You are fabulous and an inspiration to us all.
kai, thx, bai

ABOUT THIS IMAGE:
The unique planetary nebula NGC 2818 is nested inside the open star cluster NGC 2818A. Both the cluster and the nebula reside over 10,000 light-years away, in the southern constellation Pyxis (the Compass).
NGC 2818 is one of very few planetary nebulae in our galaxy located within an open cluster. Open clusters, in general, are loosely bound and they disperse over hundreds of millions of years. Stars that form planetary nebulae typically live for billions of years. Hence, it is rare that an open cluster survives long enough for one of its members to form a planetary nebula. This open cluster is particularly ancient, estimated to be nearly one billion years old.
The spectacular structure of NGC 2818 (also known as PLN 261+8.1) contains the outer layers of a sun-like star that were sent off into interstellar space during the star's final stages of life. These glowing gaseous shrouds were shed by the star after it ran out of fuel to sustain the nuclear reactions in its core.
Planetary nebulae can have extremely varied structures. NGC 2818 has a complex shape that is difficult to interpret. However, because of its location within the cluster, astronomers have access to information about the nebula, such as its age and distance, that might not otherwise be known.
Planetary nebulae fade away gradually over tens of thousands of years. The hot, remnant stellar core of NGC 2818 will eventually cool off for billions of years as a white dwarf. Our own sun will undergo a similar process, but not for another 5 billion years or so.
This Hubble image was taken in November 2008 with the Wide Field Planetary Camera 2. The colors in the image represent a range of emissions coming from the clouds of the nebula: red represents nitrogen, green represents hydrogen, and blue represents oxygen.
I took this one on the very first night he came to live with me. He's squinting because this was pre-SLR and he wasn't liking the FLASHY-THINGY.
Poor kitteh- here he is the day he got shaved at the vet - his fur was so matted there was no way around it. He didn't seem to mind, but he sure did look silly.
This photo is about 6 weeks in - he'd survived the awful surgery, was recovering, getting healthy and enjoying a plethora of kitteh toys.
And this might be one of my all time favorite photos - not because it's such a great photo (it's not) but because of what he's doing in the picture. I took this while he was watching a show on Discovery Channel about Humboldt Squid. It was the damnedest thing I'd ever seen - he watched the entire show from start to finish, completely fascinated. When the squids would appear out of the depths he would literally drop his jaw open a bit as if to say, "oooooh! look at that!" Anytime the show aired I'd put it on and he'd faithfully watch it. To this day I don't know what he found so interesting (from a cat's perspective). It's not like he knew what a squid was - they aren't actually the natural prey of kittehs.
