Canada’s instrument NIRISS on #Webb reveals the distinct signature of water 💧 in the atmosphere of a hot, puffy gas giant planet orbiting a distant Sun-like star. It also shows evidence of haze and clouds that previous studies of this planet did not detect. ☁
The spectrum captured by NIRISS isn’t only the most detailed of its kind to date, but it also covers a remarkably wide range of wavelengths, including a portion of the spectrum that has not previously been accessible from other telescopes.
This part of the spectrum is particularly sensitive to water as well as other key molecules like oxygen, methane, and carbon dioxide. Webb will play a significant role in the search for potentially habitable planets in the coming years.
Each of the 141 data points (white circles) on this graph represents the amount of a specific wavelength of light that is blocked by the planet and absorbed by its atmosphere.

This Webb caught a giant space tarantula!
Take a moment to stare into thousands of never-before-seen young stars in the Tarantula Nebula. Webb reveals details of the structure and composition of the nebula, as well as background galaxies
The Tarantula Nebula gets its name from its dusty filaments. The largest and brightest star-forming region near our galaxy, it's home to the hottest, most massive stars known! This nebula lets us see what star formation might have looked like at its peak in our cosmic history.

Webb’s NIRCam instrument draws attention to bright, hot features, such as the massive young stars in blue. As seen here, its MIRI instrument sees in longer wavelengths of light, uncovering cooler gas and dust deeper within the clouds.

This is what you’ve waited for.
Journey with us through Webb’s breathtaking view of the Pillars of Creation, where scores of newly formed stars glisten like dewdrops among floating, translucent columns of gas and dust.
First, direct your attention to the tips of the pillars, many of which appear tinged with fiery “lava.” Here, young stars periodically shoot out jets of material that collide with the pillars, which can then form wavy patterns. Energetic hydrogen molecules create that red glow.
Also near the edges of the pillars are tiny red orbs. These are the baby stars of the show, only a few hundred thousand years old!

If this majestic landscape looks familiar, you may recognize the original. Here, Hubbles’s iconic view, taken in visible light, is on the left. Webb “sees” in infrared light invisible to our eyes, allowing it to pierce through the dust and reveal stars galore (right).
Why go back to where we’ve been before? Webb’s new look identifies far more precise counts of newborn stars, along with the quantities of gas and dust. This will help us build a clearer understanding of how stars form and burst out of these dusty clouds over millions of years.

Pillars of Creation (NIRCam)
The Pillars of Creation are set off in a kaleidoscope of color in NASA’s James Webb Space Telescope’s near-infrared-light view. The pillars look like arches and spires rising out of a desert landscape, but are filled with semi-transparent gas and dust, and ever changing. This is a region where young stars are forming – or have barely burst from their dusty cocoons as they continue to form.
Newly formed stars are the scene-stealers in this Near-Infrared Camera (NIRCam) image. These are the bright red orbs that sometimes appear with eight diffraction spikes. When knots with sufficient mass form within the pillars, they begin to collapse under their own gravity, slowly heat up, and eventually begin shining brightly.
Along the edges of the pillars are wavy lines that look like lava. These are ejections from stars that are still forming. Young stars periodically shoot out supersonic jets that can interact within clouds of material, like these thick pillars of gas and dust. This sometimes also results in bow shocks, which can form wavy patterns like a boat does as it moves through water. These young stars are estimated to be only a few hundred thousand years old, and will continue to form for millions of years.

Pillars of Creation (Hubble and Webb Images Side by Side)
NASA's Hubble Space Telescope made the Pillars of Creation famous with its first image in 1995, but revisited the scene in 2014 to reveal a sharper, wider view in visible light, shown above at left.
A new, near-infrared-light view from NASA’s James Webb Space Telescope, at right, helps us peer through more of the dust in this star-forming region. The thick, dusty brown pillars are no longer as opaque and many more red stars that are still forming come into view.
While the pillars of gas and dust seem darker and less penetrable in Hubble’s view, they appear more diaphanous in Webb’s.

"This is a whole new chapter in astronomy."
Webb researchers found 2 early galaxies, one of which may contain the most distant starlight ever seen. These 2 unexpectedly bright galaxies could fundamentally alter what we know about the very first stars.

Want a closer look? These two galaxies are thought to have existed 350 & 450 million years after the big bang (left to right). Unlike our Milky Way, these first galaxies are small and compact, with spherical or disk shapes rather than grand spirals.
This discovery suggests that stars might have started forming earlier than expected, perhaps as soon as 100 million years after the big bang. Follow-up observations with Webb’s spectrographs will confirm the distances of these 2 galaxies & help us learn more.

James Webb Space Telescope reveals an exoplanet atmosphere as never seen before
The James Webb Space Telescope (JWST) has just scored another first: a detailed molecular and chemical portrait of a distant world's skies.
The telescope's array of highly sensitive instruments was trained on the atmosphere of a "hot Saturn"—a planet about as massive as Saturn orbiting a star some 700 light-years away—known as WASP-39 b. While JWST and other space telescopes, including Hubble and Spitzer, have previously revealed isolated ingredients of this broiling planet's atmosphere, the new readings provide a full menu of atoms, molecules, and even signs of active chemistry and clouds...

We Just Got The Most Detailed View of an Exoplanet Atmosphere Yet – And It's Active
WASP-39b, a gas giant about 700 light-years away, is turning out to be quite the exoplanetary treasure.
Earlier this year, WASP-39b was the subject of the first-ever detection of carbon dioxide in the atmosphere of a planet outside the Solar System.
Now, an in-depth analysis of data from the James Webb Space Telescope (JWST) has given us an absolute goldmine of information: the most detailed look at an exoplanet atmosphere yet...

Webb’s latest data gives us the first molecular and chemical profile of a distant world, gas giant WASP-39 b. This bodes well for its ability to probe the atmospheres of small, rocky planets like in the TRAPPIST-1 system.
We learn about exoplanet atmospheres by breaking their light into components and creating spectra. Think of a spectrum as a barcode. Elements and molecules have characteristic signatures in that “barcode” we can read.
WASP-39 b is an old friend! In August, Webb showed the first clear evidence of carbon dioxide in a planet outside our solar system. New data from the same planet also shows water, sulfur dioxide, carbon monoxide, sodium and potassium.
What else does the data tell us?
🥇 First detection of sulfur dioxide in an exoplanet atmosphere
💡 Concrete evidence of photochemistry (fundamental for life on Earth)
☁️ Its clouds may be broken up, not one uniform blanket
🔎 Clues to how the planet formed
