NASA has unveiled 25 original space images on the anniversary of the Chandra X-Ray Observatory’s founding.

They include all forms of objects that the telescope has captured over the twenty five years of observation.

X-rays are one of the most powerful type of light that can detect objects that are extremely hot and physical processes that are very active. These include supernovae remnants such as Cassiopeia A, H II regions such as the Orion Nebula, and the central region of the Milky Way.

This montage also has objects outside our own Milky Way galaxy including other galaxies and galaxy clusters.
