RCW 108, also called the Rim Nebula,^[1] is a large star formation in the Milky Way, about 4,000 light years from Earth. RCW 108 is part of the Constellation Ara.^[2] is in the process of being destroyed by intense light which radiates from a star inside of NGC 6193. NGC 6188 has an angular extent of 20.0' × 12.0', and has been heavily documented by multiple telescopes, including Chandra and Spitzer.^[3]
