NASA Predicts Comet ISON Is Still Dead ~ But The Evidence Is Far From Conclusive

Mmm...nope..no ET.

War against ET?

xDD no, no ET.

No and expect something stupid.

No. I have stayed up all night here waiting on the results. I'm sure they will be posted sometime in the next few hours.

LOL LOL

I am still checking every 5-10 minutes. I just hope they don't postpone it for another day...



Bong-hit to keep me awake!

Something waved to them....now they are trying to figure out what to do

Stop smoking the Devil's Spinach!

It makes this world bearable (well almost) and it promotes a healthy stool...And i wanna be Smashed for the Dooom!

Ison =wake up and grow a pair.

Ignoring ison = Restart the human race.

Well here we fucking go!

BREAKING NEWS: Comet ISON Is Still Dead


[link to hubblesite.org]

Astro right again!

"On December 18, 2013, the Hubble Space Telescope tried to observe Comet ISON one last time. As many people expected, there is no evidence of Comet ISON in these images."


There was some uncertainty in where Hubble should point to recover the comet because no observations showed the comet since soon after perihelion.

According to astronomer Hal Weaver, who devised Hubble's strategy, there were two likely locations of the comet, predictions based on previous positions measured when the comet was still visible.

Dr. Weaver also estimates that the faintest objects Hubble could see in these images would be about 25th magnitude. This means that Hubble could have seen comet fragments larger than about 500 feet (160 meters) in diameter.

We can't completely rule out the possibility that something is left of the comet. After all, it was seen after its passage close to the Sun, but disappeared not long after.

This material would still exist, but is likely very diffuse gas, dust, and very small pieces spread over an extremely large area.

Space Geeks right as always!!!

How can you be so sure that they were even pointing Hubble in the right location?

"there's nothing about this World that's worth taking seriously,
so, might as well just be stoned...."



Or get stoned Ison-style

They can't see anything smaller than a city killer?!?!?!?

WTH??????????????????????????????????????????????????????

xDDD what a bastards, and this is a expected new? hahaaha

This is far from conclusive for me....

all of the above

Thread: Comet ISON's debris is following the original orbit of the comet.
They pointed at two adjacent fields where the comet should be, there's nothing there. Empirical evidence shows that the debris cloud continued to follow the expected trajectory. Outgassing ceased at perihelion, which would minimize perturbations from outgassing. Whatever fragments are left are small - if a ~3km nucleus or larger were intact, even if it were not outgassing, it would be detectable by amateur surveys. Hubble's observations rule out anything larger than about 150 meters by my calculations, in close agreement with their own estimate of 160 meters.

Plugging in the numbers.
m_sun = -26.78
m = not detected, limiting magnitude about 25. I was going to guess the limiting magnitude would be about 26, but decided to wait for them to release the images. I wasn't too far off.
rh = .803 AU
delta = .4786 AU
A = Between .02 and .06 for a typical comet ( [link to www.physics.ucf.edu] ) but let's be conservative and say it's an unusually blacker than normal comet and take half the minimum value, so .01
Phi = .0281 (alpha of 97 degrees, beta of .02)
This yields a maximum radius of anything undetected in the images of 1.01019 x 10^-09 AU which works out to about 151 meters, very close to NASA's own estimate of 160 meters.

So there could be hundreds of fragments of Ison up to a size of 150m. but we have no clue where they are?

Are we supposed to be reassured by that?

I have this feeling we will see something red in the sky for Christmas, and it isn't going to be Santa Claus.

That is all.

You really think in 5 days this will happen?

Looks you wrong, nothing will appear in the sky, like asteroids, comets or shit like that, and yes, will be Xmas and the red-fat-drunk-bastard.

Your feeling is wrong.
