Created by British astronomer Sir Patrick Caldwell-Moore, the list builds on the objects of the classicMessier catalog.
According toNASA, the images were taken at different points over the last 30 years.
Used for research, the images were not processed for public release until recently.

The up-to-date database now contains details and images of 87 of the 109 objects.
Some shots are partial, due to the telescope’s detailed field of view.
The Hubble Space Telescopewhich has received five upgrades over the past three decadeswill continue to pursue its celestial mission.

Fans of the final frontier can expect more images of the wonders of space for years to come.
The list of 109 sights includes those viewable from both the Northern and Southern hemispheres.
