![]() ![]() The APEX observations used in this image were led by Thomas Stanke (ESO), Tom Megeath (University of Toledo, USA), and Amy Stutz (Max Planck Institute for Astronomy, Heidelberg, Germany). While the lower regions in this image contain only low-mass young stars, NGC 2071 contains a more massive young star with an estimated mass five times that of the Sun, located in the brightest peak seen in the APEX observations. Their presence is therefore evidence that these clumps are actively forming stars.Īt the top of the image is another reflection nebula, NGC 2071. These outflows are ejected from young stars while the star is still forming from the surrounding cloud. Observations of the gas in these clouds reveal gas flowing at high velocity out of some of the dense clumps. The lack of a corresponding dark dust lane in the visible light image tells us that this dense region of dust must lie behind the reflection nebula. M78 is located approximately 1,600 light-years away from Earth and has an apparent magnitude of 8. ![]() ![]() A reflection nebula is created when light from a star is scattered or reflected off a nearby dust cloud. Another prominent region of glowing dust seen by APEX overlaps with the visible light from Messier 78 at its lower edge. This colorful image features a small part of M78, a reflection nebula located in the constellation Orion. This tells us that the dense dust lies in front of the reflection nebula, blocking its bluish light.

One filament seen by APEX appears in visible light as a dark lane of dust cutting across Messier 78. In visible light, this dust is dark and obscuring, which is why telescopes such as APEX are so important for studying the dusty clouds in which stars are born. Sensitive to longer wavelengths, they reveal the gentle glow of dense cold clumps of dust, some of which are even colder than -250✬. The APEX observations are overlaid on the visible-light image in orange. When seen in visible light, this region is a reflection nebula, meaning that we see the pale blue glow of starlight reflected from clouds of dust.
