WebJul 28, 2024 · Cosmic dust, which collects in galaxies in loose fogs or thick clouds, has often plagued astronomers. The tiny grains, each 10,000 times smaller than the eye of a needle, absorb light, scatter it ... WebWhen dust is carried on air currents generated by air conditioning and similar devices, the dust takes on a positive or negative static electric charge due to contact with various objects. Dust that has a positive electric charge will be attracted to objects that have a negative electric charge, and vice versa.

For sub-GeV to ∼103 GeV cosmic rays, small-scale parallel Alfv{\'e}n waves, which isotropize cosmic rays through gyro-resonant interactions, are also gyro-resonant with charged grains. WebApr 11, 2024 · When this dust accumulates in a single location, the result is a dark cloud where ultraviolet starlight is blocked and molecules can survive. The largest of these structures are created where gravity pulls interstellar gas together to form giant molecular clouds, structures as massive as a million times the mass of the Sun. northern tools macon georgia
