Spiselige er de nok ikke, med mindre man er en gavflab som Kim larsen.
Indtil nu har det været et spørgsmål af galaktiske dimensioner. Hvordan ser galakser ud? Som en pandekage, et søpindsvin eller en fodbold? "The faster a galaxy spins around, the flatter it is. And so we know that the spin of the galaxies associated with things that have happened in its history for example" "..most galaxies are actually like a beach ball with different degrees of 'squashedness'." "But we have found there is a population of galaxies as well that doesn't have a necessarily two of its axes that are the same. So we found galaxies that are a bit more potato-shaped." "If our galaxy was more potato-like or more round, we would have stars all across the sky, not just that one strip" Shape of galaxies could shed light on mysteries of space - ABC News (Australian Broadcasting Corporation) |
