Only a few star systems have more than one planet.
Our solar system has eight worlds and has long been the largest series. But no longer.
NASA and Google researchers announced Thursday that the corner of our galaxy now shares this record with another system, Kepler 90.
A Google algorithm found a planet 30% larger than Earth, orbiting a star thousands of light-years old. -years away.
The planet, Kepler 90i, brings the total number of planets orbiting its star to eight. -
It's like the octuplets in our solar system.
"We first discovered the eighth planet in a distant planetary system," Paul Hertz, head of NASA's Astrophysics department, said at a media briefing.
This discovery requires advanced technology to sort out the vast amounts of data acquired by the Kepler Space Observatory.
The Kepler Telescope, like a loyal puppy, has been observing space for millions of kilometers behind the Earth since 2009.
During that time, it brought data on 150,000 stars.
When an exoplanet passes in front of one of the planets, Kepler records a subtle drop in the star's sunlight.
Finding these data in massive databases is a challenge.
"The Kepler mission has too much data to be checked manually," explains Christopher Salu, an AI Software Engineer at Google in his briefing.
With the help of Andrew Vanderberg, an astronomer at the University of Texas at Austin, Sharon developed a machine. -
The learning procedure of detecting light curve. (
Google and NASA have worked together for many years.
In 2013, they launched the Quantum Artificial Intelligence Laboratory, a machine. -
Learning facilities at NASA's Ames Research Center. )
Scientists did not give this program, called a neural network, a clear indication of how to find the characteristic curves of exoplanets.
Instead, it must lead by example.
"Neural networks are inspired by the loosening structure of the human brain," Shallee said.
You can think of neurons as switches. " The U-
Kepler 90i passes through its star at such a weak tilt that it is impossible for humans to detect signals.
But it's powerful enough for AI to detect 14 billion data points.
Astronomers believe that the exoplanet exists and its surface temperature may exceed 426 degrees Celsius.
Its orbit is shorter than Mercury's, and it circles the stars every two weeks.
"It's almost certainly an exoplanet," Vanderberg said, with a false positive probability of 1/10,000.
The results of this deep data mining have been accepted and published in the Journal of Astronomy.
But the number of worlds is not the only similarity between our solar system and Kepler 90.
Like our planet, Kepler's rocky asteroid is nearest to the sun and farthest from it is its gas giant.
Kepler 90 itself is larger than our sun, though not very large.
However, planets in our system are more widely distributed.
Neptune is closest to 2.
Eight billion miles from the sun.
The farthest gas giant in Kepler 90 is 93 million miles from its star.
"All planets were found very close to their stars," Vanderberg said.
Because the telescope only observes the center of the system, it may contain other worlds.
Vanderberg added: "It's likely that Kepler 90 has more planets than we don't know about. "
Any planet with a longer orbit-
Leave Puller 90 Far as Jupiter is Far from the Sun-
It will pass through the observatory and not be found. (
On the other hand, some astronomers believe that our solar system may have unknown planets, such as Planet 9, lurking at the edge.
Maybe we can take back our Galactic Exceptionalism again. )
Kepler Telescope is in its twilight years.
In 2013, two of the four reaction wheels that maintained their target position failed.
If it is not solved, the task is doomed to failure.
Desperate to save $550-
With millions of spacecraft, researchers turned to the only available support: the sun.
They used the pressure of solar radiation to stabilize Kepler, as the Post reported in 2014.
With two functional wheels, the sun's power is like a crutch, and the spacecraft can focus again on distant stars.
The rebirth plan was named k2.
During the Kepler and K2 missions, astronomers confirmed the location of 2,500 exoplanets.
Kepler has detected another 5,000 exoplanet candidates awaiting confirmation.
The K2 mission received an additional three years of life support in 2016.
Fuel for the spacecraft is expected to dry up sometime in 2018.
