Why is the center of Milky Way so bright?

The black hole at the center of our galaxy is pulling in entire solar systems. A mixture of gasses and dust particles are being sucked towards the black hole under large amounts of pressure and heat due to friction. This makes the matter around the hole incredibly bright.

Earth and the moon can be seen as two distinct bright evening'stars' by a human observer standing on Mars.

The annual salaries of astronauts are determined using a government pay scale, and start out under two grades: GS-12 and GS-13. According to the US government's 2020 pay scales and a NASA job listing, a civilian astronaut in 2020 can earn between $US 66,167 and $US161,141 per year.

The Galactic center appears to have: A stellar density a million times higher than near Earth. Apparently, there is a supermassive black hole in the center of our Galaxy. It is called Sagittarius A and has a mass of 4 million solar masses. Consequently, what is in the center of the milky way? At its center, surrounded by 200-400 billion stars and undetectable to the human eye and by direct measurements, lies a supermassive black hole called Sagittarius A*, or Sgr A* for short. The Milky Way has the shape of a spiral and rotates around its center, with long curling arms surrounding a slightly bulging disk.

Why is Earth the center of the universe?

The Earth is the center of the universe and is stationary. The planets, sun and stars revolve around Earth. All motions in the sky should follow circular paths as objects are attached to spherical shells. Objects obeyed the rules of 'natural motion' meaning they orbited Earth at the same speed. You can also ask what is the center of the earth called? core Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).

The universe, in fact, has no center. Ever since the Big Bang 13.7 billion years ago, the universe has been expanding. But despite its name, the Big Bang wasn't an explosion that burst outward from a central point of detonation. The universe started out extremely compact and tiny. Then, how old is the earth? Today, we know from radiometric dating that Earth is about 4.5 billion years old. Had naturalists in the 1700s and 1800s known Earth's true age, early ideas about evolution might have been taken more seriously.
