Don't miss to watch the 'Transit of Venus'

Be prepared to watch a heavenly drama on 6 June 2012.
The Venus can be seen as a black dot travelling across the Solar Disk.

Here is my Simulation:

Yes, it is the "Transit of Venus across the Sun"

Key phases during a transit of a planet across the face of the Sun are often referred to as 1st, 2nd, 3rd and 4th contact. Credit: Michael Zeiler,

India comes under the visibility of the event after Sunrise.

See the graphic below:
Thiruvananthapuram can view it right from sunrise to 10:22 AM.

The graphic was prepared using the tool provided in 
You can change the location and see about your visibility to the drama.

Also read the following blog for wonderful information and graphics.       (nice and informative blog by ESA)    (Transit maps)

You can also find how to watch the event....
Follow safe way.... take care of eyes......

Enjoy the phenomena......
otherwise you will have to wait till....2017 Dec 11.

Controlling Climate Change - Geo-Engineering

There are many proposals to reduce the climatic impact and change because of the Global Warming.
Some of them tries to address the causative mechanism while some treats symptoms.....

Geo-Engineering is deliberate large-scale engineering and manipulation of the planetary environment to combat or counteract man made changes in atmosphere.

Have a look at the three proposals to reduce increasing temperature.

Modelling getting better .....

Clouds and aerosol particles have bedevilled climate modellers for decades. Now researchers are starting to gain the upper hand.
Researchers say they are beginning to turn a corner in simulating clouds and aerosols. In recent months, climate scientists have started rolling out initial results from the newest generation of models, which represent atmospheric chemistry and microphysics in much more sophisticated ways than previous incarnations. These models allow clouds and aerosols to evolve as they interact with each other and respond to factors such as temperature, relative humidity and air currents.
