About this Image |
|
The bright star SAO28064 in Ursa Major is shining at glaring mag 5.63 intensity, yet it is hiding a very faint jewel:
A large but faint spiral galaxy (NGC 3733) is situated just 4 arc-minutes north from this dying red giant star.
It is mixing it's blueish light travelling 55 million years through space to the young photons sent from the star just 411 years ago.
