GAURI's BLOG : INTERNATIONAL SPACE STATION.

Image
 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 your ho

GAURI's BLOG : DEATH OF STAR

    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

GAURI'S BLOG : 'MISSION GAGANYAAN' BY 'ISRO'

Image
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. THE SP

What is the sound of black hole?

Image
                      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

GAURI'S BLOG : CARINA NEBULA

Image
                         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

GAURI's BLOG : WHAT ARE THE SHORTCUTS IN SPACE? WORMHOLES?

Image
 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

GAURI's BLOG : IS SPACE TOURISM WORTH SPENDING MILLION DOLLARS?

Image
 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

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
