Mid-infrared!

Webb sees in near-infrared and mid-infrared wavelengths — invisible light that we feel as heat. This allows the telescope to peer back in time at the early universe, look through dust clouds to see stars being born, and more: https://spaceplace.nasa.gov/james-webb-space-telescope/en/

The light of Earendel, our most beloved star ⭐

Discovered by @NASAHubble, Earendel is the farthest star ever detected. Webb’s fresh look reveals it to be a massive B-type star more than twice as hot and about a million times more luminous than our Sun: https://go.nasa.gov/3Os44aC
#JamesWebb


Earendel is only detectable thanks to a galaxy cluster between the star and us. The cluster’s gravity bends light, magnifying what's behind it—in the case of Earendel, by a factor of at least 4000! Based on its colors, astronomers think Earendel may have a cooler companion star.

Another background galaxy magnified by El Gordo is the bright arc in Box B: El Anzuelo, or The Fishhook. Light from this galaxy took 10.6 billion years to reach Earth! Webb peered through its thick curtain of dust to observe star formation and the assembly of galaxies up close.
#JamesWebb


Take a closer look at one of the magnified background galaxies. The long thin line in Box A is known as La Flaca, or the Thin One. Webb used its infrared sensitivity to spot a red giant star within, the first star of this type observed beyond 1 billion light-years from Earth.
#JamesWebb


Youths!

Webb observed galaxy cluster El Gordo, a cosmic teen that existed 6.2 billion years after the big bang. The most massive cluster of its era, it’s a perfect gravitational magnifying glass, bending & distorting light from distant objects behind it: https://go.nasa.gov/3YkoBCp

Compare Webb’s look at NGC 6822 with its NIRCam instrument versus its MIRI instrument. NIRCam (left) peers through gas and dust, spotlighting countless stars. Meanwhile, MIRI (right) focuses on the galactic dust. Slide between the two views here: https://esawebb.org/images/comparisons/potm2307/
#JamesWebb


Space isn’t always metal.

NGC 6822, a galactic neighbor captured by Webb, has unusually low metallicity, meaning it doesn’t have much in the way of elements heavier than hydrogen and helium. This image combines Webb’s views in near and mid-infrared light: https://esawebb.org/images/potm2307a/

Does the vastness of space fill you with existential...thread? 🧵

This #WorldEmbroideryDay, check out some crafty creations inspired by imagery from the Webb telescope and other NASA missions: https://nasa.tumblr.com/post/724104529319165952/nasa-inspires-your-crafty-creations-for-world

Going goblin mode.

Within the orange-white splotch at the center of this image are 2 chaotic baby stars. Over thousands of years, the pair repeatedly gobbled up, then spat out the gas and dust around them — producing those fiery orange lobes: https://go.nasa.gov/3OFJFjP

Webb detected water in the inner disk of PDS 70, within 100 million miles of the star. Though we’ve seen water in similar disks, Webb’s discovery is the first detection of water in the “rocky planet zone” of a system known to have 2 or more developing planets.
#JamesWebb


On our world, water is life. But how did it get here? Are there similar environments around other stars?

Webb has us one step closer to answers. In a still-developing “solar system,” Webb detected water in the zone where rocky planets like Earth may form: https://go.nasa.gov/3O5LR2j
#JamesWebb


Of course Saturn brought its ring light 🪐

Webb took its first near-infrared look at Saturn on June 25. The planet appears dark at this wavelength, as methane gas in its atmosphere absorbs sunlight — but its icy rings stay bright! Learn more: https://go.nasa.gov/3XtQ5Fr

Cosmic Webb, meet cosmic web 🤝

Galaxies gather in clusters and threads stretching across the universe, punctuated by vast voids. Now Webb has discovered an early strand of this cosmic web — 10 galaxies that existed 830 million years after the big bang: https://go.nasa.gov/433qCnk

Webb — constantly raising the (Orion) Bar for us all.

