Near-Perfect Einstein Ring Discovered
Fraser Cain writes "Universe Today is reporting on the discovery of a nearly perfect Einstein Ring; a gravitational lens of a nearby galaxy working as a natural telescope to focus the light from a more distant galaxy. Gravitational lenses have been seen many times before, but never so complete, with a close lensing galaxy and a distant magnified galaxy."
Well, this is a nice discovery to celebrate the 100 years of the Einstein's miraculous year and 50 years since the guy passed away.
If we can see that universe better, the opposite is true, they can see us better.
That being said, I want to be the first to welcome our new voyeuristic overlords.
We're going to have more powerful ground based (and therefore maintainable) telescopes very soon. A more important science project to keep alive is the Voyagers. It has taken decades to get them where they are, and the deviation of their trajectories from the predicted trajectories is very valuable to get an idea of the dark matter present in our own solar system.
The information available from tracking them, can only be obtained again after more decades of having launched a probe, and it is therefore less easily replaceable.
Something a lot less worthwhile?
