stunning Stars

The sun is the most important star in our galaxy. It is the source of life on earth. Most of all ancient civilizations worshiped the sun as a god. In the same way there are also about 300 billion different stars in our galaxy. All of which contain different history, characteristics and general information. They each contain their own story of how they came about. Many of these stars are a part of a certain constellation and have been around for billions of years.

Polaris is one the best known stars. Polaris is not hard to miss in the sky; it is the 50th brightest star and does not disappear. The reason this star will not disappear is due to the fact that the Earth’s axis is aligned pointing towards Polaris in the same direction North faces but will eventually shift over time. In comparison to the sun, this star is 10,000 times brighter, 100 times larger and has 10 times more mass to our sun. Polaris has about the same temperature as the sun. 

Sirius also known as The Dog Star or Canicula was discovered in 1915. Sirius gets its name from the use in the Greek calendar. “The time of year when this star rose and set with the Sun was the hottest part of the summer, and was given the name Seirios, 'scorching', a name that was acquired by the star itself”.Sirius is the fifth closest star to the solar system”. It is only 8.6 light years from our solar system which makes this star the brightest star known. Sirius has a binary system which means that there are two stars revolving around each other. “Sirius A is a blue-white star 25.4 times bigger than the sun. Its surface temperature is twice as hot as the sun, over 20 times brighter, and it’s mass 2.32 times more.” Sirius B revolves around Sirius A. This star is the first white dwarf to be discovered. Its diameter is almost equal to that of the earths. “It has a mass is 98% that of the sun, making it extremely dense.”

Another famous star is Betelgeuse. This star gets its name from the Arabic meaning “Armpit of the Central one”. It is the tenth brightest star in our galaxy and the brightest star in Orion which is the constellation in which it lies in. This star shines an orange-red color, 7,500 times brighter than the sun. Its surface temperature is 6000F. Betelgeuse is one of the largest stars known with a diameter of 700 million miles. This star is 520 light years away and also has about five companion stars in its orbit which is rare for a Red Super Giant. “Red super giants are stars that are close to the end of their life”.  Betelgeuse has about ten years left till it ends in a supernova explosion.

VY Canis Majoris also known as VY CMa was discovered roughly around March 7, 1801, by a French astronomer Jerome Lalande. (universetoday) Throughout the 19th century it was believed that VY Canis Majoris was a single star until 1917, Guerin noticed a three nuclei (Robinson, IBVS 599) the red hypergiant is the largest star known in The Milky Way but also in the entire universe. “It has a diameter of about 3 billion kilometres. Its radius is about 1,800 to 2,100 times the radius of the Sun.”  VY Canis Majoris is about 40 times the mass of our sun. ” It has an average density of about 0.000005 to 0.000010 kg/cu.m. This is very less when compared to the density of water (1000 kg/cu.m).” This star is about 4,900 light years from the Earth.  This star is found in the constellation of Canis Major which lies in the southern part of the sky. The name in Latin means “the greater dog”. This star is one of the most luminous stars. “Its luminosity is about 450,000 times the luminosity of the sun.” It is believed that this star is extremely unstable, as huge amounts of it’s mass it being thrown off into the closest nebulae.

