The Space Agency (NASA) has confirmed the discovery of 1,284 new alien planets and based on calculations; researchers believe there could be TENS OF BILLIONS of habitable planets in the Milky Way Galaxy alone.

Scientists have also discovered that Earth’s ‘twin’ planet may be found just 11 light years away from our Sun. In the recent list of planets, around 550 could be strong rocky planets like Earth.

The National Aeronautics and Space Administration (NASA) has confirmed the discovery of 1,284 new planets, total number of planets discovered by the Kepler mission are 2,325 confirmed extra-solar planets. This discovery means we have doubled the number of exo-planets whose presence has been confirmed by astrophysicists. Many scientists say that nine of those planets are measured as possibly habitable.

‘This gives us faith that somewhere out there in the universe, around a star much like Sun, we can sooner or later discover another Earth,’ said Ellen Stofan, chief scientist at NASA.

The discovery itself is a massive development not only because it doubles the number of confirmed alien planets in the cosmos, but because it is the largest number of exo-planets revealed at one time.

The finding way made thanks to a different technique that lets researchers to evaluate the probability that blips in the data really are planets and not the effect of other natural objects. Kepler measures the intensity and brightness of a star like an electrocardiogram: when a planet travels in front of it, measurements aboard the spacecraft make a small pulse that astrophysicists investigate in order to confirm the existence and size and orbit of the cosmic body.

According to Dr. Natalie Batalha, calculations point that the Milky Way galaxy could contain tens of billions of habitable planets alone.

‘If you question yourself where is the next habitable planet expected to be, it’s contained by about 11 light-years, which is very very close,’ she told the BBC.

The results were attained after the Kepler space telescope’s July 2015 planet candidate list was studied, finally leading to the finding of the 1,284 planets. The recently discovered cosmic objects were given the rank of a planet since the chance of them being a planet is greater than 99%, which is considered as the minimum condition. Allowing astrophysicists, to add 1,327 more candidates possibly than not to be actually planets, but they do not meet the 99% threshold.

‘Before the Kepler Space Telescope launched, we didn’t know whether exoplanets were uncommon or common in the Milky Way galaxy,’ said Paul Hertz, Astrophysics Division director at Nasa Headquarters

‘Thanks to Kepler and the exploration community, we now see there could be more planets than stars.’

Timothy Morton, subordinate research scholar at Princeton University (PU) in New Jersey and main author of the exploration published in The Astrophysical Journal used a new technique to discover planets without any addition required.

“Imagine planet candidates as bread specks,” Timothy Morton, who established the new technique, said in a live press meeting. “If we fall a few on the ground we can pick them in the hands one by one. But if you drop a whole bucket packed with small crumbs, you might need a broom to clean them up.”

Morton’s model works by examining and calculating two important things: how much the figure (shape) of a candidate planet’s transfer signal looks like a planet, statistically speaking; and moreover, how rare false positives ‘imposter candidates’ are out there in universe. When scientists put this data together, they achieve a reliability score in the middle of zero and one for every candidate planet. Candidates with reliability more than 99% are known as ‘validated planets.’

Fascinatingly, Morton’s calculation matched up without a glitch with what telescopes had sighted.

“For each planet that the ground-based studies measure to be a planet, I expect it should be a planet,” Morton said, “and all they measure to be a false positive, I guess to be a false positive.”
