Sights to See on Orbital Maneuvers | International Space Station

Sights to See on Orbital Maneuvers | International Space Station

Former Expedition 74 flight engineer Zena Cardman and NASA astronaut: "The International Space Station rarely makes big changes to its orientation, but we were lucky to experience such maneuvers (flipping around to fly butt-first, then flipping back again) before and after each SpaceX CRS-33 reboost. This 60x speed timelapse was one of my favorites since it captures a little of everything—sunset, lightning storms, air glow, moon glint, stars, and sunrise—as we did one (actually very slow) orbital cartwheel from Atlantic to Pacific."

Orion's Cradle: Stellar Nurseries

Orion's Cradle: Stellar Nurseries

Cradled in red-glowing hydrogen gas, stars are being born in Orion. These stellar nurseries lie at the edge of the giant Orion molecular cloud complex, some 1,500 light-years away. This detailed view spans about 12 degrees across the center of the well-known constellation, with the Great Orion Nebula, the closest large star-forming region, visible toward the lower right. The deep mosaic also includes, near the top center, the Flame Nebula and the Horsehead Nebula. Image data acquired with a hydrogen-alpha filter adds other remarkable features to this wide-angle cosmic vista: pervasive tendrils of energized atomic hydrogen gas and portions of the surrounding Barnard's Loop.

While the Orion Nebula and many stars in Orion are easy to see with the unaided eye, emission from the extensive interstellar gas is faint and much harder to record, even in telescopic views of the nebula-rich complex.

Planet Uranus: Auroral Activity | James Webb Space Telescope

Planet Uranus: Auroral Activity | James Webb Space Telescope

Uranus (January 2025)
Two bright auroral bands were detected near Uranus’s magnetic poles, together with reduced emission and ion density in part of the region between the two bands (a feature likely linked to transitions in magnetic field lines).
Uranus collage (January 2025, labeled version)

For the first time, an international team of astronomers have mapped the vertical structure of Uranus’s upper atmosphere, uncovering how temperature and charged particles vary with height across the planet. Using Webb’s NIRSpec instrument, the team detected the faint glow from molecules high above the clouds. These unique data provide the most detailed portrait yet of where the planet’s auroras form, how they are influenced by its unusually tilted magnetic field, and how Uranus’s atmosphere has continued to cool over the past three decades. The results offer a new window into how ice-giant planets distribute energy in their upper layers.

L2 is one of the so-called Lagrangian points, discovered by mathematician Joseph Louis Lagrange. Lagrangian points are locations in space where gravitational forces and the orbital motion of a body balance each other. Therefore, they can be used by spacecraft to 'hover'. L2 is located 1.5 million kilometers directly 'behind' the Earth as viewed from the Sun. It is about four times further away from the Earth than the Moon ever gets and orbits the Sun at the same rate as the Earth.

It is a great place observe the larger Universe. A spacecraft would not have to make constant orbits of the Earth that result in it passing in and out of the Earth's shadow and causing it to heat up and cool down, distorting its view. Free from this restriction and far away from the heat radiated by Earth, L2 provides a much more stable viewpoint.

Planet Uranus: Auroral Activity Time-lapse Rotation | James Webb Space Telescope

This timelapse video is believed to be the only dataset to date that has continuously observed a full rotation of Uranus by a single telescope, facilitated by Webb’s uniquely positioned orbit at L2 that observed the planet for approximately 17 hours. This time-lapse video consists of over 1200 slices of multi-object spectroscopy data. These observations provide the most detailed view to date of Uranus’ vertical upper atmosphere, showing where temperatures and ion densities peak, and revealing clear auroral structures shaped by the planet’s unusual magnetic field.

Shenzhou-21 Astronauts Grow Cherry Tomatoes | China Space Station

Shenzhou-21 Astronauts Grow Cherry Tomatoes | China Space Station

Chinese astronauts could be set to enjoy an upgraded diet in the future as the crew members of the Shenzhou-21 mission get ready to reap a bountiful harvest of freshly-grown tomatoes from their very own in-orbit vegetable garden aboard the Tiangong Space Station.

Amid the ongoing Spring Festival holiday, when millions of Chinese gather for family reunions and enjoy grand festive dinners to welcome the Chinese New Year back on Earth, the astronauts in space may soon be able to tuck into some tasty foods of their own, as their prized tomatoes enter their ripe season.

