‘Space’ has wonderful group of sky images
For the past 46 years, space telescopes have been sent into orbit allowing spectacular views of objects, using a variety of wavelengths (our atmosphere blocks off most of the waves shorter than light and a good deal of the waves longer than light).
Here are highlights for 2014 night skies
