#NASAWebb

Experience the Cosmic Cliffs like never before! #NASAWebb’s iconic image of dusty “mountains” and “valleys” is featured in a new 3D visualization from NASA’s Universe of Learning: webbtelescope.pub/4jRHIh9

Exploring a new neighborhood can be exciting. 🏠 🏡

After its commissioning, #NASAWebb looked at one of our neighbors: dwarf galaxy WLM. This portion of the galaxy, which shows many faint stars, demonstrates Webb’s ability to study stellar populations: https://bit.ly/3XUcn4y

$Thousands of clearly differentiated objects of various color, size, shape, and brightness. Most of the objects are points or solid circles of reddish-orange, blue, or white light. These are the stars that make up the WLM galaxy. A few blue-white foreground stars with Webb’s distinct 8-pointed diffraction pattern, and a number of spiral and disk-like background galaxies are also visible.$

Hot sub-Neptunes are larger than Earth, smaller than Neptune, and orbit closer to their stars than Mercury orbits the Sun. These planets are common across the galaxy, but absent from our solar system. Check out what #NASAWebb discovered: https://webbtelescope.pub/4jcqydW

Illustration showing a large fuzzy blue planet in the foreground, and an orange-yellow star, which appears much smaller, in the background. The side of the planet facing the star is lit, and the side facing away is dark. The boundary between the lit and dark sides is fuzzy. The atmosphere is almost homogeneous in color and texture, with extremely subtle variations and no sign of a surface. The black background of space is scattered with tiny white points of light. The words “Artist’s Concept” is in the lower left corner.

Slow your scroll! Watch an animation showing how winds and light from massive stars form pillars. The pillars’ tips are the densest.

NGC 604, seen here by #NASAWebb, contains more than 200 of the hottest, most massive types of stars. All of these stars are in the early stages of their lives, giving astronomers and opportunity to study their development: https://bit.ly/3FkTe5g

$At the center of the image is a nebula on the black background of space. The nebula is comprised of clumpy, red, filamentary clouds. At the center-right of the red clouds is a large cavernous bubble, and at the center of the bubble there is an opaque blueish glow with speckles of stars. At the edges of the bubble, the dust is white. There are several other smaller cavernous bubbles at the top of the nebula, including two tiny cavities at the top center of the image. There are thousands of stars that fill the surrounding area outside the nebula, most of them are yellow or white. At 11 o’clock and 6 o’clock there are extremely bright stars with 8 diffraction spikes. There are also some smaller, red stars and a few disk-shaped galaxies scattered across the image.$

Today is #WorldPenguinDay! This infrared image from #NASAWebb, taken to mark its second year of science, shows an interaction between a distorted spiral galaxy at center, the Penguin, and the compact elliptical galaxy at left, the Egg.

Take a closer look: webbtelescope.pub/3EP21MO

$Arp 142, two interacting galaxies, observed in near- and mid-infrared light. At left is NGC 2937, nicknamed the Egg. Its center is the brighter and whiter. There are six diffraction spikes atop its gauzy blue layers. At right is NGC 2936, nicknamed the Penguin. Its beak-like region points toward and above the Egg. Where the eye would be is a small, opaque yellow spiral. The Penguin’s distorted arms form the bird’s beak, back, and tail. The tail is wide and layered, like a beta fish’s tail. A semi-transparent blue hue traces the Penguin and extends from the galaxy, creating an upside-down U over top of both galaxies. At top right is another galaxy seen from the side, pointing roughly at a 45-degree angle. It is largely light blue. Its length appears approximately as long as the Egg’s height. One foreground star with large, bright blue diffraction spikes appears over top of the galaxy and another near it. The entire black background is filled with tiny, extremely distant galaxies.$

The blue star cluster shining in the center of the Tarantula Nebula—seen in this #NASAWebb image, was born within the ribbons of silk-like dust that surround it. In time, all of this dust will either be blown away by or absorbed into new stars and planets: https://bit.ly/4bI5Tv5

$A star-forming nebula. The nebula is composed of tan-colored clouds with rust-colored highlights, surrounding a black central area containing a bright cluster of sparkling pale blue stars that scatter outward from a densely packed center. The clouds toward the center are brighter than those toward the edge. The bottom left and the top right of the nebula appear more clear of any clouds of dust and gas. One bright yellow star stands out in the central open area, showing off Webb’s eight-pronged diffraction pattern.$

Explore the formation of a star, as only #NASAWebb can. This 3D tour exposes the structures around the protostar L1527 IRS in infrared light. Telescopes that observe visible light see L1527 as a dark, featureless cloud.

This new #NASAWebb image shows a dying star in unprecedented detail. Mid-infrared light highlights tangled patterns in the rings and holes in the pink interior. This scene was produced by two overlapping stars that “pop” with blue spikes at center: https://bit.ly/424Lygw

$What looks like a single large, bright star but is two shines with bright purple diffraction spikes at the center of a large, diffuse cylinder of gas and dust that is tipped to the right. At the center is a bright pink clumpy cloud that takes up about 25% of the view. The pink region has some holes. Beyond that are two large rings tipped at a 60-degree angle that mark the ends of the cylinder. They appear joined at top left and bottom right. The edges form shallow V-shapes that go inward. The rings appear orange at top left and bottom right, and are blue at bottom and center right. There is diffuse orange material around the body. The black background of space is speckled with tiny stars and galaxies mostly in blues and yellows. A bigger blue star with spikes is just below and to the left of the central stars, but it is slightly smaller. Areas Webb did not observe appear black along the top edges, a thin vertical near the nebula at top left, and at the bottom left and right corners.$

A cavernous area fit for a dragon. 🐉

#NASAWebb revealed more than 200 massive, young stars among the pillars of gas and dust in star-forming region NGC 604. This area is more than 2.7 million light-years from Earth in the Triangulum galaxy: https://bit.ly/4icfWLh

At the center is a nebula on the black background of space. The nebula is composed of wispy filaments of light blue clouds. At the center-right of the blue clouds is a large cavernous bubble. The bottom left edge of this cavernous bubble is filled with hues of pink and white gas. There are several other smaller cavernous bubbles at the top of the nebula, including two tiny cavities at the top center of the image. There are hundreds of dim stars that fill the surrounding area of the nebula.

