Scientists watch the same star supernova more than once
I have been since I was a kid and still am to this day fascinated by space, the science of it and the mystery too. I've posted a few articles related to space, here's another one that i thought was very very interesting:
Astronomers Watch a Supernova and See Reruns March 5th 2015, NY Times http://www.nytimes.com/2015/03/06/sc...runs.html?_r=0 It’s “Groundhog Day” in the cosmos. In the 1993 Bill Murray movie, a weatherman finds himself reliving the same day over and over again. Now astronomers using the Hubble Space Telescope say they have been watching the same star blow itself to smithereens in a supernova explosion over and over again, thanks to a trick of Einsteinian optics. The star exploded more than nine billion years ago on the other side of the universe, too far for even the Hubble to see without special help from the cosmos. In this case, however, light rays from the star have been bent and magnified by the gravity of an intervening cluster of galaxies so that multiple images of it appear. Four of them are arranged in a tight formation known as an Einstein Cross surrounding one of the galaxies in the cluster. Since each light ray follows a different path from the star to here, each image in the cross represents a slightly different moment in the supernova explosion. I was sort of astounded,” said Patrick Kelly of the University of California, Berkeley, who discovered the supernova images in data recorded by the space telescope in November. “I was not expecting anything like that at all.” Dr. Kelly is lead author of a report describing the supernova published on Thursday in the journal Science.

Or it could be a glitch in the matrix. Agents are coming.

Nice of the cosmos to help our scientists see it. And yet some will STILL claim there isn't, at least, "Intelligent Design" at work here.

Good observation of Supernova with General Relativity.

I was thinking about this last night as I saw a BEAUTIFUL sunset, the sky filled with high clouds reflecting the orange glow of our sun. I also thought of the other life forms, in their non-water based planet, watching their white dwarf reflect bluish hues from the chlorine-gas clouds reflecting at sunrise, and just how similar we are. Also, I can't recall ever seeing anything near as beautiful as when peaking under Mother Nature's skirts and seeing something she has made.
