Gallery: New Telescope Opens Big Eye to Southern Skies
01messier-17-the-swan-nebula
Looking up from Chile’s arid Atacama Desert, home to some of the clearest starscapes on Earth, a massive new telescope has taken its first breathtaking photos of the southern night sky. The [VLT Survey Telescope](http://www.eso.org/public/teles-instr/surveytelescopes/vst.html), or VST, uses a 268-megapixel camera. Over the next five years it will capture 150 terabytes worth of visible-light data, supplement existing surveys and help astronomers study the universe in fresh detail. On June 8, astronomers released the first two VST images. One is a 660-megabyte portrait of the Swan Nebula (above). The other is an equally detailed shot of Omega Centauri, a star-rich globular cluster sometimes called the jewel of the southern night sky. In this gallery we’ll show you the telescope and what it took to create these colossal space photos. *Image: ESO/INAF-VST/OmegaCAM \[[high-resolution version available](http://www.eso.org/public/images/eso1119a/)\]*

OmegaCAM -------- At the heart of the VST is a nearly 1-ton camera called OmegaCAM (above). It uses a 268-million-pixel bed of image sensors (below) to take highly detailed images.

Surveying the Night Sky ----------------------- Astronomers will use the telescope to make three highly detailed surveys of the southern sky. The target regions are color-coded here in red, green and blue. *Image: ESO \[[high-resolution version available](http://www.eso.org/public/images/allsky-vst/)\]*

Omega Centauri -------------- The second photo snapped by VST includes more than 300,000 stars in the Omega Centauri globular cluster. *Image: ESO/INAF-VST/OmegaCAM \[[high-resolution version available](http://www.eso.org/public/images/eso1119b/)\]*
