Merry Sciencemas


Hubble Space Telescope image of the planetary nebula NGC-5189, located some 3,000 light years from Earth in the constellation Musca. It is though to be created from a dying binary, or two star system. NASA released the image for the holidays because it resembles an ornament.

No, this image is not one of the Mayan apocalypse. NASA has a tradition of releasing spectacular Hubble images in time for the winter holidays, such as a 2011 photo of a space “snow angel,” and 2012 was no different.

This year, NASA published a breathtaking photo of a planetary nebula called NGC-5189, located some 3,000 light years away in the constellation Musca (the fly).

Nebulas like the one shown here are formed by dying stars — ones like our own Sun except that have run out of fuel and are ejecting their outer layers, which become superheated by the remaining stellar material and billow outward as clouds of gas, turning into beautiful patterns and shapes. The nebula pictured, NGC-5189, is said to resemble a “glass-blown ornament,” according to NASA, hence it being featured as this year’s holiday favorite.
Because I am an Old and to support the Post Office, I send out actual holiday cards on paper, with stamps and everything.  NASA needs to start a line of holiday cards with Hubble photos on them, and the explanation of the image on the inside.  All of us who remember the Apollo missions would snatch them up.
