unusual facts about Interstellar medium


Southern Local Supervoid

The Southern Local Supervoid is a tremendously large, nearly empty region of space (a void).


Alpha Camelopardalis

Runaway stars such as this with a stellar wind that is moving at supersonic velocity through the interstellar medium have their wind confined by a bow shock due to ram pressure.

Solar wind

The solar wind flows outward supersonically to great distances, filling a region known as the heliosphere, an enormous bubble-like volume surrounded by the interstellar medium.

Presolar grains

In the mid-1970s, Donald D. Clayton predicted that unusual isotopic compositions would be found within thermally condensed grains produced during mass loss from stars of differing types, and argued that such grains exist throughout the interstellar medium.
