Supernovae, either core collapse that that which caused the Crab Nebula (shown) or due to mergers of compact objects such as white dwarfs or neutron stars, are the source of all elements heavier than iron in the universe.

The famous Hubble Space Telescope image "The Pillars of Creation" (left image) are a small part of the HII region known as M16 or the Eagle Nebula (right image, mine). M16 is a region of active star formation and it is likely that stars are being formed in the pillars.

Many spiral galaxies have visible bars through their cores, such as M109 (shown). It is thought that some form of density wave radiating from the core is the cause of these features and that they are temporary.

Harlow Shapley used globular clusters (such as M2, shown) to determine the direction and distance to the centre of our Galaxy. Since the clusters orbit our Galaxy they orbit the centre of mass and by working out their position the centre of the Galaxy can be determined.

M57, the Ring Nebula, is one of 4 planetary nebulae on Messier's list of non-comet fuzzy objects. The ring shape comes from the fact that the nebula is roughly barrel shaped and we are looking down the end. evl.link/df

Change your wavelength, change your view. This image of M42 was taken through filters that only show emission lines of oxygen, hydrogen, and sulphur. These were then mapped to the standard R, G, and B of imaging with O being mapped to B, H to G, and S to R.

Stephan's Quintet is a group of 5 galaxies located in the constellation Pegasus. Of the 5 galaxies only 4 are part of a galaxy cluster with the fifth galaxy being a foreground object considerably closer to us.

Planetary nebulae (M27 shown) are the last stage of stellar evolution before low and intermediate (<8 solar mass) stars become white dwarfs. They are short lived objects, lasting between 50000 and 100000 years.
