Megastar-Birth Cluster is Biggest, Brightest and Hottest Ever Seen

A mysterious arc of light found behind a distant cluster of galaxies has turned out to be the biggest, brightest, and hottest star forming region ever seen in space. The so-called Lynx arc is 1 million times brighter than the well known Orion Nebula, a nearby prototypical star birth region visible with small telescopes. The newly identified super cluster contains a million blue white stars that are twice as hot as similar stars in our Milky Way galaxy. It is a rarely seen example of the early days of the universe where furious firestorms of star birth blazed across the skies. The spectacular cluster's opulence is dimmed when seen from Earth only because it is 12 billion light years away.

Kawabill´s note:
Impressive to ´see´ the tremendous amount of energy that floats around in space. Just think about it being "only 12 BILLION" = "12,000 MILLION" light years away........
I think if these immense distances exist somewhere in our dimension, who are we with our simple mind - that perceives a lifetime and a trip around the earth as being long and big - thinking we can understand just a bit of what is around us....

To put it in a little more perspective;
A light-year is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers each second.

So in one year, it can travel about 10 trillion kilometers.
More precisely, one light-year is equal to 9,500,000,000,000 kilometers.
