GAURI'S BLOG : HOW ARE AURORAS FORMED?

Image
  How are northern lights formed? It was the 14 th of January 2022, the night every person present in Stockholm actually in the whole of northern Europe would remember. Bright dazzling green light shining up in the sky, like the beautiful sparkle in the dark sky, yes it was auroras. It was among the strongest auroras witnessed. We could even see dancing red auroras in the sky. It is a rare phenomenon that occurs once or twice a year. But how are the auroras formed? They are the result of the disturbance of the earth's magnetic field. Well! To Make it interesting look at the image below: When the sun gives out strong and hot solar flames(winds) they are so large that they reach earth and even move beyond it. These can cause severe harm to the people living on the earth, but there is a shield that protects us from these solar winds. This shield is nothing but our earth's magnetic field. This is what the earth's magnetic field looks like:   The hot solar flames trav...

  Is there other intelligent life in the universe? What if there is an alien sitting next to you, peeping in your phone and apparently smiling and waving at you? What would be your reaction? Well, some people might feel it horrifying but, I don’t. Jumping into the actual meaning of the term ‘ALIENS’ you would feel the same. ‘Any extraterrestrial living organism existing in the universe except Earth are called aliens’ as per the humans.   Well what we see in the films and video games, picturing ALIENS having 3 heads or 1 eye or exceptionally dwarf or gigantic or without skin and we can see veins going through it or some with superpowers, whatever, they are just fictional piece of work, by HUMANS.   We still don’t know how would they look like? But I would try to explain some terms that would help us to be prepared for this instance. When we define LIFE, we can say that, ‘life is an ordered system that keep itself going in spite of surviving challenges and can reproduce its...

  What if you got a ticket to travel in space? Why should we go to space? What is the justification for spending money and efforts just for getting few lumps of moon rock? Aren’t there better causes here on the earth? The obvious answer is, not leaving the planet earth would be just like wandering on a desert island, not trying to  escape . I think each human is unique, of course genetically but with skills too. On earth, we have enough doctors, architectures, software engineers businessmen and of course the colossal amount of population struggling on earth. But do I have to join them in the same race? Or I can do something  interplanetary ! Other than the stuff humans do on the earth. So I decided to change my motive and think beyond our gravitational pull.   Not exploring our solar system would be like the situation in Europe before 1492. Not letting  Columbus  go on a wild chase. Yet the new world found then, made a lot of difference today. Just think we...

  CAN GOD FIT IN SCIENTIFIC STORY OF CREATION? LIKE A “GOD PARTICLE”?? BASICALLY, THIS BLOG IS ABOUT THE SO-CALLED TERM “GOD PARTICLE”. BUT WHAT EXACTLY IS THE GOD PARTICLE? DOES IT EXIST AROUND US OR IS MADE BY SOMEONE?       WELL, GOD PARTICLE  IS ACTUALLY A “HIGGS BOSON PARTICLE”. IN FACT IT HAS NOTHING TO DO WITH THE TERM GOD. THEN WHY DO PEOPLE CALL IT AS GOD PARTICLE ? HENCE THE ANSWER IS A SILLY ONE. IN 1993 WHEN THE AMERICAN PHYSICIST LEON LEDERMAN WAS WRITING A BOOK ABOUT A HIGGS BOSON PARTICLE HE EXAGGERATED  IT AS “THE GOD DAMN PARTICLE” AS THIS PARTICLE IS ACTUALLY MIND-BLOWING AND SURPRISING TOO. BUT AN EDITOR AS WELL AS PUBLISHERS DIDN’T  LET HIM PUBLISH THIS “GOD DAMN” WORD SO HE CHANGED IT INTO A “GOD PARTICLE”. BUT IN FACT MANY SCIENTIST INCLUDING ‘PETER HIGGS’ HIMSELF, FROM WHOM THIS PARTICLE IS NAMED AFTER, DISLIKED THIS NAME. BUT I THINK IT'S NECESSARY TO KNOW THE EXACT REASON OF SOMETHING BEFORE YOU BELIEVE IN IT. SO I THOUGHT...

  HOW IT STARTED AT FIRST PLACE? We know we live in 3-dimensional space, there are other planets out there, many stars revolving, and billions of galaxies that we didn't even know yet. But from where did this huge universe come from? Did anyone make this? Then how we came into existence? Not asking this question is like not asking why and how do you exist in this world! If one believed that the universe has the beginning,  then what happened before the beginning?  What was God doing before the world was made?  Many people try to avoid it either by claiming that the universe didn't have the beginning or by maintaining that the origin of the universe did not lie within the realm of science but belonged to metaphysics or religion. In my opinion, this is not the position any literate person should be in. If you are not curious about everything you just don't think beyond the 9 to 5 job or a business and beyond the ozone layer. Let's try to understand the beginning of the...

    How the sun is born? Where does it get its light from? Well, imagine it’s a Sunday morning and you woke up just before your alarm. And suddenly you see no sunlight our there! Eventually, you realized that the sun of your solar system is dead.  How different your life would be now? How do ecosystems would react? but First of all, would you be able to survive? Ok ok, stop imagining! I know this would be a nightmare to face on a Sunday morning. But before that let’s dive back to the question, how is our sun born? If you read my previous blog, you are very well aware of the big bang. Here, just after few seconds of the big bang, the stars or sun begin to form (make sure that stars and sun are the same). Now to make the sun here are some ingredients we need! Ingredients:               1. Some Gases               2. Gravity               3. Time. In the in...

  The telescope that will work as a time machine! When we say telescope everyone has this only picture in the mind – But telescopes are not only used on the earth, but in space too. In fact, we get a more clear and effective view of space when it’s taken from a space telescope than any telescope on the earth. This is one of the telescopes situated on the earth's surface. On the earth, we have a dense atmosphere with various components and gases as well as polluted air which blocks the view of outer space. The other problem is light pollution.  Due to large cities and urban areas we have lots of bright light in the sky which makes celestial objects blur. So we didn’t get clear and exact images of the celestial object as it is. So, to solve this problem, many decades ago humans launched space telescopes that are orbiting the earth, outside its atmosphere. When we don’t have any light and air pollution we can easily get pictures of the stars and galaxies.       ...

  What would happen to your body when exposed into  the space???      You decided to take walk outside your spaceship and went without your spacesuit, imagine what would consequently happen to you? Option A: your blood will boil? Option B: your body would burst into pieces? Option 3: you will freeze into ice? Option 4:you would get burnt? Okay! Did you lock your answer? Let's dive into the scientific reasons behind this. First thing you are not surrounded by oxygen anymore. And hence your lungs will run out of air storage. In this case, if you tried to hold your breath just like we do in water, your lungs will explode due to the absence of outside atmospheric, just like a balloon. So letting your breath out would be a good idea to survive for a few more minutes. Your brain will turn off in 10 to 15 seconds due to lack of oxygen and will make you unconscious. Now you have only 30 seconds to 2minutes to wake up again if you get an external oxygen su...
