Washington, March 12: On 23rd February NASA surprised the whole world by announcing that the astronomers have discovered another solar system which is 40 light years away consisting of seven Earth-sized planets orbiting a star called TRAPPIST-1. NASA has released the video of the TRAPPIST-1.
This is basically an 11-by-11 pixel animation video that shows the dwarf star which exists in the TRAPPIST-1 system. This is recorded by the Kepler Space Telescope which is target pixel file. Kepler detects a change in brightness when a planet passes in front of a star from the vantage point of the telescope. It was caught while studying TRAPPIST-1 system.
NASA explains that this data gives scientists an "early look" so that they can shape their research proposals for further investigations that start next winter. They'll have a better sense of what they want to look for. Fully calibrated data will be available in May, NASA says, so don't despair if you're hoping for more polished material.
"The animation shows the amount of light detected by each pixel in a small section of the camera onboard NASA's Kepler space telescope. The light collected from TRAPPIST-1, an ultra-cool dwarf star approximately 40 light-years from Earth, is at the centre of the image. Not directly visible in the movie are the seven Earth-size planets that orbit TRAPPIST-1," said NASA.
