Nasa to make 'major' alien-hunting Kepler discovery
- Nasa will hold a briefing on Thursday December 14 to reveal new Kepler results
- The probe's latest find was made using artificial intelligence from Google
- The Kepler mission has spotted thousands of exoplanets since it launched
- The telescope's results help Nasa guide its search for alien life
Nasa is set to make a 'major' announcement in its hunt for alien life on Thursday.
Very few details have been revealed about the briefing this week, which will take place via teleconference on at 1:00pm ET (6:00pm GMT).
However, Nasa says the news will focus on work done by its Kepler planet hunting telescope which has been working with Google's AI system to find potentially-habitable worlds.
The Kepler mission has spotted thousands of exoplanets since 2014, with 21 Earth-sized planets now known to orbit within the habitable zones of their stars.
The briefing is likely to reveals the telescope's latest catalogue, which is set to be Nasa's best look yet at possible alien planets.

Nasa is set to announce a major discovery made by its planet-hunting Kepler space telescope (artist's impression) this week, in an event that could help guide the search for alien life. The probe's latest discovery was made by researchers using artificial intelligence from Google
The teleconference on December 14, and will be live-streamed on Nasa's website.
'The discovery was made by researchers using machine learning from Google,' Nasa said.
'Machine learning is an approach to artificial intelligence, and demonstrates new ways of analysing Kepler data.'
Scientists from the Astrophysics Division of Nasa's Science Mission Directorate and Ames Research Centre, as well as a senior Google AI software engineer and an expert from the University of Texas at Austin, will reveal the latest planet candidate results at this week's event.
The Kepler space telescope launched in 2009 and has since helped in the search for planets outside of the solar system that orbit within the habitable zone of their star.
Last summer, astronomers revealed they'd discovered 197 new planet candidates, and confirmed 104 planets through the Kepler mission.
The planets, which are all between 20 and 50 per cent larger than Earth by diameter, orbit the M dwarf star K2-72, found 181 light years away.
At the time, the researchers, led by the University of Arizona, said the possibility of life on planets around a star of this kind cannot be ruled out.
Since its launch, the Kepler mission has been plagued by several setbacks, but has continued to spot new objects outside of the solar system.
As of May 2014, Kepler started its K2 mission, which has provided an ecliptic field of view with greater opportunities for Earth-based observatories in both the northern and southern hemispheres
The Kepler mission has spotted thousands of confirmed exoplanets over the years, with 21 planets not much larger than Earth now known to orbit within their stars' habitable zones
In its initial mission, Kepler surveyed just one patch of sky in the northern hemisphere, measuring the frequency of planets whose size and temperature might be similar to Earth orbiting stars similar to our sun.
In the spacecraft's extended mission in 2013, it lost its ability to precisely stare at its original target area, but a fix created a second life for the telescope.
After the fix, Kepler started its K2 mission in 2014, which has provided an ecliptic field of view with greater opportunities for Earth-based observatories in both the northern and southern hemispheres.
Because it covers more of the sky, the K2 mission is capable of observing a larger fraction of cooler, smaller, red-dwarf type stars.
