WebWe divide the interstellar medium into three types dependent on their temperature (called the phase of the interstellar medium): cold (10’s K), warm (100 to 1000’s K), hot (millions K). The colder a cloud of gas, the more of its output emission is in the long wavelengths; radio and microwave. Web17 jul. 2024 · It is hard to perceive how gas molecules are distributed in this whole space, however, this segregated distribution could be done pretty easily for its 3D spatial and velocity projections. For states near thermodynamic equilibrium, spatial projection appears pretty trivial: Point particles distributed randomly and evenly, on average ( Figure 1 ).

Web5 uur geleden · Jupiter and Saturn have such strong gravity that they stretch and pull the bodies orbiting them, causing moonquakes that can crack the moons’ crusts and surfaces.
