Have astronomers found the missing mass in the Universe?
... web. Until about thirty years ago, astronomers thought that the Universe was composed almost entirely of "baryonic matter" – ordinary atoms made up of protons, neutrons and electrons. But, after calculating the density and composition of the...

Telescope targets enigmatic deep space mystery
... that 95 percent of the Universe is composed of dark energy and dark matter and only around five percent is ‘baryonic matter’ or normal matter, since its constituents are atoms. Baryons make up objects of everyday life, however only 50 percent are...

Mini-spiral galaxies may transform how dark matter is perceived
...Karukes. "Our observations, however, disagree with this notion." Non-baryonic matter are particles such as electrons or neutrinos, which are classed as leptons. Baryonic matter on the other hand is made up of particles found in an atomic nuclei, such...

Researchers create largest-ever 3D map of the Universe
... oscillations (BAO), which are regular, periodic fluctuations in the density of the visible baryonic matter (normal matter such as protons and electrons) of the Universe. These oscillations are analogous to sound waves created in air by pressure...
