The red, green, and blue dots are star images resulting from combining exposures through different color filters: http://asterisk.apod.com/vie ... php?t=1218

:lol: Guys, jakub is asking about the RGB spots in the image, not about the cometary fragments! He is right that these spots are images of stars resulting from sucessive exposures through red, green, and blue filters. Following the APOD links, you can see the same effect in images on this European S...

Of course it’s an expansion of matter and energy. When you think about the BB, think about an observable super heated bubble of matter and energy exploding and expanding outwardly. Now ask yourself what is this bubble (i.e. observable universe) contained in -it's called the TOTAL universe. The bubb...

Hi and welcome, Bill! The yellow-green part of the solar spectrum is actually the brightest; radiation intensity peaks at about 500nm ( varying between 483 and 520 nm ), a wavelength which, on its own, would appear green-yellow. Reproduced below is an image of the sun's radiation profile and its bes...

Hi harry, the highest resolution inset in the link you provided above ( http://antwrp.gsfc.nasa.gov/apod/ap990216.html ) is 0.2 light-years, and the jet's thickness appears to be a small fraction of the inset's dimensions, so the jet is quite a bit less than 0.2 light-years in width. The jet stream ...

The lines are places of high magnetic field, the space between the lines are regions of low field strength. If this were true, a compass needle would bounce all over the place as you traversed the globe. Field lines are NOT physically real; they're conceptual aids. A magnetic field does not consist...

The universe is endless What about Olber's Paradox (the night sky is dark), which was brought up earlier in this thread? the parts within the universe move in a random chaos motion giving the largest parts such as super clusters of clusters of cluster galaxies territorial locations. They are random...

Both a nova and a supernova would be observed from Earth as a large and sudden brightening of a star followed by fading back to its original luminosity. Novae are caused by the fusion of matter (namely hydrogen) that accreted onto a white dwarf from a binary companion. Some novae, appropriately call...
