"Our results show that the Milky Way Galaxy is not flat. It is warped and twisted far away from the galactic centre. Warping may have happened through past interactions with satellite galaxies, intergalactic gas or dark matter (invisible material present in galaxies about which little in known)."Aug 1, 2019
Why is the Milky Way flat?
It's actually several thousand light years thick… approximately 10,000 light years in the core, and about 3,000 out towards the galactic rim. However, the interplay between gravity and centrifugal force is what causes spiral galaxies like ours to “flatten out”.
Why is the Milky Way not flat?
From above, the Milky Way can be seen as a spiral-shaped galaxy, but this spiral disk doesn't sit flat on the galactic plane. The cepheid stars cluster along an S-shaped curve, showing that the Milky Way's disk is more warped than previously thought.
Is the Milky Way bent?
The galaxy's disk of stars and gas is mostly thin and flat toward the middle. But at roughly the sun's distance from the core, the galaxy begins to bend, flexing upward in one direction and flopping down in the other.
Which way is the galaxy moving?
Astronomers believe the Milky Way is moving at approximately 630 km/s (1,400,000 mph) with respect to this local co-moving frame of reference. The Milky Way is moving in the general direction of the Great Attractor and other galaxy clusters, including the Shapley supercluster, behind it.
Is the Milky Way spinning?
The Milky Way rotates at a whopping 130 miles (210 kilometers) per second, but a new study has found that dark matter has slowed the rotation of its bar by at least 24% since its formation nearly 14 billion years ago.
Are galaxies flat?
Galaxies are flat because of their rotation. All of the stars, planets and other objects in a galaxy are rotating around the core of the said galaxy, and the conservation of angular momentum allows these objects to spread outward, but not any other direction, which is why they are flat.
Is the Milky Way a circle?
The Milky Way is actually a galaxy — a large system of stars, gas (mostly hydrogen), dust and dark matter that orbits a common center and is bound together by gravity. Our galaxy is spiral-shaped. Contrary to popular belief, our solar system is not at the center of the galaxy.
Does the Milky Way orbit a black hole?
In the case of Sagittarius A*, astronomers observed the orbits of S2 and its stellar companions and found that they must be circling around a massive object that could only be a black hole. By 1974, astronomers officially dubbed Sagittarius A* the Milky Way's supermassive black hole.
Can the Earth survive Andromeda collision?
Excluding planetary engineering, by the time the two galaxies collide, the surface of the Earth will have already become far too hot for liquid water to exist, ending all terrestrial life; that is currently estimated to occur in about 3.75 billion years due to gradually increasing luminosity of the Sun (it will have …
