hole   This composite image shows a supernova within the galaxy
M100 that may contain the youngest known black hole in our
cosmic neighborhood. In this image, Chandra’s X-rays are colored
gold, while optical data from ESO’s Very Large Telescope are
shown in red, green, and blue, and infrared data from Spitzer
are red. The location of the supernova, known as SN 1979C, is
labeled. (Photo from NASA)  NASA astronomers have discovered
what’s thought to be the youngest black hole known to exist near
the Earth, meaning researchers will be able to watch it develop
from its earliest stages.  When it comes to black holes, 30
years old is young — very young. And 50 million light years from
Earth is considered very close.  From NASA:  The black hole is a
remnant of SN 1979C, a supernova in the galaxy M100
approximately 50 million light years from Earth. Data from
