Say that again?
While I was doing research today, I read the most amazing sentence EVER. This baby was the first sentence of an introduction to a physics paper published in The Astronomical Journal. Ten bucks goes to whomever can explain this (in English!) in under 65 words.
Analysis ofgravitational microlensing observations ofthe quasar Q0957+561 hasoffered strong evidence forthe existence of anintrinsic structure within thisquasar that can onlybe explained by anonstandard luminous quasar modelconsisting of a thinaccretion disk whose interioris essentially empty ofmatter out to aluminous inner edge thatresides at about 70gravitational radii from thecentral compact object andthat is also surroundedby an order ofmagnitude larger outer ring-shapedElvis structure where thebroad blueshifted emission linesare formed.
I am a freelance science journalist based in New York City -- in other words, I live in the most expensive city in the world without a steady income. I have written for publications including Seed, The Scientist, the Boston Globe, Wired and Scientific American. Check out my website at http://www.melindawenner.com.
