Ref. https://www.sciencedaily.com/releases/2020/02/200227114459.htm  Date: February 27, 2020 Source: International Centre for Radio Astronomy Research Summary: Scientists studying a distant galaxy cluster have discovered the biggest explosion seen in the Universe since the Big Bang. The blast came from a supermassive black hole at the centre of a galaxy hundreds of millions of light-years away. It released five times more energy than the previous record holder. This extremely powerful eruption occurred in the Ophiuchus galaxy cluster, which is located about 390 million light-years from Earth. Galaxy clusters are the largest structures in the Universe held together by gravity, containing thousands of individual galaxies, dark matter, and hot gas.

An astrologer is someone who makes logs about the stars. You know, like... Captains log, stardate 2403.6... We are currently in orbit of Uranus, in search of the Klingon warships that have been plaguing the outer solar system... An astrophysician, on the other hand, is a doctor who specializes in healing asteroids. They are very important in the game "Asteroids", because after the player blasts all the asteroids to smithereens,  someone  has to put them back together for the next game! A cosmetologist is just a Russian word for a person who's so tall that his head is figuratively in space.

What is Astrophysics ! details below from wikipedia ! From Wikipedia, the free encyclopedia Jump to navigation Jump to search This article is about the use of physics and chemistry to determine the nature of astronomical objects. For the use of physics to determine their positions and motions, see  Celestial mechanics . For the physical study of the largest-scale structures of the universe, see  Physical cosmology . For the journal, see  Astrophysics (journal) . Astrophysics  is the branch of  astronomy  that employs the principles of physics and  chemistry  "to ascertain the nature of the  astronomical objects , rather than their positions or motions in space". [1] [2]  Among the objects studied are the  Sun , other  stars ,  galaxies ,  extrasolar planets , the  interstellar medium  and the  cosmic microwave background . [3] [4]  Emissions from these objects are examined acro...
