JOURNEY TOWARDS SPACE EXPLORATION

                      DOES A BLACK HOLE HAVE SOUND? RECENTLY IN AUGUST 2022, NASA DISCOVERED THE SOUND OF A BLACK HOLE. YES, YOU HEARD IT RIGHT. BUT WE ALL KNOW THAT SPACE IS A VACUUM, THEN HOW COULD SOUND TRAVEL THROUGH IT? WHERE THERE IS NO MEDIUM, THERE’S NO SOUND! BUT THE GALAXIES WHICH HAS LOTS OF STUFF HAPPENING INSIDE THEM LIKE FORMING OF STARS, THE DYING OF STARS, AND THE CLASHING OF TWO STARS. THESE HUGE EVENTS DO PRODUCE PRESSURE WAVES IN THE SPACE. THE BLACK HOLE AT THE CENTRE OF THE 'PERSEUS GALAXY 'CLUSTER HAS GIVEN US THE FIRST SOUND OF ANY BLACK HOLE UNTIL NOW. THE OFFICIAL LINK TO THE SOUND IS ATTACHED BELOW AT THE END OF THE BLOG. WITH THIS PRESSURE WHEN CONVERTED INTO AUDIBLE SOUND WAVES, WE CAN HEAR THE SOUND IN THE SPACE. WELL, THIS WORK IS DONE BY NASA. THIS PROCESS IS CALLED 'SONIFICATION'. IT IS JUST LIKE TRANSLATING THE SOUND.                               THE DATA FROMCHANDRA X-ray   OBSERVATORY IS MERGED AND WITH LOTS OF COMPUTER WORK I

                         What are these JWST images going viral around?  Why are those particular for humanity? Well, this blog is going to be different. I would add all the information I have and make a small and sweet collection of new facts, so everyone can quickly go through this.  There are 5 images released by NASA that were captured by the JWST. FIRST IMAGE HERE WE GO                                          These took my heart at the moment I saw them. This is CARINA NEBULA. We can see some beautiful stars shining among a lot of gases.  WHAT IS A NEBULA?  A nebula or nebulae is a cluster of gas spreading in a random pattern in space around a star . WHEN IS IT FORMED?  A nebula is formed when a star is dying or when a star is taking birth. WHAT ARE THE Colors IN THE IMAGE TELL US?  The colors tell us the composition of matter. To make it simple every gas has different colors, hydrogen, oxygen, helium, and nitrogen they all have different clouds. Like sulfur is RED, hydrogen i

 ARE THERE SHORTCUTS IN THE SPACE TO GO THROUGH GALAXIES IN LESS TIME?  Well, we have always talked about space travel, going to other habitable planets, and more stuff about wandering in a quiet universe. But the question is how? by a rocket or a tesla?  Maybe we need a lot of fuel for it and also a lot of speed. NASA's rocket flies at the speed of 26,000 kilometers per hour. and the fastest is 163km per second. While the speed of light is 300,000 km per sec. Scientist says that we have to achieve greater speed than light to reach the other galaxies. And If we traveled with the spacecraft that we have today, it would take us 100 years to get to the nearest galaxy, like you literally have to spend your whole life in space travel. this ain't a good option. DO YOU KNOW WHAT IS EVEN EASIER?   A wormhole; is a magical gateway that connects two points in space and time with one another.  like a tunnel or something or a teleport hole to the other universe. the good news is, that scie

 Why do Elon Musk, Richard Branson, and Jeff Bezos spend millions on space travel? Is it really worth it? Hearing about space tourism, your reaction might be the same, but these crazy people have already started their businesses. SpaceX is a private space company owned by Elon musk, it has achieved many milestone jobs in recent years. Their aim is to create a reusable rocket with the minimum usage of fuel. Richard Branson is currently working on space travel tourism in his company virgin galactic. Blue Origin is a company owned by Jeff Bezos. Well, you must be thinking that why are these people even thinking of tourism when most of the people cannot be able to pay for it but you are wrong, these people actually plan the different strategies and think on the other level. Unfortunately, their targeted passengers are not you, like a common person or even an average rich man, Nope they aim for the top billionaires in the world, now you might say, there aren't many billionaires out ther

  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 itself’. A living

  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 wouldn’t have had  McDonald’

  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 THIS TOPIC SHOULD BE EXPRESSED. SO

  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 un
