The size of the capsules can be designed to stop at zones with various densities in the interstellar cloud.

Jeans instability is a physical state in which an interstellar cloud of gas will begin to undergo collapse and form stars.

Some interstellar clouds are cold and tend to give out EM radiation of large wavelengths.

Cyanopolyynes are relatively common in interstellar clouds, where they were first detected around 1970.

They are inside an interstellar cloud which makes them appear blue.

Less icy, perhaps, but even here, according to her tutor, the interstellar cloud had begun to have its effect.

Another hypothesis is that they formed from interstellar clouds and were captured by the solar system as it moved through space.

The maps confirm theoreticians' ideas on the birth of stars from interstellar clouds.

And here was something new to her: perhaps a new ice age would be triggered by the Earth's passage through an interstellar cloud.

An interstellar cloud is dust, plasma, or ionized gas in a galaxy.
