Hubble Discovers Quadruple Lensed Ancient Supernova
astroengine writes Astronomer Patrick Kelly, with the University of California Berkeley, and colleagues report this week about four different routes light from an ancient supernova took to reach the Hubble telescope after being deflected around an intervening elliptical galaxy. The phenomenon is known as an Einstein cross. "Basically, we get to see the supernova four times and measure the time delays between its arrival in the different images, hopefully learning something about the supernova and the kind of star it exploded from, as well as about the gravitational lenses," Kelly said in a statement. The supernova will appear again in the next 10 years, as its light takes different paths around and through the gravitational lens.
this is a test
....you insensitive clod!!!
If you think this supernova is cool, check out my daughters Video on Security.

Remember reruns?
Hey, shameless post: My daughter is in a contest based on views of her YouTube video. Please watch. https://www.youtube.com/watch?...
An article that is 70% about a basic theory that is, as they stated, over 100 years old and has had more than its fair share of proof of concept with no real insight into the new incident. It feels like being in high school again where they pound the same basic information into your brain over and over and over again.
Is this something that is going away and will come back in 10 years? why? or is it something that is expected to last for 10 years?
Only at the end does the article mention that light from the point source shows up at 4 different TIMES. Some very interesting measurements can be made.
