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 researchers, including Caltech Professor of Physics Jamie Bock and Caltech Senior Postdoctoral Fellow Michael Zemcov, say that the best explanation is that the cosmic light — described in a paper published November 7 in the journal Science — originates from stars that were stripped away from their parent galaxies and flung out into space as those galaxies collided and merged with other galaxies.

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. (1)

We live in a dark world. With small specks of light here and there.
Enough to light up everything.
Even the darkest night, is afraid of the smallest light.
Somewhere in a galaxy far far away, a small candle is lit. And even though you cannot see it, it makes the night warmer in a way totally incomprehensible…

Take my hand.
I will leave the light on.
