PHOTOS: NASA recorded the brightest comet in 2018 during its closest flight to Earth

NASA published photos of the brightest comet in 2018 on Thursday 46P / Virtanen, captured on December 16 and 17, while crossing the sky at a distance of 11 million kilometers from Earth, some 30 times from the Moon.

The Hubble Space Telescope caught comet brightness (nucleus), a part that is not normally visible from Earth. The coma is a current similar to the gas cloud that this celestial body ejects when it passes through the solar system.

Hablovo photographs will allow us to explore how gases are released from the nucleus, which consists of a comet ice and how the gas in the coma is chemically changed by sun and solar radiation.

Another instrument, the SOFIA telescope (modified Boeing 747SP), also took the comet when it was flying at an altitude of 12,000 kilometers.

SOFIA (Stratospheric Observatory for infrared astronomy) transmits a telescope that reflects 2.5 meters. The mission of SOFIA is to study the chemical prints of various types of hydrogen in the water comet, as some astronomers believe that water on Earth could be formed in comets and asteroids. Studying this celestial body will help to explore origin and history of water in the solar system, including the oceans of the Earth.

Although at a time when the comet is moving away, NASA highlights it there is still the possibility of seeing it From the Earth At present, the comet is located near the constellation Bika. However, according to the agency, it is barely visible to the naked eye even when the sky is very dark, so it is better to use binoculars or a telescope.

Comet 46P / Virtanen circles the Sun once every 5.4 years. Most of their steps through the inner solar system are farther away from the Earth, which, according to NASA, makes this year's exhibition particularly valuable.
