Nebula NGC 5189

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.

The Starry Dandelion and the Cosmic Gecko NGC 6520

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.

Jupiter's Red Spots

Gemini North adaptive optics image of Jupiter and its two red spots (which appear white because this is a near-infrared image; in visible light they appear reddish). In this color composite image, white indicates cloud features at relatively high altitudes; blue indicates lower cloud structures; and red represents still deeper cloud features. The two red spots appear more white than red, because their tops hover high above the surrounding clouds.

Nebula NGC 6164-5

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.
