A 'cosmic candy cane' at the center of the Milky Way could hold clues to star formation, NASA says

(CNN)A new image of the Milky Way shared by NASA scientists Thursday has revealed a festive-themed feature -- a "cosmic candy cane" that holds the raw materials for tens of millions of stars.

The composite image shows our galaxy's central zone, which has the largest and densest collection of giant molecular clouds in the galaxy. These clouds are huge and cool in temperature, with enough dense gas and dust to create tens of millions of stars like the sun, according to NASA.
At the center of the image is the easily discernible candy cane shaped feature. It spans 190 light-years and is one of a set of long, thin strands of ionized gas called filaments that emit radio waves, NASA said in a news release.
    Flares of red, yellow and turquoise, arcs of blue and green, and faint spots of light appear in the image, which was captured by NASA's Goddard-IRAM Superconducting 2-Millimeter Observer (GISMO) camera, along with a 30-meter radio telescope.
    "We're very intrigued by the beauty of this image; it's exotic," said Johannes Staguhn of Johns Hopkins University, who led a paper describing the image, published in the Astrophysical Journal. "When you look at it, you feel like you're looking at some really special forces of nature in the universe."
    Our solar system is a small part of the Milky Way galaxy, a collection of stars, gas and dust bound together by gravity and named for its appearance from Earth as a milky band of light in the sky, according to NASA.
    "There's a good chance that a significant part of star formation that occurred during the universe's infancy is obscured and can't be detected by tools we've been using, and GISMO will be able to help detect what was previously unobservable," said Staguhn in a press release.
    The colorful image also identified several key features -- like landmarks on a terrestrial map. There's one feature called the Sickle, which is associated with star formation. There's Sagittarius A, an extremely bright red-yellow region about 27,000 light years away from us. And there's the Radio Arc, a bright red curve that cuts through the Sickle, and forms the "straight part of the cosmic candy cane."
