Life on Nearby Exoplanet Barnard's Star B Might Be Possible, According to Astronomers

Life on Nearby Exoplanet Barnard's Star B Might Be Possible, According to Astronomers Though it's freezing on its surface, primitive life might be lurking somewhere below.

A “ nearby ” Super - Earth planet has the potential for life to develop, astronomers announced Thursday. Scientists said that if water exists on the planet, geothermal Super - Earths are planets with masses larger than the Earth but not as big as the ice giants in our solar system, such as Neptune and Uranus.

Nasa announces discovery of seven Earth -sized exoplanets – video report. The discovery, which has thrilled astronomers, has raised hopes that the hunt for alien life beyond the solar system could start much sooner than previously thought, with the next generation of telescopes that are due to

Scientists said that if water exists on the planet, geothermal heating could create a subsurface ocean where primitive life might exist. The planet orbits Barnard’s Star, which is the second-nearest star system to the Earth.

The planet – known as Barnard b – is admittedly a bit on the nippy side at 274 degrees below zero. This means the planet would be ice-covered. But underneath the ice could be water “that provides niches for life," according to Villanova University astrophysicists Edward Guinan and Scott Engle.

Amateur scientists just found a new planet, and it might even be habitable

Amateur scientists just found a new planet, and it might even be habitable NASA's Kepler space telescope is dead. It ran out of fuel back in October of last year, but the incredible wealth of data that it sent back during its life is still being sifted through, and new discoveries are just waiting to be made. A timely reminder of that fact comes in the form of an all-new exoplanet discovery made by citizen scientists who dedicated their time to combing through Kepler’s logs. The world, called K2-288Bb, appears to be quite special, and researchers who have looked at the data think it might even host liquid water, raising the possibility that the newfound planet is habitable.

On 25 June 2013 Three " super Earth " planets have been found orbiting a nearby star at a distance where life in theory could exist, according to a record-breaking tally announced on Tuesday by the European Southern Observatory. " Scientists spot nearby ' super - Earth '".

Anglada-Escude was referring to Kapteyn b and its newly discovered sister "The detection of super - Earth mass planets around halo stars provides important insights into 1140 and the possible super - Earth planet which shows early indications of habitability.

The researchers' findings were presented Thursday at the annual meeting of the American Astronomical Society in Seattle.

The planet was discovered only two months ago.

Warmth from the planet's hot core could cause life to form in the planet's oceans, which would be underneath its ice-covered surface.

"We note that the surface temperature on Jupiter's icy moon Europa is similar to Barnard b, but because of tidal heating, Europa probably has liquid oceans under its icy surface," he said.

Super-Earths are planets with masses larger than the Earth but not as big as the ice giants in our solar system, such as Neptune and Uranus.

The planet and its star are nearby in cosmic terms only: At 30 trillion miles from Earth, Barnard's Star is the closest single star to our solar system. It's a barren, frigid world because light from Barnard's Star provides it with only 2 percent of the energy the Earth receives from the sun.

Alien signals? More bizarre 'fast radio bursts' detected from outer space

Alien signals? More bizarre 'fast radio bursts' detected from outer space More “fast radio bursts" – bright, short-lived pulses of radio waves that come from across the universe – have been detected by astronomers. The bursts, which originate from a distant galaxy that's 1.5 billion light years away from Earth, repeated 13 times, a new study reports. This is only the second time that repeating fast radio bursts have been discovered. “Until now, there was only one known repeating fast radio burst," said Ingrid Stairs, an astrophysicist at the University of British Columbia. "Knowing that there is another suggests that there could be more out there.

7 Earth -like planets could be best bet to find alien life . Astronomers call Trappist-1 the most incredible star system they've ever seen. On Wednesday, astronomers announced that the star, Trappist-1, is circled by at least seven Earth -sized planets, including three that could have oceans of liquid water to

The hunt for signs of life on seven nearby exoplanets will likely begin just a few years from now. Last year, a team of scientists and engineers announced the 0 million Breakthrough Starshot project, which aims to develop the Icy ' Super - Earth ' Exoplanet Spotted Around Nearby Barnard's Star.

Guinan said telescopes will need to continue peering at the planet. "Such observations will shed light on the nature of the planet's atmosphere, surface and potential habitability," he added.

Alien life possible on nearby 'Super-Earth,' scientists announce

The International Space Station will release its SpaceX cargo ship this weekend.
Both SpaceX and NASA are eager to get the Dragon cargo spacecraft back to Earth now that it has fulfilled its duties in bringing much-needed supplies to the crew aboard the International Space Station. The ship was originally expected to be released from the ISS earlier this week but plans have since changed, and NASA now expects the space station to bid farewell to the Dragon on Sunday afternoon instead. Prior to this latest change, the most recent schedule would have seen the ISS release the Dragon on Sunday morning, but now NASA says it wants to release it later due to some weather quirks back on Earth.
