What is Astronomy ?

In simple definition,

Astronomy is the Study of Universe beyond the Earth's atmosphere. Rather through the use of Astronomy explains the evolution of the universe and through sound mathematical simulations forecasts its development.

Although Astronomy has been there in for thousands of years and which is perhaps the oldest science known,but it is only in the last century and most probably particularly the last few decades that we the human have developed the technology to study the universe in greater detail and found lot more.

Every day we are gathering lot of new data's on everything from galaxy formation to the black holes to the big bang itself using high end array of multi-wavelength telescopes on the ground and also in space (for example HUBBLE telescope).

In next post, we'll learn about What is an Astronomer , Astronomical Telescope, and Facts on Astronomy on Space Science Facts

Difference Between Astronomy and Astrophysics :

You should know that both term is different from each other in great extent,because
Astrophysics
Astronomy is the study of outer space in which the planets, the moons, the sun and other stars, galaxies,asteroids,comets etc. all fall under astronomy.

We should not be confused Astrophyiscs with astronomy,
Astrophysics is the study of the physics or composition of celestial bodies.

Basically, it covers gas, matter, energy, light that comprises of planets, stars, galaxies, etc.

10 Ways To Keep Our Planet Earth Green from Affects of Global Warming

By // No comments:
The most hypertension ever falling buzz is that the effects of Global Warming we are facing now. It's not about how global warming occur because we know the fact Who is responsible for global warming .

Now, the biggest problem is not to debate about it but to find a solution for the question  " How to reduce global warming ? " or simply How to keep our planet green .

Global Warming,earth


Global Warming :

You might know Global warming is the major cause for increase in earth’s temperature in the atmosphere, which results in melting of glaciers causing rise in sea level. 

The sun’s energy heats up the earth and causes changes in the weather and climate to occur.These changes which is the effects of the warming can both harmful to the environment and the life of humans to survive.

How to Avoid this ?

The more we put ourself with responsibility for our planet earth, we too can be a part of reducing the global warming extensively.

The more rich you're, the best you can do good thing" 

People living in developing nations / poor country may have wish to do their part but their financial and economical conditions may prevent to do so.

The Ten Possible ways that we can follow to reduce global warming and save ourself from the hipe.
reduce,global warming

1.Use CFL lamp:
       
Its better to get started by replacing a regular incandescent light bulb with a compact fluorescent light bulb (cfl) because CFLs use 60% less energy than a regular bulb. This simple switch will save about 300 pounds of carbon  dioxide a year. 

 *You don't really need to have ALL the lights on ALL night .
 *Save Energy as much we can..

2.Don't Fly - flying is the one usually unnecessary thing we do that can have the biggest immediate effect on greenhouse gas emissions (CO2). Long-haul flights are the worst as they have to carry extra fuel that in the early part of the journey that is needed to burn to carry the extra fuel that is needed in the later parts of the journey .

Flyin over Long Distance flights can produce about the same amount of CO2 caused by

* 15,000 miles (18 months worth) of motoring in an average size standard car
* 1 return long-haul flight e.g. India to Australia, South America or the Far East
* 3 return medium-haul flights e.g. Europe to East Coast America, Africa or India
* 6 return short-haul flights e.g. UK to Europe


3.Pick Up a More Economical Car.

We can probably reduce CO2 emissions by at least a one third by picking up a more fuel efficient vehicle.
Going in Hybrid Car: Toyota Prius is the first commercially available hybrid and least polluting production car currently available

Now, we've TESLA - all electric car which saves energy .

4.Protect and conserve forest worldwide
Forests play a critical role in global warming: they store carbon. When forests are burned or cut down, their stored carbon is released into the atmosphere - deforestation now accounts for about 20% of carbon dioxide emissions each year. Conservation International has more information on saving forests from global warming.

5.Eat less meat
I know its little tough task ,but try adopting it because Methane is the second most significant greenhouse gas and cows are one of the greatest methane emitters. They consumes grasses and multiple stomachs cause them to produce methane, which they exhale with every breath.

6.Cover your pots while cooking
Doing so can save a lot of the energy needed for preparing the dish. Even better are pressure cookers and steamers: they can save around 70%!

7.Take a shower instead of a bath
A shower takes up to four times less energy than a bath. To maximize the energy saving, avoid power showers and use low-flow showerheads, which are cheap and provide the same comfort.

8.Avoid Bottled Water


our tap water is more than clean enough to drink, but somehow we started to fall to go out and buy drinking water in bottles instead of just getting it from the tap.

You must know, Getting it from the tap and you will prevent the huge amount of fossil fuels consumed in transporting bottles of water to and from the supermarket, millions of tonnes of water unnecessarily transported over millions of road-miles. You will also help to avoid all those billions of plastic bottles needed.

Use tap water and yep u can use water filter to keep cleaner.

9.Organic Wastes
Around 3% of the greenhouse gas emissions through the methane is released by decomposing bio-degradable waste. We can help eliminate this problem by recycling organic wastes or if you have a garden compost in in it in a proper way.


10.Recycling
It's becoming easier and easier to do this as recycling facilities become more widespread reducing the need to throw things away to landfill.
Recycling,Global Warming
* Aluminium cans
*Glass bottles
*Newspapers
*Unwanted reasonable quality clothing and other goods to charity (it might be a must need for them) etc.

Or you can sell your stuff at Ebay or give away to free cycle

Sharing it with your friends can be a good start !

Micro Flying Robots Can Fly More Effectively Than Flies

robot,flying robo,insect

Engineers have long been working on in their attempts to fabricate micro aerial robots that can able to match the amazing flight capabilities of nature’s most advanced flying insects ¾ flies. 

Such robot flies,if they could be made effective enough means that could be used for a various useful tasks, from spying, to mine detection to search and rescue missions in collapsed buildings.

The scientists had tested this with many experiments to know how much energy it consumes..?

Watch Video :



Based on the results they have found that, during lift of it took little more strain (low speed) and while it flies i ts design of the blade like what a helicopter have,make it move faster and consumes only 50% power.

It made engineers to develop further that can revolutionise the Micro-Robot Technology

Update : There are even more variants of Micro Flying Robots available today , with increase in the innovation , research , development , it is made possible .

You might also seen such Micro Robots being used in Hollywood Movie such as G.I JOE RETALIATION .
