A new image, taken by VLT Survey Telescope at European Southern Observatory's (ESO) Paranal Observatory in Chile, gives us a detailed look at the drama surrounding Ara's region, according to a press release from ESO.
The open star cluster NGC 6193 is the heart of the Ara OB1 association with thirty bright stars, two of which are very hot giants. The giant stars illuminate the neigboring emission nebulae, the Rim Nebula, also known as NGC 6188 (visible to the right of the bright center).
"This single spectacular image was actually created from more than 500 individual pictures taken through four different color filters with the VLT Survey Telescope," according to the press release. "The total exposure time was more than 56 hours. It is the most detailed view of this region yet achieved."
