![]() Ongoing searches from ground-based telescopes keep adding to the count as well. Kepler looked for planets in a wide range of sizes and orbits. By Pat Brennan, NASAs Exoplanet Exploration Program. Just last month, NASA’s Kepler telescope discovered 95 new exoplanets beyond our solar system (on top of the thousands of exoplanets Kepler has discovered so far). NASA’s newest exoplanet hunter, the TESS mission, has confirmed more than 200 planets, with thousands more yet to verify, Kesseli says ( SN: 12/2/21). In 2009, NASA launched a spacecraft called Kepler to look for exoplanets. “Not only are we going to find tons and tons more exoplanets, but we’re also going to start to be able to actually characterize the planets,” she says.Īnd the search is far from over. But several projects, like the James Webb Space Telescope, are working on that, Kesseli says ( SN: 1/24/22). New data from NASAs James Webb Space Telescope (JWST) shows that the atmosphere of a rocky exoplanet in the TRAPPIST-1 system is either non-existent or incredibly thin, making it unfavorable. Otwell, Data: NASA Exoplanet ArchiveĪstronomers can’t say much about those worlds beyond diameters, masses and densities.

New era of exoplanet discovery begins with images of 'Jupiter's younger sibling' by W.

Otwell, Data: NASA Exoplanet Archive Graph: E. Hubble works alongside other telescopes to satisfy our curiosity about worlds beyond our solar system. Breakdown of confirmed exoplanets by type Graph: E. Small rocky worlds, some of which may resemble our own, come in fourth. 1 day ago &0183 &32 This discovery marks the conclusion of Kepler’s prolific planet-finding mission that contributed to the discovery of over 2,500 exoplanets. Super-Earths, not seen in our solar system, are a close second with Jupiter-like giant gassy planets coming in third. The 5,005 confirmed exoplanets can be categorized and divided into several distinct types, of which planets the size of Neptune are the most common. ![]()
