Green Ghost
Astronomy is abuzz with discovery by 25-year old Hanny van Arkel of a galaxy unlike any ever found. The Dutch schoolteacher found this strange object while participating in the Galaxy Zoo. This project invites anyone to classify galaxies from the vast Sloan Digital Sky Survey database. Hanny will likely be named a co-discoverer, increasing respect for "amateur" astronomers.
This hot green ring of gas is a starless galaxy, radiating from an unseen energy source. The object radiates with a greater intensity and temperature than could be accounted for by normal means. The central void in this object would be an excellent placed to seek a Black Hole. There could be many more dark objects out there. The 71.62% of the Universe ascribed to "dark energy" may be hidden in the voids.

What a beautiful image! With the amount of data being collected nowadays, there is more than enough work for any keen astronomers. I was working yesterday with a knowledgeable 'amateur' Eeva (unspellable Finnish surname) at the Astro Cafe here at Mt John observatory.
It was good to hear that you are at an observatory. You are much closer to the universe than most physicists. Like Newton's exile from Cambridge during the plague, or Einstein's stint in the parent office, this could lead tro new insights.
Could this starless galaxy possibly be a look into what galaxies and galaxy formation was like shortly after the Big Bang, before the birth of stars?
Oh holy heck. That is obviously the gaseous energy being that attacked the USS Enterprise in that one TOS episode.
nice
