A fact is a simple statement that everyone believes. It is innocent, unless found guilty. A hypothesis is a novel suggestion that no one wants to believe. It is guilty, until found effective. ~Edward Teller

Total Lunar Eclipse Tonight
The shadow of the earth is expected to pass between the sun and the moon beginning about 12:29 a.m. Tuesday, and will fully eclipse the moon in about 72 minutes. The entire eclipse should be completed by 4 a.m. for those watching in Michigan.
Weather permitting, a lunar eclipse will be visible from 1:33 to 5:01 a.m. ET Tuesday, with the total eclipse starting at about 2:41 a.m., according to NASA.
The eclipse happens to be on the day of a solstice (first day of winter for the Northern Hemisphere; first day of summer for the Southern Hemisphere).

Hybrid Airplanes
The airplane can be hybrid i.e powered with fuel and electricity. The concept of using the combination of fuel and electricity to power the airplane seems a nice idea but it also has certain drawbacks. Boeing has already developed a manned airplane powered by hydrogen fuel cell. The plane has minimal noise and causes almost no air pollution.
In today’s time, traveling by air is the fastest and the most convenient way of getting from one place to another. Aircraft manufacturers are continuously researching and trying to build planes with more capacity, less maintenance costs and better fuel economy. If an airplane is highly maneuverable, it is designed to be unstable.

One of other interesting project i.e Sunseeker is a solar powered airplane by Eric Raymond. Hybrid planes have a high initial setup and building cost as compared to maintenance.
There are also concepts of gravity powered airplane which are out. They fly with force of gravity and don’t need any fuel. The idea is a bit far-fetched for commercial airliners but is worth reading.

The Anyman Astronomer
In college its very hard to get into Astronomy-having to buy expensive equipment and dump hundreds of dollars into equipment that we sometimes dont even know how to use. A simple solution to this is to pick up a pair of Astronomy oriented binoculars. Most Objects are able to be seen by these and they are a cheap, grab and go solution to not being able to get out and watch the night sky. For under $400, you can have a portable scope that will travel with you wherever you go. Check out The Vixen range for some great Sky Binocs!!!!!
"Vixen OpticsVixen Optics announces the new Foresta Binocular series. Of particular interest to amateur astronomers is the Foresta 7×50 ZCF model ($329). These lightweight binoculars feature die-cast aluminum bodies encased in a protective rubber coating. The 50-mm, three-element objective lenses and BAK4 prisms are fully multi-coated to minimize light scatter and maximize light transmission. The binoculars are nitrogen-purged to reduce internal fogging, and they are waterproof. Smaller models feature a novel hinge-lock that allows you to preset your interpupillary distance so that it can be quickly returned to a comfortable position after sharing the views with other observers. The binoculars come with lens caps, neck strap, and a hiking-style carrying case. "
