NASA researchers were able to 301 new exoplanets Find. This increases the list of validated planets 4.569 at. They got help from a new one Deep Learning Netzwerk called ExoMiner. It is operated by NASA’s Pleiades supercomputer.

ExoMiner can distinguish actual exoplanets from various types of similar objects and “false positives”. To do this, it uses the test results and methods of previously found and recognized exoplanets and incorrectly classified planets. In particular, the large amounts of data that the Kepler Space Telescope and its successor mission K2 collected can be crawled with ExoMiner.

5 ways to find an exoplanet

For each individual planet, the scientists can understand why ExoMiner classified it as an exoplanet. The fact that the planets are validated does not mean that they will be confirmed. The validation process consists of evaluating data and statistics. Further observations must be made for confirmation. Therefore there is 5 ways.

The first is that Radial velocity to eat. If a planet is in the orbit of a star, it ensures that it sways back and forth. A change in color of the star is then observed on earth. This method has already been used 897 Exoplanets found. With the help of Astrometry, i.e. measuring and calculating Gerstirnpositions, this movement can also be detected. To do this, several pictures of the star and other surrounding stars are made. If it shows that the star is moving, the researchers look for exoplanets there. So far only one planet has been found like this.

If you look at the right time, you can observe the planet as it moves in front of its star. The star becomes darker as seen from the earth. So could 3,442 planets being found. Exoplanets can also be photographed directly by blocking out the bright radiation from their central star. 54 planets were discovered in this way.

The 4th method is that Microlens effect. Light is influenced by the gravity of an exoplanet and its star, much like a magnifying glass focuses sunlight. This Gravitationslinseneffekt can be measured on earth. So could already 118 planets being found.

More precisely than experts

The planets validated by ExoMiner were stored in the Kepler Archive, but could not yet be rated by anyone. According to ExoMiner project manager Hamed Valizadegan, the program is very reliable: “If ExoMiner says something is a planet, then you can be sure that it is true,” he says in a statement from the Jet Propulsion Laboratory. It is more accurate than other programs and human experts because people are always biased.
