Interest vs Hobby: Are they synonyms?

While interacting with people, I came to a realization that for most Hobby and Interest are synonyms or at least interchangeable.

Almost everyone seem to talk about them in the same breath.

Here I have tried to dissect the two terms, bringing out the subtle differences for better understanding.

First let us read  the dictionary meaning of both terms
Interest:
·         The feeling of wanting to know or learn about something or someone or
·         The quality of exciting curiosity or holding the attention or
·         An activity or subject which one enjoys doing or studying 
Basically, an interest is something one likes to do or something that one has a feeling for.

Hobby:
·         An activity done regularly in one’s leisure time for pleasure
It is a spare-time recreational pursuit. It is an action, something one does. Usually, hobbies need devotion; it is something that has to be done systematically.

Interest has a broad scope which includes hobby. If one has an interest, they may or may not develop it into a hobby. If someone is somewhat interested in something, he may not pursue it actively.
For instance, most of us are interested in sky diving, but not many have done it even once or one may not play football but watch and read a lot about the sport as her interest lies in it.

It is also true that in order to pursue a hobby one has to be interested in it.  
"Hobby is an interest which has been pursued actively"

Breathtaking photos and videos tweeted from the ISS


Have you ever wondered how would the Earth look, if viewed from space? Will sunrise be any different from what we see here at the Earth?


It shouldn't be surprising to know that it takes a few mouse clicks to get live feeds from International Space Station (ISS) and telescopes from space. Click here to see live view from ISS.


We only have to scroll down our Twitter feeds over our morning coffee to see the curvature of the Earth, the structure of hurricanes from above and the blue tinge of our delicately thin atmosphere.

Here are some of the best tweets by astronauts on the International Space Station.

Undocking of the Cygnus Spacecraft

We should be thankful to the scientists and engineers for their countless hours of hardwork. It would have been, otherwise, impossible to showcase the Earth's beauty from a different perspective. Teaching us exactly how unique, isolated and fragile our home is - and how we shouldn't take it for granted.

Spotting the International Space Station!

The International Space Station (ISS) is the largest man-made object in space - and it’s visible to the naked eye!
As with many other things in the night sky, you don’t need a telescope or any special equipment to see the ISS. You only need your eyes and a clear sky.
Larger than a football pitch, the ISS orbits the Earth roughly 200 miles above the surface, speeding around our planet at 17500mph.
The ISS is a laboratory, orbital outpost and test platform for Mankind’s future in space as well as many other experiments. Spacecraft from Russia, America and Europe regularly visit the ISS bringing fresh supplies and ferry crew to and from the station. These tiny spacecraft can also be seen by the naked eye when flying near the ISS.
How to spot the ISS?
As the third brightest object in the sky the space station is easy to spot if you know when to look up. The space station looks like a fast-moving plane in the sky, bright enough that it can even be seen from the middle of a city!
You can find the India pass times and follow AstroHeads on Facebook for alerts, so you know when the ISS is passing over you.
When you get your sighting results from NASA - remember you need to look at the direction and elevation given to be sure to see them. Generally, the station and shuttle move from west to east across the sky.
Once you are good at spotting the station and shuttle you can try using binoculars. As the station expands in size - it is easier to spot and more details may become visible. Also if you are using binoculars you might see the shuttle dumping waste or supply water overboard. As the water is sprayed out it immediately changes into ice crystals, providing a spectacular sight glittering in sunlight.
ISS sighting  last from roughly 2-6 minutes.
The International Space Station can be enjoyed by anyone wherever you live you just need a cloudless sky. It’s a real thrill knowing there are people on it as it passes over.
Make sure you wave, they might wave back.

The legend of the Shooting Stars!

As the legend has it that "wishing upon a shooting star makes the wish come true"


Each of us at some point might have wished upon a shooting star. Ever wondered, "How this legend came into existence?"
Here is some interesting information that I have found about THE LEGEND!


It started somewhere between AD 127-151 with the Greek astronomer Ptolemy, "The Gods occasionally, out of curiosity, even boredom, peer down at the earth from between the spheres, and stars sometimes slip out of this gap, becoming visible as shooting or falling stars. Since the Gods are already looking at us at such a time, they tend to be more receptive to any wishes we make!"
It is also mentioned specifically that for the wish to be granted, "the wisher has to verbalize the wish either aloud or to one's own self, keeping the shooting star in vision."

Despite being a man of science, I like to do it sometimes. It's reassuring, though I don't actually believe that the falling star is a sign that I will have my wish granted to me. (It never has been yet - can't tell you what it is though, because it won't come true! *wink* )

Wishing upon a shooting star is simple RITUAL, "the wisher has to verbalize the wish either aloud or to one's own self, keeping the shooting star in vision."  Yet many have failed to do it correctly!

Foremost reason is the impulse to shout,"Shooting Star". One must overcome this impulse, "YOUR WISH" must come first.
That also means that you need to keep your wish handy, ALWAYS! You just have fraction of a second to verbalize it.
And the most common reason is not finding time to observe night sky. Remember Murphy’s law. The moment you look away from the sky, a shooting star will appear.

For the non-believers observing a shooting star is a fascinating experience, one that has always intrigued us since our childhood. One must not miss this beautiful phenomenon!

If "Shooting stars" ever excited you, Keep an eye MATE!
