Partly: The formation of an open cluster begins with the collapse of part of a giant molecular cloud (a dense cloud of gas containing thousands of times the mass of the Sun) Many factors could trigger the collapse of a giant molecular cloud (or part of it) and a burst of star formation which will result in an open cluster, including shock waves from a nearby supernova and gravitational interactions.
Yes, pulsars are often found in supernova remnants. Pulsars are rapidly rotating neutron stars that emit beams of radiation, and they are formed when a massive star undergoes a supernova explosion. The remnants of the supernova provide the environment from which the pulsar originates.

There are many types of nebula and they can form within any galaxy. Generally, the normal types of nebula - planetary and supernova remnants will occur in the younger galaxies, so at a push spiral galaxies.
Quasars are related to supermassive black holes in the center of galaxies.
The youngest stars are protostars which are still forming within giant molecular clouds. The oldest stars in the universe are believed to be Population II stars, which are remnants from the early universe and can be found in globular clusters.
Fossils.
Those are called globular clusters, or star clusters.
Round clusters of coccus bacteria are called staphylococci. Staphylococci are a type of bacteria that are typically found in clusters and can cause infections in humans.
near giant elliptical galaxies.

A supernova can reach temperatures of around 10 billion degrees Celsius during the explosion. This extreme heat is produced by the rapid fusion of elements and the release of vast amounts of energy. Such temperatures are far beyond those found in typical stars, making supernovae some of the hottest phenomena in the universe. After the explosion, the remnants can still remain incredibly hot, often exceeding millions of degrees.
