Supernova clusters are regions within galaxies where multiple supernova explosions have occurred relatively close to each other in space and time. These clusters provide valuable insights into the life cycle of massive stars and the impact of supernova explosions on their surrounding environment. A well-known example is the Cygnus Loop in the constellation Cygnus, which is a supernova remnant created by a cluster of supernova explosions.
Global clusters, or globular clusters, are older, densely packed groups of stars that formed early in the universe's history. They have fewer heavy elements, or metals, because they originated before significant stellar evolution and supernova events that create and distribute these elements. In contrast, open clusters are younger and formed in regions that have already experienced multiple generations of star formation, leading to a higher abundance of heavy elements due to the recycling of materials from previous stars.
the 3 clusters of PECs are Achievement Clusters , Planning Clusters and Power Clusters
Probably not. Dark matter is not believed to concentrate well in or around masses the size of stars. But it does concentrate well around galaxies and clusters of galaxies. Most of the mass of a galaxy like ours is believed to be in a sphere of dark matter in the galaxy's spherical halo.
The Vela Supernova is the remnant of a supernova explosion that occurred in the Vela constellation about 11,000 to 12,300 years ago. It is located about 800 light-years away from Earth and is one of the closest known supernova remnants to us.
"after a supernova" is the adverb phrase in the sentence.

Yes, most supernova explosions in star clusters occur within the first 100 million years of the cluster's formation. This is primarily because massive stars, which end their lives as supernovae, have shorter lifespans and evolve rapidly. Consequently, the high rate of massive star formation in young clusters leads to a significant number of supernovae happening in this initial period. After this time, the rate of supernova occurrences decreases as the massive stars have already exploded.

Darkness allows us to better see the stars and nebula, supernova remnants, interstellar clouds of hydrogen, star clusters and distant galaxies. Dark skies. Light pollution robs our children of their birthright--the enjoyment of the heavens.
