Sharp detail from NASA’s Hubble Space Telescope brings every feature of NGC 1266 into clear view. Dust lanes in shades of reddish brown stretch across the galaxy’s flattened disk and weave around a bright central bulge. Hints of spiral structure linger in the disk even though no obvious arms stand out. Tiny clumps and filaments of dust partly hide the core while distant background galaxies shine through the outer haze in red, blue, and orange tones against the black of space.
Engineers at NASA’s Jet Propulsion Laboratory sent a short email last February. Its subject line read simply “Hello Universe.” The message came straight from a new processor now moving through a full round of checks for deep-space work. Space computers have operated under tight limits for decades. Radiation from the sun and deep space can scramble data, while temperature swings and launch forces demand parts that stay reliable for years without any chance of repair. Designers long relied on proven but slow chips to avoid sudden shutdowns that leave a vehicle drifting until ground teams step in.
In the frame, NASA’s six-wheeled Perseverance rover is securely planted on a stretch of dirt far to the west of Jezero Crater. You can see its mast dipping down towards Arethusa, the rocky protrusion we’ve all become familiar with, before swinging back around to face the camera full on. Years of driving have created a fine layer of dust on the rover and its wheels, catching the light and creating a beautiful warm glow. Meanwhile, a new circular mark on Arethusa indicates where the rover dug in with its biters and removed a portion of the surface to examine what was hidden beneath. The robotic arm in front, with the WATSON camera attached to its end, is the one that took it all in.
Last month, NASA astronaut Chris Williams floated aboard the Crew Dragon Freedom, pointing his camera out the window. What he photographed shows our planet enveloped in a delicate ribbon of light, called airglow, with the Milky Way arching overhead like a faint road through the stars. The photograph, shot on April 13 while the spacecraft was docked to the International Space Station, provides a clear view of something that occurs high above us every night.

Astronomers released an image this week that pulls viewers straight into the dynamic core of Messier 77 (M77). Located 45 million light-years away in the constellation Cetus, this barred spiral galaxy offers a clear target for study thanks to its relative closeness and the range of activity packed inside its structure. Captured entirely in mid-infrared light by the James Webb Space Telescope’s specialized instrument, the view highlights details that ordinary light cannot reach.
NASA’s Curiosity had spent years gradually ascending the slopes of Mount Sharp inside Gale Crater. On April 25, the rover drilled into a rock known as Atacama, which was about a foot and a half across and six inches thick, weighing over thirty pounds. The drill sank in neatly enough to collect the sample the scientists need. The rover then pulled its arm back. The entire rock came with it.

Landsat 8, owned and operated by the USGS, captured the image on February 11, during the brief Antarctic summer. The satellite’s Operational Land Imager captured a view from orbit of Peter I Island in the Bellingshausen Sea, which is located at 68.86 degrees south latitude. The site, which is 400 kilometers off the coast of West Antarctica and more than 1,800 kilometers from the nearest point in Chile, feels inconceivably remote.
Back in 2015, Marcelo de Oliveira Souza was at his desk in Brazil, staring at a computer screen with some rather long numbers regarding near-Earth asteroids flashing by. He was making preliminary predictions of the courses these space objects would take, to help people determine whether they would pose a threat to our world. One in particular drew his attention, 2001 CA21, because the first calculations showed an orbit that virtually sliced straight through between Earth and Mars in a way nobody had picked up on before.
NGC 3137 is a spiral galaxy located 53 million light-years away in the constellation Antlia, and the Hubble Space Telescope has captured it in exquisite clarity. It captured images of this galaxy at six different wavelengths, enabling astronomers to combine ultraviolet, visible, and hydrogen emission data into a single complete picture. At first impression, the image is beautiful, with the galaxy dominating the frame at a sharp angle and its loose arms fanning out like feathers in a summer wind. The older stars in the galaxy’s center have a warm golden tone, whilst the hotter, younger groups of stars on the periphery appear pale blue.

On April 14, video footage captured NASA’s X-59 silent supersonic research aircraft speeding through the skies over California’s Mojave Desert. Lockheed Martin built the jet, which has a needle-shaped nose and an engine located high on its back. It is nearly 100 feet long and has a wingspan of little under 30 feet. Engineers published the recording as part of an update to the QueSST program, which aims to enable supersonic travel over land by reducing the thunderous boom into a soothing thud.
