Tenaga Misterius Antariksa Bingungkan NASA

A NASA satellite which was launched 30 years ago, has been influenced by a mysterious force. This phenomenon is able to change the laws of physics.

Scientists from the National Aeronautics and Space Administration (NASA) said Pioneer 10 satellites that take pictures of Jupiter before leaving the solar system in 1983, has now pulled back to the sun by an unknown force.

However, this incident does not give effect weakening energy spacecraft in space travel. Scientists are even considering the possibility of an investigation about a new force of nature.

NASA research team member Dr. Philip Laing said his team has examined the entire system based on existing theory. However, there is no acceptable explanation. "If this effect is real, the emerging theory will have a major impact on the system of cosmology and spacecraft navigation," said Laing.

NASA's Pioneer 10 was launched on March 2, 1972. Kembarannnya besama with the Pioneer 11, the two satellites is revolutionizing the science of astronomy by presenting a detailed picture of Jupiter and Saturn.

Scientists initially suspected that the gas emerging from the rocket motor on board small satellites, has been leaked thus generate nuclear power. However, this theory has been ruled out.

They could not find an explanation about the existence of constant strength, good understanding of the effects of gravity and solar radiation, which triggers rapid decline with distance.

This strange behavior also eliminates the possibility that the two aircraft are being influenced by the gravitational pull of planets that are not known outside the solar system.

Space scientist at Salford University Dr. Duncan Steel says likely theory about the weak force, which proved to have a big impact on a cosmic scale. "This may be the reason why the comet appears to earth millions of years ago. We might have questions about the law of gravity, "he said

London-Society seems to be prepared for floods, droughts and rising sea levels. This is because the Government was unable to stop global warming.

It is revealed the British Environment Minister, Caroline Spelman. According to him, the last few years, the British government's policy of concentrating its efforts on reducing carbon emissions by saving electricity and socialization own vegetable production.

However, greenhouse gases continue to increase globally in fact. Climate change increases the consequent high growth developing countries, like China and India that use energy so big.

British government will soon make plans to keep the source of electrical power from the flood and ensure the hospital can function well, concerning the availability of water in the dry season.

Since the beginning of the industrial era, the earth temperature has risen 0.8 degrees Celsius.

Temperatures are expected to continue to increase, because greenhouse gases have been 'locked', though takes time to warm the atmosphere.

He also stressed the importance of working hard to reduce greenhouse gas emissions, so the problem does not get worse. "But we've stuck with the problem of temperature change that can not be avoided.

Therefore, we must prepare the best and worst scenarios, rather than saving the planet. "

However, some observers worry about the environment of this statement. They feared the plan would reduce government funding for save earth

Jakarta-large disaster that caused the death of a giant species of mammals, including mammoths, large-toothed tiger and giant beaver was not a comet impact.

Previous researchers mentioned that mass extinctions occurred on Earth due to the comet hit the earth. The collision triggers a very drastic drop in temperature of about 13 thousand years ago. Abrupt climate change known as the Younger-Dryas temperature reversal was seen as a cause of extinction of most mammals, and human ancestors.

However, scientists at Washington University, Missouri, and Royal Hollway, University of London, found that the crystalline carbon is not the whole lump of facts from the element carbon, known as graphene which is usually in the form of sediment.

Professor Andrew Scott, one of the writers in the department of earth sciences Royal Holloway University, said, "Our results dubious one last piece of the widely discussed hypothesis regarding the impact-Younger Dryas."

Scientists deny the controversial theory that after finding a key piece of evidence used to support the idea of a comet impact probably created by a more mundane process.

This theory is based on fresh water from a giant glacial lakes glaciers in the North Atlantic where ocean currents have helped keep most of the ice planet. It becomes the most likely explanation about climate change that triggered the extinction.

Humans also spread to North America. However, after the climate change which suddenly triggered the last ice age, many of these species are already extinct and the number of people estimated to decrease to only a few thousand people.

Three years ago, scientists at the University of Oregon found evidence of exotic materials, including nano-diamonds in the 12 900-year-old sediments are considered as the impact of the comet that crashed into the earth.

However, Scott and Tyrone Daulton professor from Washington University, said that diamonds are misunderstood because they did not find evidence about the collision of comet.

Dr. Douglas Kennett who led a team from the University of Oregon says that scientists previously have been looking in the wrong place.

"Claims based on diamonds before the wrong address, incorrect and misdirected," says Kennett

NASA Lakukan Misi Ambius ke Matahari

NASA developed an ambitious mission to launch a car-sized satellite into the atmosphere of the sun, where there has never been another plane to where it was before.

This spacecraft is called Solar Probe Plus slides are planned before 2018, NASA said on Thursday.

Institution has selected five space science experiments along these spacecraft that will explore the sun. Instruments including the solar wind particle detector, 3D camera and a solar magnetic field measuring device.

"This project allows human ingenuity where previously there was no plane that went into the sun," said program scientist of NASA Solar Probe Plus, Lika Guhathakurta in a statement.

"For the first time, we can touch, feel and smell a rat the sun."

Solar Probe Plus when approaching the sun, this satellite will encounter temperatures exceeding 2550 degrees Fahrenheit (1399 degrees Celsius) and a strong blast of radiation.

This spacecraft is expected to gain what has not been obtained previously. Seeing stars closer to allow scientists to better understand the radiation environment to characterize and forecast for future explorers, NASA officials said.

Jakarta-Scientists at the Big Bear Solar Observatory using adaptive optics instrument is able to catch the point of the sun (sunspot) most clearly throughout history.

A photograph produced by the New Solar Telescope (NST) belonging to Big Bear.

NST is part of a very large telescope Advanced Technology Solar Telescope (ATST) will be prepared several decades into the future.

Big Bear ambitious scientists to build an adaptive optics system or better known as multi-conjugate adaptive optics. This tool can give a very clear observation without distortion (interference) from the sun from the earth's surface.

Therefore, the NST would be able to collect amazing picture detail, the phenomenon of the sun for example. These capabilities help scientists understand the complexity of the solar system, and its impact with the change of weather in the solar system.
