Gobekli Tepe's Cosmic Blueprint Revealed

Report by Andrew Collins author of From the Ashes of Angels (1996), The Cygnus Mystery (2006) and Beneath the Pyramids (2009)

On a hilly ridge called Göbekli Tepe in the Taurus Mountains of southeast Turkey, near the ancient city of Sanliurfa, archaeologists have uncovered the oldest stone temple complex in the world. Constructed most probably during the second half of the tenth millennium BC, some 7,000 years before Stonehenge and the Great Pyramid, the site consists of a series of rings of enormous T-shaped pillars, many bearing carved reliefs of Ice Age animals, strange glyphs and geometric forms.

Monştrii spaţiului: gaura neagră NGC 1277

O gaură neagră cu masa de miliarde de ori mai mare decât cea a Soarelui este obiect de studiu şi de discuţii între cercetători. Monstrul cu pricina pare a-şi fi părăsit galaxia mamă şi a se fi instalat într-o altă galaxie, după o călătorie cu o viteză vertiginoasă.

Mai mult, gaura neagră a luat cu ea şi „prizonieri”, stele capturate din galaxia iniţială.

Dinosaur-killing space rock 'was a comet'

The space rock that hit Earth 65m years ago and is widely implicated in the end of the dinosaurs was probably a speeding comet, US scientists say.

Researchers in New Hampshire suggest the 180km-wide Chicxulub crater in Mexico was carved out by a smaller object than previously thought.

Many scientists consider a large and relatively slow moving asteroid to have been the likely culprit.

Big Bang’s afterglow shows universe is 80 million years older than scientists first thought

ARIS — A new examination of what is essentially the universe’s birth certificate allows astronomers to tweak the age, girth and speed of the cosmos, more secure in their knowledge of how it evolved, what it’s made of and its ultimate fate.

Sure, the universe suddenly seems to be showing its age, now calculated at 13.8 billion years — 80 million years older than scientists had thought. It’s got about 3 percent more girth — technically it’s more matter than mysterious dark energy — and it is expanding about 3 percent more slowly.
