  Uh wow! Mouth dry! Mouth dry!

  I actually watched that episode last night, so that post was kinda jumping at me. What are the odds…

  Sagan, a real teacher. Not only smart, there are quite a few smart people. But also able to make something complicated easily understood. To make something abstract sound straight. To make something minds can’t grasp comprehensible. A beautiful ability!

  Interesting, thank you for the reply! Learned something new today. The lines I see span over a quarter or so of the moon, so I’m not fully convinced yet. Absolute massive.

  Ah, this is probably the right community to ask.

  What are those stripes leading to the crater, here in the upper left?

  I’ve noticed them before, but when I try looking it up, I usually only find results for Saturn’s moon.

  Beautiful picture, op!

  I recently read somewhere that it’s actually just very few bee species that die after stinging, among them honeybees. They have a barbed stinger that gets stuck while most bees have flat stingers and can sting repeatedly.

  Regarding solar electricity: does that mean to mirror the sunlight to a solar panel? If so: ignoring, that one would constantly need to adapt the mirror’s position, I think I also read somewhere that solar panels decrease efficiency with heat. So my question is: could one increase solar panel output by bundling light or would heat related inefficiency cancel that out?

  I don’t know where you live. But where I live, styrofoam costs next to nothing. In fact, you get it for free, if you don’t mind looking through another man’s trash. You can also probably get some for free if you ask a company, that gets stuff sent, that need cooling. Like a supermarket.

  For environment: styrofoam is a kind of plastic, so there is that. On the plus side, it’s quite little plastic inflated with air.

  I assume it’s way better than getting a replacement fridge, especially considering the electronics and maybe the coolant gas (I don’t know if that’s still an issue).

  I wouldn’t be surprised if the electricity saved alone offsets the environment damage (assuming not fully green power used to run the fridge).

  It’s not any snake, but some species that are adapted to living on trees. It’s also not really flying. Gliding would describe what they do better. As they jump, they flatten their body and make slither movements through the air, gliding maybe at a 45 angle downwards.
