intrahalo light discovered

Spotted a reference to an article about rogue starts. I think initially I saw it on the SETI Facebook wall. Looks like the article proper is on Space.com.

Very interesting. It suggests that half the stars in the Universe lie outside galaxies! Wow. That's a lot. Possibly  pulled from their host galaxies by collisions and mergers and tidal interactions.

This is the result of a NASA near-infrared experiment called CIBER where an area of the sky was studied, the light from the galaxies was removed, and what remained was studied. Very high levels of blue light was found.

The newly discovered stars might account for some missing photons as well as some missing baryonic matter.
