Scientists at NASA have just published a set of newly obtained images of nebulae taken in 2012 and 2013 by NASA's Chandra X-Ray Observatory. This
particular image shows a uniquely shaped emission nebula NGC2013-0401, also called "Phantom Nebula", located in the small Southern constellation
Phantom Nebula is an example of an emission nebula - a cloud of interstellar gas illuminated by a nearby star whose radiation ionizes the gas and
makes it glow. The star is clearly visible in the centre of the image.
"We have identified several nebulae with very unique shapes," says the British astronomer Chris Keegan who has been working with Chandra images for
several years. "We don't yet have a good understanding of what is causing such unusual shape. There may other objects we haven't yet detected whose
presence causes the gaping holes in the gas cloud. We expect more detailed data in the next few months."
