Trifid Nebula in Sagittarius Coaster
This image composite compares visible-light and infrared views from NASA's Spitzer Space Telescope of the glowing Trifid Nebula, a giant star-forming cloud of gas and dust located 5,400 light-years away in the constellation Sagittarius. Visible-light images of the Trifid taken with NASA's Hubble Space Telescope show a murky cloud lined with dark trails of dust. Data of this same region from the Institute for Radioastronomy millimeter telescope in Spain revealed four dense knots, or cores, of dust (outlined by yellow circles), which are "incubators" for embryonic stars. Astronomers thought these cores were not yet ripe for stars, until Spitzer spotted the warmth of rapidly growing massive embryos tucked inside.

Beautiful horse drawing on this coaster makes it a great conversation piece. Artist is very talented! The printing Zazzle did is nice and crisp, but not as black as I would have liked and the edges had some execess on them But some sandpaper fixed the issue

I'm not sure how much moisture these will soak up, haven't had a chance to try them out, but they look good and I like the cork backing. The printing is fine ~ and really looks cool with an artisan's hand made "Hurricane Martini" glass sitting on top of my painting (on the coaster) in my studio.
