This artist's concept is one interpretation of what it could look like.This artist's concept allows us to imagine what it would be like to stand on the surface of the exoplanet TRAPPIST-1f, located in the TRAPPIST-1 system in the constellation Aquarius. Because this planet is thought to be tidally locked to its star, meaning the same face of the planet is always pointed at the star, there would be a region called the terminator that perpetually divides day and night. If the night side is icy, the day side might give way to liquid water in the area where sufficient starlight hits the surface. One of the unusual features of TRAPPIST-1 planets is how close they are to each other -- so close that other planets could be visible in the sky from the surface of each one. In this view, the planets in the sky correspond to TRAPPIST1e (top left crescent), d (middle crescent) and c (bright dot to the lower right of the crescents). TRAPPIST-1e would appear about the same size as the moon and TRAPPIST1-c is on the far side of the star. The star itself, an ultra-cool dwarf, would appear about three times larger than our own sun does in Earth's skies. The TRAPPIST-1 system has been revealed through observations from NASA's Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope. NASA's Jet Propulsion Laboratory, Pasadena, California, manages the Spitzer Space Telescope mission for NASA's Science Mission Directorate, Washington. Science operations are conducted at the Spitzer Science Center at Caltech in Pasadena. Spacecraft operations are based at Lockheed Martin Space Systems Company, Littleton, Colorado. Data are archived at the Infrared Science Archive housed at Caltech/IPAC. Caltech manages JPL for NASA.https://lespaceentrelesmots.com/wp-content/uploads/2017/02/500hoursdetection.jpgThis data plot shows infrared observations by NASA’s Spitzer Space Telescope of a system of seven planets orbiting TRAPPIST-1, an ultracool dwarf star. Over 21 days, Spitzer measured the drop in light as each planet passed in front of the star. SpitzerThis data plot shows infrared observations by NASA’s Spitzer Space Telescope of a system of seven planets orbiting TRAPPIST-1, an ultracool dwarf star. Over 21 days, Spitzer measured the drop in light as each planet passed in front of the star. Spitzer was able to identify a total of seven rocky worlds, including three in the habitable zone where liquid water might be found. This plot shows the change in light as each planet passes in front of its star. A diagram of the layouts of the orbits is shown on the right. The study established the planets' size, distance from their sun and, for some of them, their approximate mass and density. It also established that some, if not all, these planets are tidally locked, meaning one face of the planet permanently faces their sun. The system has been revealed through observations from NASA's Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope.https://lespaceentrelesmots.com/wp-content/uploads/2017/02/trappistsize.jpgTrappistSizehttps://lespaceentrelesmots.com/wp-content/uploads/2017/02/trappistdetection.jpgTrappistDetectionhttps://lespaceentrelesmots.com/wp-content/uploads/2017/02/solarsystemtrappistsystem.jpgSolarSystemTrappistSystemhttps://lespaceentrelesmots.com/wp-content/uploads/2017/02/spitzer.jpgSpitzerhttps://lespaceentrelesmots.com/wp-content/uploads/2017/11/trappistsystem.pngTrappistSystem2017-12-02T21:16:28+00:00monthlyhttps://lespaceentrelesmots.com/2017/03/26/communication-meteo-geolocalisation-la-discrete-omnipresence-des-satellites/https://lespaceentrelesmots.com/wp-content/uploads/2017/03/ariane5launch.jpgAriane5Launchhttps://lespaceentrelesmots.com/wp-content/uploads/2017/03/galileo.jpgGalileohttps://lespaceentrelesmots.com/wp-content/uploads/2017/03/enawo.jpgEnawohttps://lespaceentrelesmots.com/wp-content/uploads/2017/03/debris10cm.jpgDebris10cmhttps://lespaceentrelesmots.com/wp-content/uploads/2017/03/sputnik.jpgSputnikhttps://lespaceentrelesmots.com/wp-content/uploads/2017/11/soyouzlaunch.jpgSoyouzLaunch2017-12-02T21:16:20+00:00monthlyhttps://lespaceentrelesmots.com/2017/05/27/une-terre-spherique-mais-a-quel-point/https://lespaceentrelesmots.com/wp-content/uploads/2017/05/geoid.jpgGeoidhttps://lespaceentrelesmots.com/wp-content/uploads/2017/05/alps.jpgAlpshttps://lespaceentrelesmots.com/wp-content/uploads/2017/05/earthmay24.jpgEarthMay24https://lespaceentrelesmots.com/wp-content/uploads/2017/05/saturn.jpgSaturnhttps://lespaceentrelesmots.com/wp-content/uploads/2017/05/pan.jpgPanhttps://lespaceentrelesmots.com/wp-content/uploads/2017/05/disqueaccretion.jpgDisqueAccretionhttps://lespaceentrelesmots.com/wp-content/uploads/2017/11/sunrise.jpegSunrise2017-12-02T21:16:10+00:00monthlyhttps://lespaceentrelesmots.com/2017/09/15/destruction-de-cassini-une-collecte-de-donnees-hors-normes-jusquau-dernier-instants/https://lespaceentrelesmots.com/wp-content/uploads/2017/09/saturn.jpgSaturnhttps://lespaceentrelesmots.com/wp-content/uploads/2017/09/hexagon.jpgHexagonNASA's Cassini spacecraft captures three magnificent sights at once: Saturn's north polar vortex and hexagon along with its expansive rings.https://lespaceentrelesmots.com/wp-content/uploads/2017/09/verticalring.jpgVerticalRinghttps://lespaceentrelesmots.com/wp-content/uploads/2017/09/rings.jpgRingshttps://lespaceentrelesmots.com/wp-content/uploads/2017/09/enceladus.jpgEnceladushttps://lespaceentrelesmots.com/wp-content/uploads/2017/09/cassini.jpgCassinihttps://lespaceentrelesmots.com/wp-content/uploads/2017/09/titan.jpgTitanhttps://lespaceentrelesmots.com/wp-content/uploads/2017/09/huygens.jpgHuygenshttps://lespaceentrelesmots.com/wp-content/uploads/2017/09/earth.jpgEarthThis view from NASA's Cassini spacecraft shows planet Earth as a point of light between the icy rings of Saturn.
