If you count all the little nuts, bolts, loose wrenches and pieces of demolished satellites as satellites, then there’s a whole lot of junk floating around Earth. Thousands of pieces that pose a hazard. Around the moon we have about three functioning spacecraft but have launched far more than that that have, over time, gone... Continue Reading →
We spend 600 billion dollars every year on the military. What would happen if NASA had that kind of money? Here's a very cool YouTube video that I love to watch!
Mechanical, intentional interstellar travel is unlikely since the distances are far too great to imagine. The best anyone could achieve is interplanetary travel within one’s own solar system. Therefore, if we pass the buck and say life didn’t start here but started somewhere else and arrived here, it would have had to arrive on a... 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...

The four gas giants are larger than Earth: Jupiter, Saturn, Uranus and Neptune. Venus is slightly smaller, but very nearly the same size as Earth. Mercury and Mars are smaller than Earth. So there are 4 planets larger than Earth in our solar system, and they are the four gas giants.
Are there other conscious-minded creatures on another planet or solar system? It is highly likely. Yes. Do we know for sure? No. We have no proof as of date of any life outside our tiny little Earth. We don’t even have any evidence of past life from anywhere other place than Earth. Will we ever... Continue Reading →
As Bobby Sherman has already pointed out, we have sent spacecraft to the surface of Venus and Mars. We’ve also sent people to our moon and a lander to Titan orbiting Saturn. We’ve retrieved photos from all these places. Here they are. First, our sister planet Venus (sister because it’s almost the same size as... Continue Reading →
