Re: Hubble sees dark matter ring in a galaxy cluster
US astronomers on Tuesday presented the most solid proof yet of the existence of dark matter, a mysterious substance believed to make up more than a quarter of the universe.

Plaatjes doen het altijd beter. (hoe maak ik een foto van dark matter, antwoord beneden)
Astronomers using NASA's Hubble Space Telescope have discovered a ghostly ring of dark matter that formed long ago during a titanic collision between two massive galaxy clusters. The ring's discovery is among the strongest evidence yet that dark matter exists. Astronomers have long suspected the existence of the invisible substance as the source of additional gravity that holds together galaxy clusters. Such clusters would fly apart if they relied only on the gravity from their visible stars. Although astronomers don't know what dark matter is made of, they hypothesize that it is a type of elementary particle that pervades the universe.

WASHINGTON - Een duister aureool, gevormd door licht uit verre sterrenstelsels, vormt het belangrijkste bewijs dat in zeventig jaar is geleverd voor het bestaan van donkere materie in het heelal.

Re: Hubble sees dark matter ring in a galaxy cluster
Zonnevlekken lijken donker maar zijn het niet; ze zijn helderder dan een filmlamp. Ook deze "donkere materie ring" kan een gebied zijn dat wat minder licht uitstraalt dan zijn omgeving. Kwestie van contrast. Ik ben dan ook helemaal niet overtuigd, dat dit donkere materie is.DePurpereWolf schreef:Plaatjes doen het altijd beter. (hoe maak ik een foto van dark matter, antwoord beneden)

Re: Hubble sees dark matter ring in a galaxy cluster
eerst even hier kijken op welke manier zoiets wordt vastgesteld. Dat heeft namelijk niets met contrasten te maken, wat de reden is dat een zonnevlek "donker" is.
