What is a constellation?
A constellation is a group of visible stars that form a pattern when viewed from Earth. The pattern they form may take anything from the shape of an animal, a mythological creature, a man to an inanimate object.
The sky was divided up into 88 different constellations in 1922. This included 48 ancient constellations listed by the Greek astronomer, Ptolemy, as well as 40 new constellations.

What Are The Benefits Of Natural Gas
What is natural gas?
Natural gas is a fossil energy source that formed deep beneath the earth's surface. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4). We use natural gas as fuel, electricity and to make materials and chemicals.
What are the benefits of natural gas?
1. Produces cleaner fossil fuels
Natural gas is one of the safest and cleanest fuels available. It emits less pollution than other fossil fuel sources. When natural gas is burned, it produces mostly carbon dioxide and water vapor; the same substances emitted when humans exhale. Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted; making natural gas the cleanest burning fossil fuel of all.
2. Produces 50% less carbon dioxide (CO2) than coal
Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant. Considering only tailpipe emissions, natural gas also emits 15 to 20 percent less heat-trapping gases than gasoline when burned in today’s typical vehicle.
