Consider it a cosmic coincidence: On Nov. 18-19, two comets (ISON and Encke) are going to fly by the planet Mercury in quick succession. NASA's MESSENGER spacecraft will have a front-row seat for the rare double flyby.
I CANT WAIT EITHER
I like very much this video, I like to see the sky and the star!
En la madrugada del 18 tipo 5 de la mañana se vera?
Awesome video.
Gotta try and get up by 5 a.m. to see this!
this is beautiful
Nov 23 my brother just told me he spotted a comet left of Jupiter and it can't be ISON as our location we should not see it until an hour before sunrise. Could it be another one or the one they are speaking of here? 12:05am now
Considering gravity and the magnetism of the Sun, it's interesting that Encke's orbit doesn't go around the Sun or that it doesn't break up?
Ooh! Cosmic snowball fight!!
Amazing!
Comet Inky? Where are Pinky, Blinky and Clyde?
When did ISON's coma develop exactly?
AWESOME!
The conjunction will be BIBLICAL. iSON, Encke and Mercury are all SIBLINGS returning home for a family reunion. HEED Mercury's (NABU/NEBO) warning message! EYEs on the SUN!
And then later KNOBBO and New Brunswick will play a poker match, and the winner gets to rule over Malaysia for a week. Word is that "beer pong" will be involved.
wait what ison wont last long? hale bopp was visible for 18 months no fair :l
i want to be swimming looking at the comet like my dad did
Is there any evidence or known history of a comet striking a planet in our solar system?
shoemaker levy 9 broke up and hit Jupiter in 94
Billions have pounded every Planet in our Solar System over 4.5 Billion years or so. Today's comets are just some of the left over material that never made it into making the Planets we know now.
Very neat.
Why does NASA produce videos that sound like a newspaper article by a 3rd year Journalism student? This is disturbing. As a scientist, this is an insult to my intelligence. As a member of the public, they manage to bore the hell out of me with fascinating material.
It looks like Encke narrowly misses HITTING Mercury. That looks awfully close.
The video says 0.025 AU. An AU (astronomical unit) is the sun-earth distance, 93 million miles (149 million km). So the flyby is 2.3 million miles (3.7 million km) or about 9 times the earth moon distance. By cosmic standards, that's a near-miss.
Science!
Dry and hot.
Look minuto 3:24
apparently NASA isnt appart of the government shut down? whos getting paid to make this video?
Apparently you aren't aware that the shutdown ended on the 16th of last month, nearly a full month ago.
so the space fence is back on?
I wonder how many people will post here claiming to be disappointed because of (anything) and everything would be all better if only (anything) were done different.
Hey, if you don't like what you find here, don't come here.
First!
Dirty snowball theory again...
