Furthermore, galaxies are organized into large clusters and other structures, which could have important implications for the overall structure, formation and fate of the universe. Active Galaxies Some galaxies,
Falco plotted the positions of galaxies and galactic clusters in the universe, it became clear that galactic clusters and superclusters are not randomly distributed. They're actually clumped together in walls (long filaments) interspersed with voids, which gives the universe a cobweb-like structure....

As more data piled up, 19th-century astronomers started to see that the nebulae were a mixed bag. Some were gaseous, star-forming regions, such as theOrion nebula, or M42– the 42nd object in Messier’s catalog – while others were star clusters such as thePleiades, or M45. ...
Based on the deepest images obtained so far, it’s one of about 2 trillion galaxies in the observable universe. Groups of them are bound into clusters of galaxies, and these into superclusters; the superclusters are arranged in immense sheets stretching across the universe, interspersed with ...
“Because present-day galaxy clusters have formed from matter that has collapsed over billions of years under its own gravity, the number of clusters observed at the present time is very sensitive to cosmological conditions and, in particular, the total amount of matter,” UC Riverside said in...
Another way of measuring the age of the universe is to estimate the age of stars in globular clusters in our own galaxy — the Milky Way. Globular clusters include up to a million stars, all of which appear to have formed at the same time in the early universe. Artic...
What is the cause of the intense luminosity of active Galaxies, such as Quasars or Seyfert? Suppose that there are 1.9 x 10^{25} stars in the universe. How many moles of stars would this be? What two factors determine how bright a star appears to be in the sky?
