BHR 71 (also Sandqvist 136 ) is a small, dark nebula in the constellation of Fly . The nebula is about 600 light years from Earth and covers an area of about one light year.
In visible light, BHR 71 appears as a large black spot. In the infrared range , however, you can see two young stars, both of which shoot out green strands. These green strands are the beginning of a jet , which consists of oxygen and is very hot. With greater distance, the energy sinks and the color of the jet shifts from orange to red. In a combined image of infrared and visible images, one recognizes that an outbreak of the one young star is responsible for the breakdown in visible light.
