Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array in the Atacama Desert, Chile, is the most complex observatory ever built.
Very Long Baseline Array
The Very Long Baseline Array (VLBA) is ten radio telescopes stationed across 5,351 miles. It’s the world’s sharpest, dedicated telescope array.

How to Weigh a PulsarPulses from a neutron star (rear) are slowed as they pass near the foreground white dwarf star. The effect, known as the Shapiro Delay, is the extra time delay light experiences by traveling past a massive object due to general relativistic time dilation. Spinning 317 times per second, this pulsar (PSR J1614-2230) and its companion white dwarf star complete an orbit in just under nine days. The pair, some 3,000 light-years distant, are in an orbit seen almost exactly edge-on from Earth, which gives astronomers the information they need to make a mass measurement.
