VIEW IN SKY___ Older astronomy images tend to disappear as newer images of higher resolution are released. A shame, since these older images can be compared with newer ones. It would make a great website - numerous older astronomy pictures compared with newer ones. And they continue to improve, like the latest refurbished Hubble Space Telescope images are even higher resolution than previous images taken only years earlier by Hubble. Higher resolution means more detail in nebulosity filiments and globules, and even more background stars.
Overlay image of the Crab Nebula taken with telescope at Mt. Wilson and Palomar Observatories (undated). Although it was calculated and understood decades before Hubble Telescope, the neutron star at the Crab's center is not resolved, nor its energetic pulses, nor any detail of the filiments. Apply transparency to see the difference from the older image to the newer one.