The three crew members had already enjoyed something of a first in space when they indulged in a special space barbecue after bringing a hot-air oven to space back in November 2025, sharing in a mouthwatering meat feast with the predecessor crew of Shenzhou-20 during their brief handover period aboard the space station.

Now, however, they are focusing their efforts on healthier ingredients. So far, ten batches of seven plant species, including lettuce, cherry tomatoes and sweet potatoes, have been cultivated at the space station, providing astronauts with more fresh fruits and vegetables and the chance for a much more balanced nutritional intake during their six-month-long mission.

Astronaut Zhang Hongzhang introduced the unique  looking contraption that is being used to carefully cultivate cherry tomatoes.

"This tomato cultivation device is called 'water aeroponic cultivation' and was developed by a research team from the China Astronaut Research and Training Center (CARTC). It can significantly increase the utilization rate of water through water evaporation. On the other hand, an LED spectrum has been specially customized, that can significantly improve the efficiency of energy utilization. As a result, we can see a thriving picture of space tomatoes growing," said Zhang.

The cultivation device was delivered to the space station by the Tianzhou-9 cargo craft in July last year. It is mainly used to verify key technologies for efficient plant aeroponic cultivation in a microgravity environment.

"Currently in orbit, we take care of it and record its growing data every day. While providing valuable planting data in orbit, it will be of very good reference value to the cultivation of space crops in later missions," said astronaut Wu Fei.

Relying on the cultivation device, researchers can systematically carry out research on multiple subjects, such as in-orbit efficient plant cultivation, fruit and vegetable production and evaluation in space, atmospheric regeneration capacity and efficiency, and in-orbit plant care models.

The aeroponic cultivation experiments are also planned to be carried out on wheat, carrots and medicinal and edible plants in the future.

Launched into space on October 31 last year, the Shenzhou-21 crew is now over 100 days into its six-month space mission. All tasks including scientific experiments, equipment maintenance and health management are progressing smoothly, according to China's space agency—the China National Space Administration (CNSA).

How NASA's Perseverance Mars Rover Learned to ‘Self-Locate’ | JPL

How NASA's Perseverance Mars Rover Learned to ‘Self-Locate’ | JPL


NASA’s Perseverance rover can now precisely determine its own location on Mars without waiting for human help from Earth. This is possible thanks to a new technology called Mars Global Localization.

This technology rapidly compares panoramic images from the rover’s navigation cameras with onboard orbital terrain maps. It is done with an algorithm that runs on the rover’s Helicopter Base Station processor that was originally used to communicate with the Ingenuity Mars Helicopter. In a few minutes, the algorithm can pinpoint Perseverance’s position to within about 10 inches (25 centimeters). The technology will help the rover drive farther autonomously and keep exploring. 

Mars Global Localization was first used successfully for regular mission operations on Feb. 2, 2026, and the team expects related reliability techniques to inform future missions, including exploration on the Moon.

"Dark Galaxy" CDG-2 Detected in Perseus | Hubble Space Telescope



The low-surface-brightness galaxy CDG-2, shown in this image from the NASA/European Space Agency Hubble Space Telescope, is dominated by dark matter and contains only a sparse scattering of stars. This galaxy is nearly invisible, but by using advanced statistical techniques, scientists identified it by searching for tight groupings of stars called globular clusters at the center of this image.

The Hubble observations include those from programme 15235 (W. Harris).

"Dark Galaxy" CDG-2 Detected in Perseus | Hubble Space Telescope

"Dark Galaxy" CDG-2 Detected in Perseus | Hubble Space Telescope

The NASA/European Space Agency Hubble Space Telescope has revealed an exceptional discovery in the Perseus galaxy cluster—CDG-2, an ultra-low surface brightness galaxy composed of 99% dark matter.

This elusive galaxy remained hidden until astronomers detected a slight increase in globular cluster density, suggesting the presence of an underlying galactic structure. 

Observations from Hubble, European Space Agency's Euclid observatory, and the Subaru Telescope confirmed a faint halo of diffuse light surrounding these ancient star clusters.

Analysis indicates CDG-2 has the luminosity of approximately six million Sun-like stars with the clusters comprising about 16% of its visible matter. The galaxy's normal matter was likely stripped away through gravitational interactions within the Perseus cluster.

This discovery provides a rare opportunity to study dark matter's fundamental properties and how it shapes galactic evolution across the universe.

