THE LOCAL GALAXY (2009) The composite images of the central region of our galaxy contains a supermassive black hole, now named Sagitarius A, around which our entire galaxy rotates. Its centre shows an area of extreme density, energy and activity thyat, combined with the gravitational effects of dark matter, holds enough mass to keep the galaxy from flinging iself apart. In November of 2009, NASA combined near-infrared, infrared and X-ray observations from their Hubble, Spitzer, and Chandra telescopes to bring this vewi of unprecedented depth. The yellow arcs show near-infrared wavelengths and highlight regions of star birth, the pinkish-red corresponds to infrared wavelengths illuminating dust clouds around these starbirth regions and the blue-violet hues x-ray wavelngths from activity such as stellar explosions and material ejected from teh black hole. The exact galactic centre in the white glow to the lower right of the middle of the image. The turquoise region on the left can be ascribed to a double star system, which may contain a body such as a neutron star or black hole. The volume of gas and dust between Earth and the galactic centre made it impossible to view this revgion before recent technological developments. Studying the galactic centre in such detail gives us clues into galaxy formation.

President Dwight D. Eisenhower established NASA in 1958[9] with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29, 1958, disestablishing NASA’s predecessor, the National Advisory Committee for Aeronautics (NACA). The new agency became operational on October 1, 1958.[10][11] Since that time, most U.S. space exploration efforts have been led by NASA, including the Apollo Moon landing missions, the Skylab space station, and later the Space Shuttle. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program (LSP) which provides oversight of launch operations and countdown management for unmanned NASA launches.

NASA science is focused on better understanding Earth through the Earth Observing System,[12] advancing heliophysics through the efforts of the Science Mission Directorate’s Heliophysics Research Program,[13] exploring bodies throughout the Solar System with advanced robotic spacecraft missions such as New Horizons,[14] and researching astrophysics topics, such as the Big , through the Great Observatories and associated programs.[15] NASA shares data with various national and international organizations such as from the Greenhouse Gases Observing Satellite.

From 1946, the National Advisory Committee for Aeronautics (NACA) had been experimenting with rocket planes such as the supersonic Bell X-1.[16] In the early 1950s, there was challenge to launch an artificial satellite for the International Geophysical Year (1957–58). An effort for this was the American Project Vanguard. After the Soviet launch of the world’s first artificial satellite (Sputnik 1) on October 4, 1957, the attention of the United States turned toward its own fledgling space efforts. The US Congress, alarmed by the perceived threat to national security and technological leadership (known as the “Sputnik crisis”), urged immediate and swift action; President Dwight D. Eisenhower and his advisers counseled more deliberate measures. On January 12, 1958, NACA organized a “Special Committee on Space Technology”, headed by Guyford Stever.[11] On January 14, 1958, NACA Director Hugh Dryden published “A National Research Program for Space Technology” stating:[17]

It is of great urgency and importance to our country both from consideration of our prestige as a nation as well as military necessity that this challenge [Sputnik] be met by an energetic program of research and development for the conquest of space… It is accordingly proposed that the scientific research be the responsibility of a national civilian agency… NACA is capable, by rapid extension and expansion of its effort, of providing leadership in space technology.[17]

While this new federal agency would conduct all non-military space activity, the Advanced Research Projects Agency (ARPA) was created in February 1958 to develop space technology for military application.[18]

On July 29, 1958, Eisenhower signed the National Aeronautics and Space Act, establishing NASA. When it began operations on October 1, 1958, NASA absorbed the 43-year-old NACA intact; its 8,000 employees, an annual budget of US$100 million, three major research laboratories (Langley Aeronautical Laboratory, Ames Aeronautical Laboratory, and Lewis Flight Propulsion Laboratory) and two small test facilities.[19] A NASA seal was approved by President Eisenhower in 1959.[20] Elements of the Army Ballistic Missile Agency and the United States Naval Research Laboratory were incorporated into NASA. A significant contributor to NASA’s entry into the Space Race with the Soviet Union was the technology from the German rocket program led by Wernher von Braun, who was now working for the Army Ballistic Missile Agency (ABMA), which in turn incorporated the technology of American scientist Robert Goddard’s earlier works.[21] Earlier research efforts within the US Air Force[19] and many of ARPA’s early space programs were also transferred to NASA.[22] In December 1958, NASA gained control of the Jet Propulsion Laboratory, a contractor facility operated by the California Institute of Technology.[19]

Advertising is a means of communication with the users of a product or service. Advertisements are messages paid for by those who send them and are intended to inform or influence people who receive them, as defined by the Advertising Association of the UK.

Description: Advertising is always present, though people may not be aware of it. In today’s world, advertising uses every possible media to get its message through. It does this via television, print (newspapers, magazines, journals etc), radio, press, internet, direct selling, hoardings, mailers, contests, sponsorships, posters, clothes, events, colours, sounds, visuals and even people (endorsements).

The advertising industry is made of companies that advertise, agencies that create the advertisements, media that carries the ads, and a host of people like copy editors, visualizers, brand managers, researchers, creative heads and designers who take it the last mile to the customer or receiver. A company that needs to advertise itself and/or its products hires an advertising agency. The company briefs the agency on the brand, its imagery, the ideals and values behind it, the target segments and so on. The agencies convert the ideas and concepts to create the visuals, text, layouts and themes to communicate with the user. After approval from the client, the ads go on air, as per the bookings done by the agency’s media buying unit.



An earthquake is a  sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth’s crust or volcanic action.A earthquake also occurs when two TECTONIC PLATES dash or bump each other the result which we get is earthquake.Earthquakes are of two types-major or lager earthquakes and -minor or small earthquakes..


Major or Lager earthquakes means their intensity is very high.If they occur we will not feel the tremor but we can say that it was an huge and thrilling earthquake.Here are some images of major or lager earthquakes.


Minor or smaller earthquakes when occurs are very low. They are not felt by us so much. They are tremors and as compare to major or lager they don’t harm us much.
