Peruse Hubble Images of Beautiful Astronomical Objects

This year, the popular Hubble space telescope turned 30 years old. It was introduced in 1990 and has helped us understand the expansion of the universe. It has enabled us to view objects far beyond our solar system.

Now NASA has updated their Hubble Caldwell catalog, a collection of the most beautiful images Hubble has captured over the years. The Caldwell Catalog Project, which began in 1995, was a list originally compiled by astronomer Sir Patrick Caldwell-Moore to supplement the traditional Messier Catalog, which lists astronomical objects that are visible in the sky. The Caldwell catalog contains 109 objects, including galaxies, nebulae, and star clusters, that are visible to amateur astronomers.

For astronomers who want to refer to very detailed images of the objects they are observing, or simply for those who love to enjoy breathtaking images of space, the Hubble Caldwell catalog shows all of these objects in exquisite detail as well as a map of where everyone is in the night sky.

We’ve released some of our favorite additions to the catalog below, including dusty nebulae, distant galaxies, and bright star clusters:

This beautiful Hubble image captures the core and some of the spiral arms of the galaxy Caldwell 36.  This spiral galaxy, also known as NGC 4559, is located in the constellation Coma Berenices about 30 million light years from Earth.

Galaxies are made up of a number of different structures, and the details of these structures drive the evolution of a particular galaxy.  One such structure in spiral galaxies like Caldwell 40 (or NGC 3626) is the galactic bulge.  This structure is a densely packed region of stars that encompasses the heart of a spiral galaxy.Galaxies are made up of a number of different structures, and the details of these structures drive the evolution of a particular galaxy.

This Hubble image shows Caldwell 78 (or NGC 6541), a globular cluster about 22,000 light years from Earth.  The cluster is bright enough that backyard stargazers in the southern hemisphere can easily spot it with binoculars.This Hubble image shows Caldwell 78 (or NGC 6541), a globular cluster about 22,000 light years from Earth.
