A well documented supernova occured, which created the Crab Nebula.
-
Nicholas Claude Fabri Peiresc discovers the Orion Nebula
-
Philippe Loys de Cheseaux discovered the eagle negbula, swan nebula, omega nebula, and lobster nebula
-
Charles Messier found a hazy patch in the sky while he was searching for a comet. He realized it didnt move across the sky, so it was very different than a comet. To prevent other astronomers from making the same mistake, he decided to make a catalog of discoveries in space. This newly discovered feature was named Messier 1, commonly known as M1.

Charles Messier discovered the dumbbell nebula
-
Pierre Mechain discovers the Owl nebula
-
Catalogue of One Thousand New Nebulae and Clusters of Stars was pulished by William and Caroline Herschel
-
Andrew Common constructed a refracting telescope in his London backyard. This was the first tie stars and detail were shown in the pictures that were too faint to be seen with the human eye.
-
William Parsons used the biggest telescope in the world to look at M51, which was a cloudy nebula in the sky. He saw the spiral shape and therefore discoved spiral nebulae.
-
Henry Draper used the dry plate photography process using a refracting telescope to get 51 minutes of exposure of the Orion Nebula. This was the first astrophotography of a nebula in history.
-
Laplace proposed the nebular hypothesis in the early 18th century. This stated that a cloud of dust collapses and begins to spin faster because of angular momentum conservation, forming a nebula.
-
Edwin Hubble showed that the spiral nebulae which we thought were within the milky way were actually other galaxies far away.
-
Astronomers found an odd double helix nebula near the center of our milky way.
-
Astrophysicists used sophisticated computer modeling programs to find out that the Orion Nebula is held together by the gravitational pull of a very large black hole.
-
A population of planetary nebulae are discovered to oddly be pointing in the same direction.
