Save Tiger!

As we all know that tigers are being killed at a very fast rate so we need to protect them. As already discussed in my first blog that why are they killed? i will tell you the steps that are being taken to protect them.
WORLD BANK & CII JOINS HAND TO PROTECT TIGERS
After viewing about the condition of tigers today the World Bank and the Confederation of Indian Industry (CII) have join hands to establish 'Indian Wildlife Business Council' (IWBC) that would promote that would promote the conversation of endangered species.
After signing the Memorandum of understanding in this regard with the CII's Deputy Director ,General Indrani Kar in Washington on June 27, 2012 , the World Bank President , Robert Zeollick said that the proposed council would lead the efforts to save tiger from becoming extinct.
The main aim of the IWBC is to promote tigers and biodiversity conservation for sustainable development.
The International Bank for Reconstruction and Development , International Development association , International Finance Corporation which comprises of World Bank Group will support IWBC.
Tiger population has decreased massively due to rapid industrialisation .poaching and illegal trade. There are hardly 3000 tigers left with us on this planet hope that this will help tigers to survive and there will be an inrease in the population of tiger.

Electric Motor

In our house we have so many devices which contain motors such as washing machines , coolers , hair driers , kitchen appliances, and many more but have you ever thought that how does an electric motor work?
Electric motor converts electric energy into movement. You must have seen a magnet inside an electric motor  if not then i think you should open an old motor and you must have a look of its components inside. What happens is that when an electric current passes along a wire in the field of a magnet, it exerts a force to move  the wire . Usually the magnet is still , while the coil carrying the current spins inside it .Domestic motors run on a.c . or alternating currents , and the current in the coil is rapidly reversed so the magnet's  poles change direction , forcing the coil to make another half turn . This process is repeated very rapidly as the motor turns .
When a motor runs form a d.c. or direct current , it flows in only one direction , a device called a commutator reverses the current and causes the coil to rotate .
So now i hope that you must have come to know that how does an electric motor work.

Galaxy Facts

Galaxies are group of billion stars that are held together by the force of gravity. Most of the galaxy in the universe are either spiral or elliptical , but some are irregular in shape.
THE MILKY WAY GALAXY
 Milky Way galaxy

The best known galaxy is the Milky Way galaxy .The word 'Galaxy' comes from the Greek word for milk this is so because before the telescopes were invented or where powerful enough to prove that they were made up of individual stars , galaxies looked like milky or cloudy areas in the sky.Milky Way galaxy is our galaxy in which we and our earth exists. Our galaxy is one of 100-200 billion stars in the milky way galaxy ,which is 100000 light years in diameter. The sun and all the planets take about 200000000 years to complete its one orbit around its center.
 Magellanic Cloud
BRIGHTEST GALAXY
The large Magellanic Cloud which is visible only in the southern hemisphere ,is 1700000 light years form Earth and 39000 light years in diameter.
LARGEST GALAXY
The Central Galaxy of the Abell 2029 galaxy cluster was discovered in 1990. It is 1070 million light years away and has a diameter of about 5.6 million light years , 80 times the diameter of our Milky Way galaxy.
It has a total light output equivalent to 2 trillion times that of the sun.
NEAREST GALAXY 
The Sagittarius Dwarf which was discovered in 1994,is more than 70000  light years from Earth ,and is being torn apart. It is the nearest galaxy to us.
MOST DISTANT GALAXY
In 2004 astronomers at the European Southern Observatory ,Chile, announced the discovery of Galaxy Abell 135IR1916. It is about 13.2 billion light years away from Earth.
REMOTEST VISIBLE OBJECT
The most distant thing that can be seen in the universe from the naked eye is the
Andromeda Galaxy 
Andromeda Galaxy which is 2309000 light years away from Earth. This galaxy has 300 billion stars and a diameter of  180000 light years. The light we see now from  Andromeda Galaxy left there just after the first humans appear on earth.
