A black-and-white map showing the spatial distribution of planetary nebulae (PNe) in the M31 galaxy. The points form a dense, diagonal band stretching from top-left to bottom-right, representing the galaxy's outer disk against a faint grid with horizontal divisions of 5 minutes and vertical divisions of 1 degree. Dot sizes indicate relative brightness. Within this dense field, 16 specific target PNe are circled and labeled from PN1 to PN16. These labeled targets are distributed throughout the map, with PN6 and PN7 near the top edge, PN1 on the far left, PN8 towards the bottom, and the remaining labels clustered around the dense central and right-central regions of the mapped area.
An image of the planetary nebula Kohoutek 3-46 against a dense, dark background filled with glittering stars of varying brightness and colors. The central nebula has a distinct bipolar, butterfly-like shape, featuring two large, glowing orange-red lobes expanding outwards from a pinched middle. This central waist is highlighted by a bright, whitish-blue equatorial ring. Several bright stars with diffraction spikes are visible around the nebula, contrasting with the soft, ethereal glow of the expanding gas.

A 3x3 grid of images titled "Gemini-North | 2026-06-01 to 2026-06-09". A legend denotes yellow for "GMOS-N" and blue for "MAROON-X". The panels show various deep space objects: dense star clusters, individual brightly colored stars, and a prominent spiral galaxy in the middle-right panel. Each image has an instrument label in the bottom-left corner. Top row (left to right): three MAROON-X images of starfields. Middle row: three GMOS-N images, the third showing the spiral galaxy. Bottom row: MAROON-X, GMOS-N, and MAROON-X images of starfields.
A 3x3 mosaic of nine images taken by the Gemini-South telescope between June 1 and June 9, 2026. A legend at the top indicates yellow text corresponds to the GHOST instrument and blue text to GMOS-S. Each square features a different deep-space view with its instrument labeled in the bottom-left corner. The top row shows a GHOST image of a bright orange star, alongside two GMOS-S images of varied starfields. The middle row features a bright, cloudy GHOST nebula, a GMOS-S magenta-tinted starfield, and another GMOS-S starfield. The bottom row displays a sparse GMOS-S starfield, followed by two dense GHOST star clusters—one glowing golden-orange and the other bright blue.

A long-exposure night photograph of the Gemini South Telescope building sitting on a dark hilltop on Cerro Pachón against a glowing orange horizon. Above the observatory, thousands of star trails form concentric circular arcs swirling across the dark blue sky toward the upper left. A vibrant yellow laser beam extends vertically from the center of the illuminated telescope dome straight up into the starry sky. A winding road at the base of the hill shows streaks of bright yellow light from a moving vehicle.

A four-panel line graph showing spectral flux versus wavelength in micrometers. The y-axis on all panels is labeled "Flux F_lambda 10^(-17) W/m^2/micron" and the x-axis is "Wavelength micron". Each of the four panels focuses on a different wavelength range (approximately 0.95-1.1, 1.2-1.35, 1.5-1.65, and 2.0-2.2 microns). The graphs contain multiple colored spectral lines (black, red, cyan, and light gray) displaying various peaks and troughs. Text labels with chemical formulas are placed above specific spectral features across the panels, pointing out the absorption or emission bands of H2O, NH3, H2, and CH4, often appearing in combinations (e.g., NH3+H2, H2O+NH3) at their characteristic wavelengths.
A dense image of a crowded star field against a dark background. Thousands of stars of different sizes and hues fill the frame, ranging from soft, pinpoint orange and reddish stars to luminous cyan and blue-white stars. Several of the brightest blue stars feature distinct four-pointed diffraction spikes extending outward, with two particularly prominent bright stars located near the top right. This image captures the stellar field surrounding the host galaxy of gamma-ray burst GRB 250702B.

A detailed view of the unbarred spiral galaxy NGC 772 against a dark, star-speckled background. A glowing white core sits near the top center, surrounded by intricate reddish-brown dust lanes and blue-tinged spiral arms winding outward. One prominent outer arm sweeps down toward the lower left, filled with clusters of bright blue stars and glowing gas.

A multi-panel figure analyzing the radio source J1601+3102:Left Panel: A high-resolution radio continuum map showing two emission components—a northern lobe and a southern lobe—separated by 10.5'’ (66 kpc). A color bar indicates radio flux density in mJy.Top Right Panels: Three small radio maps comparing the source across different radio surveys at increasing frequencies: LoTSS (144 MHz), FIRST (1.4 GHz), and VLASS (3 GHz).Bottom Right Panel: A log-log plot of total flux density vs. frequency (100–3000 MHz). Three power-law fit lines demonstrate steep spectral indices (alpha ~ -1.26 to -1.27) for the total emission, northern lobe, and southern lobe.
An image of the young stellar jet MHO 1502, captured by Gemini South. Set against a dark, dusty cosmic backdrop, a series of bright, glowing blue and cyan knots extend across the center of the frame, forming a curved, segmented jet emitted by forming stars. Dozens of reddish-orange and white background stars are scattered across the scene. Near the upper right, a dense, luminous cluster of stars glows intensely against a cloud of white and blue nebulosity in this star-forming region.

A wide-angle night photograph featuring the metallic dome of the Gemini North telescope on the left, set against a dark mountain silhouette. Above, a brilliant, luminous arch of the Milky Way galaxy stretches across a star-filled sky. In the background, low-lying clouds glow orange from city light pollution, while an orange glow on the bottom right illuminates the horizon from the active Kīlauea volcano.

This is a black-and-white, negative astronomical image of a dense star field, where stars appear as black dots against a white background. Several colored annotations are overlaid on the stars: A large blue polygon shows the VLT KMOS seeing-limited observations. Within the blue outline, three smaller red rectangular boxes represent the Gemini NIFS AO observations. Near the center of the image, a green cross marks the position of Sgr A*. In the upper right corner, a purple compass graphic indicates the directions of North (N) and East (E). In the lower right corner, a purple scale bar is labeled '10"'.
An image showing two spiral galaxies against a dark background dotted with stars and distant galaxies. The galaxy on the lower left is angled, displaying a bright white core and sweeping spiral arms interspersed with dark brown dust lanes. The galaxy on the top right is seen nearly edge-on, also featuring a luminous core and thick bands of dust. Connecting the two galaxies is a prominent, turbulent bridge of reddish and brownish gas and dust, a twisted and stretched remnant left behind by their head-on collision.

A monochrome, face-on astronomical image of a grand-design spiral galaxy with a bright central nucleus and intricate, winding spiral arms set against a dark backdrop. Overlaid across the entire galaxy are dozens of green annotations. Each annotation consists of a small green circle with an adjacent green number. These numbered green markers are scattered throughout the galactic core, inner dust lanes, and outer star-forming regions, indicating specific targets or astronomical features for study.
A large, face-on spiral galaxy, IC 5332, dominates the left side of the image against the deep blackness of space. The galaxy features a glowing, compact yellow-white central core with delicate, feathery spiral arms winding gracefully outward. These symmetric arms are intricately laced with dark dust lanes and dotted with vibrant pink and purple clusters of active star formation. The surrounding background is densely populated by a "blizzard" of countless smaller, distant galaxies of various shapes, sizes, and brightnesses, alongside a few prominent, brilliant foreground stars.
