Astronomers around the world have spent decades observing dozens of pulsars—the super-dense remains of exploded stars that emit regular pulses of radio waves as they spin at ludicrous speeds, like runaway lighthouses. Last ...

One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be gravitationally lensed ...
