Must they tell us about Eveyone ? We can See ISON Ourselves.....

Scientists say comet ISON is headed to the sun, and if it survives, the comet would be visible even in daylight from Earth.


CAPE CANAVERAL, Fla. — A recently discovered comet, dazzlingly bright even though it is still almost as far away as Jupiter, is racing toward a November rendezvous with the sun, officials said Tuesday.

If it survives the encounter — and that's a big if — the comet may be visible even in daylight in Earth's skies at the end of the year.

Discovered by amateur astronomers in September, comet ISON is about to reach the outer edge of the asteroid belt, located about 280 million miles from Earth, said William Cooke, lead scientist at NASA's Meteoroid Environment Office at the Marshall Space Flight Center in Huntsville, Ala.

The comet is shedding dust from its nucleus at a rate of more than 112,000 pounds per minute, the result of heating by the sun, observations from NASA's Swift telescope show.

That level of activity is unusual for a comet still so far away from the sun. It could spell its doom.

Preliminary measurements made with the Hubble Space Telescope, which captured an image of the comet that was released Tuesday, indicate comet ISON's body is no more than 4 miles in diameter.

The comet's nucleus will continue to shrink as it flies closer toward the sun and heats up. The rock-and-ice object could break up completely before it gets as close as 700,000 miles from the sun's surface Nov. 28.

A comet in the 1970s passed 10 times farther away than that and partly disintegrated, Cooke said.

"I doubt this thing is going to survive. I guess we won't know for sure until we look for it to come out from behind the sun," he said.

The comet was named for the International Scientific Optical Network, or ISON, telescope that made its discovery.

Solar Ballet






A massive sun eruption on New Year’s Eve could have swallowed 20 earths.

According to NASA, the massive eruption extended more than about 150,000 miles out from the sun. But despite its massive size the eruption wasn’t too powerful. The blast did not have enough power to escape the sun’s gravity and was pulled back down to the surface of the sun.


NASA officials wrote in a statement:

“A solar eruption gracefully rose up from the sun on Dec. 31, 2012, twisting and turning. Magnetic forces drove the flow of plasma, but without sufficient force to overcome the sun’s gravity much of the plasma fell back into the sun. The length of the eruption extends about 160,000 miles out from the Sun. With Earth about 7,900 miles in diameter, this relatively minor eruption is about 20 times the diameter of our planet.”

NASA also recorded a video of the sun eruption, which lasted more than four hours, which they called a Solar Ballet.

Space.com reports that the sun is currently in an active phase that will peak later this year.

Here’s a photo of the sun’s massive eruption on New Year’s day.
