The total amount of ordinary matter, called baryonic matter, makes up for about 5% of the total matter of our Universe. The other 95% consists of the exotic dark matter and dark energy. However, even this 5% of baryonic matter is hard to detect! Only 60% of the baryonic matter has been observed! Now scientists, used ESA’s XMM-Newton X-ray space observatory and found evidence of where these missing baryons are!!
