Rosetta Spacecraft Catches Comet Eruption
An anonymous reader writes: On March 12, the Rosetta spacecraft was imaging Comet 67P/Churyumov-Gerasimenko from a distance of 75 kilometers (46 miles) and by pure chance it spotted an eruption of dusty material from the shaded nucleus. Long-duration spacecraft are essential if we are to fully understand the evolution of a comet as it gradually heats up during its approach to the sun. And it just so happens that Rosetta is always in orbit around 67P's nucleus, ready to spot any transient event that could erupt at any time on the surface
This latest event focuses on the comet's shaded underside. It is assumed that some sunlight slowly heated an outcrop, providing enough energy to sublimate subsurface ices, ejecting vapor and dust as a jet. The transient jet was imaged and measured by Rosetta's scientific imaging system OSIRIS. There is also the possibility that a wave of heating passed through the icy material, eventually producing a more explosive jet event.

"And it just so happens", that is was designed to be in orbit around this comet. It wasn't just shot up at random, and "just happened" to fall into orbit around this comet.
Who writes this crap?
Basically, yes. This is what's referred to as "non-gravitational forces" (you can Google the term, but Wikipedia doesn't seem to have an article). It makes it harder to predict the orbits of comets under some circumstances.
If I spend 24x7 staring in your bathroom window you don't call it "pure chance" that I happened to see you taking a shower.
Well, if the Electric Universe guys had been correct about even a single prediction or observation since Velikovsky and company came up with it it might be easier to accept. For now it's just quackery, of the same level of science as homeopathy or phrenology.
