WHAT IS SUPERNOVA ?? INTRODUCTION supernova is an very big explosion of star.it is a very big explosion take place in a space. credit : NASA  CAUSES a supernova happens when a change in core or center of a star is occur.a change can occur in two ways, but end of this way is same. TYPE I SUPERNOVA this type of supernova have a absorption line.this line is show that a star do not have any more hydrogen in them.this type of supernova are very bright in sort time.this type of supernova happens when a white dwarf is orbiting a big star. TYPE II SUPERNOVA the absorption line of supernova show that they do have hydrogen in them.a star must have at least 8 times the mass of the sun and no more than 45 times of mass of the sun to undergo this explosion. Supernova: Five Stages in the Death of a Star 1. Just before explosion  A red super-giant star  approaches the end of its  life. There is no more fuel  to burn and make it shine.  Soo...

KUIPER BELT INTRODUCTION kuiper belt is an area of ou r solar system t hat is e stim ated to stretch across 20 AU of space.it is contains s mall asteroid and some big asteroid size of Pluto.this things made mostl y of ice and other g ases such as ammonia,nitrogen ,m eth ane and water. the kuiper belt ext ends from rough ly the orb it of neptu ne at 30AU to 55AU from sun.the main objects o f th is belt covers much of this r egion .   FAC TS ABOUT THE KUIPER BELT 1. there cou ld be more than a trillion comet nucl ei in the main body of the kuiper belt. 2.the largest kuiper belt family members are pluto, makemake , haumen, lxion, quaoar etc. 3.the ices in the kuiper be lt data back to the formation of sol ar system .   There have been more than a thousand objects discovered in the Kuiper Belt, and it’s theorized that there are as many as 100,000 objects larger than 100 km in diameter. Given to their small size and extreme distance from Earth, the che...

NEUTRON STAR..           Neutron star are create when large stars finished all of fuel and collapse.if you want neutron star, size of the star that's greater than 1.5 sun masses and less than 5 times the mass of the sun.          if the star size is more than 5 times the mass of sun,star will and up as a black hole.but if the star is right in between those masses, it became neutron star.     if the star size is less than 1.5 solar masses,than the star don't have enough material and gravity to compress the object down enough. you only get the white dwarf. this is what will happen to our own sun one day.          the neutron star is formed when the star runs out of own fuel and collapses inward on itself. the protons and electrons of atoms are forced together into neutron star.since the star still has a lot of gravity, any additional material falling into the neutron star is super acce...

OUR CLOSEST GALAXY ANDROMEDA..                 Andromeda  is the largest galaxy in the Local Group, which includes the Milky Way, the Triangulum Galaxy, and dozens of smaller dwarf and irregular galaxies. A recent estimate gave Andromeda 700 billion solar masses. Our Milky Way is only 80% the mass of Andromeda. IMAGE BY :  jpl.nasa.gov                  The Andromeda galaxy was first observed by Persian astronomers, thousands of years ago, and was later cataloged by Charles Messier in 1764. He classified it as M31. In 1912, astronomers calculated its speed to be 300 kilometers per second, moving towards the Sun. Edwin Hubble first calculated the distance to Andromeda, by detecting Cepheid variables in the galaxy. He measured that it was 450 kpc, or 2.5 million light-years away; well outside the Milky Way galaxy.                Rec...

IS TIME TRAVEL POSSIBLE ?? IN TO THE FUTURE...         We cannot avoid moving into our futures, but we  can  control the rate that we move through time. This is a consequence of another lesson from relativity: Not all clocks are the same.  The speed at which you move through space determines the speed at which you move through time. In the succinct phrase: Moving clocks run slow. IF you could build a big enough rocket (don't ask me how, that's an engineering problem) to provide a constant acceleration of 1g (9.8 meters per second per second; the same acceleration as provided by the Earth's gravity at its surface), you could reach the centre of the Milky Way galaxy — a healthy 20,000 light-years away — in just a couple decades of your personal time. You could stop for a few hours, have a picnic near Sagittarius A* (the black hole at the centre of the galaxy), and then hop back into your rocket and come back to Earth. By th...

HOW ATM WORKS WHAT IS ATM?           An ATM is simply a data terminal with two input and four output devices. Like any other data terminal, the ATM has to connect to, and communicate through, a host processor. The host processor is connected to an Internet Service Provider in that it is the gateway through which all the various ATM networks become available to the cardholder (the person wanting the cash).            Most host processors can support either leased line or dial-up machines. Leased line machines connect directly to the host processor through a four-wire, point-to-point, dedicated telephone line. Dial-up ATMs connect to the host processor through a normal phone line using a modem and a toll free number, or through an Internet Service Provider using a local access number via a modem.           Leased line ATMs are preferred for very high volume locations because of thei...

ALAN TURING        Turing was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence.           he was a British scientist and a pioneer in computer science. During World War II, he developed a machine that helped break the German Enigma code. He also laid the groundwork for modern computing and theorised about artificial intelligence.             Born on June 23, 1912, Turing was part of an upper-middle-class British family involved in colonial India. Science was a passion for young Turing, who often took part in primitive chemistry experiments. Before applying to...

WHAT IS ARDUINO ? Arduino  is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers  and  microcontroller  kits for building digital devices and interactive objects that can sense and control objects in the physical world.  "Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform; for a comparison with previous versions, see the index of Arduino boards.
