'Big baby' galaxy detected in early universe











WASHINGTON (Reuters) -- Astronomers using two of NASA's most powerful telescopes said on Tuesday they have detected a "big baby" galaxy, vastly heavy for its young age and its location in the early universe.

The discovery was surprising, since astronomers have long theorized that galaxies form when stars gradually cluster together, with small galaxies preceding bigger galaxies.

But the stars in this cosmic infant -- less than 1 billion years old -- have eight times the mass of those in the 13-billion-year-old Milky Way, which contains Earth.

Live giant squid caught on camera










A live, adult giant squid has been caught on camera in the wild for the very first time.
Japanese researchers took pictures of the elusive creature hunting 900m down, enveloping its prey by coiling its tentacles into a ball. The images show giant squid, known as Architeuthis, are more vigorous hunters than has been supposed. The images, captured in the Pacific Ocean, appear in the journal Proceedings of the Royal Society B.

Cleopatra Found Depicted in Drag













A relief image carved approximately 2,050 years ago on an ancient Egyptian stone slab shows Cleopatra dressed as a man, according to a recent analysis of the artifact.

The object is only one of three known to exist that represent Cleopatra as a male. The other two artifacts also are stelae that date to around the same time, 51 B.C., at the beginning of Cleopatra's reign.

Researchers theorize that the recently discovered 13.4 x 9.8-inch stela probably first was excavated in Tell Moqdam, an Egyptian city that the ancient Greeks called Leonton Polis, meaning "City of the Lions."

Flint remains show Stone Age life



A Stone Age settlement uncovered in the North Downs is being hailed as an important archaeological find. The site at Bletchingly, Surrey, is undisturbed and could show where people gathered in Mesolithic dwellings. Archaeologist Becky Lambert said: "We are plotting the exact location of the flint, so we might even be able to see patterns of where people were sitting."
Flint is often found during ploughing - this undisturbed site may reveal hearths and where food was made.

Asteroids Caused The Early Inner Solar System Cataclysm


















University of Arizona and Japanese scientists are convinced that evidence at last settles decades-long arguments about what objects bombarded the early inner solar system in a cataclysm 3.9 billion years ago.

Ancient main belt asteroids identical in size to present-day asteroids in the Mars-Jupiter belt -- not comets -- hammered the inner rocky planets in a unique catastrophe that lasted for a blink of geologic time, anywhere from 20 million to 150 million years, they report in the Sept. 16 issue of Science.

However, the objects that have been battering our inner solar system after the so-called Late Heavy Bombardment ended are a distinctly different population, UA Professor Emeritus Robert Strom and colleagues report in the article, "The Origin of Planetary Impactors in the Inner Solar System."

WASHINGTON (Reuters) -- A supermassive black hole appears to be homeless in the cosmos without a galaxy to nestle in, Hubble Space Telescope scientists reported on Wednesday.
Most monster black holes lurk at the heart of massive galaxies, slurping up matter from the galactic center with a pull so strong that nothing, not even light, can escape.

But a team of European astronomers reported in the journal Nature that a particular black hole some 5 billion light-years away has no evidence of a host galaxy. A light-year is about 6 trillion miles (10 trillion km), the distance light travels in a year.

ILULISSAT, Greenland (AP) -- The gargantuan chunks of ice breaking off the Sermeq Kujalleq glacier and thundering into an Arctic fjord make a spectacular sight. But to Greenlanders it is also deeply worrisome.
The frequency and size of the icefalls are a powerful reminder that the frozen sheet covering the world's largest island is thinning -- a glaring sign of global warming, scientists say.

Temple near Nile has been source of controversy

Near the Nile River lies a temple complex called Karnak in what was once ancient Thebes and is now modern Luxor. The great Temple of Amun or Amen-Ra was a principal focus of Egyptian religious activity for millennia but what makes Karnak of particular interest is the controversy over its use.The British astronomer Sir Norman Lockyer visited the site around 1890 and was struck by an immense corridor that ran the length of the complex. Lockyer believed that it was aligned westward across the Nile River to the midsummer sunset around 4000 B.C. It was quickly pointed out, however, that hills across the Nile from the temple blocked out any view of the setting sun, throwing the theory into doubt. Another astronomer did some quick calculations and found that the corridor only matched up with the sunset in 11,700 B.C. Even the Egyptians were not building temples that far back in time.

MIT Researchers Find Clue To Start Of Universe

















If you want to hear a little bit of the Big Bang, you're going to have to turn down your stereo.
That's what neighbors of MIT's Haystack Observatory found out. They were asked to make a little accommodation for science, and now the results are in: Scientists at Haystack have made the first radio detection of deuterium, an atom that is key to understanding the beginning of the universe. The findings are being reported in an article in the Sept. 1 issue of Astrophysical Journal Letters.

The team of scientists and engineers, led by Alan E.E. Rogers, made the detection using a radio telescope array designed and built at the MIT research facility in Westford, Mass. Rogers is currently a senior research scientist and associate director of the Haystack Observatory.

After gathering data for almost one year, a solid detection was obtained on May 30. The detection of deuterium is of interest because the amount of deuterium can be related to the amount of dark matter in the universe, but accurate measurements have been elusive. Because of the way deuterium was created in the Big Bang, an accurate measurement of deuterium would allow scientists to set constraints on models of the Big Bang.

Groundbreaking Research Sheds Light On Easter Island's Ancient Mystery

A researcher at Rochester Institute of Technology is unraveling a mystery surrounding Easter Island. William Basener, assistant professor of mathematics, has created the first mathematical formula to accurately model the island’s monumental societal collapse.

Between 1200 and 1500 A.D., the small, remote island, 2,000 miles off the coast of Chile, was inhabited by over 10,000 people and had a relatively sophisticated and technologically advanced society. During this time, inhabitants used large boats for fishing and navigation, constructed numerous buildings and built many of the large statues, known as Tiki Gods, for which the island is now best known. However, by the late 18th century, when European explorers first discovered the island, the population had dropped to 2,000 and islanders were living in near primitive conditions, with almost all elements of the previous society completely wiped out

Neanderthals and modern man shared a cave

The first certain proof that Neanderthal man and modern humans coexisted in Europe has emerged from a cave in central France. Radiocarbon dates show that modern people camped in the Châtelperron cave, 25 miles northeast of Vichy, about 40,000 years ago, preceded and then followed by two episodes of Neanderthal occupancy.

The differing occupations are demonstrated by their distinctive stone tools: those of the Neanderthals, known as Mousterian after the Dordogne site where they were first recognised, are made mainly from flint flakes. The Aurignacian toolkit of Homo sapiens sapiens uses parallel-sided blades, prised off the flint core in a more complex manufacturing sequence that allows better use of raw materials.
