this is so awesome, hopefully it deploys in space without any issues.

Yup and unlike hubble they can’t send a shuttle up to fix it. Surely they’ve learnt from that though

We may be seeing the last few telescopes costing tens of $billion$.  The science community has noticed Starship and what super-heavy launchers like it will mean,

 

• no need to hyperoptimized for mass, which begets cheaper 

 

• LEO to deep space vehicles capable of  servicing OR replacing/upgrading of sensors etc.

 

• easier replacing of entire telescopes at key vantage points

 

• proposed for a Starship variant, a very large telescope built into the vehicle structure.  No joke.

Exactly, Webb’s 6.5m mirror would fit inside starship without any folds. No part is the best part. The shield would still need to be folded but nothing like the complexity of what they have had to do.

First "real" image from the JWST (aside from the alignment evaluation image released a few months ago)

A deep field image of a galaxy cluster as it appeared 4.6 billion years ago which took about a half a day to image whereas a similar Hubble image would take two weeks.  Incredible.

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

 

Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

 

This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks.

 

The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions, as Webb seeks the earliest galaxies in the universe.

 

This image is among the telescope’s first-full color images. The full suite will be released Tuesday, July 12, beginning at 10:30 a.m. EDT, during a live NASA TV broadcast. Learn more about how to watch.

Images to be released today...

 

  • Carina Nebula: The Carina Nebula is one of the largest and brightest nebulae in the sky, located approximately 7,600 light-years away in the southern constellation Carina. Nebulae are stellar nurseries where stars form. The Carina Nebula is home to many massive stars, several times larger than the Sun.
  • WASP-96 b (spectrum): WASP-96 b is a giant planet outside our solar system, composed mainly of gas. The planet, located nearly 1,150 light-years from Earth, 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, or “Eight-Burst” nebula, is a planetary nebula – an expanding cloud of gas, surrounding a dying star. It is nearly half a light-year in diameter and is located approximately 2,000 light years away from Earth.
  • Stephan’s Quintet: About 290 million light-years away, Stephan’s Quintet is located in the constellation Pegasus. It is notable for being the first compact galaxy group ever discovered in 1877. Four of the five galaxies within the quintet are locked in a cosmic dance of repeated close encounters.

If you hold a grain of sand at arm's length up at the sky, the area of sky it covers represents that Webb image.

    Amazing...

Anyone know if the telescope is going to be basically re taking photos from the Hubbel or will it be tasked with new photos ? 

Both. They already have some side-by-side shots for comparison, but they will be reaching further back into the universe than Hubble could.
