We live in a universe filled with light, but
astronomers have long wondered howmuch of the light comes from visible stars
and galaxies, and how much of it is near-infrared

Now, a team of researchers led by scientists at the
Max Planck Institut has developed a way to tease
apart these two types of light, writes space.com.
The universe's near-infrared light comes from a com-
bination of observable galaxies and stars and also very
ancient objects like the first stars ever formed. The sum
of this light, which is the light emitted from all objects
throughout the universe's history, is called the extra-
In addition, "foreground light" is emitted by dust in
the solar system, which radiates light in the same
wavelength and makes it difficult for scientists to
figure out how much light comes from each source.
The trick is to measure the star light in the space
between galaxies, where there is no foreground light. pass. The Hubble and
