Why do scientists think there might be life on earth like planets when aliens might survive hot temperatures with no water?

Good point. Great question. We just look for the most “likely” places life might develop. Interestingly, though, there are lifeforms like the ones you describe here on Planet Earth! You can find these lifeforms in Chile, specifically the Atacama desert. This place is burning hot and has had no significant rainfall in at least 250 years. According to express.co.uk “While...

Space Debris – A Dodging Problem

This is a no frill video (no audio) produced by scientists, to depict just how much junk "litter" we have floating around up in space, some of it going 35,000 miles per hour. Just something to think about.

Breaking news. Astrophysicists have discovered a new planet within the “Goldilocks” region orbiting a yellow dwarf star and believe it is teaming with life, thus putting to rest the age-old question: “Is there life on other...

If you launched a satellite into low earth orbit and let it travel indefinitely without course corrections, how long would it take before it hits another object?

Okay, your question is how long until it hits another object also in low earth orbit, AKA space debris. In low Earth orbit you are not completely above the atmosphere, though it’s pretty thin up there. Most objects we place in orbit don’t need course corrections and likely succumb to the ever so slight air... Continue Reading →

Given that NASA has landed on the Moon, why did they not put some plants on the lunar surface?

Wow. What would have happened if astronauts had brought plants to the moon? Surely by now the moon would be green! Here I always thought the thing was made of blue cheese. You must know from the other answers that there’s no air on the moon and plants need air to survive just like you do. Another... Continue Reading →
