Never thought I'd see the words Star and Fossil in the same sentence.

Mira has been found to have a long tail that glows only in the ultraviolet. There’s talk of studying along the length of the tail to explore the star’s past.

I think that’s ten kinds of cool.

Google news has a list of additional articles, too.

The tail includes carbon and oxygen, so the articles talk about it seeding future planets.

Are there extra-solar planets?

It sounds to me like there’s a good chance that some of the matter in that 13-light-year-long trail behind Mira will ultimately coalesce into solid matter, and in planet-sized chunks, to boot.

So… this suggests to me that it wouldn’t be all that weird to imagine that there are a fair number of extra-solar planet-sized masses floating about out there.
