NASA has
discovered a planet which could be the largest planet in the solar system. It is considered to be the eighth planet in the family of solar system. The research in space is exponentially growing with
the development of the technologies. Likewise, NASA with the help of Google’s
Artificial Intelligence made the discovery of the planet.
AI found the planet
by scouring the weak signals in data captured by Kepler telescope. The newly
found planet is said to be located in the solar system around Kepler-90, a star
which is about 2500 light years away from the earth that was previously
discovered in 2014.
Since 2009, the Kepler Space Telescope has been
searching for the planets outside the solar system (exoplanets). The scientists
took the strongest signals first to go through the datas that has been
collected by the Kepler since its launch. These collection of datas make scientists
to understand or to find the planets around the stars that make up our galaxy.
Artificial Intelligence is now became a most
prominent tool in the field of astronomy in recent times. The scientists now
are increasingly turning to machine learning, to help sort through typically
lower priority missing data.
The planet is named as Kepler-90i. Kepler-90 is
about 20 percent bigger and 5 percent warmer than the sun. The orbits are so
comparatively small that seven of Kepler-90’s eight planets would
fit in between the Earth and the Sun.
The discovery of Kepler-90i,
came after NASA let Google train its machine learning algorithms on 15,000
signals from potential planets in the Kepler database.
The scientists worked on about 670 stars as they are considered to be the most
likely hiding places.
According to Chris Shallue,
a senior Google AI software engineer who worked on the project said the
inclusion of machine learning in this process shouldn’t scare humans whose
livelihood revolves around discovering and studying exoplanets.
“What we’ve developed here
is a tool to help astronomers have more impact. It’s a way to increase the
productivity of astronomers. It certainly won’t replace them at all.”
“This is really
exciting discovery and a successful proof of concept in using neural networks
to find planets even in challenging situations where signals are very weak.
“We plan to search
all 150,000 stars, we hope using our technique we will be able to find lots of
planets including planets like Earth.”
The discovery is important because it takes the number
of planets in the star system up to eight, the same as our own Solar System. It
is the first time that any system has been found to have as many planets ours.
