About the Hulse–Taylor pulsar
The Hulse–Taylor pulsar is about 17,110 light-years from the Sun, so the light we see from it left about 17,110 years ago.
It is 20,684 light-years from the centre of the Milky Way.
The map lists it as a pulsar and shows it among the stars around the Sun, drawn on the plane of the Milky Way.
Its shrinking orbit gave the first evidence for gravitational waves (Nobel Prize 1993).
