Astronomers have discovered a new comet, which they expected to manifest itself is incredibly bright in our sky during the second half of 2013. This comet, recently discovered by Russian astronomers, may be one of the brightest objects in the sky when it is closer to Earth in the next year.
At the moment, it is a tiny dot behind Jupiter. The comet was discovered on September 21 Vitali Nevski and Artyom Novichenko of the International Scientific Optical Network in Russia. Their discovery was confirmed on Tuesday by the International Astronomical Union.
According to the calculations of astronomers, the comet, with a near-parabolic orbit, heading straight to the Sun and the closest to come to him on November 28-29, 2013.
The heat from the sun’s glow vaporize the ice surface layer of the comet, releasing dust is inside, which greatly enhance the glow of the tail.
When the comet will approach very close to the Sun, then its glow may well eclipse the full moon.
The orbit of the comet, indicates its origin from the Oort cloud, a distant ring of icy objects that surrounds our solar system.
New comet called C/2012 S1 (ISON). Russian astronomers have found it in images taken with the 0.4 meter reflector.
While in the nearest point to the Sun in its orbit (perihelion), November 28, 2013, its brightness can reach -16, which is significantly greater than the brightness of the full moon. If this prediction is correct, the ISON will be one of the brightest comets in history, far exceeding this indicator comet Hale-Bopp in 1997, and very likely a comet and Pan-STARRS (C/2011 L4), which is the closest fit to Sun in March 2013.
Currently ISON can be seen in the north-west corner of the constellation Cancer. The brightness of 18 still does not allow to see it with the naked eye, but in the coming months it will become brighter and brighter, allowing yourself to see even amateur astronomers.
