Revealed in the summer, a comet, rapidlyapproaching Earth, was photographed with high resolution. The Russian astronomer Gennady Borisov discovered the celestial body flying into our solar system from the side of the constellation Cassiopeia. The resulting image of a comet allowed scientists to see the true "face" of the comet and to compare it with our planet.
To get a starry photoTraveler used the equipment at the Keck Observatory in Hawaii. The low-resolution spectrometer received a high-definition image of a comet, which will fly just 300 million km from Earth in December 2019. The comet will cross the solar system and go on a further journey.
As we approach our system, the cometgradually increases the temperature. The comet's core is only 1.6 km in diameter, but the comet's tail stretched over more than 160 thousand km, which is many times greater than the diameter of the Earth (12 742 km). The tail of the comet, as it became clear from the photograph, is formed from dust and gas.
Formed outside the solar system inas a result of a collision of celestial bodies, the Borisov comet provided Earth scientists with a wealth of material to study the physical phenomena associated with the formation of celestial objects after catastrophic planet collisions.
Throughout history, this is just the second object discovered by scientists that flew into our solar system from interstellar space. The first was the asteroid Oumuamua (scout), discovered in 2017.
