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.

Oh we got one.
It's about a team of misfit dogs trained by compassionate humans to be freaking super heroes.

Our story starts with the organization itself.
Rogue Detection Teams.

All photos in this thread are from their very awesome websiteroguedogs.org
@roguedetection The dogs that make up this team are the dogs are ones that society didn’t want.
They are dogs surrendered because of hyperactivity or obsessive behaviours.
These dogs would have had a life of isolation and misery.
This could be a touchy subject for some, but the facts don't lie.
Here are FIVE reasons, based on science, that you should keep your cat inside
---THREAD---
1. Your cat won’t get killed by stuff
Outdoor cats are at risk to be hit by cars, mauled by dogs, eaten by coyotes, and other predators.
Cats could be poisoned by humans OR eat stuff that could kill them.
Or shot.
Outdoor cats die all the time from being outside.
2. Your cat won’t get diseases.
Outdoor cats will come in contact with other cats that are known to carry dangerous diseases.
Even a tiny bit of contact can transmit parasites and diseases like Feline Leukemia and Distemper.
Not great.

Is it training?
Is it the breed?

@caninecognition Science is pretty unanimous when it comes to dogs.
They are unique in how they interact with humans.
A good many scientists feel dogs can understand us in ways other animals can’t.
They can follow a point and hold our gaze.
This is coded in their DNA.
A fluffy giant puppy was the happiest thing in our lives.
One day he had an injury.
Everything turned out ok but we learned harsh lessons.
We hope this story gives potential pet owners some advice.
Bunsen was this adorable, happy puppy.
Every single day was the BEST day of his life.
He was adventurous, always smiling, and attracted a crowd.
Then he broke his toe.
Badly.
To this day we don’t know HOW he broke his toe.
He just started limping and crying.
The happy go-lucky little fuzzball was in pain.
