James Webb Space Telescope : Everything you want to know








 What did the galaxy look like 4.6 billion years ago? Well, we don’t have to guess. Thanks to the James Webb Space Telescope built by NASA we know exactly how it looked and it is unbelievable! 


When I said Webb, don’t think of a spider! While you and I were eating pizza and watching tv, thousands of smart scientists worked on creating the most powerful telescope in the world to help us understand space better. 


Now I know what you must be thinking, What is James Webb? Who is he?



The James Webb Space Telescope is the successor of the Hubble space telescope. It has also been called “The next generation of space telescopes”. It has a huge camera. Does anyone have a phone camera that's 6.5 meters across? No right? Well that's the length of the main camera on the James Webb Space Telescope, the largest mirror in space. It also orbits the sun every 182.5 earth days or 6 earth months. It was made by NASA. It is named after James Webb who was a very good NASA administrator.


I talked about the Hubble Space Telescope being the predecessor to James Webb. Let me show the differences of it:


  1. Webb’s Primary mirror is 3 times larger than Hubble’s.

  2. Webb can take images in the infrared spectrum while Hubble takes images in visible and UV light.

  3. Webb orbits the sun while Hubble orbits the Earth


So Webb launched in September 2021 and now finally after 6 months its first images have been sent: Let me show them and explain them.


SMACS0723


This is SMACS0723. The photo above is the highest resolution photo of deep space that has ever been taken and the light captured by Webb in this photo has traveled for more than 13 billion years.


Wasp 96-B





WASP-96 b is a giant planet outside Earth’s solar system that NASA says is composed mainly of gas. The planet, located nearly 1,150 light-years away, orbits its star every 3.4 days. It has about half the mass of Jupiter, and its discovery was announced in 2014.


Southern Ring Nebula


The Southern Ring Nebula, also known as the “Eight-Burst” nebula, is what is known as a planetary nebula: an expanding cloud of gas, surrounding a dying star. It is nearly half a light-year in diameter and is located about 2,000 light-years from Earth.

Stephan’s Quintet




Stephan’s Quintet, also known as Hickson Compact Group 92, exists about 290 million light-years away, and four of the five galaxies within the quintet are what NASA describes as locked in a cosmic dance of repeated close encounters. This, too, was captured within both near- and mid-infrared.

Carina Nebula


The Carina Nebula is one of the largest and brightest nebulae that is visible in the night sky. It is located about 7,600 light-years away in the southern constellation of Carina. The Carina Nebula is home to many massive stars, several times larger than the Sun. This photo from Webb reveals a host of stars that had previously not been visible.

I really like these images as they show us more about the universe. I hope NASA shows more amazing images like this and maybe someday we will go to these places but for now we are unfolding the universe with James Webb.

Should homework be banned?

Image
Homework is a vital part of a student’s life so I choose not to ban homework as it helps us revise our class topics. I know some people don’t like to do homework but I think doing homework helps us learn and become successful in life. The best way of doing homework is to take breaks between assignments like you do Science homework and then take a 2 hour break and do English it is as simple as that. So why is homework important? According to Education Week, an online survey of over 1,000 teachers, 500 parents, and 2,100 students conducted by MetLife,77 percent of students and more than 80 percent of teachers and parents say homework is important or very important. The study also reported that 75 percent of students stated they did at least 30 minutes, while 45 percent said they spend more than an hour on homework each regular school day. Homework does not need to be boring. You can make yourself a points chart and everyday when you complete your homework you earn stickers and if you com...

  Book review -  The Cat gang - Geronimo Stilton Author/Illustrator-Elisabetta  Dami The first reaction I had to the cover page was ‘the book is about bank robbery because in the cover there was a cat robbing a bank. I got this book from the Kahani Box library which delivered it in my April set. A team of 4 bank robbers and 1 cat robs banks in New Mouse city.Can Geronimo and his team stop the robbers and capture them or will the robbers rob all the banks in New Mouse city?Read the book to find out. The main character of the book is Geronimo Stilton.He hates traveling but loves playing golf and telling stories and is good at solving mysteries. I wonder why books like Geronimo Stilton don’t have a central meaning.I am saying this because I feel that the central meaning is important for our lives. The book was amazing it had easy to understand writing,very funny pictures, very funny story and it is hilarious.There is nothing I would change. It is one of the best stories I ev...

Happy birthday Rabindranath Tagore

Image
  Last year my school said to dress up as someone great. I did not know who to dress up as. Then I dressed up as Rabindranath Tagore. That time I did not know who he was but I learnt a lot about him. Since today is his birthday let me tell you what I learnt. Rabindranath Tagore was born on 7th May 1865. He Has composed the National Anthem of India and Bangladesh. He    was the first non-european to win a Nobel prize in literature and the 2nd non-european to win any Nobel prize. Despite his greatness, he had a sad childhood. His mother died early into his life and he was mostly raised by servants and was 1 of 13 surviving children. He has written many poems and many stories although I have not read all of them. I am sure they are interesting. One book I really love by him is Kabuliwala. It is a book about a little girl who is very friendly with a Kabuliwala. She thinks inside his sack are kidnapped children but then understands that he is nice.  I think every child sh...
