We get many quasars, but they're all far away because nearby galaxies ate their gas. The nearest one is the Cygnus X-1 black hole, which is about a thousand light years away. But there could be galaxies that are quasars for some parts of the universe and not for others. And so we don't even have a galaxy that would have been one close to us.
Can we use gravitational lensing to view distant planets? Neil deGrasse Tyson and comedian Chuck Nice explore black holes, quasars, entropy, and more with astrophysicist and host of PBS Space Time, Matt O’Dowd.
