Planet wide millimeter radio telescope array now has ten times the resolution
The improved level of detail is equivalent to being able to count the stitches on a baseball from 8,000 miles away.
- VLBI (Very Long Baseline Interferometry) now links radio telescopes spread across the globe into what is, in effect, a telescope the size of our planet
- extending the array to millimeter wavelengths achieved a further boost in resolving power.
The result is an order-of-magnitude increase in the sensitivity of the world's millimeter VLBI networks.
