NEWS ROOM: - Forty-six million light years. Try to think of how far can such a distance, in space and time (later to calculate how many miles is).

Down the Hubble Space Telescope has captured this beautiful picture of the spiral galaxy NGC 2841 , belonging to the constellation Ursa Major.

The instrument used is the edge of a new camera 3 WFC (Wide Field Camera 3) , for a total exposure time of 2 hours, between 5 and 7 January 2010.



four different filters were used with wavelengths ranging from ultraviolet to near-infrared through the visible band.

There is also a great video


Now let's try to calculate how many kilometers are 46 million light years

46 million years light

= 46,000,000 x 365 days = light
46,000,000 x 365 x 24 hours = light
46,000,000 x 365 x 24 x 60 minutes = light
46,000,000 x 365 x 24 x 60 x 60 / 2 = light
46,000,000 x 365 x 24 x 60 x 60 km x 300,000 =

435,196,800,000,000,000,000 kilometers, that is a bit 'more of 435 billion billion miles.

From gasp, no?
