Latest is now that China’s Antarctic Astronomy Base, is in active search for Alien l. Why all of a sudden this interest for Alien life is yet unknown.
Chinese astronomers are actively searching for Earth-like planets using survey instruments in Antarctica, as they believe efforts to seek an extra-solar planet that harbours life will soon be rewarded. “It’s highly possible that human beings might find such a planet in the coming few years,” said Wang Lifan, director of the Chinese Centre for Antarctic Astronomy. “Such planets likely exist in the Milky Way, with a possible distance of thousands of light years from us.”
Chinese astronomers installed the first of three Antarctic Survey Telescopes (AST3-1) at Dome Argus, located at the highest elevation on the Antarctic continent, at the beginning of the year. One of its primary missions is to search for extra-solar planets suitable for life.
“Antarctica has the best conditions on Earth for astronomical observation, as it has very flat ground, a transparent atmosphere and little turbulence. The ground-based telescopes here will bring us precious information from the universe,” he said. “We will send people there to retrieve observation data next spring. I hope we can find some likely candidates. It’s hard to say precisely how many, but I hope there are no less than 10,” Wang said.
Chinese astronomers now rely on an Iridium satellite phone to give orders to and receive data from their survey instruments in Antarctica, which only allows them to send and receive a small amount of data at a time. Wang revealed that his team is considering building a supercomputer system in Antarctica.
“The new system could help us analyse the massive amounts of data gathered at the site and transmit small amounts of processed data back via satellite.” “So far, humans have yet to find an exact twin of the Earth,” Wang said.
“We search through a wide range of main sequence stars, mainly sun-like stars, and then look for planets within a suitable distance around them. Stars that are smaller and darker than the sun, such as dwarfs, are also in our survey scope,” he said.”If the stars are particularly large, they are inclined to evolve faster. Some will explode soon, and their planets will go missing after the explosion.”
“We know too little about life. Maybe there are new forms of life that do not need exactly the same environment as we have on Earth. Some can survive in very harsh environments,” Wang said.
The second AST3 will be installed in Antarctica between late 2013 and early 2014, while the third one will be installed between late 2014 and early 2015. “These telescopes are expected to help us find at least 100 sun-like stars. We will work with Australian scientists to further study the movement of the stars to calculate their size,” Wang said. Chinese scientists are also planning to set up an Antarctic observatory to further boost their research and broaden the search for habitable planets. If approved and included in the 12th Five-Year Plan, the observatory should go into operation by 2020.
Search for alien life gets boost from twin stars
And China`s search for Alien life now gets a boost from two twin stars. The universe is looking increasingly crowded as scientists announced the first proof twin stars can host multiple planets — boosting their search for a planet that could support life.
“We’re seeing more and more planets in more and more situations,” Jerome Orosz, an astronomer at San Diego State University, told AFP. “We’re almost to the point where you look at a star and say why doesn’t this have a planet?” he added.
Orosz is part of a team that has observed at least two planets orbiting around a pair of stars that are also orbiting each other. It’s a potentially chaotic arrangement — with shifting gravity depending on where the stars are that scientists weren’t sure was possible.
Maybe we all get to see a real EBE sometimes?
The newly discovered planets were found around Kepler-47, a Sun-sized orb paired with another about a third as big. NASA’s Kepler telescope — searching through the universe for as many worlds as it can find — has already found bodies at four other twin stars. But this is the first time astronomers have proof of more than one planet at a time. And just maybe there’s a third planet in there as well, Orosz said, though they still need more data. The planets are gas giants, around the size of Neptune. But these two are orbiting very close to their suns. In fact, the outer planet is hanging out within that sweet spot scientists call the “habitable zone” — not too close and hot, not too far and cold.
“After a star forms, it’s got a little bit of leftover material,” Orosz explained, “which eventually forms the Earth and the planets.”
“The question was, if you put the disk and debris around a binary (star), would it survive long enough to form planets? And the answer is yes.”
That’s a first, too, and an exciting one, because it’s another step towards finding an Earth-size planet within that zone, somewhere out there.
“Now we can find planets in these sorts of orbits. So the next step is to look for smaller and smaller bodies,” Orosz explained, something that becomes easier as more data accumulates.
“If you go out at night and look at the sky, roughly half the stars you see are binary stars,” Orosz said.
“So the fact that you can find planets in the habitable zone of binary stars means you have lot more real estate” for potential life.
With Orosz as lead author, the team presented its findings in the magazine “Science.”
