Peruse Hubble images of beautiful astronomical objects visible in the night sky

This year, the beloved Hubble Space Telescope turned 30. Launched in 1990, it has been instrumental in helping us understand the expansion of the universe and has allowed us to peer out at objects far beyond our solar system.

Now, NASA has updated its Hubble Caldwell catalog, a collection of some of the most beautiful images Hubble has captured throughout the years. The Caldwell catalog project, which began in 1995, was a list originally compiled by astronomer Sir Patrick Caldwell-Moore as an addition to the traditional Messier catalog which lists astronomical objects that can be seen in the sky. The Caldwell catalog contains 109 objects including galaxies, nebulae, and star clusters which are visible to amateur astronomers.

For astronomers who want to refer to highly detailed images of the objects they’re observing, or simply for those who love to enjoy stunning images of space, the Hubble Caldwell catalog shows all of these objects in exquisite detail, as well as a map of where in the night sky each is located.

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

Caldwell 29, also known as NGC 5005, is a spiral galaxy that likely harbors a supermassive black hole at its heart.

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

Galaxies consist of a number of different structures, and the particulars of these structures drive the evolution of a given 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.

This Hubble image captures Caldwell 78 (or NGC 6541), a globular star cluster roughly 22,000 light-years from Earth. The cluster is bright enough that backyard stargazers in the Southern Hemisphere can easily spot it with binoculars.
