Go out, grab a piece and bring it home.
Planets that formed over 10 billion years ago are about 5 billion light years from us, meaning that if we could somehow study planets that far away (we can’t) the light reaching us from there would have taken 5 billion years to reach us. Therefore, we’d be seeing what the planet looked like 5 billion... Continue Reading →
I don’t see either as being dependent on the other. In other words, you can believe in God and not in extraterrestrial life. Many religious people do in fact hold that view. On the other hand, you can believe in extraterrestrial life and not believe in God. I know many people who hold that view.... Continue Reading →
Transmissions from Mars to Earth and visa versa happen at the speed of light. However, Mars is sometimes near Earth and sometimes on the other side of the sun. Therefore, depending on where Mars is in relation to Earth in our orbit around the sun, transmission times change from 4 minutes to 24 minutes. If... Continue Reading →
When you look into a telescope at the galaxies and stars you are looking back in time, because it took time for the light of those objects to reach you. If it took 13 billion years to get you then you'd be seeing light that originated 13 billion years ago. If you could see clearly,... Continue Reading →
We have no proof life exists anywhere in the universe other than Earth. Given a planet with the right conditions, life can spring from matter and eventually evolve into something greater is the wet dream of science, but still an unproven theory.
Proxima Centauri, is our nearest star, about 4 light years away. A light year is the distance light travels in one year, or 9,460,730,472,581 kilometers. That's 9.46 trillion kilometers, or about 5.88 trillion miles. The fastest space ship we ever built was the Juno spacecraft, which in 2016 broke all speed records in space with a...

In 2035, to be precise. It's a Thursday. It looks something like this and is about the size of the Empire State Building. If it does hit us it's going to destroy a lot of things on the planet, but not kill us completely. It's not an extinction event, just a big bad event. Bennu... Continue Reading →
Answer by Award-Winning Scifi Author C Stuart Hardwick "We” have. You presumably missed the memo. The far side of the moon was first photographed by Luna 3 in 1959. The above is a recent image captured by NASA’s LRO. If you are asking why we can only see the near side from Earth, that’s because the... Continue Reading →
