Want to see a star within another Galaxy??
. ...trust me, it is not a "normal" occurrence!
This is amateur astronomer, Mark Striebeck's photo of M82; a galaxy over 12 MILLION light years away. All the individual stars in this image, are stars within our own galaxy. Whereas stars in other Galaxies (such as M82) are far to distant to make out as individual formations...
. ...EXCEPT, the star those two lines are pointing to!!
This now visible feature, is a supernova which erupted a few weeks ago within this galaxy. The supernova is so bright, that we can now see it as an individual star - shining as bright as the entire combined ("M82's") galaxy of neighboring stars.
Actually, this supernova erupted 12 million years ago!! - the light from it's eruption only arrived here last week! ...pretty cool, huh?
(Excuse me, while I digress: Please ignore, if you're outside the "Bible Belt"!
This rare experience, which "occurred 12 million years ago", unless; you're of a persuasion, for some odd reason, (cough, cough - attempted literal interpretation of the Book of Genesis,) which denies light travel's at a "constant speed". In which case you are free to believe the universe, earth, and all our infinite surroundings, are however old you wish.
Although, you might avoid using our countless ubiquitous technologies, based on the same known principals and physical facts; such as the microwave oven, your satellite TV, any GPS based navigation - including but not limited to a commercial aircraft, the internet, your cell phone, etc..
...Sorry... I have far to many acquaintances guilty of "The Backfire Effect" (a.k.a. "confirmatory Bias": http://en.wikipedia.org/wiki/Confirmation_bias
) ...where related to their denial of science. And it is simply a shame to miss out on this true renaissance in Astronomy and Physics, which our generation is exceptionally privy to. (Not to mention all the subsequent understanding of the technological and scientific world you are surrounded and impacted by.)
I didn't mean to "digress" so drastically! It is just a very frustrating habit; when you post something so exceptional, and you immediately realize their is a shocking amount of your audience, which will consider the entire revelation "poppycock". It's a bizarre function of a social influence I still find hard to get my mind around; both my own "digression", and so many of my peer's denial.)
