S-400 ONE OF THE WORLD'S BEST AIR DEFENCE SYSTEM

One of the world’s best air defense system is “S-400”.


It is the extended version of “S-200” and “S-300”. These defense systems were developed in 1967 and 1978. These two systems still counted in best air defense system, due to this they are still in work.

America and Russia both are ravels of each other. Due to this both are engaged in developing air-crafts and army attires. But Russians air craft does not compete Americans fighter planes, due to this they decided to develop air defense system. And as a result Russia develops “S-200”, “S-300” and “S-400”.

“S-400” was developed in 2007. It not only detect missiles and air crafts in the range but also launch anti-missile when needed.
It is considered world’s best because of its specifications:

  • Multifunctional based system, in which missiles can be launched at different speed. It has four different missiles for short and long distance.
  1.      Long distance missiles, to destroy target in range of 400km. 
  2.   Second missile to destroy target in the range of 250 km.
  3.    Third is to target in range of 120 km.
  4.   And for the target in the short range 40km.

These missiles are used according to target range and speed.


  • And second specification of this system is it’s accuracy and detection speed. And this is possible because of their large number of ‘radars’.
  • And third one specification is its range. It can track supersonic and hypersonic missiles upto 600 km. And can destroy them latitudinal 30 km and longitudinally 400 km.

The one of the best thing in this system is its 12 launchers with the help of which it can destroy upto 36 target at once, by launching 3 missiles with each launcher.
It can also detect and destroy American 5th generation S-35 fighter plane.

China is the only country with which Russians shares this technology but now they are also interested to share it with INDIA.

Some air defense system:

ASTER”- Air defense system of France and Italy.
AERO MISSILE SYSTEM” –  Israel use this technology.
THAAD (TERMINAL HIGH ALTITUDE AREA DEFENCE)” – This is the technology that America uses.

What is Nebula. Images of some nebula by Hubble

A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries." How do stars form in a nebula? Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star. Some of the most amazing nebula pictured by Hubble in Milky Way Galaxy The Eagle Nebula’s Pillars of Creation (M 16, Messier 16) The dust and gas in the pi...

25 June 1975 BLACK DAY FOR INDIA (EMERGENCY)

25 June which is considered as black day for india. It was 25 June 1975 when Prime Minister Shri Indri Gandhi declared Emergency through radio in India. In India, "the Emergency" refers to a 21-month period from 1975 to 1977, Officially issued by President Fakhruddin Ali Ahmed under Article 352 of the Constitution, the Emergency was in effect from 25 June 1975 until its withdrawal on 21 March 1977. The order bestowed upon the Prime Minister the authority to rule by decree, allowing elections to be suspended and civil liberties to be curbed. For much of the Emergency, most of Gandhi's political opponents were imprisoned and the press was censored. Several other human rights violations were reported from the time, including a forced mass-sterilization campaign spearheaded by Sanjay Gandhi, the Prime Minister's son. RESION BEHIND EMERGENCY On 12 June 1975, Justice Jagmohanlal Sinha of the Allahabad High Court found the prime minister guilty on the charge of...

Collision of galaxies, images taken by hubble

The interaction between galaxies is an on going process in universe. However the merging of big galaxies with each other on average once over the past 9 billion years. But Small galaxies were coalescing with large galaxies more frequently. In fact, our own Milky Way galaxy had several such mergers with small galaxies in its recent past. In the combination of galaxies there is no collision of stars with eath other, it is the dust and other material which collapse and billions of stars are born, mostly in groups and clusters of stars. Some of the images of colliding galaxies taken by hubble This is image of a pair of interacting galaxies called Arp 273. The distorted shape of the larger of the two galaxies shows signs of tidal interactions with the smaller of the two. It is thought that the smaller galaxy has actually passed through the larger one. This nearly 300 million light years away from earth. And a part of Constellation "Andromeda" Hubble has captured a...
