Astronomers Dissect a Supermassive Black Hole

Matt_dk sends along a piece from the European Southern Observatory, which reports on observations of the so-called "Einstein Cross," a fortuitous conjunction of a nearby galaxy and a distant black hole. A team of researchers from Europe and the US combined the effects of macrolensing (from the intervening galaxy) and microlensing (from stars in that galaxy), captured by an earth-bound telescope. "Combining a double natural 'magnifying glass' with the power of ESO's Very Large Telescope, astronomers have scrutinized the inner parts of the disc around a supermassive black hole 10 billion light-years away. They were able to study the disc with a level of detail a thousand times better than that of the best telescopes in the world, providing the first observational confirmation of the prevalent theoretical models of such discs."

Quote FTA:

"The use of the macro- and microlensing, coupled with the giant eye of the VLT, enabled astronomers to probe regions on scales as small as a millionth of an arcsecond. This corresponds to the size of a one euro coin seen at a distance of five million kilometres, i.e., about 13 times the distance to the Moon!"

A truly fortuitous occurence. How long before our technology can catch up to that level?

On the otherside of the visible universe

It has not been that long since people first discovered such quasars, and at that time they seemed destined to remain a mega-distant mystery. In the mean time astronomers have accumulated a large body of results on gravitational lensing, which itself is a prediction of Einstein's not-too-old general theory of relativity. Now this technique has been used to form a galatic-cluster-scale configuration that acts as a telescope which can bring us images of this extreme level of detail from across the visible universe. We live in a very exciting period for the science of astronomy.

I want Einstein's cross on a silver chain

... seriously. This would be such a great accessory for the scientifically-minded. It's a nice, distinctive-looking piece of science. Wear it as an atheist as a statement about religion; wear it next to your christian cross as a non-atheist as a statement about rational spirituality. Whatever - I just think someone could make a nice piece of thoughtful jewelery out of this.
