Hubble is famous for its detailed images of distant wonders, but with the benefit of a dark, clear sky, anyone with a telescope, binoculars, or sometimes even the unaided eye can see some of the same objects Hubble has observed. These catalogs of backyard-friendly cosmic targets give information about each object and help you locate it in the night sky. Break out your telescope or binoculars and compare your observations with those of Hubble.
The Ring Nebula, also known as Messier 57, is tilted toward Earth so that we see the ring face-on.
The Whirlpool Galaxy, also called Messier 51, is 31 million light-years from Earth.
Messier 16, the Eagle Nebula, provided Hubble with one of its most iconic images.
Caldwell 104 is just one of about 150 globular clusters in the Milky Way galaxy.
Hubble's image of Caldwell 6, better known as the Cat’s Eye Nebula, reveals intricate shells of gas and dust.
The objects in Charles Messier’s catalog are nice targets for backyard astronomers with a pair of binoculars or a small telescope and a relatively dark sky.
The Messier catalog, begun by astronomer Charles Messier in the 18th Century and revised over the years, includes some of the most fascinating astronomical objects that can be observed from Earth’s Northern Hemisphere.
The Caldwell Catalog goes beyond the work of Charles Messier, offering backyard astronomers more cosmic wonders to explore.
In the 1980s, an Englishman named Sir Patrick Moore produced an additional list to highlight more cosmic wonders visible to amateur astronomers. Unlike the Messier catalog, which only features objects that were visible from Charles Messier’s viewing location in Europe, Moore’s Caldwell catalog includes celestial bodies that are found in both the northern and southern skies.
The Bubble Nebula (Caldwell 11, NGC 7635) is the result of an extremely bright, massive, and short-lived star that shed most of its outer hydrogen and is now fusing helium into heavier elements. The star is about 4 million years old, and in 10 million to 20 million years, it will likely detonate as a supernova.
