NASA's NEOWISE mission released data for 4 years of searching. The project was resumed in December 2013, after which a comet and asteroid hunter scanned the sky almost 8 times, observing and characterizing 29,375 objects. This also includes 788 near-Earth objects and 136 comets.
Near-Earth objects - asteroids and comets, pushed by the gravitational attraction of the planets in our system, because of which they find themselves at a dangerously close distance to us. Last year, NEOWISE found 10 objects that were classified as potentially dangerous asteroids. These are especially large or close to the Earth.
In general, NEOWISE now characterizes the size and reflectivity of more than 1,300 near-earth objects since launch, providing an invaluable resource for understanding the physical properties of these objects (their composition and point of arrival). The NEOWISE team released an animation demonstrating the observation of a telescope over 4 years of work.
Over the 4 years of operation, NEOWISE has managed to produce more than 2.5 million infrared images of the sky. These data are archived, where you can find 10.3 million images, as well as more than 76 billion potential sources of their arrival.
Initially, the mission was called WISE (Multiple Infrared Explorer). The spacecraft was launched in 2009. In 2011, he went into hibernation after the end of the mission on primary astrophysics. In September 2013, it was reactivated, renamed NEOWISE and given a new task - to help NASA find and characterize near-Earth objects.
