The mean ISW imprint 50 supervoids have on the Cosmic Microwave Background: [9] [clarification needed] color scale from -20 to +20 μK.. One possible explanation of the cold spot is a huge void between us and the primordial CMB.
Southern Eridanus Void: The Southern Eridanus void is connected to the Eridanus void by a hole in the distribution of galaxies separating the two. A hole in the distribution of galaxies separating Sculptor and Southern Eridanus voids the size of (redshift) 1250 km/s appears to exist. [11] Fornax Void: Hercules Void: 15.5 h +30° cz=7000 km/s ...
Eridanus Supervoid: 489,000,000 (most likely value) A recent analysis of the Wilkinson Microwave Anisotropy Probe (WMAP) in 2007 has found an irregularity of the temperature fluctuation of the cosmic microwave background within the vicinity of the constellation Eridanus with analysis found to be 70 microkelvins cooler than the average CMB ...
The Orion–Eridanus Superbubble or Eridanus Soft X-ray Enhancement is a superbubble located west of the Orion Nebula. The region is formed from overlapping supernova remnants that may be associated with the Orion OB1 stellar association; the bubble is approximately 1200 ly across. [ 1 ]
Eridanus Supervoid — 500 million light years 5 × 10 24 meters Distance to the Shapley Supercluster — 650 million light years 6.5 × 10 24 meters Pisces-Cetus Supercluster Complex — 1 billion light years 10 25 meters Sloan Great Wall — 1.3 billion light years 1.3 × 10 25 meters Gigaparsec — 3.3 billion light years 3.3 × 10 25 meters

Eridanus (constellation), a southern constellation; Eridanus Cluster of galaxies in the constellation Eridanus; Eridanus II, a low-surface brightness dwarf galaxy in the constellation Eridanus; Eridanus Supervoid, a large-scale cosmic underdensity
The Eridanus Group, sometimes called the Eridanus Cloud, is a nearby loose grouping of galaxies at a mean distance of approximately 75 Mly (23 ± 2 Mpc) in the constellation Eridanus. [1] Redshift values show that there are approximately 200 galaxies associated with the group, approximately 70% of which are spiral and irregular type galaxies ...
