Star Guide the Evolution of the Universe

 

For years, astronomers do not know anything about what happened during the "dark period" of the universe. That period is a period between the predicted big bang occurred 13.7 billion years ago with the creation of the first stars in the universe.

However, now a little enlightenment comes from the findings of scientists at Cambridge University, England, and California Institute of Technology, USA. They found the remains of the first stars that created the explosion of a star along with evidence in the form of clouds of gas.

Professor Max Pettini of Cambridge Institute of Astronomy are involved in the research said, "We have effectively track what happens in 'the darkness' by using the light that emitted a kuasar."

He continued, "We found a small number of elements in the residual gas cloud explosion of one of the first stars were present in very different proportions with the relative proportions that are found in stars today."

Pettini said, the ratio of carbon and iron contained in the gas cloud 35 times larger than that contained in the sun. Meanwhile, it also shows that the gas cloud caused by the explosion of a star that size 25 is larger than the sun.

Pettini who is a researcher at the Cambridge Institute for Astronomy explained, "These (gas clouds) is a fossil that can tell us trace the missing in the early formation of the universe."

He said the first star that provides the key to how the universe evolved from an environment rich in hydrogen and helium into oxygen-rich environment elements, carbon, and iron.

Facts About Space Travel

 

You aspire to become an astronaut? Or dreamed want to take a walk into space? Do not merely think of beautiful things beautiful. As quoted from the Discovery, there are several facts that "interesting" about the trip out of Earth's.

- Living Wreck
Research and space exploration have sacrificed a life of living beings, especially animals. If you think the expense of monkeys and dogs in the laboratory testing the name of science on Earth, is bad enough, imagine this.
A number of early space missions involving the procedure of re-entry into Earth. Unfortunately, not all succeed the space shuttle. It is estimated that, now more carcasses of dogs and simian, monkey species similar to humans, which has become a mummy continue to orbit the Earth until now.
- Air Leakage
Russian cosmonaut Alexei Leonov was the first walk in space in 1965 then. Unfortunately he was experiencing air leakage and experiencing stiff fabric that is not anticipated.
Material rigidity costume he attempted to force back into the capsule with difficulty. He was forced to reduce pressure inside the costume with a material risk that squash her into the costume.
Not finished there, Voskhod, which he rode the plane missed the point and landed near the Ural mountains. He was forced to remain inside the space capsule was inside until help arrives. Outside, the hungry wolf is waiting.
- Toilet
On May 5, 1961, astronaut Alan Shepard prefers to pee in my pants on the plane Freedom 7 that he was traveling. Andrew Chaikin, author describing the special outer space, travel in orbits so horrible.
He wrote that the toilet in space is shaped like a hat with a layer of packing tape on the edges. Astronauts need to apply or provide anti-bacterial coating after he was shitting.
Advice for the astronauts who had to meet the call of nature is: naked, prepare about one hour, and bring lots of Kleenex. Do it as soon as possible before the urine froze.
- Sudden decompression
Three of the astronauts Soyuz 11 died when the plane took off when air pressure will go back into the atmosphere. In 1965, a technician from the Johnson Space Center, Houston, USA managed to live and tell the similar experience.
When he was in a vacuum chamber, an accident happens and by accident, space costumes that he used to lose pressure. Before he lost consciousness, which he felt was the sensation he feels moist on the tongue feels like a boil.

Alien not a threat to Religion

 

Evidence of the existence of extraterrestrials (aliens), who delivered many experts, is no longer surprising people. No longer a man to panic. Why? The answer is that technology advances so quickly.

Leading psychologist, Dr Albert Harrison of the University of California Davis asserts that in 1961, the U.S. government has warned that evidence of the existence of aliens would create public panic.

But now the warning is no longer relevant. Modern man, says Harrison, it was happy or even the existence of aliens do not care if it's been proven. Advances in technology make the news about the alien is no longer scary.

