Milky Way Mass refers to the total mass of the Milky Way galaxy, including its dark halo, which is approximately 10^12 times the mass of the Sun. This mass is estimated through various measurements, such as the orbits of satellites and the distribution of standard candles, with some uncertai...
Output of the ERIS disk galaxy formation simulation aimed at following the formation history of a Milky-Way-like galaxy ab initio. The figure shows a projection resembling the 2MASS map of the Galaxy, and shows that simulations have now reached a point where, with very quiescent merging histori...
Aside from these lines of evidence, astronomers are also using their tools in ingenious ways to map the structure of the Milky Way. Just this year, scientists used two radio astronomy projects from different parts of the globe to measure theparallaxes– differences in the ...
From the folks that brought you the addictive citizen science projects Galaxy Zoo and Moon Zoo (among others), comes yet another way to explore our Universe and help out scientists at the same time.The Milky Way Projectinvites members of the public to look at images from infrared surveys of ...
Figure 1. The edge-on view of the log-scaled density projection map of the stellar, dark matter and gas components in the main galaxy system within its virial radius in the “C−4” simulation at redshift 𝑧=0z=0. Figure 2. The face-on and edge-on views of the density projecti...
