Star systems can only be traversed via a web of faster-than-light routes called hyperlanes, while habitable planets hold populations of an empire's citizens – represented by "pops" – and can be built up with buildings and districts that produce resources or other passive effects as long as there are enough pops to fill the available jobs.
Many hypothetical doomsday devices are based on salted hydrogen bombs creating large amounts of nuclear fallout.. A doomsday device is a hypothetical construction — usually a weapon or weapons system — which could destroy all life on a planet, particularly Earth, or destroy the planet itself, bringing "doomsday", a term used for the end of planet Earth.
The concept is depicted in the video game Stellaris, where players are given the option of transforming planets into ecumenopolises, which provides a great deal of housing and space for industrial production through the construction of arcologies, at the cost of making the planet's natural resources inaccessible.

Another issue is the crashing of abandoned orbital debris on extraterrestrial planets. Before the 21st century, exploration of other planets in the Solar System raised little concern about contaminating planets with life from the Earth. Since then experiments have shown that some terrestrial life is astonishingly hardy, and the time spent in ...
Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.. Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain an environment hospitable to life. [1]

A former Allianz fund manager was spared prison time on Friday over his role in a meltdown of private investment funds sparked by the COVID-19 pandemic that caused an estimated $7 billion of ...
This is a list of exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky. [3] [1] Note that inclusion on this list does not guarantee habitability, and in particular the larger planets are more unlikely to have a rocky composition. [4]
