Question

How does the milky-way differ from other galaxies?

Answer 1

Hint :A galaxy may be a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way , also features a supermassive region within the middle. Once you search at stars within the night sky, you're seeing other stars within the Milky Way .

Complete Step By Step Answer:
Our galaxy, the Milky Way , is typical: it's many billions of stars, enough gas and mud to form billions more stars, and a minimum of ten times the maximum amount of substance as all the celebs and gas put together. And it’s all held together by gravity. Like quite two-thirds of the known galaxies, the Milky Way features a spiral shape.
 At the middle of the spiral, tons of energy and, occasionally, vivid flares are being generated. Supported the immense gravity that might be required to elucidate the movement of the celebs and therefore the energy expelled the astronomers conclude that the middle of the Milky Way may be a supermassive region. Other galaxies have elliptical shapes, and a couple of have unusual shapes like toothpicks or rings.

Note :
The Milky Way contains over 200 billion stars, and enough dust and gas to form billions more. The system lies about 30,000 light-years from the galactic center, and about 20 light-years above the plane of the galaxy. Quite half the celebs found within the Milky Way are older than the 4.5-billion-year-old sun.
