The temperature of the darc spaces can sometimes hike to extremely hot temperatures. Some amount of energy due to trapping matter inside is liberated and turned into light which can be seen in X-rays.
A piercing type of high-energy electromagnetic radiation is called X-radiation. The majority of X-rays have a wavelength between 10 picometers and 10 nanometers, which equates to frequencies between 30 petahertz and 30 exahertz.
X-ray scans show that a galaxy cluster's intergalactic region is extremely hot. This is due to the fact that the intergalactic medium, also known as the intergalactic media, is primarily composed of heated, ionized hydrogen with traces of heavier elements like silicon, carbon, and oxygen.
Instruments to detect X-rays must be transported to high altitudes by balloons, sounding rockets, and satellites since X-radiation is absorbed by the Earth's atmosphere.