While observing the Orion Bar, Webb made the first detection ever of a crucial carbon molecule in space. This molecule was found inside a planet-forming disk surrounding a young star system: https://go.nasa.gov/3NLiJyy
#JamesWebb


Here’s a closer look (bottom right) at the star system where methyl cation was found. Its planet-forming disk was bombarded with UV radiation from nearby young stars, radiation typically expected to destroy complex carbon molecules.

Listen to the galaxies of Stephan’s Quintet sing! 🎶

This image, which combines infrared data from the Webb & Spitzer telescopes with X-ray data from @chandraxray, has been "translated" to sound to provide another way of experiencing the cosmos. More: https://chandra.si.edu/photo/2023/sonify7/

TRAPPIST-1 b lacked atmosphere. TRAPPIST-1 c? Much the same. Though thought to be similar to Venus (both in size and amounts of radiation from its star), Webb found it lacks Venus’s thick CO2-rich atmosphere. If there is one, it’s very thin. https://go.nasa.gov/3NBm7vJ

Cosmic smoke & telescope mirrors?

Webb found complex organic molecules similar to smoke or smog in a galaxy more than 12 billion light-years from Earth. This sets a new record for the most distant detection of these big, complicated molecules: https://bit.ly/43M4YEG

Webb’s looked at galaxies from both sides now…

From dust structures in mid-infrared light to stars in near-infrared light, Webb’s dual vision is helping us to see star-forming regions — such as galaxy NGC 5068 — as never before: http://bit.ly/42jAp8f
#JamesWebb


Here's NGC 5068 as seen by just Webb's Mid-Infrared Instrument (MIRI). This image spotlights dust and gas containing newly formed star clusters. Look closely to find asteroid trails (shown as tiny blue-green-red dots)—easier to see here, as stars aren't as bright in mid-infrared.
#JamesWebb


hot exoplanet summer! 🔥

Webb analyzed the atmosphere of an ultrahot gas giant and mapped its temperatures. Despite scorching heat (nearly 5000 F or 2700 C), WASP-18 b has small amounts of atmospheric water — precisely measured due to Webb's sensitivity: https://go.nasa.gov/3C0UuWq
#JamesWebb


Daily hydration reminder 💧

Webb spotted a massive water emission from Saturn's moon Enceladus, spanning over 6000 miles and gushing out at 79 gallons per second. (Webb's data shows Enceladus as a white pixel. Compare its size to the water jet below!) https://go.nasa.gov/42fQbkK
#JamesWebb


Don't forget to water your planets 🪐

Webb provides new insight into how Enceladus' plumes act as a sprinkler system. The moon leaves a “donut” (torus) of water around Saturn as it orbits. About 30% of the water stays in that “donut." The rest is supplied to Saturn & its rings!

Com-et me, bro. ☄️

Webb confirmed the 1st detection of water vapor around a rare type of comet in the main asteroid belt. This suggests that ice from the early solar system can be preserved there—a breakthrough for studying the origins of water on Earth: https://go.nasa.gov/3BucEzm

“Mother of Hubble,” friend of Webb. 💐

We’re honored that Dr. Nancy Grace Roman visited the Webb Telescope at @NASAGoddard in 2017. Here she is shown with our Operations Project Scientist, Dr. Jane Rigby.

For Webb's second year of science, a record-breaking 1,600 proposals were submitted by more than 5,450 scientists from 52 countries. Learn more about how 249 proposals were ultimately selected from Christine Chen at the @SpaceTelescope Science Institute: https://go.nasa.gov/3O5OEKG

Not just out of the park, but out of this world!

Our team participated at the @Royals’ “School Day at The K,” talking to thousands of local students from the Kansas City area about Webb science & engineering.

True to its name, a mini-Neptune is kind of like Neptune, but fun-sized. These exoplanets have thick, hazy atmospheres that can be difficult to peer through. Now Webb has lifted the curtain with the closest look yet at mini-Neptune GJ 1214 b (illustrated): https://www.jpl.nasa.gov/news/nasas-webb-takes-closest-look-yet-at-mysterious-planet
