I'd like to propose a conspiracy theory, of the out going Bush government launching a weapon of apocalyptic proportions into Jupiter, with the payload finally reaching its destination last night.
This wasn't meant to be seen people.
Ah, the Lucifer project.
I'd like to propse an alternative theory based on the simgle posted image, that it's simply another celestial body (say one of Jupiter's moons) passing by in front. I need video.
A tip? Anthony bloody imaged the whole thing and woke them up!
ET made it home
his picture is better also.
Shame the comet didnt come and hit earth and wipe us all out. Then I wouldn't have to go to work every morning.
P.s. i work in support.
How come NASA dont fly the shuttle to Jupiter to take a look? After all, with technology these days it should be easy.
they didnt even see it coming ... but if something like that were to hit earth, we'd be wiped out ... lucky jupiter takes alot of hits for us
Why is that you rekon? High gravity pull of Jupiter? Luck on our behalf i mean space is pretty big!? Or we're all in the Matrix and events like this are fabricated...
What if I said all of the above?
I was interested to hear how big the experts thought the object was that hit Jupiter. Some said earth sized! After looking around for credible scientific estimates (I know it is a bit early) I found this report:
"Professionals on the Keck 10-meter telescope and NASA’s Infrared Telescope Facility (IRTF) were able to observe the spot. According to Keck observations published on Central Bureau Electronic Telegram 1882, the spot covers 200 million square kilometers which is nearly half of the Earth’s surface area".
So I have a problem. Yes, it is nearly half, if you took the literal surface area of the planet. However when you push a sphere through an object, the hole is only as wide as the sphere's diameter. The total area of the hole is the (earth diameter/2)^2 x Pi. Using 12,700km as the diameter, the area of the hole the earth would leave is 127 million sq km. This is very different to the surface area of the sphere (ie land and sea area of earth), which is 4 x Pi x (diameter/2)^2. The surface area of the earth is 510 m sq km, which appears to be what the reporter misquoted (200m sq km hole size being less than half the 510m sq km total surface area of earth).
As objects this size are invariably round (gravity), it means that the hole was caused by something at least as big as the earth!
So it got me thinking, are we so blind that we cannot see an object at least as big as earth, well within our solar system? We seem to be able to spot planets outside our solar system by gravitational wobble, shadows etc, why cannot we see something this big just next door?
Are my calculations correct?
NO! Ever seen an impact crater on any kind of solid planet? Ever heard of the Tunguska event?
The impacting body does not equal the size of the crater or imprint or damage spread.
Looking at previous Shoemaker-Levy comet impacts on Jupiter, it seems that a 3km object could leave an earth sized hole. Looks like some of the explanations in the popular press are just going to be confusing. It will be interesting to see how big the hole gets, if it is still expanding.
i dont think it would earth sized LOL .. you would see 1 massive explosion ..
Thank God it didnt come our way!!
Yeah. Though we're a much smaller target.
