NASA has reported it is currently using Chandra to study a ‘halo,’
or giant gas cloud in NGC 6240. This phenomenon is occurring due to the
collision of two galaxies. NASA is reporting that each of these galaxies, are
not only spiral galaxies, but are also about the size of our own. Both galaxies
have a black hole in the center. This collision could cause one enormous black
hole to form.
A baby boom makes this collision all the more interesting.
This occurred because the collision has caused the gas in each galaxy to become
stirred up. New stars have been created for at least 200 million years,
producing some supernovas. This is interesting because they released elements
into the hot gas, which is mixing with the cooler gas.
