Question

You are the leader of a scientific research team on an extra-terrestrial planet. One of the junior members tells you the plants are actually orange in color instead of green. You tell this individual that it makes sense since the sky is purple. Explain your reasoning.

Answer 1

Answer:

Explanation:

"The vegetable kingdom in Mars, instead of having green for a dominant colour, is of a vivid bloodred tint." H G Wells's vision of Martian plant-life in his science fiction epic The War of the Worlds turned out to be wrong, but Nasa scientists now think they can predict what colour plants on alien planets will be - if they are out there.

The idea behind the research is that if you want to find evidence of life in the cosmos you need to know what you are looking for. The researchers have worked out which wavelengths of light would hit the surface of potential life-bearing planets in other solar systems and so worked out what kinds of light-gathering pigments plant-like organisms would need to exploit them. And their results are truly alien, with predictions of purple and yellow-orange vegetation on some other worlds.

Answer 2

Answer:

In place of green, the vegetation are orange and the sky is purple. - The orange colour of plants is caused by the combined wavelengths of red being absorbed.

Explanation:

Why is the sky blue and not purple?

• Since violet light makes up a small percentage of the solar spectrum, there is simply less of it to disperse, and, possibly relatedly, human eyes aren't very good at perceiving violet light, violet light is scattered by the atmosphere just as much as or more than blue light.
• It makes sense if humans developed on a planet where blue light (and its neighbour green) are more prevalent in sunshine than violet light since we're not nearly as sensitive to it as we are to blue light.
• Even if humanity were to inhabit a planet around a much hotter star, the sky would most likely have a deeper bluish-purple hue.
