A planned space telescope of nasa was able to find dozens of lonely exoplanets with the crowd of our earth, which no longer circle a star and instead drift alone through the milk strain. To this result come scientists of ohio state university in a recent study. The nancy grace roman space telescope (formerly wfirst) was allowed to significantly improve our knowledge of such lonely exoplanets, write. Maybe there is even more of these sky corpers in our milk strain as stars. In this case should "novel" hundreds of such exoplanets find, including several dozen with the mass of the earth or less.
In search of the lonely planet
The nancy grace roman space telescope is currently being developed, starting it in the mid-2020s. It is an infrared telescope, which was originally known under the name wide field infrared survey telescope. Only a few months ago it was renamed and now carries the name of the us astronomy and first nasa responsible for astronomy, nancy grace roman. Because of their crucial role in the development of the space telescope, it is commonly regarded as the "mother of hubble". The over-named space telescope should complete a series of scientific missions and search for particularly small exoplanets, among other things.

Like the astronomers around samson johnson from the ohio state university now in astronomical journal exports, novel should analyze a heavenly area in a similar manner as kepler has made. While kepler wanted to search for periodic blackouts of stars to identify the exoplanets responsible for dafur, roman should recognize when stars are briefly briefly. Lonely through the all-drifting planets or similar heavenly corporations, such a brightness increase could cause a brightness increase through the so-called microlens effect. In doing so, they turn the light beams of the star so that the for an observer does not appear twice, but enlarged.
According to the analysis, novel is about ten times as sensitive, such as previous missions. The telescope will look in the direction of the center of the milk strain. According to the models, novel was allowed to discover several hundreds of such exoplanets, down to such those who do not have more than a tenth of the ground of the earth. So far, less than two dozen such sky corpers are known. Several dozen of this lonely exoplanets with the mass of the earth should find novel, forecast the researchers. Depending on how many of these exoplanets identifies the nancy grace roman space telescope, our picture became dramatically better from the population of these single-course exoplanets. In addition, it will help to annoy your origin.
