Hypervelocity stars travel across the Universe, perhaps with aliens in tow

hypervelocity starsThe stillness of the night sky is deceiving. Because of the sheer vastness of space, stars appear unmoving like celestial fixtures. In actuality, though, they're zipping through the cosmos - some at ridiculously high speeds: thousands, and even tens of thousands of kilometres per second.

That's roughly 100,000 times faster than the speediest train and 1,000 times faster than the fastest spacecraft that's ever flown. That's fast enough for a few spins around Earth in the time it takes to put on your socks. The point is, that's fast.


Largest-yet monument unearthed at Stonehenge

Stonehenge monumentStonehenge is the gift that keeps on giving -- the gifts being expansive, mysterious arrangements of massive stones.

Researchers in England recently found another monument at Stonehenge, just two miles from the original stone circle. Scientists say it may be the largest collection of stones at the site, and unlike anything else in the world.

The ancient monument was discovered buried beneath a grassy ridge at the southern edge of Durrington Walls, a sizable Neolithic settlement near Wiltshire, England. None of the stones have yet been unearthed, but were studied using ground-penetrating radar.


Ion collider produces droplets of primordial goo

primordial liquid produced in labhe Relativistic Heavy Ion Collider just spit out tiny droplets of a liquid researchers say resembles the seeds of the cosmos, a primordial goo created by the Big Bang, which existed only briefly before cooling into the matter that helped birth stars, galaxies and planets.

Scientists have reported seeing the tiny liquid droplets before, but this time, researchers got a better look at the production process.


Hawking: Info Can Escape Black Holes

Stephen HawkingStephen Hawking announced during a lecture at the KTH Royal Institute of Technology in Stockholm, Sweden on Tuesday that he has potentially solved the Information Paradox. The paradox a conflict between the quantum mechanics and general relativity models that has vexed physicists for more than four decades.

The Information Paradox arises from black holes -- specifically what happens to information about the physical state of objects that fall into one. The quantum mechanical model posits that the information remains intact while general relativity argues that it is indeed obliterated under the black holes immense gravitation. But Hawking has developed a third opinion: the information never actually makes it into the black hole. "I propose that the information is stored not in the interior of the black hole as one might expect, but on its boundary, the event horizon," he said.


Astronomers spot 20 million year young, 'Jupiter-like' planet

New Jupiter-like planetAstronomers have spotted a Jupiter-like planet that could hold the answer to how our solar system was formed.

The planet 51 Eridani b is roughly twice the size of Jupiter and young by planetary standards, at 20 million years old. At 800 degrees Fahrenheit, the planet's surface is still glowing with heat from its creation and offers clues about how it was formed, according to a study published in the journal Science on Thursday.


29 U.S. Scientists Praise Nuclear Deal in Letter to Obama

29 Scientists praise Iran dealTwenty-nine of the nation’s top scientists — including Nobel laureates, veteran makers of nuclear arms and former White House science advisers — wrote to President Obama on Saturday to praise the Iran deal, calling it innovative and stringent.

The letter, from some of the world’s most knowledgeable experts in the fields of nuclear weapons and arms control, arrives as Mr. Obama is lobbying Congress, the American public and the nation’s allies to support the agreement.


NASA's Kepler spacecraft spots planet 'somebody else might call home'

Kepler spavecraft finds earth twinScientists have spotted a planet much the same size as our Earth orbiting a star that closely resembles our sun, making this new world the most likely known place outside our solar system to harbor life.

The newfound planet, referred to as Kepler-452b, “is the closest thing we have to another place that somebody else might call home,” Jon Jenkins of NASA’s Ames Research Center told reporters Thursday. The planet has been at just the right temperature to boast liquid water for some 6 billion years, “a considerable time and opportunity for life to arise somewhere on its surface or in its oceans,” assuming the place has all the necessary ingredients for life, Jenkins said.
