Talking about the Overview Effect. How astronauts often find that looking at the Earth from space is a life changing experience.
It's kinda long, 20min. But a pretty good video.. Link added to turn off autoplay.

http://boingboing.net/2013/02/21/graphene-supercapacitors-could.html A battery can hold a lot of energy, but it takes a long time to charge it. A capacitor can be charged very quickly, but doesn't hold a comparable amount of energy. A graphene supercharger is the best of both: it takes just seconds to charge, yet stores a lot of energy. Imagine being able to charge your spent laptop or phone battery in 30 seconds, and your electric car in a few minutes. Also, unlike batteries, Graphene supercapacitors are non-toxic. The Nobel Prize was awarded to the inventors of Graphene in 2010. Wikipedia defines Graphene as a "substance composed of pure carbon, with atoms arranged in a regular hexagonal pattern similar to graphite, but in a one-atom thick sheet. It is very light, with a 1-square-meter sheet weighing only 0.77 milligrams." from Focus Forward Films on Vimeo. |

I never thought of a capacitor as a battery substitute. Interesting. I'm not really in tune to the work that's being done in the area, but I've thought for some time now that battery technology is something that needs to make a large leap forward. You know: smaller, lighter, more capacity, etc.

That kind of makes sense, but kind of doesn't. If I laid out 10 crayons unlabeled and asked 100 people (not including blind or color blind people) to pick out a red one, all 100 would pick out the same one. Doesn't that mean they all have the same interpretation of red?

I added spoiler tags to the above gifs to avoid slowing the thread down. Here is an explanation of them:
http://blogs.smithsonianmag.com/smar...seenebulaein3d Stunning photographs of the cosmos, like the wondrous images captured by the Hubble Space telescope, convey the beauty that arises from the simple interactions of dust and light and gas on absolutely massive scales. Missing from photos of the universe, however, is a sense of depth: These stunning nebula are not a paint splatter on a celestial canvas, but truly massive constructions hanging in the void. Working from his own photographs of far-off nebulae, astrophotographer J-P Metsävainio came up with a way to artificially add in the third dimension. From there, he’s produced gorgeous animations of voluminous nebulae. (The files are quite big, so you might have to give it a second.) The images, says Phil Plait, on his blog Bad Astronomy, are “not actually showing you the 3D structure of the nebula. It’s an approximation, a guess based on various assumptions on how nebulae are shaped. J-P broke the image up into layers, made a surface model of it, then remapped it all into different frames seen from different angles. He then put those together to make the animated GIF you see here.” First, Metsavainio collects information about how far away an object is, and carefully studies the stars and structures in and around it. Then, he creates a volumetric model of his subject — usually a nebula, although he’s rendered at least one globular star cluster. Finally, he animates the 3-D rendering, providing viewers with a tantalizing taste of what it might be like to fly a starship through these enormous astronomical ornaments. |

listo I love the astro anarchy guy. He rocks, I love how he does the 3D stuff.
He's my pictures of the Lagoon and Heart Nebula along with the Pacman Nebula. Especially in the Pacman Nebula in the center, some cool views. Links added so it doesn't kill thread Warning large pics http://re-prop.com/apod/Heart_Nebula.jpg http://re-prop.com/apod/pacman.jpg http://re-prop.com/apod/m8-lagoon.jpg
