SNR 0103-72.6: Oxygen Supply

Explanation: A supernova explosion, a massive star's inevitable and spectacular demise, blasts back into space debris enriched in the heavy elements forged in its stellar core. Incorporated into future stars and planets, these are the elements ultimately necessary for life. Seen here in a false-color x-ray image, supernova remnant SNR 0103-72.6 is revealed to be just such an expanding debris cloud in neighboring galaxy, the Small Magellanic Cloud. Judging from the measured size of the expanding outer ring of shock-heated gas, about 150 light-years, light from the original supernova explosion would have first reached Earth about 10,000 years ago. Hundreds of supernova remnants have been identified as much sought after astronomical laboratories for studying the cycle of element synthesis and enrichment, but the x-ray data also show that the hot gas at the center of this particular supernova remnant is exceptionally rich in neon and oxygen.

Speaking of "Lights of Zetar:" Why is it that every time Scotty had a love interest she was either killed, possessed, or both?
Just curious.

Right you are - the dancer he was attracted to in "Wolf in the Fold" died pretty quickly. Although the gal in "Who Mourns for Adonis" managed to survive to the end of the episode unscathed. Ladies, stay away from Scotty!

Yes, the WMfAdonis gal lived, but Scotty died in the episode. I forget -- did Apollo restore him to life? It's been too long since I've watched real Star Trek.

LOL! Yep, Scotty died or close to it.
I really need to get a life

Yes, I do. You are now a proud member of the APOD ping list! Thanks. Got pinged today.
Really a fine thread to keep going. I may share it with my home schooler progeny.

I really need to get a life"Get a life!" - isn't that what Bill Shatner said to the Trekkie convention on that Saturday Night Live skit? And how about the "Restaurant Enterprise"? Classic comedy.
