Michelle's second paper showed the discovery from the fabulous new WEAVE instrument in the Canary island. This IFU found a surprising bar of iron in the centre of the ring nebula. It doesn't seem to be a jet feature, so what is it?!? 🔭 ☄️ arxiv.org/abs/2601.10635

The stunning WEAVE large IFU dataset. The ring nebula is clearly seen in the three pointings with WEAVE. Each pixel is also a spectrum, allowing them to probe the kinematics and chemistry of the ring.

Thread 🧵 An object's appearance starts with which wavelengths it reflects/absorbs under the incoming light. But the key insight from author's piece (and vision science in general) is that color isn't 'in' the object or even 'in' the light spectrum itself. 1/5

Slender glowing ribbon of gas, tilted like a narrow pencil, stretches diagonally through the deep space. Delicate red and blue threads weave and shimmer along its sharp form, brightest at the upper-right tip. Distant stars dot the void behind, dominated by the red of ionized hydrogen.

Sloan Digital Sky Survey image of Arp 285, also known as NGC 2854 and NGC 2856. This pair of galaxies is connected by a bridge of material, indicating a past interaction. The upper galaxy, NGC 2856, also has a clumpy tail perpendicular to its disk. Credit: SDSS Source

$A somewhat low-res image of a pair of widely-space interacting spiral galaxies. The galaxy in the top left has a bright disk seen at a slight angle so that it appears oval-shaped. Its spiral arms are fainter and hard to see. A thin, blue, clumpy line extends above the galaxy, perpendicular to its disk. The galaxy in the lower right has a strong bar and two spiral arms, forming a distinct S shape. The bar is brighter and yellow-ish. The arms are bluer and dotted with teal star clusters. Faint streams of blue material extend outwards from the ends of the spiral arms. The top stream almost connects with the galaxy in the top left. Several foreground stars are seen as bright points with eight diffraction spikes. The black background of space is dotted with stars and small background galaxies$

🧵 This JWST's view of the Red Spider Nebula (NGC 6537) is spectacular! It's about a planetary nebula i.e. the remnants of a Sun-like star shedding its outer layers, ionizing the ejected gas. Webb's NIRCam reveals hot dust & stunning details amid stars. ➡️ esawebb.org/images/potm2... 🔭 🧪 1/6

"A large planetary nebula. The nebula’s central star is hidden by a blotchy pinkish cloud of dust. A strong red light radiates from this area, illuminating the nearby dust. Two large loops extend diagonally away from the centre, formed of thin ridges of molecular gas, here coloured blue. They stretch out to the corners of the view. A huge number of bright, whitish stars cover the background, also easily visible through the thin dust
layers."

As she flew 400 km above Earth, NASA astronaut Nichole Ayers caught a gigantic spark with blue flashes and red tentacles shooting upwards. In the image, a blue jet propagates into space towards the upper layers of the atmosphere. The beam of light is followed by red flashes spreading like tentacles across the sky.
