Nasa beefs up its team of ‘alien hunters’ – and says we may be on the verge of finding extraterrestrial life.

Nasa claims we’ll find aliens in the next 10 to 20 years – and now the agency is revving up its efforts to track them down.

The group has put together a team of ‘extraterrestrial experts’ to see if any of the planets discovered outside our solar system are habitable.

And it says that the amateur astronomers could help with its ‘unprecedented’ search for ET by access research data online.

The initiative, dubbed Nexus for Exoplanet System Science (Nexss), will include scientists from 10 universities including Stanford, the University of California and Yale.

The study of exoplanets is a relatively new field with discovery of the first exoplanet around a star like our sun was made in 1995.

Since the launch of the Kepler space telescope six years ago, more than 1,000 exoplanets have been found, with thousands of additional candidates waiting to be confirmed.

Nasa has set up a website for the public called Planet Hunters which allows anyone to search the data gathered by Kepler, since launching six years ago.

Scientists are also developing new ways to confirm the habitability of these worlds and search for biosignatures, or signs of life.

By applying a ‘system science’ approach, the team hopes to understand on an alien planet’s biology interacts with the atmosphere, geology, oceans, and interior of a planet.

The announcement comes just weeks after Nasa’s top scientist predicted we could be on the verge of finding life on one of them.

During a talk in Washington last month, the space agency announced that humanity is likely to encounter extra-terrestrials within a decade.

THE NEXSS TEAM OF ‘ALIEN HUNTERS’: WHAT WILL THEY DO?

Alien hunters from the University of Berkeley, California and Stanford are tasked with answering the question: ‘What are the properties of exoplanetary systems, as they relate to their formation, evolution, and potential to harbour life?’ They will combine astronomical observations of exoplanets and forming planetary systems with powerful computer simulations and cutting-edge microscopic studies of meteorites. The team from Arizona State University in Phoenix will take a similar approach. This research group will place planetary habitability in a chemical context, with the goal of producing a ‘periodic table of planets.’ Researchers from Hampton University, Virginia, will be exploring the sources and sinks for volatiles on habitable worlds. This research will help determine the past and present habitability of Mars and even Venus. The team centered at Nasa’s Goddard Institute for Space Studies will investigate habitability on a more local scale. It will examine the habitability of solar system rocky planets through time. The team from Yale University in New Haven, Connecticut, will design new spectrometers – optical instruments that measure the spectrum of light – with the stability to reach Earth-detecting precision for nearby stars. A group led the University of Nebraska-Kearney will explore the existence and evolution of exospheres around exoplanets, the outer, ‘unbound’ portion of a planet’s atmosphere. From the University of California, Santa Cruz, a group will investigate how novel maths equations can be used to extract information from light that is emitted and reflected by planetary atmospheres.

‘I believe we are going to have strong indications of life beyond Earth in the next decade and definitive evidence in the next 10 to 20 years,’ Ellen Stofan, chief scientist for Nasa, said. 

‘We know where to look, we know how to look, and in most cases we have the technology.’

Jeffery Newmark, interim director of heliophysics at the agency, added: ‘It’s definitely not an if, it’s a when.’

‘We are not talking about little green men,’ Stofan said. ‘We are talking about little microbes.’

The announcement was prompted by the recent discovery of water by Nasa in surprising places.

Jim Green, director of planetary science at Nasa, noted that a recent study of the Martian atmosphere found 50 per cent of the planet’s northern hemisphere once had oceans a mile deep.

The same study found that water had been present on the red planet for up to 1.2 billion year.

‘We think that long period of time is necessary for life to get more complex,’ Stofan said.

Nasa associate administrator John Grunsfeld said he is excited about seeing what form life beyond Earth may take.

‘Once we get beyond Mars, which formed from the same stuff as Earth, the likelihood that life is similar to what we find on this planet is very low,’ he said.

‘I think we’re one generation away in our solar system, whether it’s on an icy moon or on Mars, and one generation [away] on a planet around a nearby star.

At the same conference last year, Nasa Administrator Charles Bolden made a more conservative estimate.

He claimed that we will find life within the next 20 years – with a high chance it will be outside our solar system.

Nasa next Mars rover, scheduled to launch in 2020, will search for signs of past life and bring samples for a possible return to Earth for analysis.

Nasa also hopes to land astronauts on Mars in the 2030s, which Stofan says is crucial key to the search for Mars life.

‘I’m a field geologist; I go out and break open rocks and look for fossils,’ Stofan said. ‘Those are hard to find.

‘So I have a bias that it’s eventually going to take humans on the surface of Mars — field geologists, astrobiologists, chemists — actually out there looking for that good evidence of life that we can bring back to Earth for all the scientists to argue about.’

The space agency is also planning a mission to Europa, which may launch as early as 2022. It hopes to find out whether the icy moon is habitable.

Meanwhile, the agency’s James Webb Space Telescope (JWST), will launch in 2018 to scope out the atmospheres of nearby ‘super-Earth’ alien planets.

    Why don’t they just go out to the top of a mountain or out in the desert at night and look up or through a modern version of light amplifying binoculars and see them visiting us ?? !!

    When they say they will find life in 10 to 20 years, that translates to “They will admit life exists in 10 to 20 years. As it is, they air brush all the craft out of their space photos so the public won’t see them.

    It should be obvious that NASA and SETI fear loseing all credibility in their stated aim of seeking evidence for the existance of extraterrestrial life, especially intelligent life (ETI) capable of sending technological signals; it is self interest that drives the official and academic debunkers and deniers of the ever presence of ETI visitors to earth in the form of UFO, UAP, since they would no longer be able to justify their inflated funding and unscientific ignorance on an insidious and massive scale of the overwhelming scientifically irrefutable and verified evidence, openly presented by numerous credentialled and trained observers of impecable qualifications – astronauts, pilots, police, security personnel, astronomers, scientists, credible people of all professions and in the general community, including five recent presidents of the USA, all of whom say they have been either denied access (on a need-to-know basis) to the secretly withheld UFO files, or at least are unable to even admit to the classified secrets’ existence. This state of affairs has recently surfaced into the public domain in the forum of the ‘Disclosure Project’, details of which are freely available online.

  • Peeping in on the gods! Remember they once lived on top of that mountain in Greece as I recall, Olympia. In my other life, I watched the games there on good days. Spook Ken.
