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 stunning image captures a small region at the edge of the Ink Cabbage Sack Nebula, or Caldwell 99. NASA, ESA, and R. Sahai (Jet Propulsion Laboratory); Processing: Gladys Kober (NASA / Catholic University of America)
Caldwell 72, also known as NGC 55, is a galaxy located 6.5 million light years from Earth in the constellation Sculptor. NASA, ESA, R. de Jong (Leibniz Institute for Astrophysics Potsdam [AIP]) and G. Illingworth (University of California – Santa Cruz); Processing: Gladys Kober (NASA / Catholic University of America)
Caldwell 29, also known as NGC 5005, is a spiral galaxy that is likely to harbor a supermassive black hole in its heart. NASA, ESA and L. Ho (Peking University); Processing: Gladys Kober (NASA / Catholic University of America)
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. NASA, ESA and S. Smartt (Queen’s University of Belfast); Processing: Gladys Kober (NASA / Catholic University of America)
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. NASA, ESA and P. Erwin (Max Planck Institute for Extraterrestrial Physics); Processing: Gladys Kober (NASA / Catholic University of America)
Caldwell 45 or NGC 5248 is a spiral galaxy in the constellation Boötes and is characterized by the ring structure around its core. NASA, ESA, J. Lee (California Institute of Technology) and A. Filippenko (University of California – Berkeley); Processing: Gladys Kober (NASA / Catholic University of America)
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. NASA, ESA and G. Piotto (University of Padua); Processing: Gladys Kober (NASA / Catholic University of America)