The “killer” came from inside the star system! #NASAWebb conducted a post-mortem of the first-ever observed planetary engulfment event, when a star swallows an orbiting planet. What it found was surprising: https://webbtelescope.pub/4iOzfe6

A four panel illustration, with two boxes on the top row and two boxes on the bottom row. They are labeled: 1, 2, 3, 4. Panel 1 shows a host star, which looks like an orange globe with flares coming out on various sides. There is a blue line with arrows forming a spiral around the star. At 2 o’clock in the outer spiral, furthest away from the star, there is a blue planet. Panel 2 shows the same star and lines, but the planet is now at 7 o’clock and closer to the star. It is a little stretched out toward the star, appearing like an American football or rugby ball instead of a sphere. Panel 3 shows the same star and lines, but the planet is fully engulfed by the star, with big flares coming out where the planet and star collided. Panel 4 shows the aftermath, with a very transparent cloud of blue dust spread out from the star. A dark orange horizontal ring of material circles the host star.

The jets seen in Herbig-Haro 30, observed by #NASAWebb, are a part of the star formation process. As the star gathers material, much of that material is launched back out along the star’s poles as high-velocity jets.

An edge-on view of a protoplanetary disk around a newly formed star, Herbig-Haro 30. The horizontal brown disk divides two concave, blue disks. The bottom disk is slightly more diffuse, with some filaments of gas and dust trailing off toward the bottom left, while the top disk is uniform. A white glow, indicating the central star, emanates from the center of these disks. Two mostly red jets of high velocity gas shoot in both vertical directions. The jet shooting downward is diffuse and quickly fades close to the center. In comparison, the jet shooting upward is far clearer, making it all the way to the top.

The Crab Nebula—the result of a supernova in 1054—originally appeared as a bright, new star that was visible even in the daytime. Learn more about this storied supernova remnant on a poster of this observation from #NASAWebb: https://webbtelescope.pub/41VJ6rf

A vertical poster with an image of the Crab Nebula against a black background. On the oval-shaped nebula’s exterior lie curtains of glowing red and orange fluffy material. Translucent thin ribbons of smoky white lie within the remnant’s interior, brightest toward its center, and become more diffuse further outward. A faint, wispy ring of white material encircles the very center of the nebula. There are many blue, red, and yellow points throughout the image. Along the bottom is a series of thin vertical bars ranging from purple at left to blue, green, yellow, orange, and red at right. Bars are separated slightly, with black in between. Bar colors are brightest at the bottom, fading up to black. Brightness varies from bar to bar, giving the array an undulating feel. At upper right is text that reads, “National Aeronautics and Space Administration” and NASA’s blue, white, and red meatball insignia. Title text appears at lower left that says, “James Webb Space Telescope: Crab Nebula.”

New observations from #NASAWebb have better constrained the size of asteroid 2024 YR4, and have given researchers insights about how to study future small, fast-moving objects, including the next one that might be heading our way: https://webbtelescope.pub/4lenO0W

A collage of three images primarily showing the black expanse of space. Two-thirds of the collage show one image of a black background sprinkled with stars and small, blurry galaxies in orange, blue, and white. On the right side of the main image, not far from the top, a very faint dot is outlined with a white square. Two images at right, in a column show zoomed in views of this area. The top box is labeled NIRCam and shows a fuzzy dot at the center. The bottom box is labeled MIRI and shows a fuzzy pinkish dot at the center.

Recap some of #NASAWebb’s biggest early-universe discoveries (so far) with the astronomers who are doing the science. https://youtu.be/gCiVrAFz9P0

Using the unique infrared sensitivity of #NASAWebb, researchers can examine ancient galaxies to probe secrets of the early universe. Recently, a bright hydrogen emission from a galaxy in an unexpectedly early time in the universe’s history has been identified. (1/4) 🧵

A small red dot is in the middle of the image. To its upper left is a face-on spiral galaxy, and to its lower right is an edge-on spiral galaxy. A handful of other small background galaxies are seen against the black background of space.

For the first time, astronomers were able to capture bright auroral activity on Neptune, thanks to #NASAWebb’s infrared capabilities: https://webbtelescope.pub/424vcTI

A two-panel horizontal image. On the left is Neptune observed by the Hubble Space Telescope. It is a blue circle, tilted about 25 degrees to the left. There are white smudges at 7 o’clock and just above 5 o’clock. At right is an opposing view of the planet, using data from Hubble and Webb. It is a multi-hued blue orb. There are white smudges in the same spots as the image on the left, but also at the center of the planet and at the top. There are cyan smudges vertically along the right side, and the top of these areas are more translucent than the bottom.

#NASAWebb provides high-resolution details of Herbig-Haro 49/50—an outflow from a nearby still-forming star and background galaxies. Webb reveals the fuzzy object at the tip of the outflow in the Spitzer image is actually a distant spiral galaxy: https://webbtelescope.pub/4iGQg9K
