Has the quantity of stellar mass of the Milky Way changed much since its formation? -Space

Description : Has the quantity of stellar mass of the Milky Way changed much since its formation? -Space

Last Answer : In March 2019, astronomers reported that the mass of the Milky Way galaxy is 1.5 trillion solar masses within a radius of about 129,000 light-years, over twice as much as was determined in earlier studies, and suggesting that about 90% of the mass of the galaxy is dark matter.

What are the typical values of gas fraction (gas to stellar mass) in a spiral galaxy as a function of Hubble type? -Space

Description : What are the typical values of gas fraction (gas to stellar mass) in a spiral galaxy as a function of Hubble type? -Space

Last Answer : We show that the gas mass fraction of spiral galaxies is strongly correlated with luminosity and surface brightness. It is not correlated with linear size. Gas fraction varies with luminosity and ... the onset of significant star formation can be delayed for arbitrary periods in tenuous gas disks.

Distances of stars are measured in – (1) Galactic unit (2) Stellar mile (3) Cosmic kilometre (4) Light year

Description : Distances of stars are measured in – (1) Galactic unit (2) Stellar mile (3) Cosmic kilometre (4) Light year

Last Answer : (4) Light year Explanation: Light year is a unit of length used informally to express astronomical distances. It is most often used when expressing distances to stars and other distances on a galactic scale. It is equal to just under 10 trillion kilometres.
