Galaxies are giant structures made of dust, gas, stars and other celestial bodies spread through an immense area of space. Our own galaxy, the Milky Way, consists of more than a hundred billion stars strung across tens of thousands of light years. Galaxies are broken down into three basic s...

Related: How galaxies form: Theories, variants and growth Around 15% to 20% of galaxies with AGNs are bright in radiowaves and are classed as being "radio loud," according to the California Institute of Technology (Caltech). Quite what makes one AGN "radio loud" and another "radio quie...
The majority of bright early-type galaxies in this field are found at redshifts $z \\leq 1.3$ to share common properties with those of high-z cluster samples, as for the age and mass of the dominant stellar population -- which are found to be as old as 3-5 Gyr and as massive as...
Among early-type galaxies with almost circular isophotes, E0 and E1 galaxies are, at 99.3% significance, more luminous than face-on objects classified as S0(0) and S(0)(1). This result supports the view that rotation and "diskiness" are more important in the outer regions of faint early...
While red supergiants are thelargest stars, each with a radius between 200 and 800 times the radius of our Sun, blue supergiants are decidedly smaller. Most are less than 25 solar radii. However, they have been found, in many cases, to be some of themost massivein the universe. (It'...
