Comet NEOWISE at its closest distance to Earth

Comet C/2020 F3 (NEOWISE) is currently visible naked eye in the Northern hemisphere and passing at its closest distance to the Earth.

It is the brightest comet since Great Comet Hale–Bopp in 1997, and from dark sites it displays a long magnificient tail in the Ursa Major constellation. TRAPPIST-North telescope has been monitoring the comet over the last weeks with peculiar filters to measure the composition of its atmopshere. In this color composite image of the head of the comet taken on July 23, the blue color is light emitted by the gassous CN molecule, the green color by the C2 molecule and the red-yellowish color by the dust escaping the comet nucleus due to the heat of the sun and forming the comet tail.
Comet NEOWISE is a long period comet with a near-parabolic orbit discovered on March 27, 2020, by the NASA infrared space telescope WISE. Don't miss the comet, it will only come back in 6700 years !
