Why is the photo from the JWST so profound?
Let’s talk about it in
THE
SUPER
AWESOME
SCIENCE
THREAD! #TSAST
1. DISTANCE
The photo is of galaxies a long time ago and far, far away.
Since space is so big, distances are measured in light years. Light travels 5.88 trillion miles in a year. The galaxies used to make the image are 4.6 billion light years away. 4.6b x 5.88t miles = 🤯
2. TIME
The galaxy cluster the telescope aimed at BENT the light around them due to their gravity and it has magnified EVEN more ancient stuff behind them.
13 billion years ancient actually.
13 000 000 000 years old.
It’s a number so hard to wrap your head around.
3. TIME part II
The Big Bang is theorized to have occurred 13.8 billion years ago. This means the photo released is getting close to the start of space-time.
The beginning of literally everything.
Astronomers are confident they can get photos of stuff 13.5 billion years old.
4. WE SO SMOL
Every speck of light in that photo is a galaxy.
Our galaxy, the Milky Way, holds billions of stars and each star probably has more than one planet orbiting it. That’s billions of planets.
Trillions and Trillions of worlds are in this photo.
We are so smol.
5. TIME TRAVEL
Likely everything in the oldest part of the photo is different today. Bright stars do not last 13 billion years. The photo is of the past as the light took BILLIONS of years to reach us. Those stars in those galaxies are long gone.
We are looking at echos.
6. IMPROVEMENT
I’ll just post the photo of HOW much better the JWST is to Hubble.
It’s like watching a kid in school get glasses and their vision improves. They can see the board.
7. THIS IS THE FIRST
JWST will be taking thousands of photos, and it has different objectives. It will be able to analyze the atmosphere of exoplanets and determine if life could live there. It can LOOK THROUGH stuff to get pictures.
This is why we are all so excited.

It's one of the most popular dog breeds in the world.
It's cute, wrinkly face is just asking to be kissed, and it's warm personality loves cuddles.
It isn't without health problems and controversy though.
It's the Pug! Let's learn more! 🧵
Pugs probably date back over 2,000 years to ancient China, where they were treasured by emperors and lived luxurious lives.
They were brought to Europe in the 16th century by Dutch traders, quickly becoming favorites among European royalty.
As Pugs spread across Europe, they were refined and standardized, leading to the distinctive breed we know today.
The breed's signature features include a short muzzle, curled tail, and expressive, large eyes, which contribute to their unique and endearing appearance.
Did you know that in 2017 physics attempted to prove that cats are beyond bendy.
A wild and weird test took place that concluded Cats are liquids.
Let's get into it!
In 2017, he published a study in the journal Rheology Bulletin, where he applied principles of fluid mechanics to cats.
The study humorously examined whether felines can indeed be classified as liquids based on their ability to conform to the shape of a container!
Liquids, according to physics, have no fixed shape and take the form of their container.
Fardin applied this definition to cats—because, as any cat owner knows, these pets love curling up in bowls, boxes, and any small space they can squeeze into.
