#KEPLER TELESCOPE FULL#
"Now that we know planets are everywhere, Kepler has set us on a new course that's full of promise for future generations to explore our galaxy. "When we started conceiving this mission 35 years ago we didn't know of a single planet outside our solar system," said the Kepler mission's founding principal investigator, William Borucki, now retired from NASA's Ames Research Center in California's Silicon Valley, when the telescope was retired in 2018. But they managed to do so, and the spacecraft continued in a second phase mission called K2. There were problems along the way, such as when the telescope experienced mechanical failures four years into the mission and engineers had to come up with a workaround. That was an ambitious goal, but the mission more than succeeded, as the telescope discovered an astonishing 2,600 exoplanets over its 11-year mission (via NASA). The idea was to have a telescope in orbit that could look specifically for exoplanets and try to learn about these distant worlds. You can see those videos here.Kepler was launched in 2009 when exoplanet research was still a budding topic, unlike the major focus it is today. It also took video of the TRAPPIST-1 system, six-planet star K2-138, and GJ 9827, showing the fluctuations in their brightness. It found our galaxy teeming with planets more planets even than the stars and stunned the world with many other first-of-a-kind discoveries. That field-of-view wasn't the last thing Kepler saw, though. NASA’s Kepler space telescope spent nine years in space, collecting an unprecedented dataset for science that has revolutionized our understanding of our place in the cosmos. This overlap means scientists here on Earth can compare the two images to try to better understand the data. TESS started officially taking science observations in August 2018, so there was a very brief period of time in which the two telescopes were working simultaneously.
The edge of the image also overlapped with observations taken by TESS, Kepler's successor. Another target was the GJ 9827 system, a nearby bright star that hosts a planet that is considered an excellent opportunity for follow up observations with other telescopes to study an atmosphere of a faraway world."įirst light (left) and last light, side by side. "It caught a glimpse of the renowned TRAPPIST-1 system with its seven rocky planets, at least three of them believed to be temperate worlds. "For this final field of view, Kepler's last observation campaign in its extended mission, the telescope was pointed in the direction of the constellation Aquarius," wrote NASA's Alison Hawkes. This means that the last full field of view Kepler saw before it closed its 'eyes' for the last time was still a rich one. You can't just nip into space to repair a telescope, so this had been anticipated with a modular array in which the failure of one sensor wouldn't knock out the whole lot of them. You can see a picture of it below - the layout of the CCDs is the reason Kepler's images are arrayed the way they are.Īs you can see in the last light image, there are a few blank squares where the CCDs had failed over the years. Kepler's camera was made up of 42 charged coupled device ( CCD) image sensors, each with a resolution of 1,024 by 2,200 pixels. The space telescope's final image - its 'last light' - was taken on 25 September 2018. Kepler's first light image was snapped on 8 April 2009. When a telescope takes its very first astronomical image, it's called ' first light'. ApKepler telescope delivers new planetary discovery from the grave by Jodrell Bank Centre for Astrophysics Color images from CFHT showing the field around K2-201 outside. And it was taking observations right up until the end.
The telescope ultimately lasted 9 years, 7 months and 23 days, revolutionising our understanding of exoplanets. Its mission had originally been planned for a duration 3.5 years.
