Since its launch in 1990, the Hubble Space Telescope has made outstanding contributions to scientific exploration and has become an important window for us to open our eyes. Today, NASA released 30 new images of the Caldwell catalog, which includes glittering star clusters, ghost nebulae and magnificent galaxies.
"These photos were taken by Hubble throughout his career for scientific research or engineering testing, but until now, NASA has not fully processed them for public release," NASA said in a statement this week. There are 109 objects in the Caldwell directory, and Hubble has now collected 87 of them.
