30 years later, Hubble is still making bright discoveries

With 30 additional images, Hubble’s collection now includes 87 of the 109 Caldwell items. One of the more dramatic images seen at the top is Caldwell 45, or NGC 5248, a spiral galaxy located in the constellation Boits, noted for its ring structure around the nucleus.

This particular image, among others in the Caldwell catalog, is produced from several Hubble devices including Wide Field Camera 3 and Wide Field and Planetary Camera 2 in visible, infrared, and ultraviolet light. According to NASA, “it captures the glowing red clouds where new stars are forming, scattered along the curved arms of the galaxy.” “These observations … were made to help astronomers learn more about the gas in the starburst regions of the galaxy, as well as to better understand the structure of its atomic rings.”

Although you may not have access to such sophisticated equipment, you can actually see this cluster using a small telescope, “although it won’t look too bright,” NASA said. NASA shows a chart in which you can roughly find it and the best time to see it (during summer), and other sites Go astronomy Show more accurate celestial coordinates. The beauty of star catalogs such as Caldwell and Messier is that they help you see these incredible objects by themselves, sometimes with just a pair of binoculars or even an eyeball.

NASA tasked Hubble with five more years of service in 2016, but the estimate is fluid. “There is no set date for Hubble’s retirement. Hubble will continue to operate as long as its components work and it provides a good service to the scientific community, ”the European Space Agency website states. Considering the discoveries so far, it is expected that it will be another 30 years.
