The Kepler mission and its extension, called K2, discovered thousands of exoplanets. It detected them using the transit technique, measuring the dip in light intensity whenever an orbiting planet moved across the face of its host star as viewed from Earth.Transits can not only measure the orbital period, they often

NASA to Make Announcement About Kepler Telescope

NASA is about to make an announcement about the Kepler, potentially to say the planet-hunting telescope has finally run out of fuel almost a decade after being launched into space.A tweet from the agency that in the teleconference, it will “provide an update on the status” of the telescope, and

Last gasp? NASA fires up fading Kepler telescope for Campaign 19

Kepler's fuel stocks are dwindling, but there may be life left in it yet

Although the science mission of its successor, the Transiting Exoplanet Survey Satellite (TESS), is now underway, NASA isn't done with the Kepler Space Telescope just yet. Its scientists have awoken the deep space probe to gather scientific data yet again, though with an unknown amount of fuel and a compromised
