Different types of electromagnetic waves provide different kinds of information. Specifically, black holes will emit large amounts of x-rays.
Supernova explosions are believed to generally result in a black hole, as the core of the star is collapsed into an unimaginably dense point mass. One can't really say that a black hole is any kind of star. Less powerful nova explosions probably result in pulsars or neutron stars.
X-ray telescopes
They will end up as neutron stars or even black holes. Usually they will first explode as a supernova (of type1a).
after a supernova
Either a black hole, or a neutron star. That depends on how much mass is left after the supernova explosion.

Copper can only form in supernova explosions, when a dead star collapses to become either a neutron star or a black hole.

You can learn all about telescopes, stargazing, comets, constellations, galaxies and black holes. Find out who invented the telescope, famous astronomers and space exploration.

specifically, "astronomers" that study black holes are called cosmologists.
No.
Black holes came from old big stars that went supernova as it dies. Supernova causes the star to collapse into a black hole

Black series telescopes are good telescopes to buy for seeing different planets. They allow a clear view for stargazing.
A black hole is often the RESULT of a supernova explosion. When a massive star dies, the star explodes. The core of the star is crushed, while the outer layers of the star are blown away into space. This explosion is a nova or supernova. The early astronomers, seeing a burst of light where no star had ever been seen before, called them "nova stellarum", or "new star". When the core of the star is crushed by the explosion, the result is a neutron star or a black hole, depending on how densely the core is collapsed.
