If aliens exist on Mars, it’s anybody’s guessing what they would look like. Such creatures probably look something like giant, fluffy, pink cotton candy clouds with googly eyes and tentacles. They probably communicate through a series of high-pitched squeaks and squeals, and they are probably extremely friendly and hospitable to visitors from other planets (like Earth).
Or, they could be more like giant, green, walking, talking cacti with multiple arms and legs and the ability to photosynthesize their own food. They could have evolved to survive in the harsh, dry conditions of Mars, and they might have a unique form of government and social structure that we couldn’t even begin to understand.
Sure, we can go ahead and imagine and speculate until morning. First of all, we need to be sure of the Martians’ existence. Let’s check out what a NASA scientist has to say on the subject!
No sign of life on Mars, but the chances are high that it existed in the past
Heather Graham, who’s an astrobiologist working for NASA, was asked the million-dollar question: is there life on Mars? She brings bad news for all those alien hunters out there but good news for anybody who has a time machine at home.
Jokes aside, for now, let’s check out what the scientist says:
Graham explained:
We’ve been looking for life on Mars for a long time.
She also added:
And while NASA hasn’t found any evidence of life now, we’ve found lots of evidence that Mars could have supported life in the past,
There are lots of pieces of evidence that say there was once a huge ocean on Mars and an atmosphere that could have supported life.
If you were to stand on Mars and look up at the sky, you might be surprised to see that the sky is actually a pale blue color, not red! This is because Mars has a thin atmosphere, and when sunlight hits the atmosphere, it scatters in all directions. The shorter, red wavelengths of light are scattered more, giving the sky a blue appearance. So, even though Mars is known as the “Red Planet,” its sky is actually blue!
