The
Deep Space Objects
The
information and links below describe the specific Deep Space Objects
depicted on our Cosmic Decoders cards. If you want to find
general information about different types of cosmic objects (such
as planetary nebulae, spiral galaxies, etc.), click on the following

Deep Space Objects and Cosmic Terms. For more on telescopes

Many
objects in astronomy don’t have names, but are referred to by their
numbers in catalogs astronomers have compiled over the past few
centuries. In the lists below, "M numbers" refer to Charles
Messier’s list of interesting (fuzzy-looking) objects in the
sky (a list he compiled in the 18th century so he could avoid them
in his search for comets). "NGC numbers" refer to a much larger
19th century list, called the New
Galactic Catalog.