Galaxy NGC 6240 in Ophiuchus | Victor Blanco Telescope

Galaxy NGC 6240 in Ophiuchus | Victor Blanco Telescope


A detailed image of NGC 6240 taken by the Dark Energy Camera (DECam). DECam was made by the U.S. Department of Energy (DOE) and is mounted on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of the National Science Foundation (NSF) NOIRLab.

NGC 6240 lies 400 million light-years away in the constellation of Ophiuchus (The Serpent Holder). This galaxy has an elongated shape with branching wisps, loops, and tails. This mess of gas, dust, and stars bears more than a passing resemblance to a butterfly and, though perhaps less conventionally beautiful, a lobster.

This bizarrely-shaped galaxy did not begin its life looking like this. Its distorted appearance is a result of a galactic merger that occurred when two galaxies drifted too close to one another. This merger sparked bursts of new star formation and triggered many hot young stars to explode as supernovae. A new supernova was discovered in this galaxy in 2013, named SN 2013dc. 

At the center of NGC 6240 an even more interesting phenomenon is taking place. When the two galaxies came together, their central black holes did so, too. There are two supermassive black holes within this jumble, spiraling closer and closer to one another. They are currently only around 3,000 light-years apart, incredibly close given that the galaxy itself spans 300,000 light-years. This proximity secures their fate as they are now too close to escape each other and will soon form a single immense black hole.

Aurora over Alaska

Aurora over Alaska





Also known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.

Alaska is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is considered to be the northernmost, westernmost, and easternmost state in the United States. It borders the Canadian territory of the Yukon and the province of British Columbia to the east. It shares a western maritime border in the Bering Strait with Russia. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south.

The Fellowship of The Telescopes: Narrated by John Rhys-Davies | NASA Goddard

The Fellowship of The Telescopes: Narrated by John Rhys-Davies | NASA Goddard

For centuries, humanity has looked to the stars and wondered what lies beyond the veil of night. Once, our eyes were our only instruments, but today, our reach extends across the cosmos. From the Hubble Space Telescope’s steadfast watch to the James Webb Space Telescope’s golden gaze, we have built machines that see the unseen, unraveling the secrets written in starlight.

Each telescope is a sentinel in the void, Hubble, Webb, the upcoming Nancy Grace Roman Space Telescope, and not too long from now, the Habitable Worlds Observatory, each revealing new chapters of the universe’s story. Together, they form a fellowship of discovery, driven by the minds and hearts of those who dare to look deeper, to ask what else is out there.

Narrated by the legendary John Rhys-Davies, this film is a tribute to exploration, to science, and to the boundless curiosity that defines us. The Fellowship of the Telescopes endures, lighting the way toward the next great frontier.

https://youtu.be/ZyVi21IuBro

Despite being far from home, astronauts aboard China's Tiangong Space Station on February 16, 2026, spent the Chinese New Year's Eve with their own festive party in orbit.

The Chinese New Year begins with the Spring Festival that falls on Tuesday this year. This year ushers in a Year of the Horse, the seventh of the 12 animals in the Chinese zodiac.

In the beautifully decorated space station adorned with red lanterns, Chinese knots, and paper-cut crafts, the Shenzhou-21 trio presented a variety of performances. They played the mouth organ, engaged in clapper talk, and sang the song "The Five-Starred Red Flag Flies in Space," expressing their joy on the Chinese New Year's Eve. They concluded their show with a heartfelt poetry recitation.

During the nine-day official Spring Festival holiday season, aside from two days of regular days off, the three astronauts will continue with their scheduled work for the remaining time. They will successively complete various in-orbit experiments, and conduct cabin environment organization, platform maintenance, and so on.

Launched on October 31, 2025, the Shenzhou-21 crew is in a six-month space journey that has already exceeded 100 days. According to China's space agency—China National Space Administration, all tasks, including scientific experiments, equipment maintenance, and health management, are progressing smoothly.

For the astronauts, physical exercise is an important part of their routine.

"Besides the popular treadmill, bicycle, and resistance training equipment, the Astronaut Center of China has also designed a core muscle training device for us, which I am currently using. I will use this device for core strength training, starting with the first exercise: the crunch. I hope everyone will put in the effort in the new year to strive for a happy life. Now I will proceed to the second exercise: the overhead press. I wish everyone in the new year to elevate their happy lives to new heights," said astronaut Wu Fei.
