Default 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.

How little we know about the cosmos really.

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]
