\n This ethereal image, captured from Chile by the international Gemini Observatory, a program of NSF’s NOIRLab, looks as delicate as a butterfly\u2019s wing. It is, however, a structure known as the Chamaeleon Infrared Nebula, which is located near the center of the mammoth Chamaeleon I dark cloud, one of the nearest star-forming regions in our Milky Way.

This breathtaking visible-light image, taken with the Gemini South telescope, looks as though it is ready to flutter off the screen. This app<\/a>arently wispy object is an outflow of gas known as the Chamaeleon Infrared Nebula\u2014so named because it is bright at some infrared wavelengths of light, although it can also be seen in visible light, as in this view. Hidden at the core of this reflection nebula, and at the center of this image, is the engine of the nebula, a low-mass star (less massive than our sun) that is eclipsed by a dark vertical band. Even though it is concealed from view, this young, cool star emits streams of fast-moving gas that have carved a tunnel through the interstellar cloud from which the young star formed. Infrared and visible light emitted by the star escapes along this tunnel and scatters off its walls, giving rise to the wispy reflection nebula.<\/p>\n

\n <\/p>\n<\/section>\n

The bright red object to the right of the image center marks where some of the fast-moving stream of gas lights up after colliding with slower-moving gas in the nebula. It is known as a Herbig-Haro (HH) object and has the designation HH 909A. Other Herbig-Haro objects have been found along the axis of the star’s outflow beyond the edges of the image to the right and left.<\/p>\n

Astronomers have suggested<\/a> that the dark band at the center of the Chamaeleon Infrared Nebula is a circumstellar disk\u2014a reservoir of gas and dust orbiting the star. Circumstellar disks are typically associated with young stars and provide the materials needed to build planets. The reason the disk appears as a band rather than a circle in this image is because it is edge-on, only revealing one edge to observers here on Earth. Astronomers believe that the nebula’s central star is a young stellar object embedded within the disk. <\/p>\n

The background nebulosity, appearing in blue in this image, is reflecting light from a nearby star located outside the frame.<\/p>\n
