If NASA don't have the money to contact the probe, I'm sure the Navy has the odd billion spare to find a use for it.  If it is passing a L point then it has to be worth trying to stabilise and then using....

there is something just plain-ass wierd about this one..and i can't figure out why

but if it blows some communication satilites..maybe we can start a telepathic forum.. ;)

Did you mean telepathic..................................................or did you mean tele-pathetic?  :))

You want WEIRD?  This is the latest from Hubble (artists impression though) Comet now has SIX TAILS

So okay... the real Hubble image is not as dramatic, but still ODD

This is really strange! They call P/2013 P5 an "asteroid" but it looks like a comet with tail(tails) and all.  Does anyone know if there has been another "asteroid"  with a similar signature?   :o

I found this:


Summary Table
Asteroid    A relatively small, inactive, rocky body orbiting the Sun.
Comet    A relatively small, at times active, object whose ices can vaporize in sunlight forming an atmosphere (coma) of dust and gas and, sometimes, a tail of dust and/or gas.
Meteoroid    A small particle from a comet or asteroid orbiting the Sun.
Meteor    The light phenomena which results when a meteoroid enters the Earth's atmosphere and vaporizes; a shooting star.
Meteorite    A meteoroid that survives its passage through the Earth's atmosphere and lands upon the Earth's surface.

It gets confusing to me, but then it is way past my bed-time.  ;)

Funny, when I run it it looks like it is turning to the photo right.

Observe Comet ISON at its best


Find out how to view what promises to be the brightest comet of 2013 and likely one of the two or three brightest comets of the 21st century — so far.

Dates and viewing times for best view... I think this is northern hemisphere...

Comet ISON should be a spectacle when it passes near Mercury and Saturn in morning twilight November 24.

According to Spaceweather.com this morning there are 4 comets showing at one time, then we have P/2013 P5, what ever it is?  Sorry for a sloppy post,my old computer and old me are limited.

Pictured from left to right are exploding Comet LINEAR X1, sungrazing Comet ISON, short-period Comet Encke, and the brightest of them all, Comet Lovejoy. All four are visible in binoculars or backyard telescopes, and Comet Lovejoy (mag. +6.0) is visible to the naked eye from dark-sky sites. Comet ISON is actually one of the faintest of the group; only expanding Comet LINEAR X1 (mag. +8) is more difficult to see.

An apparition of so many comets at once is a rare thing, and amateur astronomers are encouraged to wake up early for a tour of the pre-dawn sky. Dates of special interest include Nov. 15-18 when Comet LINEAR X1 passes by the bright star Arcturus, Nov 17-18 when Comet ISON has a close encounter with Spica, and Nov. 18-20 when Comet Encke buzzes Mercury. These stars and planets make excellent naked-eye guideposts for finding the comets. Meanwhile, bright Comet Lovejoy is approaching the Big Dipper; if you can't see it with your unaided eye, a quick scan with binoculars will reveal it. Sky maps: Nov. 10, 11, 12, 13, 14, 15, 16, 17, 18, 19.

Not blocked, but there's an imbedded Java applet that is VERY slow to load.
