What is a Quasar

  Perhaps one of the most perplexing mysteries in current astrophysics is the science behind Quasars. Quasars, or “quasi-stellar radio sources” are the brightest and most distant star-like objects in the known universe. In fact, they are so bright and ...

IGR J17091-3624 Black hole

 When we think of black holes, we generally think of structures like the ones that were previously mentioned—enormous beasts that devour entire star systems. However, not all black holes are interstellar destroyers; some are actually rather smallish. This brings us ...

NGC 1277 Black hole

For a long time, NGC 3842 was the most massive black hole that we knew about, but astronomers recently discovered one that’s even larger. In November of 2012, researchers discovered a black hole that is 17 billion solar masses.This means ...

Galaxy Clusters & Cannibalism

 When looking at the universe at a macroscale, astronomers have noted numerous large groupings of galaxies, (each containing billions of stars) that all have a similar center of mass. Our own galaxy, the Milky Way, is a part of one ...

Messier 78

 Messier 78 is a fine example of a reflection nebula. The ultraviolet radiation from the stars that illuminate it is not intense enough to ionise the gas to make it glow — its dust particles simply reflect the starlight that ...

NGC 4526 Galaxy

NGC 4526 is a lenticular galaxy in the Virgo constellation that is seen nearly edge-on. The morphological classification is SAB(s)0°, which indicates a lenticular structure with a weak bar across the center and pure spiral arms without a ring. It ...

How is a star born

 A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until ...
