Two new planets orbiting distant suns

Two new planets orbiting distant suns”

Our solar system is not alone atop the planet-harboring heap anymore.

Suzanne Aigrain, an astrophysicist at Oxford University who was not involved with the research, said: "What is perhaps most exciting is that they are able to find planets that were previously missed, suggesting there are more yet to be found using this approach".

NASA's discovery of the new planet comes with help of some fancy artificial intelligence by Google.

But the agency only holds such events for significant breakthroughs, leading to speculation about what the Kepler space telescope might have found.

Searching for planets with more distant orbits is hard because potential transit signals happen less frequently.

This planet-hunting work has been incredibly successful. As for now, scientists have discovered an eighth planet known as Kepler-90i which is revolving around the solar system of the star Kepler-90.

Kepler-80g was found in the planetary system around Kepler 80. They intend to feed their neural network the complete data set, which includes 150,000 stars. "Machine learning really shines in situations where there is so much data that humans can't search it for themselves". This made it possible for the team to examine 670 systems known to have multiple exoplanets on the assumption that these systems were most likely to show weak light curves of further planets.

'For the first time since our solar system planets were discovered thousands of years ago, we know for sure that our solar system is not the sole record holder for the most planets, ' said astronomer Andrew Vanderburg. This discovery demonstrates the diversity of planetary systems, said Jessie Dotson, Kepler project scientist at NASA's Ames Research Center in California's Silicon Valley.

And they found two such planets, including Kepler-90i, which lies about 2,545 light-years from Earth.

Like Earth, this new planet, Keplar-90i, is the third rock from its sun. "You have small planets inside and big planets outside, but everything is scrunched in much closer", Vanderburg said. Will we see more candidates emerge from the data as well, as the AI sees patterns that were lost to our other methods?

The newfound world orbits a star named Kepler 90 which is larger and hotter than the sun and lies 2,500 light years from Earth in the constellation of Draco.

These planets may have migrated inward, toward their host star, over time, they added. But the current configuration, odd as it may seem to us, appears to be relatively stable, Vanderburg said.

Researchers had known that seven planets were orbiting the star.

Vanderburg said the got lots of false positives of planets, but also more potential real ones too. It also rotates Kepler 90 in just 14 days, vs. the 365 day cycle for Earth around the sun.

We can't claim our solar system is unique anymore.

What's perhaps even more remarkable is that just by looking at this data scientists can determine its size, distance from the star and even some basic information about its composition and atmosphere. "I hope it may give people more of a reason to go into astronomy to use more advanced technology like this".
