ocean, surrounding a huge, feeding black hole, called a quasar, more than 12 billion light-years away....

NASA Scientists Grapple With a Profound Question --"How Will We Identify Alien Life That Might Be Unrecognizable?" (WATCH Today's 'Galaxy' Stream)

"If I start just doing the usual things to look for life that are successful for looking for life that we know on Earth, there's no reason to believe that it will be successful in identifying life that has even...        

Astrobiologists Propose Life Began on Land, Not In Ancient Oceans --"A Paradigm-Shifting Hypothesis"

A model for life beginning on land rather than in the sea could not only reshape our idea about the origin of life and where else it might be, but even change the way we view ourselves. For three years,...        

Evidence Detected of Ancient Impacts That Shaped the Milky Way

A team of astronomers has observed evidence of ancient impacts that are thought to have shaped and structured our Milky Way galaxy. Their research presents observational evidence of asymmetric ripples in the stellar disk of our galaxy, which had long...        

In-Depth Look At Theories About Tabby's Star Observed By the Kepler Space Observatory --Megastructure or Natural Phenomena? (WATCH Today's 'Galaxy' Stream)

Star KIC 8462852—“Tabby’s Star” named after its discoverer and Kepler astronomer, Tabetha Boyajian-—is emitting a transit signature that defies explanation. The luminosity of a star declines at a consistent rate when a planet passes in front, but not Tabby’s star...
