Lose Yourself in 50 Breathtaking New Images Released For The Hubble Anniversary
In April of 1990, our Universe opened up to us in a whole new way.
That s when the Hubble Space Telescope was launched and deployed, the most powerful space telescope ever created.
Although the instrument got off to a bumpy start, Hubble has, as of April this year, been in operation for a full three decades. And, in celebration of this marvellous milestone, NASA has just handed us space riches: 50 newly processed images of objects from the Caldwell catalogue, released to the public for the first time.
Cosmic objects can be categorised in many different ways. What makes the Caldwell catalogue 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 objects for yourself in the night sky.

Leaving this planet for vacation may not be in the cards just yet (don’t worry, the option is coming), but you can at least mentally escape for a moment, thanks to a few stunning images captured by the Hubble Space Telescope over the last 30 years.
In 2020, the Hubble telescope turned 30. To mark the milestone, NASA released dozens of unseen images taken by the instrument over the years, including galaxies, star clusters, and nebulae.
However, as NASA noted, there’s something extra special about these images, and that is the fact that all the space objects can also be seen through backyard telescopes. Some, NASA added, can even be seen through binoculars or even the naked eye. “All of these celestial objects belong to a collection known to amateur astronomers as the Caldwell catalog,” NASA explained in a blog post

NASA has released more than 50 new Hubble images featuring 30 galaxies, star clusters, and nebulae. All of these objects belong to a collection known to astronomers as the Caldwell catalog.
This Hubble images shows Caldwell 45, a spiral galaxy located 59 million light-years away in the constellation Boötes. Also known as NGC 5248, this galaxy is notable for the ring structure around its nucleus. These nuclear rings are characterized by hot spots of starburst activity. Caldwell 45 was discovered by astronomer William Herschel in 1784. The galaxy has an apparent magnitude of 10 and can be spotted using a small telescope, though it won’t appear very bright. A larger telescope is needed to make out the galaxy’s spiral arms. The best time of year to observe Caldwell 45 is during the northern hemisphere’s spring and the southern hemisphere’s autumn. This stunning image of Caldwell 45 is a composite of observations made by Hubble’s Wide Field Camera 3 (WFC3) and Wide Field and P
