Hubble’s Caldwell CatalogHubble has captured images of many objects in the Caldwell catalog that you can view yourself with a backyard telescope.Stars with four diffraction spikes dot the scene against a black backdrop.Hubble’s Wide Field and Planetary Camera 2 (WFPC2) captured images of stars in other parts of Caldwell 1 (NGC 188)....This image of Caldwell 2 (C2) was taken in 1995 as part of a survey of nearby planetary nebulae. Astronomers...This image of Caldwell 2’s central star was taken in 2009 using Hubble’s Wide Field Camera 3. The observation was...This barred spiral galaxy was first spotted by British astronomer William Herschel in April 1793 in the constellation Draco.Also called the Iris Nebula, or NGC 7023, Caldwell 4 is of particular interest to astronomers.Though bright, this spiral galaxy is very difficult to find in the crowded sky area near the Milky Way's disk.Searching for visible-light counterparts to X-ray sources detected by NASA’s Chandra X-ray Observatory, astronomers used Hubble’s Advanced Camera for Surveys...Caldwell 6 is also known as NGC 6543, but is commonly called the Cat’s Eye Nebula.This closer view of billowing clouds of gas around the dying star at the center of the Cat’s Eye Nebula...Supernova hunters may be familiar with Caldwell 7 as the galaxy hosted a supernova in 2004.Also called the Cave Nebula, Caldwell 9 is an area where new stars are forming.Better known as the Bubble Nebula, Caldwell 11 is a colorful region of gas and dust that stretches 6 light-yearsHubble captured this image of Caldwell 11’s central star and one edge of the nebula’s “bubble” with the telescope’s original...This image of spiral galaxy NGC 6946 (Caldwell 12) is one of a dozen previously unreleased images in the new...Astronomers have used Hubble’s Wide Field and Planetary Camera 2 (WFPC2) and Wide Field Camera 3 (WFC3) to study a...This infrared image of Caldwell 12’s core was captured by Hubble’s Near Infrared Camera and Multi-Object Spectrometer. The red clouds...These two bright star clusters appear side by side in the northern sky.A blinking remnant star, called a white dwarf, sits at the heart of this colorful nebula.Also known as NGC 147, Caldwell 17 is a dwarf galaxy in our local group of galaxies.In the upper right, a ground-based image from the Digitized Sky Survey (DSS) shows Caldwell 17 (NGC 147). A white...In the ground-based Digitized Sky Survey (DSS) image at upper right, a blue outline shows another area of Caldwell 17...Caldwell 18 is a nearby galaxy in the local group with an active galactic nucleus.The ground-based image of Caldwell 18 (NGC 185) in the top left is from the Digitized Sky Survey (DSS) and...While the spiral feature in the upper portion of this Hubble image may resemble the arm of a galaxy or...Discovered in 1788 by astronomer William Herschel, Caldwell 21 is dwarf irregular galaxy bursting with forming stars.This image was taken using Hubble’s Wide Field and Planetary Camera 2 in 2000. Astronomers compared this image to earlier...Sir Patrick Moore, creator of the Caldwell catalog, once said that Caldwell 23 looks like “two fried eggs clapped back...This image, taken with Hubble’s Near Infrared Camera and Multi-Object Spectrometer in 1998, showcases the center of Caldwell 23 (NGC...The tendrils that reach out beyond the elliptical galaxy Caldwell 24, also called C24, are the only visible-light manifestation of...This close-up view of the center of Caldwell 24, combining visible and infrared observations taken by Hubble’s Wide Field and...Dubbed "the Intergalactic Wanderer,” Caldwell 25 is different from the Milky Way's other globular clusters.Also called NGC 4244 and the Silver Needle Galaxy, Caldwell 23 is part of the same galactic super cluster as...Commonly called the Crescent Nebula, Caldwell 27 looks more like a prehistoric dinosaur egg. Hubble’s vibrantly colored image zooms in...Caldwell 29, also known as NGC 5005, is a spiral galaxy that likely harbors a supermassive black hole at its...A white circle shows the location of supernova SN 2014C observed in Caldwell 30.The majestic spiral galaxy Caldwell 30, also cataloged as NGC 7331, is often touted as an analog to our own...This stream of stars embedded in cosmic clouds is part of Caldwell 32, also cataloged as NGC 4631 and commonly...Caldwell 33 is part of an extensive supernova remnant known as the Veil Nebula (or the Cygnus Loop). Caldwell 33...This image, taken with Hubble's Wide Field and Planetary Camera 2, shows another small part of Caldwell 33. The colors...
