Why the Recent Asteroid Impact news can't be Ignored?


Asteroid, small bodies that wander the infinite space.
Well the recent news of a big asteroid that was on near collision with the earth is a big surprise.
And why this news cannot be ignored!

First of all the discovery time of asteroid was too short.

  • The asteroid was spotted just 4 days before it crossed its nearest earth point!!
  • Secondly due to such a short notice the size was estimation was wrong and the asteroid was twice as large!! 

In order to prevent a asteroid from colliding with earth we should have early knowledge and probably years before collision to prepare an impact avoidance strategy. 

Had this asteroid collided with earth a large amount of human race would have been wiped out and earth atmosphere would have been affected so bad that nothing would thrive for at least next 100 years

Asteroid are know to have caused mass extinctions on earth.

After the impact takes place large amount dust will spread in to atmosphere which will reduce the amount of sunlight reaching earth. this will result in a cold atmosphere on earth known as impact winter causing
massive damage to both biosphere and humans alike.


When a impact with earth occurs , the amount of damage depends upon the size as well as the speed of the asteroid.
So comets which have high speed can cause more damage than a relatively bigger asteroid.

The most devastation extinction was caused by the asteroid at Chicxulub in Mexico that was 10km in diameter and caused a impact crater of 180 km diameter and is thought to be the main reason for dinosaur extinction. 

One of the best know recent event of asteroid impact is the Tunguska event in Russia in 1908. In this event a large asteroid burst just 6-9 km above earth surface causing the wiping of a thousand of km of forest and if it had occurred over a city it would have destroyed the entire city.

Although this time we have been saved next time we wont be so lucky, so we should devise a strategy and be completley ready to avoid a human extinction event.

China, The Future Space Leader?


Space is a entity that every country dreams to capture. Majority of them do it for military purposes. Launching Military satellites and communications satellite becomes the first step and then comes near space and further space missions

Currently only USA can be considered as a Space power having developed its space technology a lot and only one to send man on moon. Although NASA ambition may be marred by recent cuts to it and no space shuttle to fly currently , but it has included private players to cope with it.{See : SpaceX}

China the new economic power seems to also bear the ambitious of becoming a major space power. China had done an unmanned space docking recently which was a major success to its ambition of making its own space station and becoming a more sophisticated player in space race

China few days back launched its first women into orbit making it a monumental event for the country. This is  a big achievement for China National Space Administration (CNSA). Liu Wang  along with two other astronaut has been included in the Shenzhou-9 which is a

Explore The Current Position of All Planets in our Solar System (EXTREMELY AWESOME)


If you are really interested to find out the current location of all planets of our solar system and would also like to know which part of them is currently illuminated and which is in dark then Solar System Scope  is the site for you.
The site offers you the realtime location of all planets. When you visit the site you are greeted by a beautiful music. A control panel is provided to explore the solar system.

http://www.solarsystemscope.com/ by SUNAEON
On the left of the screen you have controls to set the view.
There are 3 differents view
1.Heliocentric View
2.Geocentric View
3.Panoramatic view.
Left control panel also provides many other settings
At the bottom you have the time pane which allows you to observer the solar system at various points of time.
And on the right you can set the camera zooming options
http://www.solarsystemscope.com/ is truly a great site to visit.
