What was found at the center of our galaxy?

A supermassive black hole is located at the center of the Galaxy. Measurements of the velocities of stars located within a few light-days of the center show that the mass inside their orbits around the center is about 4.6 million MSun.

What is the bright light at the center of a galaxy?

The galaxy’s center is the bright white spot in the middle of the photo — that’s where hot massive stars crowd together. Somewhere in that center lies a supermassive black hole.

How long is galactic year?

220, 230 million years
Compared with an Earth year, a galactic year represents time on a grand scale — but it’s not a consistent measurement across the galaxy. What we Earthlings call a galactic year is specific to Earth’s place in the Milky Way’s spiral. “We would say that a galactic year is 220, 230 million years.

Where is the galactic bulge?

In the center of the galaxy is the bar-shaped galactic bulge which harbors a supermassive black hole with a mass equal to that of about 3 million suns. Surrounding the central bulge is a relatively thin disk of stars about two thousand light years thick and roughly 100,000 light years across.

Is our galaxy orbiting something?

No, the Milky Way is not orbiting anything else, such as the center of the universe, so it has no orbital period. The Milky Way is spinning like a frisbee as it heads out in a straight line from the Big Bang, which happened 14 billion years ago.

What are facts about the Galaxy?

Galaxy Facts. A galaxy is a massive, gravitationally bound system that consists of stars, stellar objects (such as brown dwarfs and neutron stars), nebulae, an interstellar medium of gas and dust, black holes, and an unknown component of dark matter. Examples of galaxies range from dwarfs with as few as ten million stars to giants…

Where is Earth in the Milky Way?

The Solar System (and Earth) is located about 25,000 light-years to the galactic center and 25,000 light-years away from the rim. So basically, if you were to think of the Milky Way as a big record, we would be the spot that’s roughly halfway between the center and the edge.

How old is Sagittarius A*?

The Age of Sagittarius was approximately 22,500 – 20,000 BCE. The coming Age of Sagittarius will be in 4,000 years or so. We started this Cycle of Healing by taking a look forward into the next Age of Capricorn.

What is the center of a black hole?

At the center of a black hole is what physicists call the “singularity,” or a point where extremely large amounts of matter are crushed into an infinitely small amount of space.
