These may be the darkest points in outer space

The question of darkness has long fascinated humanity, and with the advancement of space exploration, it is only natural to wonder whether outer space might contain a uniquely dark point against which everything else appears bright or illuminated.

For most people, space is imagined as a fundamentally dark, desolate, incomprehensible void, about which our knowledge remains sadly limited — far more questions exist than available answers.

It is therefore reasonable to ask whether space truly is as dark as it seems at first glance, and whether there is a single point darker than all others. According to space researchers, answering this is complicated by the fact that what we consider “darkness” depends on an enormous number of factors, LiveScience reports.

Total darkness is rarer than you might think

Although the space between stars appears pitch-black at first sight, vast amounts of dust are present throughout the cosmos, scattering and transmitting light. This means the night sky appears far brighter than it would if its illumination depended solely on starlight.

Because this creates the effect of a kind of background lighting filling much of the universe, true absence of light is extremely rare. Moreover, the basic colour of space is not black at all, but a slight beige tone — often referred to in scientific circles as “cosmic latte”.

According to Andreas Burkert, an astrophysicist at the University of Munich, precisely defining the concept of darkness may be the key. Visible light is not the only wavelength in the electromagnetic spectrum — gamma rays and UV radiation also reach distant parts of the universe, meaning there may be light present even where our eyes perceive only darkness.

Can darkness be measured?

If we consider only visible light, we can indeed identify distinctly dark places in outer space, and their measurement can be aided by the concept of albedo.
