Description

This collection of objects, located only 500 light years away in the southern constellation of Corona Australis, is one of my favorites. Among the objects included in this field of view are a huge dust cloud, a star cluster, several reflection nebulae and a number of Herbig-Halo objects, all in front of a dense backdrop of colorful stars. This is a beautiful star-forming region. I am not sure who gave this object its nickname, but I love it. The dust cloud is shaped like an anteater with a huge snout lumbering to the right across the sky.

The globular star cluster at upper right is NGC 6723. It is much further away than the other objects, at a distance of 30,000 light years. The blue reflection nebulae at the center of the image are NGC 6726 (top) and IC 4812 (bottom). The bottom reflection nebula is powered by a bright blue double star which can be seen by looking closely. NGC 6729 is the white reflection nebula at the center of the image. It is a variable nebula, illuminated by the irregular variable star, R Coronae Australis. The dark nebulae that extend through the image are primarily Bernes 157 and 158. The dust is so thick that it completely blocks visible starlight at its center.

Several tiny reddish Herbig-Haro objects are visible, including HH100 (immediately right of the white reflection nebula) and HH101 (left of the bottom blue reflection nebula). Many other HH objects are present in this region but not visible in the image.

Although not given designations to my knowledge, a number of other bright stars in the image are surrounded by small reflection nebula due to the large amount of dust in this region.

At -37 degrees declination, this object is a tough one for many of us in the Northern Hemisphere to capture.
