ISON

• baffles the scientific community

Washington. (Reuters) -. Comet ISON , which was considered disintegrated after his trip around the sun, seems to have survived, although only subtract your small nucleus, scientists reported today the U.S. Space Agency ( NASA ).

“Continuing a history of surprising behavior, substance belonging to Comet ISON has appeared on the other side of the Sun, despite not having been observed during their approach,” said NASA Solar Observatory on your blog.

Scientists had debated

two days after the passage near the Sun ISON on 28 November on whether the luminous powder was perceived in telescopes was just remnants of his encounter with the Sun or the comet nucleus was in its path away from the solar system.

“It appears that a part of the core ISON achieved through the solar corona and re-emerge,” said Karl Battams, one of the scientists who has followed the path of the comet.

ISON, first seen in September 2012 by Russian astronomers, is a special comet that comes from the Oort cloud, a bubble that surrounds the Solar System and, it is believed, is formed by the remains of the nebula that gave rise to the Sun and planets 4,600 million years ago.

comet, which has been traveling for at least a million years ago, its speed increases as it approaches the Sun, and it is estimated that the peak of speed is 1.3 million kilometers (828,000 miles) per hour, just when you turn around the sun

Nothing more to be discovered, ISON noted for its huge brightness, considering the great distance that separated him from the sun, and since then astronomers divided the world expected the comet passes its first test: perihelion, the time that would be closer to the Sun Its future now is uncertain.

“Now that has emerged and begun to shine we need to observe a few days to evaluate their behavior,” said Battams. Scientific ISON considered as “one of the most extraordinary comets we have ever encountered, and therefore corroborates the beautiful, dynamic and amazing that is our universe.”
