NASA has released more than 50 new Hubble images featuring 30 galaxies, star clusters and nebulae. All these objects belong to a collection known as the Collectwell Catalog of Astronomers.
During the 18th century, French astronomer Charles Messier produced a list of about 100 dispersed objects, which were difficult to distinguish from comets through the daytime telescope.
These foggy spots on the sky have since appeared in the form of distant galaxies, star clusters, and nebulae, and their catalog became a guide to explore visually stunning cosmic objects.
In the 1980s, British amateur astronomer and science communicator Sir Patrick Caldwell-Moore prepared an additional list to highlight the more cosmic wonders visible to amateur astronomers.
Unlike the Messier catalog, which only displays objects visible from Messier’s place of view in Europe, the Caldwell catalog includes celestial bodies that are found in both northern and southern neighborhoods.
It has a total of 46 star clusters, 35 galaxies and 28 nebulae or a total of 109 objects.
Caldwell-Moore deliberately avoided including any Messier objects in his catalog, hoping to expand the cosmic horizons of his fellow amateur astronomers.
From clouds surrounding gas and dust to distant galaxies away from the dying stars that formed billions of years ago, the Caldwell Catalog is working with astonishing celestial treatments.
The newly released collection of over 50 new Hubble images contains 30 Caldwell objects.
“Because of Hubble’s wide field, some of its photographs do not capture the entirety of the Caldwell object, sometimes instead of zooming in on clusters of young stars in the arms of a spiral galaxy, stars on the exterior of a cluster, or a Zombie star in the heart of the nebula, ”NASA astronomers said.
“But in other cases, a mosaic of Hubble commentaries gathers together to form a complete or nearly complete picture of the celestial miracle.”
Hubble’s collection now includes 87 of 109 Caldwell items.
“For each list in Hubble’s Caldwell catalog, an original star chart shows observers when and where they can find it in the night sky, and a description of what kind of observation tool they used to see it Can go, ”the researchers said.
“Personal articles also explain Hubble’s images for those who only like to enjoy exquisite views of the telescope.”
