Giant Soap Bubble In Space

What looks like a giant soap bubble or even perhaps just a water drop on a camera lens is actually a newly discovered planetary nebula. Dave Jurasevich of the Mount Wilson Observatory in California spotted the “Cygnus Bubble” while recording images of the region in July 2008. A few days later, amateur astronomers Mel Helm and Keith Quattrocchi also found it. Then, in 2009, the Kitt Peak Observatory pointed its 4-meter Mayall telescope at the object, and created the image above. Spectacular!

The bubble has been there awhile, and probably won’t “pop” anytime soon. The object was officially named PN G75.5+1.7 just last week. Astronomers have looked back at older images and found the object, just barely discernible in some images, such as this image below taken by Jurasevich.

Faint "Bubble" Nebula in Cygnus - Imaged on 05 July 2008 by Dave Jurasevich

A closer look at images from the second Palomar Sky Survey revealed it had the same size and brightness 16 years ago. Jurasevich thinks it was overlooked because it is very faint.

“It’s a beautiful example,” says Adam Frank of the University of Rochester, New York. “Spherical ones are very rare.” One explanation is that the image is looking down the throat of a typical cylindrical nebula. However, it is still remarkably symmetrical, Frank says.

    Oh wow, that is really amazing and beautiful.

    I forgot my empty beer glass on the telescope.

    Additional images , links, and info on this beautiful object by Keith Quattrocchi can be found here: http://www.lostvalleyobservatory.com/page29crescentbubblenb/ . Quite interesting to find a 260″-diameter planetary nebula within a half degree of NGC 6888 (‘Crescent Nebula’) ! Astroimagers with deep pics of this region may be rewarded by double-checking their images.

    Looks like an awesome planetary nebula, but maybe it’s just an artificial atmosphere created by aliens.

    MikeArms24: Haha no, silly! It’s obviously a unusually large Dyson Sphere! =P

    Astonishing.

  7. Shaula Brandt says

    From the earlier picture to the most recent, has there been an expansion rate calculated for this object?

    Dyson Sphere….wouldn’t that be a hoot! I wonder how long it will be before they get the exterior cladding on it installed…lol???!!!

    Stunning. Amazing to think that is this age of digitized sky surveys and truckloads of amateur imaging, an object like this could go unnoticed in a constellation such as Cygnus!
