In April 1990, our universe opened up to us in a whole new way.
At the same time that the Hubble Space Telescope was launched and deployed, the most powerful space telescope ever was built.
Although the tool started out with difficulty, Hubble has been in operation for a full three decades until April this year. And, in celebration of this marvelous landmark, NASA has just given us a wealth of space: 50 new processed images of proces budgets from the Caldwell catalog, unveiled to the public for the first time.
Cosmic objects can be classified in many different ways. What makes the Culdwell catalog special is that it contains only objects that can be observed by backyard astronomers. Grab a telescope (or, in some cases, your own two eyes) and you can find these things for yourself in the night sky.
The Killedwell catalog, compiled by amateur astronomer and author Sir Patrick Alfred Cuddwell-Moore, was first published in 1995. Sky and telescope, Built as a complement to the Messier catalog of 110 of Buzzets compiled by French astronomer Charles Messier in the 18th century.

Messier, famously, made his list out of despair. He was interested in finding comets; The list was a list of annoying things Were not Comets, and so they can be safely ignored by comet hunters.
Ironically, it became a really useful list of bright targets for amateur astronomers to see, including nebulae, constellation clusters, and nearby galaxies.

The Caldwell catalog, which contains 109 containing objects, includes 28 nebulae, 46 clusters, and 35 galaxies, not included in the Messier catalog, but still a keen interest for anyone who enjoys the skyward at night.
It’s a pleasure to find these objects yourself, and to see them light-years away from your eyes. It’s also a pleasure to compare your own observations that Hubble saw through his more powerful “eye”. And, well, they’re just gorgeous.
The 30 new NASA images feature 30 Caldwell objects, with some objects appearing in more than one image.

“Because of Hubble’s detailed view, some of its images do not capture the completeness of a well-worn object object, sometimes hovering over a cluster of young stars in the hands of a spiral galaxy, stars on the outer edge of a cluster or” zombie star in the center of a nebula, “the NASA website. Wrote Vanessa Thomas of the Center.
“But in other cases, mosaics of Hubble observations come together to create a complete or almost complete portrait of a celestial miracle.”
In total, Hubble’s Caldwell catalog – first published in December 2019 – now contains 87 of the 109 Caldwell objects. The Space Telescope did not ignore the Messier catalog, either; Hubble has made 96 images out of 110 Messrs. Of Buzzets. Each of the two catalogs includes a guide on how to see it in the sky.

Together, the two collections contain some of the most amazingly beautiful images of the space around us – a wonderfully inspiring tour of the wonders of the universe.
And the priceless treasure is Hubble’s absolute promise.
