2024年10月28日 · In a press release on February 22, 2017, NASA announced the discovery of the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds–all of them with the potential for water on their surface – is an exciting discovery in the search for life on other worlds.

2018年2月20日 · Forty light-years away, seven Earth-size planets closely orbit a faint star called TRAPPIST-1. We now know more about this system than any other beyond our own.

2024年10月24日 · TRAPPIST-1 e is a terrestrial exoplanet that orbits a M-type star. Its mass is 0.692 Earths, it takes 6.1 days to complete one orbit of its star, and is 0.02925 AU from its star. Its discovery was announced in 2017.

2017年2月22日 · Spitzer, an infrared telescope that trails Earth as it orbits the sun, was well-suited for studying TRAPPIST-1 because the star glows brightest in infrared light, whose wavelengths are longer than the eye can see. In the fall of 2016, Spitzer observed TRAPPIST-1 nearly continuously for 500 hours.

2023年10月4日 · TRAPPIST-1 was the first system of transiting exoplanets to be discovered by the TRAPPIST project, back in 2016. At first, only three planets were identified, but...

2017年2月21日 · NASA's planet-hunting Kepler space telescope also is studying the TRAPPIST-1 system, making measurements of the star's minuscule changes in brightness due to transiting planets.

2021年1月22日 · The red dwarf star TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Located about 40 light-years away, these seven rocky siblings provide an example of the tremendous variety of …

2024年12月16日 · In stark contrast with a paper released last year that determined the exoplanet was likely to be bare and barren, new data obtained using JWST suggest that TRAPPIST-1b is either roiling with geological activity, or possibly shrouded in a thick atmosphere rich in …

2022年6月9日 · What is TRAPPIST-1? TRAPPIST-1 is an ultracool M-dwarf, the smallest class of star. Discovered in 2016 and 2017 by the Transiting Planets and Planetesimals Small Telescope , seven rocky planets — TRAPPIST-1b, c, d, e, f, g, and h — closely orbit their diminutive host star.

2024年2月28日 · Scientists have discovered that a potentially habitable planet is having its atmosphere stripped, a process that may eventually render the world, Trappist-1e, inhospitable to life. The stripping...
