It's not a "remnant" of a black hole; there is a black hole at the center of the Milky Way, period. And as far as I know it wasn't discovered by any single telescope; rather, it has been observed over several years, with different instruments, and scientists have come to the conclusion (based on such observations) that the only explanation for what they observed is a black hole.
Shapley discovered that the Milky Way is not at the center of the universe, but rather on its outer edge. Oort determined that the galaxy is rotating and that the Sun is located about halfway between the center and the edge.
He Discovered that Earth was not the center of the solar system , Jupiter Has four moons and Venus has light and dark phases, like a moon! He also discovered the rings of Saturn. All this using just one telescope? Galileo didn't invent the telescope, but he was the first person we know of to point a telescope into the skies - and discovered that Jupiter wasn't just a bright light in the sky, but was an enormous planet with moons of its own. The four largest are called the "Galilean" moons; Ganymede, Europa, Callisto and Io.
neutron star has been observed at the center of a supernova remnant, known as the Crab Nebula. This neutron star, also called a pulsar, spins rapidly, emitting beams of radiation that are observed as pulses by astronomers.
No. The super massive black hole at the center of the galaxy has about 4 million times the mass of the sun while the galaxy as a whole has at leas 1 trillion solar masses. In other words the black hole at the center of the galaxy accounts for about one twenty-fifth of one percent of the galaxy's mass.
Not "the" quasar, but "a" quasar - there are many. A quasar is associated with a supermassive black hole, and those are generally at the center of galaxies.
They use powerful devices such as the Hubble Space Telescope, and infrared and ultraviolet waves. Astronomers also use the direction of the path of light, gamma rays, and beta particles to study the center of our spiral-shaped Milky Way Galaxy.
Harlow Shapley determined the center of the galaxy by studying the distribution and motion of globular clusters. By observing the positions and velocities of these clusters, he discovered that they were not evenly distributed in the sky but rather congregated towards a point in the constellation Sagittarius, indicating the center of the galaxy.
Probably the same as the center of YOUR galaxy.

He discovered that Earth was not the center of the solar system, Jupiter has its own moons, and Venus has phases like a moon! He also discovered the rings of Saturn. All this just using one telescope.

At the center of every galaxy is a supermassive black hole.
