NASA discovers 301 new planets on ExoPlanet with the ExoMiner program – archyde

JAKARTA – Scientists believe the Milky Way galaxy is home to billions of planets. In an endless quest to unravel it, more than 300 new discoveries have just been added to NASA’s official list.

This solar system is approximately 287.46 billion kilometers in diameter and is home to eight planets (including Earth). It sounds like a lot, but our solar system is a tiny point compared to the entire universe – and even compared to the Milky Way.

The Milky Way (our home galaxy) is estimated to be home to 100,000 million stars and at least 100 billion planets. From there, the Milky Way is just one galaxy in a sea of ​​hundreds of billions of galaxies in the known universe. This type of scale is very elusive, but scientists and astronomers are constantly trying to understand it better.

That’s what makes this latest announcement from NASA so exciting. To date, NASA has discovered 4,569 planets outside of our solar system but inside the Milky Way (also known as “exoplanets”).

On November 22nd, NASA confirmed that it had just added 301 new exoplanets to the list at one time. This is an achievement that sounds impossible, but it works straight out of science fiction thanks to advanced neural network technology.

Scientists have developed several methods of finding exoplanets, one of which revolves around studying stars. If the star darkens slightly as you observe it, it is likely because a planet is orbiting it. It is a proven method of determining the size and orbits of potential planets, but the number of possible stars studied is too many for humans to handle on their own. This is where NASA’s “ExoMiner” program comes into play.

ExoMiner is a deep neural network developed by NASA to examine potential exoplanet data and determine whether it is a true or false positive result. ExoMiner is trained on proven discovery methods and “properties that human experts use to confirm new exoplanets”.

It takes that information, gets smarter by checking previously confirmed exoplanets, and uses all of this information to identify new exoplanets at a rate no human can match.

With ExoMiner, along with people who are “professionals at combing data and analyzing what exists and not planets,” NASA has made over 300 discoveries as if it were nothing.

All 301 exoplanets confirmed by ExoMiner were first discovered by Keppler and his K2 successor mission. All planets were promoted to “candidate status”, but by the time ExoMiner came out, NASA had no resources to confirm whether or not they were actually planets.

This is interesting for several reasons. In the case of this latest discovery, securing 301 new planets in one fell swoop is a great achievement. This may be a small dent in the unveiling of the billions of planets believed to exist in our galaxy, but it’s a bigger step forward than NASA has ever taken before.

It’s also what makes the future of ExoMiner so exciting. With these 301 confirmed planets, NASA ExoMiner can train to work on other discovery missions. After planets are found using Kepler data, the next plan is to get ExoMiner to work with TESS (Der Transiting Exoplanet Survey Satellite) and confirmed the potential exoplanets found.

With each new planet giving scientists a better understanding of the galaxy we live in, the possibilities for ExoMiner are pretty surprising.
