Astronomers Use Distributed Supercomputer to Reconstruct Ancient Dwarf Galaxy astronomy space science
, astronomers have calculated the original mass and size of a dwarf galaxy that was shredded in a collision with our own Milky Way Galaxy several billions of years ago.A few dozen dwarf galaxies are known to orbit around our Milky Way Galaxy.
As such, dwarf galaxies act as gravitational probes for determining the distribution of gravitating mass in the Milky Way. “Now we have a measurement from data, and it’s the first big step toward using the information to find dark matter in the Milky Way.” “And that takes a lot of computer power, which we get with the help of volunteers all over the world who are part of MilkyWay@home.”
The remainder is assumed to be dark matter that exerts gravitational force, but that we cannot see because it does not absorb or give off light.
