The following link:
Relative size of our world: http://www.rense.com/general72/size.htm Got me to thinking of big burning balls of gas in the sky. Over the ages one must have been drawn into collision with another. Are any available to the kind of telescopes we might have at home? TBerk |

As for how would you know- well I would think the collision of two stellar masses would be a spectacular and demonstrative event. TBerk |

As for how would you know- well I would think the collision of two stellar masses would be a spectacular and demonstrative event. It might be -- though a really spectacular interaction would end up destroying both stars, and that clearly doesn't always happen (if it *ever* does) or we'd never find any blue stragglers today. Stellar collisions are very rare events. Even in the dense globular clusters, it's expected that there might be a couple hundred collisions over the whole ~10 billion year lifetime of each cluster. So maybe a few tens of thousands over the lifetime of our galaxy. And they'd be brief events, so unless we were very lucky we'd not see one within our lifetimes. And, they'd almost certainly happen in the densest part of the core of the star cluster, so they'd be hard to see clearly if we did catch one. |

Over the ages one must have been drawn into collision with another. Stars are indeed very large compared to the Earth. But the space between them is ever so much larger still. For this reason stars do not generally run into one another on any timescale, much less on a timescale short enough that we can observe it. The primary exception is the coalescence of stars in a very close binary system, but this too is something which occurs too rarely to be observed. -- Greg Crinklaw Astronomical Software Developer Cloudcroft, New Mexico, USA (33N, 106W, 2700m) SkyTools: http://www.skyhound.com/cs.html Observing: http://www.skyhound.com/sh/skyhound.html Comets: http://comets.skyhound.com To reply take out your eye |
