The invisible universe
A new part of the universe has just been discovered.
quote from: http://www.sciencedaily.com/releases/2014/11/141106143723.htm Using an experiment carried into space on a NASA suborbital rocket, astronomers have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe. The discovery suggests that many such previously undetected stars permeate what had been thought to be dark spaces between galaxies, forming an interconnected sea of stars. end quote The explanation advanced by the observers implies evaporation of stars from galaxies, forming a halo around all galaxies.

The invisible universe

[snip to easy the moderator's work :-) ] P.S. A while ago I brought into this forum the incredible fact of a million year diameter disc around Andromeda and many other galaxies. Now, could it be that those "halos" now discovered are actually DISKS? The mass contained in those discs would be equivalent to the mass of the galaxies themselves. Then, going on with this reasoning, wouldn't the discs exerce a gravitational attraction to the stars in the galaxies proper that would explain their anomalous movement at the edges of the galaxies? That was one of the main reasons to postulate dark matter! |

Comment from Perspective(?) in Science: "It is remarkable that such a major component of the universe could have been hiding in plain sight as an infrared background between the stars and galaxies." Remarkable - Yes! Surprising - Not to everyone. [Mod. note: Reformatted. Indeed, there have been plenty of observations pointing in this direction in the past -- mjh] |
