Capturing of our Earth image from the spacecraft is a tradition for NASA. The recent view of Earth which was released by NASA is something different. The picture which was taken by Kepler space telescope, which had searched more than 2500 unknown worlds for us shows that our planet looks like a beam of cosmic light.
Captured on December 10, 2017, the spacecraft shows that the view of Earth is so bright that it blocks the view of neighboring Moon and bleeds the instrument’s sensors. The photo appears to be very bright as the Kepler’s light-sensing photometer is very sensitive. The device is designed in such a way that it can detect small brightness in the space.
The Kepler mission had nearly got to end in May 2013. There are four orientation-maintaining wheels present in Kepler to keep the telescope in precise pointing ability, but one of the wheels failed. This leads to the end of this mission, but soon mission representative found a way to keep the telescope stable. This was done with the help of sunlight pressure, and this marks the start of a new mission called K2. When the K2 mission started, Kepler keeps searching for new celestial objects.
With the release of this photo, it also marks the nine-year anniversary in space. Kepler has a data of more than 2,500 planets, stars supernova, and other astrophysical phenomena. As this mission is its second operating phase and very soon going to end, so a new planet hunter is going to join Kepler. NASA is going to launch Transiting Exoplanet Survey Satellite (TESS) on April 16. TESS is scheduled to study more than 2, 00,000 nearest stars present outside of our solar system.
