... Mach 1, causing the gas within the bubble to become so intensely hot that the gas ionizes. This ionization produces a plasma at a sufficient high temperature that the plasma emits light waves near ultra violet frequencies. The temperatures are so high, some scientists have suggested that sonoluminescence temperatures approach the temperatures necessary for nuclear fusion. So long as the amplitude of the ... will quickly disintegrate. Other scientists disagree with this explanation of sonoluminescence. Professor Prosperetti believes that sonoluminescence is nothing more than the result o...

... of a neutron star, the gas forms a disk around the compact star. Within the disk, collisions and friction between the atoms of gas convert the energy of its orbital motion into heat energy. The gas loses altitude as a result, spiraling lower and lower and moving toward the center of the disk. As the gas approaches the inner edge of the disk (edge ... near the black hole), the temperature rises. This heat energy being produced is then radiated as X-rays. Deep in the Milky Way galaxy's core is a mysterious and powerful source of radio waves known as Sagittarius A* (Sagittarius A star). As...
