... The hotter the gas, the faster they move, and the more energy each of them holds. The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much , much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ...

. This image shows a prtion of the M23 field imaged by the Luther College team. Seven of the observed variable stars are marked. LCV22 and LCV24 are eclipsing binaries with stellar surfaces in contact. LCV15 is an eclipsing binary system with the stars well separated. Note that this star appears as 17505-1851.7 in the ASAS-3 catalog. LCV13, LCV20, LCV21, and LCV30 are long period pulsating stars. Provided by Luther College
