"We're not sure exactly where in the sun the magnetic field is created," said Dean Pesnell, a space scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It could be close to the solar surface or deep inside the sun – or over a wide range of depths."

The Dark Energy Enigma –“The Entire Universe is Being Pushed by an Unknown Force No One Can Locate”

"Dark energy is incredibly strange, but actually it makes sense to me that it went unnoticed," said Noble Prize winning physicist Adam Riess in an interview. "I have absolutely no clue what dark energy is. Dark energy appears strong enough to push the entire universe – yet its source is unknown, its location is unknown and its physics are highly speculative."

Martin Bojowald, a professor of phycics at Penn State University, presents his fascinating ideas about “Loop Quantum Cosmology” in Once Before Time: A Whole Story of the Universe. "Will we ever," Bojowald asks, "with a precision that meets scientific standards, see the shape of the universe before the big bang? The answer to such questions remains open. We have a multitude of indications and mathematical models for what might have happened. A diverse set of results within quantum gravity has revealed different phenomena important for revealing what happened at the big bang. But for a reliable extrapolation, parameters would be required with a precision far out of reach of current measurement accuracies.

Apollo Mission Moon Rocks –“Evidence of a Head-On Collision 4.5 Billion Years Ago”

The moon was formed by a violent, head-on collision between the early Earth and a "planetary embryo" called Theia approximately 100 million years after the Earth formed, UCLA geochemists and colleagues report. Scientists had already known about this high-speed crash, which occurred almost 4.5 billion years ago, but many thought the Earth collided with Theia at an angle of 45 degrees or more — a powerful side-swipe (simulated in this 2012 YouTube video). New evidence reported Jan. 29 in the journal Science substantially strengthens the case for a head-on assault.

Colossal Cloud Ejected From Milky Way 70 Million Years Ago –Plummeting Back!

Since astronomers discovered the Smith Cloud, a giant gas cloud plummeting toward the Milky Way, they have been unable to determine its composition, which would hold clues as to its origin. Astronomers have now determined that the cloud contains elements similar to our sun, which means the cloud originated in the Milky Way’s outer edges and not in intergalactic space as some have speculated.
