Recently there have been up to two habitable planets discovered around the star TRAPPIST-1, if animal life was able to evolve on either planets how would eyesight evolve under such a dim star? How ...
Let's say an alien species discovered Earth and wants to land here and establish contact, however their homeworld's gravity is only 46 percent of Earth's, Would it be possible for them to be able t...
The gas giant has a mass of about 2.13 Jupiter masses in the habitable zone of a Sun like star 0.981 Sol masses, all the moons will need at least >0.12 percent of Earth's mass and a Mars like de...
These moons orbit a Jovian planet with 0.52 Jovian mass and at 1.02 AU from a star with 0.98 Sol mass. 3.85 Days, 0.351 Earth, 0.68 G 15.4 Days, 0.242 Earth, 0.59 G 30.8 Days, 0.118 Earth, 0.44 ...
In Halo series there is an intelligent race called Unggoy that evolved on a planet caled Balaho orbiting a blue supergiant called Tala, I would like to know if it would be possible for an intellige...
Would it be possible to have alien life use Hydrogen sulfide instead of Water? I assume they are still carbon based. Also for a sunlike star what distances should this planet or moon be located?
Would it be possible to replace water with hydrogen peroxide on an Earth like planet? I know water and hydrogen peroxide are similar, Also if this configuration is possible what may cause an Earth ...
Assume that the atmospheric concentration is still the same 78.09% nitrogen, 20.95% oxygen etc, except now just as dense as the Venusian atmosphere. Would humans be able to survive in this atmosphe...
In the Mass Effect series there's a terrestrial planet called Dekuuna with 10 times the mass of Earth, a surface gravity of 4G and a native intelligent race. I was just wondering if it was possible...
I know water would be out of the question, but what about liquid nitrogen or liquid hydrogen, Would silicon work instead of carbon?
Watching E.T. I was wondering what evolutionary factors could cause a species to have the appearance of E.T., like the environment he would likely live in and the gravity of his homeworld.
For the following stars -A Class -F Class -G Class -K Class -M Class What are the most likely skin tones for each type of stellar class? Also for their eyesight how different is it to vary ...
In the Halo series there's a habitable planet called Harvest with a diameter of 4,012 kilometres, and gravity 99% of Earth's, though the planet only has 9% of Earth's mass. If such a planet is poss...
This one source is stating a desert planet the size of Earth could maintain habitability at 0.38 AU from a sun-like star, but I highly doubt this is possible. What are some factors that could make ...
The host star for this hypothetical system is 1.05 (M☉) The gas giant is 20 percent more massive than Jupiter and orbits at 1.40 AU, now I need to know if these three orbits are stable around th...
The host star has a mass of 0.90 M$_\odot$ I'll refer to this star as Helios. I'll refer to the planets as Helios One, Helios Two, etc. Helios One is 0.55 M$_{\oplus}$ and orbits at 0.75 AU. It's ...
If yes, what are some possible ways they could break through the ice and explore the surface?
