A Window to the Universe
The big, blue stars scattered across the picture are stars in our galaxy, fairly close by, which is why they appear so large and bright. If we zoom in further, we see hundreds of distant galaxies! Grand, spiral galaxies; irregular, shapeless galaxies; young blue galaxies; and older red galaxies. This picture has everything! And doesn't it blow your mind to realise that each of the tiny dots in this picture is a galaxy containing billions of stars, many of which are much bigger than our Sun?!
