Every time you get upset about something small, just remember this.
(The “Moonrise” should get a rise out of some of you!)
“Great Attractor is a gravity anomaly in intergalactic space. The first indications of a deviation from the uniform expansion of the universe were reported in 1973 and the location of the Great Attractor was finally determined in 1986 to be located 250 million light years from the Milky Way in the direction of the Hydra and Centaurus constellations.
“This region of space is dominated by the Shapley Supercluster, the largest concentration of galaxies in our nearby Universe, forming a gravitationally interacting unit that is pulling itself together instead of expanding with the Universe. Many of the older galaxies within the Shapley Supercluster (named after a man, not after its shape!) are colliding with their neighbors, and/or radiating large amounts of radio waves.
“Observations of this group of galaxies indicate that they are receding relative to us and to each other. The variations in their speeds cover a range of plus or minus 435 miles per second (+700 km/s to -700 km/s), depending on their angular deviation from their direction to the Great Attractor.
“Attempts to study the Great Attractor and other phenomena are hampered due to line-of-sight obstruction by its location in the ‘zone of avoidance,’ the part of the night sky obscured by the Milky Way Galaxy.”
