If you plan on taking a trip to Jupiter, this is not the map to use.

Indirect fusion's nothing less than HiiiPoWeR

Installed solar capacity is growing by leaps and bounds, led by Walmart and Apple, and helped by bonds backed by solar power payments,[*] which have sent industry stocks soaring, even as molten salt and new battery technologies come on line to generate storage for use when the sun doesn't shine. Of course we could always go to geostationary orbit -- or the moon -- as well we may (if politics allow it) as thirst from the developing world grows beyond the earth's carrying capacity.

How Hou Yi Shot The Suns

"The sun descending in the west, The evening star does shine;"

Have you ever wondered what a solar eclipse would look like from space? The STEREO (Solar TErrestrial RElations Observatory) has just sent back its view (awe-inspiring video included). It has also sent back some gorgeous pictures of our sun (and the McNaught Comet). For more media, check out the other galleries (including some 3D images). For more about the project, see NASA's STEREO homepage. Be sure to also stop by the Johns Hopkins University STEREO Page, where you can download a mission guide (pdf), view animations, watch a video of the launch, or even make your own papercraft STEREO model (pdf). You can also learn more in six minute segments with their series of short educational videos.

Blowing up the universe.

How to blow up the Earth (with a coffee can), and why we should, along with some discussion of how it is done in fiction. Blowing up the moon (and how the US nearly did in 1958, with the help of Carl Sagan), and lots of reasons why, including one in song [YouTube]. How to blow up a star. How we might accidentally blow up the universe in November. [prev. discussion of Earth destruction]

A New Kind of Solar Storm

Going to the moon? Be careful. A new kind of solar storm can take you by surprise. Biggest proton storm since 1956 - before there were satellites monitoring the sun.
