Pandora’s Cluster—seen by #NASAWebb—has a concentration of mass so great that space around it is warped by gravity and can magnify sources of light behind it. As a result, the cluster has helped astronomers identify numerous objects in the early universe: https://bit.ly/4s1wnzP
A crowded field of galaxies on a black background, with one large star just right of center. Three areas are concentrated with larger white hazy blobs on the left, lower right, and upper right above the single star. Scattered between these areas are many smaller sources of light; some also have a hazy white glow, while many others are red or orange. Different galaxy shapes are detectable, like spirals, ovals, and arcs.

NOVEMBER 10 at 8 pm ET: The Cigar Galaxy has been notoriously difficult to study. It contains large amounts of dust, making its disk nearly impenetrable at optical wavelengths. Now #NASAWebb has pierced through its dust to reveal its structure in incredible detail.
Secrets of the Cigar: JWST Unveils the Prototype Starburst Galaxy
The Cigar Galaxy, a.k.a Messier 82 (M82), is the prototype for a unique class of galaxies: starbursts. Starburst galaxies are undergoing rampant star formation, and, in fact, serve as stress tests of how well we understand star formation and its impact ...

Cat got your tongue? That’s how we feel when looking at new images of the Cat’s Head Nebula by Hubble and #NASAWebb. With its glowing eye—likely a star buried by gas and dust—this nebula has arrived in time for Halloween: https://news.stsci.edu/4sq4Los 🔭
3-panel image of the Cat’s Head Nebula, a filament of dust that stretches from the bottom to almost the very top. It has a narrow, irregular shape that resembles a cat sitting with its back toward the viewer and its tail extending downward. The cat’s head is turned toward the right, revealing a glowing eye. Each image’s bottom left corner has a label. From left to right: Hubble WFC3; Webb NIRCam; and Webb MIRI. In Hubble’s visible light, the filament of dust is dark brown and opaque with a glowing red eye. The top half of the background is blue and the bottom half ranges from yellow to dark orange. The middle near-infrared image shows the filament as orangish-brown with a yellow eye. The background is mostly blue and has many yellow and blue points of light. The right mid-infrared image shows the filament as bluish-gray and its eye as white. The background is mostly red and scattered with yellow and blue points.

Two galaxies are merging. Near the top is a spiral galaxy with thick arms in fiery oranges, whites, and reds. At the bottom is a faint, hazy bowl-shaped galaxy marbled with grainy white ribbons and hot pink specks. Where the two shapes collide in the center, the galaxy appears chaotic, like a firework photographed the moment it explodes.

The @NASAWebb telescope recently spotted stars brewing in this cosmic cauldron. This region of toil and trouble, named N159, is 161,000 light-years from Earth, in the Large Magellanic Cloud.
A nebula made of clouds of gas and dust with stars forming within. In the center and out to the left it is filled with thin, wispy blue gas that forms delicate layers. Around this are thicker orange clouds with dark ridges. Thin red filaments of gas cross the center of the nebula. Glowing bubbles in the gas contain dense, very bright clusters of stars. In the edges, distant stars are visible as bright points on a dark background. Credit: ESA/Webb, NASA & CSA, E. Sabbi, M. Zamani (ESA/Webb)
