Kjell E’s Cool Images – nr 54

Endless galaxies,  billions upon billions upon billions, of stars….

The European VISTA telescope (in Chile),  has photographed what was thought to be an unremarkable tiny little patch of sky, as big as the head of a pin, a region of sky known as the COSMOS field, in the constellation of Sextans.

The COSMOS field image reveals a handful of bright stars, set against a backdrop of fainter objects that are actually remote galaxies that themselves each contain billions of stars. In fact, more than 200,000 galaxies are recorded in this single view, ESO officials said.

The image is a combination of 6000 separate images, with an exposure time of 55 hours.  The finished product is the deepest infrared view of the sky of its size ever taken, according to ESO officials.
