Na kineskom nebu se nedavno pojavio fenomen ’tri sunca’, gde su refleksija i prelamanje svetlosti stvarali utisak da našu planetu osvetljavaju tri ovakve zvezde.

I dok se tu radi isključivo o igri svetlosti, po mišljenju fizičara Breda Kartera, Zemlja bi stvarno mogla da dobije i drugo sunce, makar privremeno. Australijski profesor objašnjava da jedna od najsjajnijih zvezda na našem noćnom nebu ubrzano gubi masu i mogla bi uskoro postati supernova.

U pitanju je zvezda Betelgeus, koja se urušava i mogla bi bilo kada da ostane bez goriva i postane supernova. Kad god da se to desi, mi ćemo videti drugo sunce bar na nekoliko nedelja, a čak će i noć biti sjajna.

Karter smatra da bi to moglo da se dogodi 2012. godine, ali neki autori i astronomi kažu da ovakva zvezda može da eksplodira i za milion godina, i tada svejedno neće ugroziti Zemlju jer se nalazi 640 svetlosnih godina daleko.

This is a huge star, and when it goes, it will be at least as bright as that 1054 supernova…except that this one is 520 light years away, not 6,300 [...]

When it collapses, it will be at least as bright as the full moon, and maybe as bright as the sun. For six weeks. So the really lucky folks (for whom Betelgeuse is only visible at night) will get 24 hour days, everybody else will get at least some time with two suns in the sky. The extra hour of light from daylight savings time won’t burn the crops, but this might. Probably, all we’ll get is visible light (not gamma rays or X-rays), so it shouldn’t be an ELE. It’s sure gonna freak everyone out, though…..

Then it will form a black hole, but we’re too far away for that to matter.
