The Blue Ring Nebula is actually two cones of debris moving out from a collision between two stars.
The Blue Ring Nebula was discovered by NASA’s Galaxy Evolution Explorer mission (GALEX). The astronomers think that a star similar to our Sun pulled in its binary star partner which was much smaller. This has left it about 4 parsecs across, which is about 13 light years, or 123,000 billion kilometres.
Star collisions like this may happen often, so it’s quite likely that a lot of the single stars we see were once pairs that collided.
Areas of dust and gas are common in the Universe. They can form in many different ways, but they’re always beautiful as the slideshow below shows.
Diablo nebula. The Blue Ring Nebula looks a lot like the juggling toy called a ‘diablo’. You can make your own diablo and learn some juggling tricks for it. The good people at Circomedia will show you how in these videos.
You probably don’t already have your own diablo, but it’s quite easy and cheap to make one. You will need an adult to help you… This video will show you how.
As well as a helpful adult, here’s the equipment you’ll need to make it:
2 round plastic tubs (Must be the same size & weight)
String – Ideally light, tightly woven
4 small screws
A carving knife/Pen Knife
Finally, you could decorate your diablo to make it look like the Blue Ring Nebula!
