Galactic missing matter — one of the greatest mysteries in astrophysics — may have been found by a student astronomer
By James Maynard
Astronomers have known for decades that around 95 percent of all the mass in the Cosmos consists of dark matter and dark energy. Just five percent of all-there-is can be found as baryonic (normal) matter.
A long standing mystery in astrophysics is that when astronomers add up the masses of every star and cloud of gas they see, it still only adds up to half of the baryonic matter known to exist in the Universe.
“We suspect that much of the ‘missing’ baryonic matter is in the form of cold gas clouds either in galaxies or between galaxies. This gas is undetectable using conventional methods, as it emits no visible light of its own and is just too cold for detection via radio astronomy,” Yuanming Wang, a doctoral candidate in the School of Physics at the University of Sydney explains.
