IC3418 is a dwarf galaxy located within the Virgo Supercluster and appears to be crossing from life to death. Scientists estimate that IC3418 essentially ran out of gas around 250-million years ago. - Credit: NASA/JPL, Caltech

IC 2574: Coddington's Nebula (June 22 2012)  Image Credit & Copyright: Stephen Leshin Grand spiral galaxies often seem to get all the glory, flaunting their young, bright, blue star clusters in beautiful, symmetric spiral arms. But small, irregular galaxies form stars too. In fact dwarf galaxy IC 2574 shows clear evidence of intense star forming activity in its telltale pinkish regions of glowing hydrogen gas. Just as in spiral galaxies, the turbulent star-forming regions in IC 2574 (...)…

One of the Largest Structures in the Universe:  Astronomers recently discovered a group of active galactic cores that stretch more than 4 billion light-years end to end. The structure is a large quasar group (LQG). And it is simply massive.     For comparison, the Milky Way is about 100,000 light-years across. Our closest neighboring galaxy (Andromeda) is some 2.5 million light-years distant, and it is more than twice the size of the Milky Way (about 260,000 light-years

How big is the universe?   This infographic, designed by Number Sleuth, visualizes the size of the universe and its contents by allowing you to scroll down from the very largest known objects to the smallest and compare their relative sizes. Each row in the graphic represents a “level” and the blue funnel represents you zooming from one level to the next, going from larger to smaller.
