Hello all Astro enthusiasts,
You may have all heard the sad news of NASA’s Kepler space-based telescope encountering a failure in one of its reaction wheels back in May, well, despite after months of attempted recovery of the telescope NASA has sadly had to ‘call it a day’ and give up any hope of this wonderful piece of inspiring astronomy sparking back into life.
What was Kepler?
Kepler is a spaced-based telescope named after the scientist ‘Johannes Kepler’, who is famous for transcribing the 3 laws of planetary motion, developed by NASA its aim was to analyse and survey the ‘Light Curves’ of over a 150,000 stars in a fixed field of view (FOV). What was the reason for performing such a survey? To detect the 1% dip in brightness of a star that could be potentially have been caused by a distant planet, orbiting around a distant star, what Astronomers would call an ‘Exoplanet Transit’; like the moon eclipsing the sun in a total solar eclipse, a distant planet can effectively eclipse part of a distant star’s light. Kepler could read and resolve/see these small ‘blips’, and as a result the data obtained from Kepler has confirmed the existence of over 503 planets that orbit around other stars, in other words planets are a very common occurrence during the birth of stars.
As a result, it’s sad that Kepler won’t be bringing back any more new data, but there is still a lot of data that needs crunching and analysed, so all is not completely lost and there are still exciting times ahead.
