Finally, Some Help

How to Detect Watery Worlds Around Other Stars
If you want to know what a watery world might look like orbiting another star, just observe our own planet… from afar. The Blue Marble image of Earth, taken by the Apollo 17 astronauts on December 1972, shows how our planet is 70% water. Another world like ours, orbiting a distant star should be obvious [...]
Comet Strikes Increase as We Pass Through the Galactic Plane
There are just so many ways the Universe is out to get us. Astronomers have already considered the threat from our Sun's orbit around the center of the Milky Way. When our Sun rises up out of flat plane of the Milky Way, it appears we might be less protected from intergalactic radiation and cosmic [...]

And true to form, it's another monster, with many many [...]
I’m using Twitter?
I signed up for Twitter a couple of years ago, but I never got around to actually using it. Some part of my brain thinks it would be a great way to do… something. But I have no idea what that would be. I'll need you to teach me, and help me understand what you'd [...]
Why Can’t We Launch Garbage Into Space?
Question: Why Can't We Launch our Trash Into Space?
Answer: Now wouldn't that be a tidy solution to a big problem? Gather together all the garbage, bundle it up and fire it off into space. Maybe just dump it into the Sun. We could live in a world without trash.
