Blue Ring Nebula

[Brightmoon]

Two stars collided and formed this several thousand years ago

I assume that it was not two stars which had different solar systems. I would guess that twin stars merge into each other a lot more often than say our sun with some other star out there. Please someone provide the link so I can read it. sometimes with these articles you have to have a specific kind of link to be able to show others it. if you use the normal URL it won't work.

You're welcome.

I know from past posts that you sometimes have a problem adding links. I'm happy to help where I can.

Why cant you link? On chrome u click the web address then the top of the list has a "<" looking thing but with a dot on corner and both ends of the lines. Then u click on "copy to clipboard" then u hold finger on typing medium then select paste. Dunno y they make things so overcomplicated. Your web browser does not look like chrome but seems like there should be a way. :/

Funny. Just had to reboot my phone cause it spazzed out. One day technology will stop being imperfect and annoying.

A preprint version is available on the arXiv at:

Stellar mergers are cool. The best fit is a ~0.3 M_solar star merging into a ~2 M_solar star.
