Meteor Shower
The Geminid meteor shower peaks on Dec. 13th and 14th.
Bright moonlight will interfere with the display, but not obliterate it. Forecasters expect observers with clear skies to see as many as 40 meteors per hour.

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.

Boeing has already developed a manned airplane powered by hydrogen fuel cell. The plane has minimal noise and causes almost no air pollution. 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.
