You can add another star to our solar system and watch it rip the planets from their orbits. The free forever version allows you to explore and discover any simulation. Optionally you can upgrade to to the premium version for unlimited control. Watch the Video

Your Sky by John Walker Welcome to Your Sky, the interactive planetarium of the Web. You can produce maps in the forms described below for any time and date, viewpoint, and observing location. Canister lets you add water (or bodily fluids) to recharge batteries SiGNa Chemistry Inc. is launching a hydrogen-producing cartridge, the mobile-H2™, that will work with a portable, pocket-sized fuel cell charger to provide instant power for cell phones and other mobile devices. You simply add water to the cartridge, and the device will charge depleted batteries on the go. For further convenience, any water will do (even waste water). Unlike solar battery chargers, you don’t need to worry about getting enough sunlight. According to its press materials, these cartridges provide a steady level of power from beginning to end.

Space.com Buy This Infographic as a Full-Size Poster Astronomers have discovered more than 700 alien planets beyond the solar system, and the count is rising all the time. Some are large and hot, and others are smaller and cooler, but scientists are still on the lookout for an Earth twin. They just got closer, with the announcement Dec. 5 of a planet found by NASA's Kepler space telescope to lie in the habitable zone around its star where liquid water, and perhaps life, could exist.

microscope photos These microscope pictures are taken from the book ‘ Microcosmos’, created by Brandon Brill . This book includes many scanning electron microscope (SEM) images of insects, human body parts and household items. These are the most amazing images of what is too small to see with the naked eye. 01 – A wood or heathland Ant, Formica fusca, holding a microchip 02 – The surface of an Erasable Programmable Read-Only Memory silicon microchip Mental Math Tricks to Impress Your Friends One thing that fascinates me is performing mental math. Being able to quickly perform additions, subtraction, multiplications etc is a good way to impress your friends. The problem is, I’m not a math genius, and I don’t know much behind simple arithmetic.

Your Age on Other Worlds Want to melt those years away?

MCEdit, a Minecraft World Editor MCEdit is an open source world editor for just about any version of Minecraft. MCEdit was first created to allow players to preserve anything built with several old versions of Minecraft and take them forward into newer versions of the game. It also aims to be forward-compatible with future (or even modified) versions of Minecraft. It has since been improved with brush tools for laying down blocks in different shapes, integration with the Minecraft Server to generate terrain using Minecraft’s own seed algorithms, support for multiplayer worlds, and editors for certain blocks including chests and mob spawners. To get an idea of what MCEdit can do, just watch this tutorial/walkthrough by a famous mapmaker:

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below.

The end of the net as we know it Posted on 21 Jan 2011 at 13:34 ISPs are threatening to cripple websites that don't pay them first. Barry Collins fears a disastrous end to net neutrality You flip open your laptop, click on the BBC iPlayer bookmark and press Play on the latest episode of QI. But instead of that tedious, plinky-plonky theme tune droning out of your laptop’s speakers, you’re left staring at the whirring, circular icon as the video buffers and buffers and buffers... That’s odd. How to Ace Your Finals Without Studying & Scott H Young I’ve never been that keen on studying before an exam. I rarely study for more than a half hour, even for big final exams worth more than half my grade. When I do study, I usually just skim over the material and do a few practice questions. For some of my math classes I have yet to do a single practice question for homework. Most people study by cramming in as much information before walking into the test room, whereas I consider studying to be no more than a light stretch before running. Despite what some might point out as horrible studying habits, I’ve done very well for myself in school.