"The discovery of ETI (extra-terrestrial intelligence) is not so surprising for a generation accustomed to the word-processing machines, electronic calculators, avatar and mobile phones," said Harrison as published in the journal Philosophical Transactions of the Royal Society.

Generation technologies, he added, "Unlike the generation that grew accompanied typewriter, rulers, slide rules, a public phone."

He added, people are already accustomed to the idea of ET since Alien seekers organization, the SETI (Search for Extra-Terrestrial Intelligence), claiming to hear an alien radio signals 50 years ago.

So terbisanya with aliens, half the population of the United States and Europe believe aliens do exist, and some even believe UFO sightings are reported to have anything to do with aliens coming to Earth.

The second article in the same journal written by Ted Peters, Pacific Lutheran theologian Theological Seminary in Berkeley, California.

In his article, Peters said, the discovery of aliens is not a threat to the world's religions.

This is based on a 1300 survey of different faiths around the world. "Clearly, the majority of religious adherents, regardless of what their religion, do not see contacts with space aliens as a threat to their beliefs."

Evolution expert Professor Simon Conway Morris of Cambridge University believes should. According to him, the possibility of human-like intelligent beings in outer space is very small.

If evolution occurs in every part of the universe, there can be no sky explorers who came from the older part of the universe.

"That does not happen, and will not happen. We never visited by aliens, and did not bother to make a welcoming committee for them." "They do not exist, and our own."

Toyota Prius is number one in the World

 

As we know, the bestseller in hybrid car is Toyota Prius. Despite success, Toyota Motor Corporation has not been satisfied, and even still have big ambitions. Japan's largest car manufacturer that wanted the Prius became the best-selling car of all product-Toyota, including the conventional engine-in the United States with a grace period until 2020.

Bob Carter, Toyota Group Vice President of U.S. Sales Division, said that, until now middle-Camry sedan is still a bestseller in America. But, the Prius wasbestseller in its segment, both Japan, U.S., and Europe.

"We will end this decade (2020) with the Prius to be number one in the industry (automotive U.S.). Camry will be shifted to a position two, but sales remained equally high, not a cannibal," Carter said, as reported by autonews (3 / 1 / 2011).

In the U.S., Toyota's Prius will complement variants starting from the current model (hatchback), a plug-in (in 2012) and the Station Wagon which will appear in the North American International Auto Show in Detroit, 10 January. Mike Michels, a spokesman for Toyota leaked, in addition to the three models, the company also presents an additional concept model without going to explain further.

Prius had strolled in the market "hybrid car" for 10 years and began to face competition from other manufacturers. End of 2010, Nissan Motor Company enliven the electric car market with Leaf and General Motors Company also released the Volt plug-in sedan.

The presence of new rivals to make the market "hybrid car" created greater.

Girl Found Supernova

 

A girl was 10 years old Canadian became the youngest inventor of a supernova or exploding star, according to the Royal Astronomical Association of Canada (RASC).

 Kathryn Aurora Gray of Fredericton in the eastern province of New Brunswick was found something rare in the last week as she combed dozens of imaging results in a telescopic star constellations in a galaxy far away.

"RASC is pleased to announce the discovery of a supernova by an amateur astronomer aged 10 years and thus became the youngest who can found supernova," the association said in a statement.

While observing a supernova in the constellation 2010lt camelopardalis stars in the galaxy, a distance of 240 light years from Earth, Gray immediately told his father who was an amateur astronomer named Paul.

The discovery was later proved by two American astronomers reported to the Board prior to the Joint Center for International Astronomy for Astronomical Telegrams.

Supernova are massive stars that run out of fuel and destroyed by the burden of its own gravity and become very dense objects called neutron stars.

Then they issued a shock wave that blew the star, and generate a vibrating radiation circle.

Outbreak was the most amazing phenomenon for astronomers and can be known when the powerful explosion created the dramatic lighting that eventually fade.
