That means that when our world was young, the universe was quite a bit smaller than it is today. The nearest galaxies to our own are around 10 kpc (kilo-parsecs) in size, lie at a distance of around 1 Mpc from us. 1 answer; Astrophysics; WebbThere are four distinct types of galaxies in the universe, elliptical, spiral, barred spiral, and irregular. Although these are the four main types, there are various types of galaxies and the way in which they are classified is by their shape. A galaxy is a cluster of stars, gas, and dust that are kept together by the force of gravity.

Webb30 sep. 2014 · Astronomers use five main methods to measure the SFR. Each measures the flux at different wavelengths to back out the recent star formation. The most massive stars are brightest in the UV. Studying either the far or near UV flux (FUV and NUV) constrains the recent formation of massive stars which provides the majority of the SFR.
