The latest resarch postulates that only about 5% of our universe is made of normal matter as we know it, consisting of protons and neutrons, or baryons, which along with electrons, form the building blocks of ordinary matter. The rest of our universe is composed of elusive dark matter (23%) and dark energy (72%). Astronomers using the European Space Agency (ESA) XMM (X-ray Multi-Mirror) Newton Observatory have now uncovered part of the missing matter in the universe.
