Time to reinvent the wheel. Here’s the Cartwheel Galaxy in a whole new light — as a composite image from 2 instruments on the Webb telescope. Webb uniquely offers not just a snapshot of the galaxy’s current state, but also a peek into its past & future: go.nasa.gov/3SfEQgR
A large galaxy on the right, with two much smaller companion galaxies to the left at 10 o’clock and 9 o’clock. The large galaxy resembles a speckled wheel, with an oval outer ring and a small, off-center inner ring. The outer ring contains pink plumes like wheel spokes, with dusty blue regions in between. The pink areas are silicate dust, while the blue areas are pockets of young stars and hydrocarbon dust. The inner ring is smoother, filled in with a more uniform pale pink. This smaller ring is interwoven with thin, orange-pink threads. On the galaxy's right edge, a bright white star with 8 diffraction spikes shines. The two companion galaxies to the left, one above the other, are about the same size and both spiral galaxies. The galaxy above is a reverse S shape but similar in coloring and texture as the large ring galaxy. The galaxy below is smoother and largely white, with a blue tinge. The background is black and full of more distant, orange-red colored galaxies of various sizes.

Thanks for all the assists! NASA’s #GravityAssist podcast is concluding after five fantastic years of telling the stories of the people who make space exploration happen. Tune into the final episode to re-live some of the highlights: go.nasa.gov/3BZhh6d

“I had many opportunities…to try hard things. So sometimes I tried them & I succeeded. And that gave me a little bit of a boost to say, okay, maybe Galileo and Darwin could do great things. Maybe I could do something too.” - Webb scientist John Mather 🔊 go.nasa.gov/3zGZFu1

A “gravity assist” is when a spacecraft slingshots past a planet to gain more speed. It’s also the inspiration you get to go into your career or your chosen area of study. What was your #gravityassist?

’s first image reveal! 🥳 On the right is that image from the infrared observatory, showing galaxy cluster SMACS 0723. Hubble’s view on the left demonstrates the complementary nature of the telescopes across a broader range of wavelengths!
The background of space is black. Thousands of galaxies appear all across the view. Their shapes and colors vary, mostly appearing in shades of white, yellow, and orange. In addition, several stars appear in blue with diffraction spikes. These galaxies are part of the galaxy cluster SMACS 0723, and they are warping the appearances of galaxies seen around them.
The background of space is black. Thousands of galaxies appear all across the view. Their shapes and colors vary. Some are various shades of orange, others are white. Most stars appear blue, and are sometimes as large as more distant galaxies that appear next to them. A very bright star is just above and left of center. It has eight bright blue, long diffraction spikes. Between 4 o’clock and 6 o’clock in its spikes are several very bright galaxies. A group of three are in the middle, and two are closer to 4 o’clock. These galaxies are part of the galaxy cluster SMACS 0723, and they are warping the appearances of galaxies seen around them. Long orange arcs appear at left and right toward the center.

Did somebody say new Webb images? #ICYMI, we just dropped an incredible new Cartwheel Galaxy image, and yes, more images will be rolling out over the coming weeks! But there’s a few things you should know first about Webb’s next steps 👇

Science is a collaborative process! You may have seen some preliminary findings from Webb data already. But before NASA can publicize news results, we have to wait for findings to be peer-reviewed — meaning that scientists have checked each other’s work.

Here’s that galaxy again, as seen just through Webb’s MIRI instrument. While Webb’s NIRCam reveals previously unseen young stars, MIRI reveals regions rich in hydrocarbons and chemical compounds, such as silicate dust — similar to dust on Earth!
A large galaxy on the right, with two smaller companion galaxies to the left 10 o’clock & 9 o’clock. The large galaxy dominates the frame. It resembles a ghostly wheel with spindly blue-white spokes revolving around a glowing core. The outer edges of the wheel are faint dots of yellow, pink and blue, with some gaps in between. The bottom right edge is marked by a large 8-pointed star. The smaller galaxies on the left look very different from each other. The top galaxy appears to be constructed of the same yellow, pink, & blue speckles as the larger galaxy’s outer ring, with a similar light blue core. Its shape is less recognizable as a spiral; it looks like a chaotic oval smattering of dots. The galaxy below it glows as one large point of blue light. It starts almost white at its core and fades outward to darker and darker blue until the color dissipates into the black behind it. Sprinkled in the black background are specks of pink, blue, yellow & orange, which are distant galaxies.

Believe it or not, this galaxy was probably your average spiral galaxy before it collided with a smaller galaxy over 400 million years ago. Now, it’s made up of 2 rings — a bright inner ring and a surrounding, colorful ring. Both expand outwards from the center like pond ripples.

Need a new perspective? Here’s some Webb-inspired #MondayMotivation: Sometimes, seeing clearly requires looking at things with a fresh set of eyes. When you’re able to peer through the dust, that’s when you can reveal even more stars. ✨
GIF that transitions from a Hubble image of the Carina Nebula to the same region as seen by Webb. Both images are divided between a blue “sky” dotted with stars and an orange-brown “mountain range” below it. The brown “mountainous” area features a prominent knob sticking out on the left side. Starting with the Hubble image, the blue portion is a more faded color and mixed with shades of green. Some pink points of starlight, each with 4 diffraction spikes, poke through the blue. The orange-brown portion is dusty, and the few stars that can be seen are only tiny dots of pinkish red. As the GIF fades into the Webb image, we see that Webb’s blue portion is much more rich, dark and vivid in color. Compared to Hubble, a multitude of stars in shades of light orange and blue are visible, including two giant six-pointed stars on the very right. The orange-brown portion is also dotted with stars galore, each with a set of 6 diffraction spikes.
