Comet ISON developed double tail
Posted by Chillymanjaro on November 12, 2013 in category C/2012 S1 (ISON)
Comet ISON is every day more and more closer to the Sun, and with every new day it reveals more new details. More astronomers report clearly visible double tail feature. Primary ion gas tail developed a dust tail companion so now Comet ISON is double tail comet.
Primary tail is in fact ionized gas pushed away from the comet by solar wind and it always points almost directly away from the Sun. The other tail is the dust tail which traces the comet's orbit and does not point directly away from the sun as the ion tail does.

In the meantime, NASA's Chandra X-ray observatory, ninth spacecraft that is now observing Comet ISON, captured first X-ray image of comet on November 3, 2013, detected in the ACIS-S low resolution spectro-photometer. The morphology looks pretty normal, with maximum brightness closest to the nucleus, but a bit offset towards the Sun. Only in the past 20-years have we known that comets emit X-rays, so seeing ISON shining brightly at these wavelengths is very exciting. If the comet survives its close encounter with the Sun, another X-ray imagers on the NASA MESSENGER spacecraft could take more interesting shots.

ISON is now inside the orbit of Venus and it is currently moving through the constellation Virgo low in the eastern sky before dawn. It is moving extremely fast now at around 50 km/s (180 000km/h, 112 000mph), and approaching twilight skies so it will become increasingly difficult to observe. ISON is now shining as bright 8 magnitude star

At its closest approach it will be 64 million km (40 million miles) from Earth, just under half the distance between our planet and the Sun.

Maybe it will come to Earth it doesn't look like a comet at all. Does it look like a Mother Ship? Very well could be a guidance system. Maybe its part of the Galactic Federation of Light observing us.
And the question is, what are those parts, I think they are Mother ships along with 5 or 6 Cigar type ships along side.. I posted that blog several wks ago. Some are saying that these ships are from the center of our Universe and are here to help us and the Earth into the Ascension Event. The 24th to the 28th will be an interesting time !! Adonai
it was shown a couple weeks ago that the comet had multiple parts inside traveling in a cluster. If one or more strays from the group you will see this happen.
Very Pretty!
