SCIENTISTS MEASURING MILKY WAY WITH RADIO WAVES

Scientists have used radio waves to measure the Milky Way galaxy. A collection of radio telescopes that spans thousands of miles and is remotely operated from central New Mexico has measured a span of 66,000 light-years (one light-year is equal to 6 trillion miles) from Earth across the Milky Way’s center to a star-forming area near the edge of the other side of the galaxy. Astronomers say they hope to measure additional points around the galaxy to produce a map — the first of its kind — over the next decade.
* Radio waves – is there nothing they can’t do?
* The Milky Way is 66,000 light years across. 66,000 delicious, chocolate-malt nougat-y light years.
