A section of the Cat’s Paw Nebula, a local star-forming region composed of gas, dust, and young stars. Four roughly circular areas are toward the center of the frame: a small oval toward the top left, a large circle in the top center, and two ovals at bottom left and right. Each circular area has a luminous blue glow, with the top center and bottom left areas the brightest. Brown-orange filaments of dust, which vary in density, surround these four bluish patches and stretch toward the frame’s edges. Small zones, such as to the left and right of the top-center blue circular area, appear darker and seemingly vacant of stars. Toward the center are small, fiery red clumps scattered among the brown dust. Many small, yellow-white stars are spread across the scene, some with eight-pointed diffraction spikes that are characteristic of Webb. A few larger blue-white stars with diffraction spikes are scattered throughout, mostly toward the top left and bottom right. In the top right corner is a bright red-orange oval.

An image of a nearby star and its vicinity. The star itself has been blocked out and its bright light has been removed, appearing black. A dashed circle with a star symbol at the center of the image marks the star’s location. A fuzzy blue disk surrounds the star. An orange spot, near the star and inside this disk around 2 o’clock, is identified as a planet orbiting the star. A fainter orange spot at the lower left edge marks a distant star.

A compact brightening bursts to life at the edge of a sunspot! This multi-instrument figure showcases high-resolution observations of the same active region. Panels a–b show data from the Helioseismic and Magnetic Imager at the NASA Solar Dynamics Observatory. Panels c–e show spectra from the ViSP instrument at the Inouye. Panels f–h show images from the VBI instrument at the Inouye using three different light filters known as G-band, Hβ, and Ca II K. The panels reveal a small-scale, transient brightening (indicated by the black arrow) occurring at the boundary between opposite magnetic polarities (inside the blue box). One arcsecond corresponds to 720 km on the Sun.

A three-panel image, two at the top and one stretched across the bottom. At the top of the image is the title “Three Future Scenarios for Milky Way and Andromeda Encounter.” This title is extended over all three panels. In the top left panel, two spiral galaxies are widely separated against the black background of space. Beneath these galaxies are the words “Galaxies bypass at 1 million light-year separation.” In the top right panel, two face-on spiral galaxies are close together. Their spiral arms appear stretched toward each other. At the bottom of this panel are the words “At 500,000 light-years, dark matter provides friction that brings galaxies to a close encounter.” In the bottom panel, two spiral galaxies have collided, resulting in a broad X-shaped patch of milky white. Mottled clouds of dark brown dust are superimposed. At the bottom of this panel are the words “A 100,000 light-year separation leads to a collision.”

Six-panel illustration marked "Artist's Concept." The upper left panel shows the silhouette of supermassive black hole that is adrift inside a galaxy. The middle upper panel shows a yellow star drifting near the black hole. The three following panels show the star being shredded in bright white concentric streamers followed by a white explosion. the bottom right panel is an external view of the galaxy showing a bright white star-like object that is the site if the explosion as viewed in X-rays and visible light.

Composite shows four Hubble images in quarters. At top left is a crisp view of Mars in shades of orange, blues, and browns. At top right is planetary nebula NGC 2899, which is shaped like a single macaroni noodle, with its central torus appearing semi-transparent and blue and green, and its top and bottom edges in orange. At bottom left is a tiny portion of the Rosette Nebula. Very dark gray material shaped like a triangle takes up the center. At bottom right is barred spiral galaxy NGC 5335 with a milky yellow center that forms a bar surrounded by multiple blue star-filled spiral arms that wrap up counterclockwise.
