James Webb Telescope takes releases highest resolution infrared image

NASA’s James Webb Space Telescope (JWST) has released its earliest full-resolution images in a preview of the science quickly to come. These images, showing a deep-field view of the cosmos, two luminous nebulae, a group of fated galaxies and the chemical composition of a huge Exoplanet, are the culmination of decades of effort by scientists and engineers – and they are just the start.

After its launch in December 2021, JWST beamed down its incredibly first images in February, but those were part of the telescope testing procedure and they didn’t yet demonstrate JWST’s complete power. These science images do.

Carina Nebula

One of the brightest nebulae in the sky, the Carina Nebula is an enormous cloud of gas and promising stars. It is about 7600 light years from Earth in the way of the constellation Carina. The top part of the picture, seen above, is full of gigantic, hot stars, shining onto the stellar nursery at the bottom of the image.

“Today, for the first point we’re seeing new stars that were totally hidden from our view,” said JWST scientist Amber Straughn. “We observe examples of bubbles and cavities and jets that are being blown out by these newborn stars. We even observe some galaxies sort of lurking in the background up here. We see examples of structures that frankly we don’t even know what they are. The data is just so prosperous.”

Southern Ring Nebula

This cloud of dust and gas nearby two stars is called the Southern Ring Nebula, or the Eight-Burst Nebula. Both of these pictures show the nebula in infrared, but the one on the right was taken by longer wavelengths than the left one.

The Southern Ring Nebula is on 2000 light years from Earth and almost half a light year across. The dazzling cloud that makes up the ring came from the external layers of one of the stars at the centre of the nebula, which expanded when it reached the ending of its lifetime and transformed from a sun-like star into a white dwarf.

The picture on the right has revealed the stars in astonishing detail, showing that the dimmer, redder star – the one that spawned this nebula – is surrounded by dust, while the brighter star may gust out its have nebula in the future.

Stephan’s Quintet

These five galaxies, called Stephan’s Quintet, are almost 290 million light years from Earth in the way of the constellation Pegasus. Four of the five are engaged in a lethal game of chicken, swooping past one a further closer and closer until, one day in the distant cosmic future, they will most probable smash together and combine.

We have seen them before – in fact, the group of four is the most carefully studied compact group of galaxies – but this picture is far more detailed than any of the earlier ones. It is a mosaic of almost 1000 pictures, building it JWST’s largest image to date.

That detail allows us to see the part around a great massive black hole, the brightest part of the top galaxy. “We cannot see the black hole itself, but we see the matter sort of swirling around and being swallowed by this cosmic monster,” said JWST researcher Giovanna Giardino. This spot is 40 billion times as dazzling as the sun, she said.

The JWST deep field

Released on 11 July, “Webb’s First Deep Field” is the deepest picture of the cosmos ever taken. JWST was designed to take such images to assist us understand the earliest galaxies. The faint galaxies in this picture include the mainly distant galaxy whose composition we have ever been able to measure.

“The previous record-holder, the Hubble Extreme Deep Field, was two weeks of nonstop work with Hubble,” said JWST scientist Jane Rigby during the representation release event at NASA’s Goddard Space Flight Center in Maryland. “With Webb, we took that picture earlier than breakfast… We’re going to be doing discoveries like this each week.”

Now that we have the initial full-resolution images from JWST, the next pace is getting more detailed data so that researchers can create digging into the science.

This includes not just the data after these images, but even deeper observations of the cosmos, from the nearly all distant stars to a bevy of alien worlds to asteroids in our own solar structure.

“This day gives a fresh meaning to ‘as far as the eye can see’,” said US Congressman Steny Hoyer during the picture release event. Over the coming months and years, JWST is expected to carry on pushing the limits of astronomy.

It has enough fuel to carry on observing for at least 20 years, and the release of these fresh images marks the beginning of year one.
