Galaxies - senwiki
... A galaxy is an immense grouping of stars, planets and dust. The matter in a galaxy is held together by gravitational attraction (i.e. it doesn’t just fall apart and separate) Within galaxies, there are many long cycles of star formation (from dust and gas) and supernovae; more dust and gases. ...

If a galaxy is receding at 7000 km/s, its redshift distance is ~100 Mpc. This works if the Hubble velocity is high enough to washout peculiar local mo ...

Pea galaxy
A Pea galaxy, also referred to as a Pea or Green Pea, might be a type of Luminous Blue Compact Galaxy which is undergoing very high rates of star formation. Pea galaxies are so-named because of their small size and greenish appearance in the images taken by the Sloan Digital Sky Survey (SDSS).Pea Galaxies were first discovered in 2007 by the volunteer users within the forum section of the online astronomy project Galaxy Zoo (GZ).
