planets beyond our solar system

SOFIA confirms nearby planetary system is similar to our own, NASA announces astronomy and astrophysics fellows for 2017, Scientists make huge dataset of nearby stars available to public, Spitzer Space Telescope begins 'Beyond' phase, Venus-like exoplanet might have oxygen atmosphere, but not life, Astronomers help focus research in the search for another Earth, The next generation of telescopes are almost impossibly accurate, Snow line discovered in bright baby solar system, Astronomers find water clouds in cold Jupiter-like object, In space 'Jupiter' planets burn hot, not cold, First detection of methyl alcohol in a planet-forming disc, Unexpected excess of giant planets in star cluster, ‘Electric wind’ can strip potential Earths of oceans, atmospheres, Giant red stars may heat frozen worlds into habitable planets. The seven Earth-size planets of TRAPPIST-1 are all mostly made of rock, with some having the potential to hold more water than Earth, according to a new study published in the journal Astronomy and Astrophysics. The first exoplanets were discovered in the early 1990s, but the first exoplanet to burst upon the world stage was 51 Pegasi b, a “hot Jupiter” orbiting a Sun-like star 50 light-years away. The Exoplanet Exploration website won its first People's Voice Award in the Weird category. So what do we know about these exoplanets, and how can we find out more? The first exoplanet was discovered nine years later in 1992 and the numbers of known … The planets beyond our solar system are called “exoplanets,” and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. The flying SOFIA telescope has found a planetary system that has similar architecture to our own, in the system Epsilon Eridani. A newly discovered planet, in the "super Earth" size-range and some 12 light-years away, might be habitable. More variety is hidden within these broad categories. The ASTERIA satellite, currently in low-Earth orbit, is only slightly larger than a box of cereal, but it could help astrophysicists study planets orbiting other stars. The program's primary goals, as described in the 2014 NASA Science Plan, are to discover planets around other stars, to characterize their properties and to identify planets that could harbor life. An exoplanet or extrasolar planet is a planet outside the Solar System. University of Warwick researchers have identified a white dwarf pulsar – a star type which has eluded astronomers for half a century. Are there hidden planets in our solar system? •Is only 5 million miles from its sun, 1/8 the distance that Mercury is from our Sun. 15 Fascinating Planets Outside Our Solar System. That means we don’t have a “local” example of the most popular planet-type in our galaxy. Explore the planet types: Gas Giant, Neptune-like, Super-Earth and Terrestrial. Our nearest neighboring star, Proxima Centauri, was found to possess at least one planet – probably a rocky one. Researchers find some planets beyond solar system can view Earth 0 0 Tuesday, December 1, 2020 Edit this post More than 4,500 exoplanets have been discovered so far, with only a small portion thought to have the properties to contain life. With new NASA apps, you can take a selfie in space or tour a system of alien planets. Come along on this interstellar journey through time. NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star's habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface. TOI 1338 b is TESS’ first circumbinary planet, a world orbiting two stars. Data from NASA’s Kepler spacecraft showed that planets of a certain size-range are rare – those between 1.5 and 2 times the size (diameter) of Earth, which would place them among the super-Earths. Icy moons, galaxy clusters, and distant worlds! Nothing like them exists in our solar system. A super Earth that scorches in extreme heat because it circles so close to its star. A Super-Earth in the Neighborhood (Six Light-Years Away), Explore TESS, NASA's Latest Planet Hunter, Let NASA Bring the Universe into Your Home, Share Space Selfies and Tour Exoplanet Surfaces, New clues to compositions of TRAPPIST-1 planets, Astrophysics CubeSat demonstrates big potential in a small package, NASA’s planet-hunting TESS catches a comet before starting science, NASA finds a large amount of water in an exoplanet's atmosphere, Role models, footsteps, and the search for life, New planet is largest discovered that orbits two suns, Three giant worlds found orbiting twin suns, NASA web sites, social media honored in 2018 Webby Awards, NASA’s Transiting Exoplanet Survey Satellite arrives at Kennedy Space Center for launch, Proxima Centauri might be more sunlike than we thought, A fearless astronomer behind a game-changing telescope, Hubble probes atmospheres of exoplanets in TRAPPIST-1 habitable zone, Our living planet shapes the search for life beyond Earth, NASA team passes major technological milestone for characterizing exoplanets. It’s about 4 light-years away – more than 25 trillion miles (40 trillion kilometers). They can orbit their stars so tightly that a “year” lasts only a few days; they can orbit two suns at once. The new method for spotting small worlds is expected to reveal many thousands of distant objects in coming years — meaning these first hundred or so are likely just the tip of the iceberg. Astronomers have pinpointed which planets discovered by the NASA Kepler mission may sustain liquid water on their surfaces.
