Imagine the following scene: you are in a dark room, with all the windows and curtains closed. Suddenly, a ghostly and mysterious glow takes over the entire environment. Calm down, everything is just a dim light that barely illuminates. No need to be scared! well the telescope hubble found a similar glow in the Solar System.

According to astronomers, the light is equivalent to about ten fireflies in a night sky. To track down what the apparition was about, scientists looked at 200,000 images from the Hubble archives, took several measurements and investigated any afterglow that appeared since then.
Through image edits, they took out the light from stars, galaxies, planets, and zodiacal light (a faint glow of sunlight scattered by interplanetary dust). In the end, manage to leave this faint glow to study it.
What is the mysterious glow spotted by Hubble?
According to information extracted from SciTech Daily, scientists still don't have the answer, but the good news is that luckily they already have some hypotheses!
One possibility is that the ghostly light is a reflection of sunlight on cosmic dust. You know when you are cleaning in a very dusty place, so the dust that is suspended in the air is reflected by the sun? It's like that.
As the glow is softer, scientists believe that its origin is another. It is likely that this mysterious light has its origin in comets, which are nothing more than dusty snowballs flying through outer space.
Dust is expelled from these celestial bodies as the ice sublimates with sunlight.
a new possibility
In 2021, another team of astronomers used data from NASA's New Horizons spacecraft to measure the sky background from space. This spacecraft also detected a small glow, slightly fainter, in a more distant light source than the one found by Hubble.
This glow is also of unknown origin, however it is believed to be an extra light from within our Solar system. As the one detected by Hubble is stronger, they are assuming that its origin is around here.
Therefore, external sources are practically ruled out.
