What Did Kepler Teach Us? Celebrating the Space Telescope, 10 Years after LaunchMarch 6, 2019
NASA’s Kepler space telescope, launched March 6, 2009, was developed to search for planets around other stars and quantify their abundance in our galaxy. But over more than nine years of operations, through the initial four-year "prime" and subsequent K2 missions, Kepler contributed to many other areas of astronomicalresearch.
Kepler operated like a giant light bucket, collecting photons from stars, galaxies and other celestial objects. Its field of view was approximately 11 degrees across, roughly the size on the sky blocked out by an outstretched hand. By acquiring repeated images of a given field, astronomers use the space telescope’s data to precisely measure changes in brightness on timescales from minutes to months and longer. The results, called “light curves,” show different patterns according to the type of object being observed. (...)

A decade after being found, the first exoplanet candidate spotted by the Kepler space telescope has been confirmed as a real world.
The planet orbits a star initially dubbed KOI 4, for Kepler Object of Interest 4 (KOIs 1 through 3 were known before Kepler launched in March 2009). When the planet passed in front of the star, it blocked a bit of starlight from reaching Kepler in Earth’s orbit, alerting astronomers to the planet’s existence.
The Kepler team originally thought the star was about 1.1 times the width of the sun, which would make the planet about the size of Neptune. But then astronomers saw a second dip in starlight as the world passed behind the star, called a secondary eclipse. That second dip shouldn’t be visible for such a small planet, so the exoplanet candidate was dismissed as a false alarm. (...)

Il y a 15 ans, lancement du télescope spatiale Kepler par la NASA depuis Cape Canaveral par une Delta II-7925 10L.
Il découvrira de nombreuses exoplanètes jusqu'à sa fin de service en octobre 2018.

https://twitter.com/aisoffice/status/1765643651558867356The Kepler space telescope was launched into a heliocentric orbit OTD in 2009 to survey a portion of Earth's region of the Milky Way & discover Earth-size exoplanets. When deactivated in Nov 2018, Kepler had identified 5,011 exoplanet candidates to be investigated further.

16 years ago, NASA launched its first planet hunting mission: the Kepler space telescope. When it was conceived of, there wasn't a single confirmed exoplanet. Over Kepler's 9 years of service, it discovered over 2,600.
Today, our count is over 5,800. https://go.nasa.gov/3XtOLTY
