If aliens really visit the Earth, who will greet those guests? Do not worry, the United Nations has set a candidate. She is an astrophysicist Mazi Lan Osman, Malaysia.

According to the British “Daily Mail” reported on 26th, the United Nations Office for Outer Space Affairs will be assigned person in charge, 59-year-old Osman was the first alien planet approached the Commissioner, specifically exposure to aliens who may visit Earth.

Osman next week in the British Royal Society scientific meeting held in the Conference Centre describes her scientific discoveries, to the delegates attending the meeting that she found the planet from a few hundred signs of extraterrestrial life forms.

Recently, the Office for Outer Space Affairs Uthman, scientists say, humans need to plan ahead, make contact with alien life preparation. In addition, the introduction of this work, the United Nations must coordinate the public “first received” response. Osman said: “The agency conducted by a number of alien activity has been exchange of people keep searching for hope, someday, humans will receive signals from alien life. When that moment comes, we should set up a coordinating body responsible for all associated with this sensitive transaction. while the United Nations is such a coordinating body ready. ”

According to “Science Daily” network recently reported that a U.S. research team used a high-sensitivity camera, on the planets around distant stars the size of the operation carried out accurate measurements. High sensitivity of this camera can be detected in the 1,000 meters outside the moths from the bright window through the moment.

The camera by the Astronomical Institute of the University of Hawaii John • Tom Swiss design, and was named Orthogonal Parallel Transfer Imaging Camera (OPTIC). OPTIC using a new type of detector, such orthogonal parallel arrays in the world’s largest digital camera Pan-STARRS (Panoramic Search Telescope and Rapid Response System) also have applied. This detector and CCD (charge-coupled device) similar, but the new detector is more stable and can collect more light, so that more accurate measurement. This optical measurement precision than the ordinary CCD 3 times to 4 times higher than the best CCD have 2 times to 3 times higher, with the Hubble Space Telescope on the shooting stars with brightness comparable.

The camera was installed in the Hawaii Monakea mountain UH2.2 meter telescope, used to measure the planet around the star through the front of the fine occurs when the brightness decreased. This “planetary transit” process allows researchers to objects outside the solar system to measure the radius. Johnson explained: “We know that the Milky Way in more than 330 planets around other stars are in the running, but just after that we can only measure the physical size of the stars of the planet.”

The research team’s study, called WASP-10b, which operate around the star WASP-10, the star about 300 light years from Earth. Schools that WASP-10b has a diameter large, but the scientists to more accurate measurement of the diameter obtained after the new findings: WASP-10b is not one of the largest volume of the planet, but so far the densest planet known one.

Experts said this is the first time on Earth-sized planets in the “transit” to the accurate measurement, this new type of detector will really change the existing planetary analysis method. OPTIC high accuracy, the accuracy of measurement of light up to 1 / 2000, can detect more asteroids “transit” process.

The movie “2012″ brings us to the end of the world’s infinite imagination, if the human face extinction on Earth, how can we do? Someone is really deep in Tibet as the construction of Noah’s Ark it? We are not aware of this, but scientists are planning to build on the moon ark carrying the end of human civilization.

Last month, scientists at the meeting in Strasbourg, France, discussed the concept of the lunar architecture database, the database will provide survivors on Earth to provide a reconstruction of human civilization, the remote access kit. “Doomsday Ark” is the most original version of the moon to build a repository of human knowledge bearer, including the DNA sequence, metallurgy shows that cultivated crops in the knowledge that the moon will be buried deep underground in a cellar, the signal transmitter would continuously send its location to Earth.

To avoid this database on the moon by the radiation and extreme temperature vacuum environment, it was buried under the rock, and has a solar panel to provide it with some energy. Scientists hope that by the year 2020 put the first batch of experimental data on the moon save, save its life span is 30 years, complete data on human civilization will be officially launched in 2035, this information will include Arabic, Chinese, English, French, Russian and Spanish versions.

Like how? The grand plan enough, right? If you would like to participate, to the time you can put your things are kept in the moon above.

New Hubble images show galaxy shooting a neighbor in the Large Magellanic Cloud there is a mysterious pink “brain-like” nebulae, the fluffy clouds dotted with many shining bright star. Nebula age of the oldest stars are only one thousandth of the sun.

Pink “brain-like” nebula known as the “LHA 120-N 11B”, referred to as N11B nebula, which is nurtured by a huge cloud of gas form stars, its mass is 10 times the sun. N11B Nebula in the bottom right of the existence of dozens of bright blue stars, which is a new birth of supermassive stars. These hot stars to the release of the UV space, and a strong jet from the stellar surface, the gas flow. The role of these stars, its surrounding material is heated under compression conditions.

N11B Nebula in the upper left is a frontal structure, which is formed when the shock wave moving through the gas, if the gas reaches a certain density, will collapse and form more stars.

N11B Nebula in the top left is a star, it is the image of the brightest stars, so it’s temperature, light intensity, quality, and the corresponding wind strength is maximum in the star hierarchy. The right side of the star is more cosmic gas, it is likely that the residual gas during star formation.

Another spectacular sight is located in the bottom left image, one can see dark spots on the structure, they are dead in the star formation regions in the mixture of dust, the mysterious elements of the dense gas cloud complex. Here is the exact star formation regions, the formation of the gas cloud is brewing a new star.

So astronomers surprise, they found that the brain Nebula contains three different periods of the stars. Some groups like the star is the youngest, a large number of middle-aged and those stars that only millions of years of history, the oldest stars in the nebula is only one thousandth of the solar age.