swimming bird

 Penguins are highly social, often breeding in large colonies. Some species forage cooperatively and may dive synchronously while foraging in small or large groups. Species that breed in large colonies often have elaborate visual and vocal displays. Vocalizations are characterized as loud, short brays, grunts or whistles, the type depending upon species, for instance, banded penguins (Spheniscus) are also known as 'jackass penguins' because of their braying, while the giant penguins of the genus Aptenodytes most often whistle. In colonial species in which chicks group together in a nursery (or crèche) recognition of mates and offspring seems based on individually distinguishable calls. Penguins have a number of characteristic physical features, such as their erect posture, stiff wings, and counter-shaded body coloring (dark backs and white fronts). Penguins are medium to large birds. The smallest (the Little Penguin) is typically 40 cm (16 inches) tall and a body mass of one kilogram, while the Emperor Penguin can reach 1.15 meters (43 inches) and attain a body mass of 22-37 kg.Depending upon the terrain, penguins on land will waddle along shorelines and ice, or hop from rock to rock, some species being more adept at one form of locomotion on land than another. When on ice or snow, penguins can move swiftly by tobogganing (sliding along on their belly and propelled by their wings and feet).  Underwater, penguins use their modified wings (or 'flippers') to propel themselves forward, and it is this underwater 'flying', combined with the solidity of their bones, that enables them to reach great depths. The Emperor penguin is an exceptional diver and can stay submerged for 18 minutes and dive as deep as 500 meters (1,640 ft). Swimming speeds average two to three knots (3.7km/hr), but may reach 15-20 knots (27.8-37km/hr) for short distances. Swimming often includes porpoising (repeatedly breaking the water's surface with enough momentum to lift the bird into the air for about one meter), which may be carried out for reasons of speed, escaping predators or even purely to aid breathing (and possibly a combination of these factors).

Handy ultrasound machine

ultrasound which is also commonly known as a Sonogram. The definition of ultrasound is energy that is generated by sound waves of 20,000 or greater vibrations per second. Ultrasound is used in many different arrays. It is most often used in the medical field. Ultrasound uses sound waves that are too high to be heard by the human ear. A part of the ultrasound machine called the transducer is placed on the body part and sound waves are emitted from the transducer and reflected back from organs and tissues. When the wave is sent back to the transducer it puts it into the computer which then measures the length of time it took for the wave to leave and come back and this is what makes up the pictures.

The LUNA RING

Architectural/engineering firm Shimizu has proposed a Moon-based solar power plant to solve our energy and climate crisis here on Earth. And also Japan, which was hurt by the devastating Fukushima meltdown in 2011, is actively seeking out alternative power resources to wean itself off nuclear energy. So, Shimizu wants to build a giant strip of solar panels 248 miles wide all the way around the Moon’s equator. Then, they’d send the energy back to Earth in the form of microwaves, which we’d convert into carbon-free energy at stations on the ground. Proposed for operation as early as 2035. Since, the moon has no atmosphere; the cells would be continuously harnessing solar power. Shimizu have also proposed pyramid cities and a space hotel, so the Luna Ring might not be the wildest thing in their minds. Given that California has already signed a contract to buy electricity from Solaren’s Earth-orbiting power plant, a Moon unit can’t be that far behind.

Green energy

The Shimizu Corporation, Japan what it is planning to build a solar power plant on the moon, Called the LUNA RING, the project will harness sun's power and beam it to the earth.The firm planning this incredible feat, plans to place solar cells near the moon's equator. The belt of cells will be about 400 kilometers (248 miles) and will soak-up the sun's energy and direct it to earth in the form of microwaves and lasers."Virtually inexhaustible, nonpolluting solar energy is the ultimate source of green energy that brings prosperity to nature as well as our lives," the company said.

Constructing a Solar Power Grid on Moon

The firm wants to employ an army of robots to help build the solar grid. Shimizu will use lunar resources to construct the Solar Belt, which will stretch to about 11,000km in length (6835 miles). Machines and equipment will be manufactured on earth and sent to moon for installation. A team of astronauts will manage robotic surface operations. "Water can be produced by reducing lunar soil with hydrogen that is imported from the Earth. Cementing material can also be extracted from lunar resources. These materials will be mixed with lunar soil and gravel to make concrete. Bricks, glass fibers and other structural materials can also be produced by solar-heat treatments," the company also said. As our atmosphere is virtually transparent to microwaves and lasers, Shimizu envisages solar energy being fed through microwave/laser transmitters located around the Earth-facing side of the moon. As the moon orbits the Earth and the Earth rotates, international receiving stations will feed electricity grids with plentiful lunar solar power as the moon rises to when it sets.
