JOURNEY TOWARDS SPACE EXPLORATION

   Comets and meteors! All the shooting stars are so philosophical and romantic, we pray every time they fall. In the hope, may our wishes come true in life. | Fire from the sky | In earlier days, people feared meteorites for centuries. Some saw them as fiery dragons, others as weapons sent by some angry gods. But now we are way smarter than those people right? Let's take a tour of the understanding of these objects closely. In between the planets, space isn’t empty. there is gas, dust, rocks called asteroids, and even comets- which can be thought of as a small snowball. Some comets are so small you wouldn't see them. But some are even the size of an island. | Meteor | When pieces of comet burn up in the earth's atmosphere, they produce meteor showers, and bright shooting stars race across the night sky, as in this picture of Leonid meteors.  They are known as shooting stars too. This phenomenon takes place about 90km above the planet's surface. | Meteorites | If this m...

 A part of Sun🌞Broke Off!!! You must have recently heard that a part of Sun Broke Off. Astronomers saw a huge plasma filament erupt from the Sun, surprisingly pulling itself apart. And after getting detached, it furiously rotated till it reached the star's North pole, creating a terrifying vortex, just like a gigantic tornado. But how is it possible for a solar chunk to break apart??  What's the physics behind this intriguing event??  Does it mean a solar tsunami is on the way to hit our planet???  There are some critical questions and to answer them let's look at what happens in the Sun🌞. If you have my AURORA'S Blog you would understand the context of this topic more efficiently, here is the link..... HOW ARE AURORAS FORMED? Every eleven years, the sun's activity undergoes dramatic changes due to magnetic field reversal. The magnetic poles flip their position, meaning the north becomes south, and the south becomes north. This period of eleven years is known as ...

  What exactly is dark matter?  Our universe is made up of galaxies,stars, gases,planets, rocks, black holes, nebulae and many more celestial objects. And as we discussed earlier in the   BIG BANG BLOG  that our universe is expanding each day at a very high speed. This expansion has been started since our universe was born and it still goes on expanding in the dark empty space. In 1933, Fritz Zwick coined the term ‘dark matter’. When scientists wrote a mathematical equation about the universe, they found something that is still not known to humans, but most of the part is occupied by it. This entity was totally unknown but it was an important part of the universe to expand.(mathematically). In simple words, just consider A +B=C. Consider we know the value of a and c. but we don’t know what B is exactly. But if we remove B from the equation like this, A=C  then this won't make sense when the values are different. There must be something B to ...

 WHAT IS INTERNATIONAL SPACE STATION: A HOME FOR ASTRONAUTS! First of all happy 24th anniversary to the ISS. On this occasion my blog is dedicated to the powerful leap of humanity to make our significance in this darkness. An international partnership of five space agencies from 15 countries operates the International Space Station. The one we see the picture like these. To keep it simple this is a science laboratory in space and also a residential area for humans to stay too. The space station has been continuously occupied by humans since November 2000. An international crew of seven people lives and works while traveling at a speed of 8km per second, orbiting Earth about every 90 minutes. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets. So they have 16 GM’s and GN’s. (A big YAWNNNNN). The acre of solar panels that power the station means sometimes you can look up in the sky at dawn or dusk and see the spaceship flying over you...

    A Sneak Peak That Will Fundamentally Change the Way You Look At the Death of a Sun In my last blog, you got the idea about how the sun is actually born all by itself. Let's see how it ends? Before that, I want to introduce you to the cosmic scale. This will help you visualize more clearly. All our planets together form our solar system, many such solar systems together form the milky way(spiral shape), all milky ways and local groups together form small galaxy clusters(group), these small clusters together form Superclusters, at last, these superclusters together is what we call as OBSERVABLE UNIVERSE. Hush!!! Just imagine how huge this is. And then look back to your tiny human problems. Relatively it justs nothing to what's there outside beyond these clouds. Coming back! Our sun is made up of hydrogen and helium gases, right? For instance, let's take your vehicle. Monday morning you full your vehicle's fuel tank. Just like a normal day, you do your everyday chores ...

INDIA IS READY TO LAUNCH THE FIRST-EVER INDIAN ASTRONAUTS MISSION TO SPACE !! YES, YOU READ IT RIGHT. WE ALL HAVE HEARD ALL THE ASTRONAUTS GOING TO SPACE AND COMING BACK TO EARTH. MANY MISSIONS ARE SUCCESSFULLY COMPLETED BY NASA AND ROSCOSMOS (Russian space agency). ALSO, KALPANA CHAWLA AND MANY OTHER INDIAN-ORIGIN ASTRONAUTS HAVE VISITED SPACE BUT THROUGH FOREIGN SPACE AGENCIES.  BUT BUT BUT...  ISRO HAD FINALLY TARGETED ITS 'GAGANYAAN MISSION' WHICH WILL SEND HUMANS TO SPACE FROM INDIA WITH ALL GEARS UNDER THE CONTROL OF INDIA. TODAY WE WIL KNOW MORE ABOUT THIS MISSION THAT WE ALL MUST BE PROUD OF. QUICK INFO : GAGANYAAN MISSION WILL HAVE 2 UNMANNED FLIGHTS AND 1 MANNED FLIGHT. GAGANYAAN SYSTEM MODULE WILL HAVE AN ORBITAL OR CREW MODULE THAT WILL ORBIT AROUND THE EARTH IN LOW EARTH ORBIT AT THE HEIGHT  OF 300-400 KM. THIS MODULE WILL HAVE 3 HUMANS INCLUDING A WOMAN GOING AROUND THE EARTH FOR 5-7 DAYS. WITH THIS INDIA WILL BE IN THE RACE WITH THE USA, RUSSIA, AND CHINA. ...

                      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.                       ...
