Kepler isn't the only planet hunter, though. Since 2018, TESS has added over 5,000 more transit detections, and just over 200 exoplanets have been confirmed from that data. Meanwhile, ground-based telescopes search for alien worlds in other ways, ...
The primary data we have so far on how many exoplanets might exist in our galaxy comes from the now-retired Kepler Space Telescope, which surveyed the sky between 2009 and 2018, measuring the brightness of some 150,000 stars to search for exoplanets using the transit method. This mission lai...

We cross referenced our results with a catalogue of known exoplanets that are classified to be in thehabitable zoneto identify those that are primed for life. We found two candidates. Kepler-452b is the smallest exoplanet we know that resides definitively located in both the habitable and abioge...
“The problems arising when interpreting the data from WASP-39b are well known from many other exoplanets – regardless whether they are observed with Kepler,TESS, James Webb, or the future PLATO spacecraft,” explains MPS scientist Dr. Nadiia Kostogryz, first author of the new study. “As...
While astronomers suspect there are a trillion or moreexoplanetsin theMilky Way, we have detected only a few thousand so far. With our rudimentary methods, however, we are biased toward seeing planets that orbit close to their parent stars. This means that we are exceptionally good at finding...
“exoplanets,” but that puts a telescope lens between you and them. i could stick to “planets,” which would connect them to the shapes in our solar system. but “world”: that’s a thing you are (or some other species is) meant to exist on, a thing of the same sort that we ...
That would certainly “spur more thinking about how to look at that up close,” Vanderplas said. Within our lifetimes, depending on funding, we could see the discovery of a truly “earthlike” (i.e. one bearing water)exoplanets. In the meantime, just the presence of these planets is encou...
When a planet passes in front of its host star, it causes a small transient dimming of the star. This so-called transit can be measurable, depending on the size of the planet and the sensitivity of the instrument. In fact, the majority of the exoplanets known to us today have been disc...
55 Cancri e is classified as a super-Earth, but it’s far from Earth-like. (Many exoplanets are interesting because of potential habitability but don’t even mention habitability in this case.) It orbits so closely to the star that its surface is molten and reaches a temperature ...
