End

More than 2000 comets have been observed, which came very close to the Sun in the past 15 years. Read more:

The prophecies indicate a threat to Earth through celestial bodies and to be able to imagine such a scenario it helps to keep an eye on the many reports about such collisions of celestial bodies. Here again such a report I read today:

 

Astronomy - Satellites observe end of a comet

A comet ended in the atmosphere of the Sun. For the first time astronomers could watch it.

For the first time astronomers were able to observe the end of a comet in the atmosphere of the Sun in detail.

… they could observe how the tail star raced into the Sun with about 2.3 million kilometer per second on the 6th of July 2011.

The comet got up to about 100,000 kilometre to the surface of the Sun, until it had dissolved completely, researchers reported about the last 20 minutes of the tail star.

By the astronomers being able to observe how the comet dissolved over a certain distance flown in a certain time, the original dimensions could be estimated.

“We could narrow down its size to 50 to 100 meter length.”

“And it probably weighed at least 70,000 tons, so much as an aircraft carrier.”

The comet with the catalogue number C/2011 N3 was discovered only on the 4th of July 2011 with the European-American Sun satellite “SOHO”. When two days later it then raced into the atmosphere of the Sun in the field of vision of “SDO”, the icy core was already broken into pieces of 10 to 50 meter.

These fragments covered themselves in an about 1000 kilometre big dust and gas cloud, the so-called coma. An about 16 000 kilometre long, pulsating comet tail followed it. “The light pulses in the tail belonged to the most interesting things we have seen.” “The tail of the comet became brighter up to four times every one, two minutes.”

Presumably the core of the comet has released alternately more or less material into the tail. From the pulses it can be estimated how fast molten material of the comet wanders through the tail. “And that again helps us to measure the weight of the comet.” The Sun observatory “SOHO” has observed more than 2000 comets, which came very close to the Sun in the past 15 years.
