NASA to hold press conference to reveal latest discovery THIS WEEK

NASA could be on the verge of an alien breakthrough after calling a press conference to unveil a major new discovery.

By Thomas Mackie
Published: Sun, Dec 10, 2017

The space agency will hold a press conference on Thursday to reveal its latest major discovery after searching outside of our solar system for life by scanning habitable planets.

The new discovery comes from the team at the Kepler space telescope, who have been searching for extraterrestrial life since 2009.

The telescope searches for Earth-sized planets in the “habitable zones” of nearby stars and has subsequently found thousands of planets which could hold life.

NASA officials said: "The discovery was made by researchers using machine learning from Google.

"Machine learning is an approach to artificial intelligence, and demonstrates new ways of analyzing Kepler data."

The Kepler space telescope spots alien worlds by noticing the tiny brightness dips they cause when they cross the face of their host star from the spacecraft's perspective.

Kepler has become the most successful planet hunter in history.

The telescope has found 2,500 alien worlds, which is around 70 per cent of all known exoplanets.

The vast majority of these discoveries have come from observations that Kepler made during its original mission, which ran from 2009 to 2013.

Over the past few years, researchers have used improved analysis techniques to spot many exoplanets in data that Kepler gathered half-a-decade ago.

Kepler’s first mission, which ended in May 2013, involved observing around 150,000 stars.

The mission ended when the spacecraft lost its second orientation-maintaining "reaction wheel," which allows it to be directed towards stars.

Kepler is now on its second mission, called K2, where it is in search for exoplanets on a more limited basis.

Last year, NASA announced the discovery of nine planets orbiting the star TRAPPIST-1.

Three of the planets were believed to be in the star’s habitable zone and capable of harbouring life.

A spokesman for NASA said: "The latest Kepler catalogue of planet candidates was created using the most sophisticated analyses yet, yielding the most complete and reliable accounting of distant worlds to date.

"This survey will enable new lines of research in exoplanet study, which looks at planets outside our solar system.”

Ask us about NASA's planet-hunting Kepler space telescope’s latest discovery, which was made using machine learning from Google. Machine learning is an approach to artificial intelligence, and demonstrates new ways of analyzing Kepler data.

Please post your questions here. We'll be online from 12:00-1:30 pm PT (3:00-4:30 pm ET, 20:00-21:30 UTC), and will sign our answers. Ask us anything!

• Kartik Sheth, program scientist, Astrophysics Division at NASA Headquarters in Washington


UPDATE (10:44 am PT): Today, December 14, 2017, researchers announced our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light years from Earth. The planet was discovered in data from NASA’s Kepler space telescope. For more info about the discovery, visit https://www.nasa.gov/press-release/artificial-intelligence-and-nasa-data-used-to-discover-eighth-planet-circling-distant

The newly-discovered Kepler-90i --a sizzling hot, rocky planet that orbits its star once every 14.4 days -- was found using machine learning from Google. Machine learning is an approach to artificial intelligence in which computers “learn.” In this case, computers learned to identify planets by finding in Kepler data instances where the telescope recorded signals from planets beyond our solar system, known as exoplanets.

The discovery came about after researchers Andrew Vanderburg and Christopher Shallue trained a computer to learn how to identify exoplanets in the light readings recorded by Kepler – the miniscule change in brightness captured when a planet passed in front of, or transited, a star. Inspired by the way neurons connect in the human brain, this artificial “neural network” sifted through Kepler data and found weak transit signals from a previously-missed eighth planet orbiting Kepler-90, in the constellation Draco.

We’ll be back to answer your questions at 12 pm PT. Ask us anything!

First solar system like ours with eight planets discovered

NASA today announced it has found another solar system just like ours with EIGHT planets... boosting the chances of finding ALIEN life elsewhere in the Universe.

By Jon Austin
Published: Thu, Dec 14, 2017

The historic discovery was made by new scientific analysis of data obtained by the Kepler space telescope, which is scouring the galaxy for planets like Earth.

Paul Hertz, Astrophysics Division director at NASA Headquarters in Washington, said: "We have found for the first time an eigth planet in a distant planetary system in the Kepler 90 system - this ties Kepler 90 with own solar system for having the most known planets.

"Kepler 90 is the first star to host as many planets as our own."

The new planet - Kepler 90i - is a small rocky planet, but very close to the sun which is hotter than ours, and is 2,500 light years from Earth.

It would be scorching hot and unable to hold life itself, although some planets in the system may be able to.

But, it means that NASA now believes most stars in space are likely to have a series of planets orbiting, boosting the chances of there being more like Earth with the conditions for life to evolve.

For life to form, it is believed that a planet must be rocky, and at the right distance from its star to be not too hot or cold, so it can hold liquid water and an atmosphere.

A team of NASA scientists who have scoured the universe looking for planets that could potentially hold alien life today made the historic announcement in a briefing at 6pm British time.

It was to unveil the latest findings of the Kepler space telescope mission.

Kepler 90i orbits its home star every 14 days and is about 30 percent bigger than Earth.

The planets in the Kepler 90 system orbit much closer to their host star than Earth is to the sun.

Andrew Vanderburg, astronomer and NASA Sagan Postdoctoral Fellow at The University of Texas, Austin, said: "The Kepler-90 star system is like a mini version of our solar system. You have small planets inside and big planets outside, but everything is scrunched in much closer.

"Kepler 90i is about 2,500 light years away in the northern sky.

"It is the smallest of a bunch of probably rocky planets, not with thick atomosheres like the gas giants further out.

"But, I would not like to visit, it would have a surface temperature of about 800 degrees fahrenheit, the surface would be scorching hot.

"Kepler 90 is the first exoplanet system like ours with eight planets, but I think it won’t be the last.

"Our solar system is not sole record holder for solar systems with the most planets and we have just scratched the surface. There might be more out there that make our eight look small."

Kepler-90i wasn’t the only new planet found by the machine learning system.

In the separate Kepler-80 solar system, thought to have five planets, was a sixth.

NASA says the new discovery has been made by researchers using machine learning from Google, which is an approach to artificial intelligence, and demonstrates new ways of analysing Kepler data.

The Kepler telescope recently found ten more planets outside our solar system which could be the size and temperature to support life.

A Nasa researcher hinted that aliens could be out there somewhere.

Kepler scientist Mario Perez said: “We are probably not alone.”

A NASA spokesman said: "When Kepler launched in March 2009, scientists didn’t know how common planets were beyond our solar system.

"Thanks to Kepler’s treasure trove of discoveries, astronomers now believe there may be at least one planet orbiting every star in the sky."

Kepler completed its prime mission in 2012 and went on to collect data for an additional year in an extended mission.

In 2014, the spacecraft began a new extended mission called K2, which continues the search for planets outside our solar system, known as exoplanets, while introducing new research opportunities to study young stars, supernovae and other cosmic phenomena.
