NGC 5189 imaged at Gemini South. NGC 5189, a chaotic-looking planetary nebula that lies about 550 parsecs (1,800 light-years) away in the southern hemisphere constellation Musca, is a parallelogram-shaped cloud of glowing gas. The GMOS image of this nebula shows long streamers of gas, glowing dust clouds, and cometary knots pointing away from the central star. Its unruly appearance suggests some extraordinary action at the heart of this planetary nebula.
Gemini's Laser Vision Reveals Striking New Details in Orion Nebula This composite image at infrared wavelengths was obtained using the Gemini North laser guide star system in conjunction with the ALTAIR adaptive optics system and the NIRI near-infrared imager. The image shows the Orion "bullets" as blue features and represents the light emitted by hot iron (Fe) gas. The light from the wakes, shown in orange, is from excited hydrogen gas.

Millions of years ago, a dust cloud about 5,200 light-years from the Sun coalesced to begin the process of star birth. Today, some 190 million years later, NGC 6520 is ablaze with hot, massive young stars arrayed in a dandelion seed-shaped cluster. Not far away lies the gecko-shaped remains of what may be their birth cloud, Barnard 86. This image, taken using the Gemini Multi-Object Spectrograph on Gemini South, shows details in a 9.7- x 5.4-arcmin section of a larger, highly populated region in the Sagittarius star cloud.
Gemini South Image of the planetary nebula NGC 246 NGC 246 is a planetary nebula that lies about 1,600 light-years away in the constellation Cetus. Its central star shines at 12th magnitude and is whisking through space at about 80 kilometers (50 miles) per second.
NGC 6164-5 imaged at Gemini South. The emission nebula NGC 6164-5 is a rectangular, bipolar cloud with rounded corners and a diagonal bar producing an inverted S-shaped appearance. It lies about 1,300 parsecs (4,200 light-years) away in the constellation Norma. The nebula measures about 1.3 parsecs (4.2 light-years) across, and contains gases ejected by the star HD 148937 at its heart. This star is 40 times more massive than the Sun, and at about three to four million years of age, is past the middle of its life span.

Color composite adaptive optics image of the planetary nebula M2-9 using the ALTAIR adaptive optics system on Gemini North. This image reveals remarkable details in the dynamic gas outflows from a dying star. It is thought that our Sun might meet a similar fate in 4-5 billion years once its hydrogen nuclear fuel becomes scarce and instabilities expel gas into space. The concentric shells of gas are still a mystery to astronomers and these data will help to understand the complexities surrounding this beautiful object.
Gemini South image of dragon-like dark nebula NGC 6559 NGC 6559 is a relatively small, nearby dust cloud in our Milky Way galaxy that measures about seven light-years across. NGC 6559 is part of a larger star-forming region in the southern constellation Sagittarius. The dark structure that resembles a Chinese dragon is caused by cool dust that absorbs background radiation from hydrogen gas that glows in red light due to ionization from nearby stars.
Gemini North image of stellar nursery RY Tau was imaged by the Gemini Multi-Object Spectrograph (GMOS) as part of a Canadian contest for amateur astronomers. The image reveals tremendous detail in the wispy remains of the gas cloud that formed the bright star at bottom/center. This system is approximately 140 parsecs (450 light years) away, and spans about 2/3 of a light year. The central star is a variable star that ranges between visual magnitudes 9 and 11 over an irregular period of time.
