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.

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.
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.

The super-massive black hole at the center of MY galaxy is about 25,000 light years from me. Not sure how far away you are from the center of YOUR galaxy, however.
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.
Probably the same as the center of YOUR galaxy.

A spiral galaxy
Because of the clouds of gas and dust that exist in the Milky Way, we are unable to see stars near the core of the galaxy. So, if there is one there, it does not have a name. But it is entirely possible that there is not star at the center of our galaxy. Recent radio telescope observations indicate that many galaxies contain hyper-massive black holes at their centers, and our own Milky Way might be among them.
Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.
