A wide-field astrophotograph of Messier 27, the Dumbbell Nebula, surrounded by a dense field of stars against a nearly black sky. The nebula is positioned near the center of the frame and appears as a softly glowing, irregular oval with two broad opposing lobes. Its brightest inner region is pale blue, cyan, and milky white, with translucent layers of gas overlapping around the faint central star. Curved reddish-pink arcs form parts of the outer shell, especially along the upper-left and lower-right edges, creating a rounded, expanding structure around the cooler blue interior. Fainter blue-green gas extends beyond the bright core as a diffuse halo. Hundreds of stars of different brightness fill the background, from tiny sharp points to several larger white stars with subtle four-point flares. Many stars show slight red and cyan fringes, adding small touches of color throughout the otherwise dark field. Captured with a Newton 130/900 telescope and a Sony A7S camera.

Several people walk through the open square, including one person pulling a blue suitcase. Two tall columns stand in the mist near the center, with statues on top. Birds fly overhead, and the distant background fades into dense fog.
Color photograph of a rural landscape at sunrise. A dirt path runs from the foreground into the distance on the left. A large leafless tree stands near the center, silhouetted against mist. The sun is low on the right side of the image, casting warm golden light across a grassy field. Low fog covers the background, with faint outlines of trees and hills beyond.
Black-and-white photo of a fisherman walking away along a rocky coastal path in the Algarve, Portugal. He wears a plaid shirt and cap, carries a woven basket in one hand, and holds fishing gear in the other.

This memorial marks a parachute insertion site used during World War II by agents of the British Special Operations Executive operating in southwestern France. It commemorates Percy Pink, who was parachuted into the countryside of Dordogne to assist and coordinate with the French Resistance. SOE agents were inserted by night aircraft into isolated rural areas such as this one, where resistance groups secured landing zones and helped recover parachuted personnel, radios, weapons, and supplies. Once on the ground, agents like Pink organized local maquis groups, coordinated sabotage against German transport and communications, and prepared resistance forces to assist Allied operations following the D-Day. The pink parachute symbol on the memorial represents the clandestine airborne insertion method used by SOE operatives. Such markers across rural France identify locations where agents landed or where resistance networks operated in support of the Allied campaign to liberate the country.

Time-lapse video of interstellar comet 3I/ATLAS recorded in 2025. The comet remains centered while background stars drift across the frame because the telescope is tracking the comet’s own motion, not Earth’s rotation. 3I/ATLAS was discovered by the ATLAS survey and is only the third confirmed object known to originate from outside the Solar System, following a hyperbolic, unbound trajectory. The video was captured with a 130/900 mm Newtonian telescope and a Sony A7S over 45 minutes using 10-second exposures stacked and aligned on the comet, revealing its motion relative to the star field.
Astrophotograph of interstellar comet 3I/ATLAS, first detected in 2025 by the ATLAS survey. 3I/ATLAS is special because it is only the third confirmed interstellar object ever observed passing through our Solar System. Its hyperbolic path shows it is not bound to the Sun’s gravity and will leave after this one-time visit. Capture details: 130/900 mm Newtonian + Sony A7S, 45 minutes total. The mount tracked to cancel Earth’s rotation. I shot 10 s frames and stacked them aligned on the comet, so the stars form trails from the comet’s motion against the background sky.
Railway tracks run beside a calm blue body of water under a wide blue sky with light clouds. Power lines follow the tracks into the distance, suggesting a long, quiet journey toward the horizon.
