Why is it difficult to get a good picture of what our Milky Way galaxy looks like?
Why is it difficult to get a good picture of what our Milky Way galaxy looks like? -We’re in the middle of one of its arms, so we have no perspective. -It is very large and the edges are far away and faint. -Dust blocks our view when we look toward the center or in the plane.
Are all visible stars Suns?
Every star you see in the night sky is bigger and brighter than our sun. Of the 5,000 or so stars brighter than magnitude 6, only a handful of very faint stars are approximately the same size and brightness of our sun and the rest are all bigger and brighter.
Is the Milky Way circular?
The disk of our galaxy is flattened by rotation (just as the planet Saturn is flattened, and protostellar disks are flattened.) Individual stars in the disk are on nearly circular orbits in the plane of the disk, all revolving in the same direction around the center of our galaxy.
Why is the Milky Way not a sphere?
This is because the force of the spin actually cause the entire structure to flatten a bit. This causes there to be more mass along the “waist line” of an object. The center of Galaxies like the milky way are inhabited by supermassive black holes which spin amazingly fast.
Why do galaxies look flat?
Solar Systems/Galaxies are flat because of the rotation of the central mass (star in case of solar system, while a supermassive black hole in case of a galaxy) around its own axis. Because the sun rotates in a plane, the accretion disc was formed in the same plane, and the resultant planets formed in the same plane.
Is the Milky Way shaped like a sphere?
Our galaxy, the Milky Way, is disk-shaped with spiral arms. It has an elliptical bulge in the centre and a spherical halo that is denser closer to the Galaxy centre. It is about 100,000 light years across and our solar system is about two thirds of the way out from the centre.
What is the middle of a galaxy called?
Galactic Center
How many planets are in the space?
eight planets
