NASA James Webb Space Telescope First Images

Truly amazing and it'll only get better.

You can click on individual images and then download at the highest resolution so that you can zoom in.

The GIF image below of the Galaxy Field SMACS 0723 (4.6 billion light-years away) is a comparison of James Webb Space Telescope and Hubble Space Telescope.

Isn't that just amazing? I can't wait to see what else it gives us.

[kennethsime]

Pretty darn cool.

[JSumm]

Very cool. Blows my mind that we are looking back in time.

[Evil D]

Truly awe inspiring.

Ok seriously, it's pretty incredible.

[JSumm]

Blast from the past D. I remember that from my childhood.

[Wandering_About]

Amazing stuff. Check out the videos that Smarter Every Day has on it on Youtube. Pretty cool to finally see it in action.

[cabfrank]

Incredible. But what about the other universes?

In the future, we’ll see images of those early galaxies in greater detail.

This is as cool as the the first image of a black hole (M83) that the event horizons telescope captured. Can't wait to see what else is in store for JWST, I'll be watching closely.

One of the plans, this next year, is for the James Webb Space Telescope (JWST) to team up with the Event Horizon Telescope (EHT) to get better images of Sagittarius A* (the supermassive black hole at the center of our Milky Way galaxy) which EHT first imaged in May 2022 (image below).

Getting a handle on the scale of things is my biggest challenge with Webb.

Curation of Webb’s first deep-field image likens its field of view to what you could see through a grain of sand held at the length of your arm.

Just imagine how many grains of sand you would need to have full coverage from your point of view.

And how many galaxies are hinted in this first deep-field image alone?

The scale of the Universe is truly mind-boggling! What’s also incredible is that the visible Universe (all the stars and galaxies we see in various wavelengths) encompass only about 5% of the matter in the Universe. The rest is Dark Matter (27%) and Dark Energy 68%). Beyond speculation, we really don’t know what they are. We know Dark Matter exists due to the gravitational effect it has on visible matter and we know Dark Energy exists due to the accelerated expansion of the Universe.

James Webb Telescope Breaks Record for Oldest Galaxy Ever Observed: The galaxy, called GLASS-z13, dates to just 300 million years after the Big Bang and it’s 13.4 billion light-years away. It’s a very small galaxy at just 1,600 light-years across whereas our Milky Way is about 100,000 light-years across.

Science almost feels like magic sometimes!

Anyone who thinks our planet is the only one to harbor life after seeing the sheer number of galaxies, and the untold billions of stars and planets that are out there, truly has their head in the sand.

Have we ever been visited? Maybe? Probably not. The distances are so vast. And if a civilization has achieved that level of technology then we would be as ants to them as ants are to us. No way to truly communicate.

But we have Spyderco so... I guess it all works out in the end? Lol

The distances even within our own Milky Way galaxy are already vast and outside of it incomprehensibly far. I’m sure there are other living intelligent and sentient beings out there but they’re all far away islands. The Voyager spacecrafts have been traveling since 1977 at a speed of around 38,000 MPH and are now only slightly outside our Solar System. Remember a light-year is about 6 trillion miles and we’re nowhere near traveling at the speed of light which is about 670 million MPH. The fastest spacecraft is NASA’s Parker Solar Probe with a top speed of 430,000 MPH.

U.S. Postal Service announced that the telescope will be featured on new stamps available September 8 (pre-orders begin Aug. 8).

JWST imaged the Cartwheel Galaxy which is usually shrouded in dust 500 million light-years away.

This stuff is crazy. It really makes me ponder existence, ours, and others.
