How do astronomer study the center of milky way galaxy?

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.


Do the Egyptian pyramids map out the milky way?

No, they do not. There are three main pyramids in Giza, out of Cairo. Egypt has other pyramids, but they do not in any way resemble a map of the barred spiral galaxy that is our beloved Milky Way. The Milky Way contains roughly 400 billion stars.

How many constellations are in your galexi?

Constellations are strictly human inventions. Each one is a pattern that the brains of people see in the brightest stars. All of those bright stars are relatively nearby neighbors in our part of the Milky Way galaxy. Astronomers now divide the map of the sky into 88 areas, each of those named for the constellation enclosed in it.


What is an artificial construct that astronomers use to map the heavens?

Astronomers use coordinate systems like equatorial and ecliptic coordinates to map the heavens. These systems help astronomers locate and study celestial objects by providing a framework for referencing positions in the sky.

Who discovered milky way?

It wasn't until telescopes that people realized that the band of light reaching across the sky, called the Milky Way since ancient times, was actually made of an immense number of stars. Astronomers still did not really understand what they were seeing until the 20th century, however.Until the 1920s, astronomers thought that what we now know to be our Milky Way Galaxy to be the entire universe, and that our whole universe was a few thousand light years across. Other "spiral nebulae" had been observed, but they were thought to be new star systems forming nearby. After Hubble (the astronomer, not the telescope named for him) observed Cepheid variable stars in the Great Nebula in Andromeda, he realized that the Andromeda "Nebula" was immensley distant, and ennormous in size, and, by extension, the other "spiral nebulae" were also huge and incomprehensibly distant. He called them "island universes", and realized that we were also in one, and that the 'Milky Way' band of stars across the sky was our galaxy's disk, seen from inside. So, even though people have been calling the band of light across the sky the Milky Way for thousands of years, it wasn't until the 1920's that we understood what it was--our galaxy!We can see only a small part of our galaxy in visible light. Since the 1960s, radio astronomers have mapped out the structure of the entire galaxy, and shown it to be a large spiral galaxy of about 100 billion stars; we are in one of the spiral arms about 8 kiloparsecs (25,000 light years) from the center of our galaxy, more or less halfway from the center to the edge.I think Gallileo came across the milky way in the 1600's. The cloudy band we now call the Milky Way has been known since ancient times (it's referenced in various cultural mythologies, for example). However, it was only in the past few centuries that it was properly identified as a galaxy, specifically our own.== == The Milky Way's true age hasn't been discovered. The only knowledge we have is of a meteorite which dates 4.7 billion years ago. And yes, Galileo discovered the odd colors of the Milky Way in the 1600's. If we could escape our galaxy, scientists believe it would look like M-31(The Great Galaxy of Andromeda)I would hesitate to talk about a "discovery" of something that is in plain sight - that people have been seeing for ... well, for as long as there have been people. Like the Sun, or the Moon, or trees, or animals - or the Milky Way.
