Space Exploration & Discoveries

It's bullshit these blionares are taking trips to space while avoiding their taxes here. Immoral.

Well he had to do it first, they needed to show how safe it is.

I see it as a positive. He plays the guinea pig himself with that much money to spare. Go Branson, go!
He kinda reminds me of that dude:

Probably the most important event for humanity in the past 20 years was today. James Webb Space Telescope launched succesfully into space today. It has been on development 25 years, cost 10B$ and will be the successor for Hubble Space Telescope.

It will take 29 days to get to L2 point, million miles away from Earth. And it should be fully operational in May 2022. It’s 100x more powerful than Hubble and uses infrared scanning technology to see things further away and with greater detail. It will scan thousands of potentially habitable worlds for signs of life, something Hubble wasn’t designed to do.

Following this space since a long time now, now it's come to fruition. Tears in my eye.

Yeah for some it's a life's work. I read that some scientists working on it weren't born when the development first started. Many things needed to be invented for it, and why it took so long.

Thats crazy if you think about it that way. Really thought-provoking

Sun shield has started to open.

Sex me James Webb

This is it: we’ve just wrapped up one of the most challenging steps of our journey to #UnfoldTheUniverse.

With all five layers of sunshield tensioning complete, about 75% of our 344 single-point failures have been retired! pic.twitter.com/P9jJhu7bJX

Two weeks after launch, @NASAWebb has hit its next biggest milestone: the mirrors have completed deployment and the next-generation telescope has taken its final form.

Next up for Webb? Five months of alignment and calibration before we start getting images: pic.twitter.com/BOj5O1HS37

Nish stay safe

5 months of anxiety

It's safe in the L2 orbit. The journey went better than expected and the original 10 year lifespan is doubled now. Can't wait to see 200M years after the Big Bang.

First image released from James Webb Space Telescope, the closest ever image of the Big Bang. What you can see is thousands of distant galaxies, if you put your hand straight to the sky, the area is the size of grain of sand at the tip of your finger.

Here's comparison of Hubble's image of the same area: https://imgsli.com/MTE2Mjc3

There will be more images released tonight.

UHD version of the previous image.


Some context, JWST took the image in less than a day, where as Hubble needed several weeks to expose its image.

So beautifully put man.

edit: barca sux

Oldest galaxy found just after weeks of data collecting, that formed just 300 million years after the Big Bang. And because universe is about 13.8 billion years old, we have now seen in to the past 98% of the whole existence of time.

Stunning.

Also oldest galaxy found again, that was just 180 million years after the start of time.

Webbs image of Jupiter shows northern and southern auroras, just like in earth, and rings like Saturnus has, just fainter.

Forget JWST, forget ELT, forget even the earth sized radio telescope that pictured the black hole. How about a star sized telescope? Apparently we could use the suns gravitational lense to make a star sized telescope for visible light. This would give brightness with a factor of 1 trillion and magnification with a factor of 100 billion compared to now. We could easily see the surface of exoplanets. And it even isn't that far away, as they are almost starting to suggest it to Nasa.

That would be insanely cool if they can pull it off

JWST's photo of Pillars of Creation showing the power of infrared telescope, seeing through the dust. Left photo is with Hubble.

Webbs photo of perfect "Einsteins Ring", of SPT0418-47 galaxy 12B ly away.



Picture showing "gravitational lensing", the same galaxy group seen in different places, in short period of time. Shows how much light can bend depending what kind of path it travels, and what kind of gravitational masses it passes.

Einsteins ring? You mean the one ring to rule them all
