![]() “This carefully-measured catalog is the foundation for directly answering one of astronomy’s most compelling questions - how many planets like our Earth are in the galaxy?” said Susan Thompson, a Kepler research scientist for the SETI Institute and lead author of the catalog, at the announcement. ![]() Over nine and a half years, the spacecraft trailed the Earth, scanning the skies for periodic dips in starlight that could signal the presence of a planet crossing in front of its star. Kepler identified 10 more of these planets, bring the total to some 50 of these Earth-like rocks, 30 of which have been double-checked and verified. Over half were discovered by NASA’s Kepler Space Telescope, a resilient observatory that far outlasted its original planned mission. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study. Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. Perhaps most intriguing, however, is the number of habitable Earth-sized planets that occupy just a small swath of space. Observatories Across the Electromagnetic Spectrum. For the first four years of Kepler’s mission, the space telescope trained its telescopic eye on a small region in space, specifically in the Cygnus constellation, and of the suspected exoplanets, 2,335 have been verified as actually being planets. At the same time, the space agency and a team of astronomers announced the discovery of a six-planet alien solar system, a find also made using the Kepler observatory. The telescopes construction and initial operation were. NASA announced the new interstellar additions at a Monday news conference at NASA’s Ames Research Center, completing the world’s most comprehensive catalog of exoplanets. The Kepler space telescope was part of NASAs Discovery Program of relatively low-cost science missions. Created by a devoted mission scientist, the image takes stock of the Kepler. Humanity’s premier planet sleuth, the Kepler Space Telescope, has spotted more than 200 more planetary candidates, bringing the list to over 4,034 suspected exoplanets. A photo may be worth 1,000 words, but a new depiction of NASAs Kepler mission is worth 1,235 potential alien planets. The Kepler Mission is a space observatory launched in 2009 by NASA to monitor 170,000 stars over a period of four years to determine the frequency of Earth.
