A black hole is a remnant of a super massive star that lived out its life and died. We expect those black holes to be pretty much rare but everywhere if you can picture that. Hubble telescope gets launched and every galaxy we look into and have the quality of data to know, they've all got a supermassive black hole. The James Webb Space Telescope is exquisitely tuned to see the birth of galaxies. And from those data, we might be able to see material collecting in the middle to form the supermassive black holes that dot the center of every galaxy.
Can there be life on planets without magnetic fields? Neil deGrasse Tyson and comedian Chuck Nice discuss exoplanets, extraterrestrials, and answer extraordinary questions from our fans with astrobiologist, David Grinspoon.
