Massive stars could house planets that have simple life, but complex forms and civilisations are unlikely to emerge. They also emit more energetic radiation than our Sun, which can damage the DNA of life that does develop, rendering it unable to survive. Stars beyond 1.4 solar masses do not live long enough for complex life to evolve on a planet.There is a multitude of reasons for why more or less massive stars are not optimum for the development of life. In other words, stars capable of supporting habitable planets have masses between half the mass of the Sun and slightly less than one-and-a-half masses of the Sun. Generally speaking, the range of stars that may be suitable for the development of habitable planets is between 0.5 solar masses to 1.4 solar masses. The ScienceNot all stars are friendly for the prospects of life. Common questions and misconceptions regarding the conditions for habitability. A step-by-step walkthrough of creating a realistic habitable planet in Universe Sandbox ².ģ. Outline and explanation of the factors that influence the habitability of a planet.Ģ. Taking these aspects into consideration, this guide will focus on the following areas:ġ. This is what this guide aims to teach you to do. To build a true habitable planet, we must incorporate factors that affect habitability in our real universe into the simulation, based on scientific studies.
The word "realistic" has been stressed because Universe Sandbox ² uses simplified models for determining a planet's habitability and so it is relatively easy to create a planet that seems habitable according to the game's calculations, but really isn't. There are far more factors than you might initially suspect responsible for determining whether a planet is realistically suitable for life. Choose a star, plonk down a rocky planet in its habitable zone, add an atmosphere and some water and we've succeeded, haven't we? Not quite. One of its most prominent core features is the terraforming of desolate, dead planets into a second Earth marked by the footprints of life.Ĭreating a habitable planet doesn't seem too difficult a task. With the ability to mould the cosmos at your will, Universe Sandbox ² holds countless possibilities and potential.
