Question

Has any one ever seen a black hole with a naked eye or through a telescope?

Answer 1

All you need is a 20 cm telescope in order to see a nearby, active black hole, according to researchers.

Once in several decades, some black hole binaries undergo "outbursts" in which enormous amounts of energy are emitted from substances that fall into the black hole. Black holes themselves are commonly surrounded by an accretion disk, in which gas from a companion star is slowly drawn to the hole in a spiral pattern. Activities of black holes are typically observed through X-rays, generated in the inner portions of accretion disks where temperatures reach 10 million degrees Calvin more.

Answer 2

ANSWER

a black hole is a region of space time exhibiting such strong gravitational effects that nothing not even particles and electromagnetic radiation such as light can escape from inside it. The theory of general relativity predicts that of sufficiently compact mass of can deform spacetime to form a black hole.
