Scientists more accurately measure the brightness of the universe

Based on this method, the sky would have the brightness of a 60W bulb seen from 2.5 miles away. It would be extraordinarily faint, but not completely pitch black.

Previous approaches relied on ultraviolet light from short-lived giant stars, but these were not as reliable since they could miss the faintest stars. The blazar approach is measuring light from every galaxy, even when they are otherwise too small to detect. Og mens folk har undersøkt måling av inter-galakse baggrundslampen før, prøvde de at kolliderer lyset direkte og måtte bekæmpe interferens fra Milky Way.

Dette er ikke en helt korrekt visning, at minst ikke ennå. I tillegg til det resterende 1

0 procent (vigtigt når det dækker hele det kendte univers), er det ikke lys, der ramte støv og var reemitted som infrarød. De forskere har faktureret i den støv, selv om det kan være et spørgsmål om at få gamle blazars til at fylle i flere data. As it stands, the information available now could provide a considerably clearer picture of star formation in the universe, including the frequency of new stars.
