Your Cosmos Cure for Debate Hangover

My brain is too tired of debate talk this morning – so if you’re in the same situation, you can join me in the best sort of brain re-energizing there is:  gazing at the Cosmos!

Today’s Astronomy Picture of the day from NASA is the great Helix Nebula:

The Amazing Helix Nebula

Amazing, isn’t it?  Like a giant blue eye staring back at us.

Explanation from NASA:

A mere seven hundred light years from Earth, in the constellation Aquarius, a sun-like star is dying. Its last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution. A total of 58 hours of exposure time have gone in to creating this deep view of the nebula. Accumulating narrow band data from emission lines of hydrogen atoms in red and and oxygen atoms in blue-green hues, it shows remarkable details of the Helix’s brighter inner region, about 3 light-years across, but also follows fainter outer halo features that give the nebula a span of well over six light-years. The white dot at the Helix’s center is this Planetary Nebula’s hot, central star. A simple looking nebula at first glance, the Helix is now understood to have a surprisingly complex geometry.

Feel better now?  I know I do.
