Planetary Nebula NGC 3699 in Centaurus | New Technology Telescope
This fetching cloud of gas was imaged by the European Southern Observatory Faint Object Spectrograph and Camera (EFOSC2) on its New Technology Telescope at the La Silla Observatory in Chile. It can be found nestled in the busy constellation of Centaurus in the skies of the southern hemisphere. The cloud of gas—named NGC 3699—is a planetary nebula. It is distinguished by an irregular mottled appearance and a dark rift that roughly bisects it.
Distance from Earth: ~5,000 light years
These objects, despite the name, have nothing to do with planets and are created in the final stages of the evolution of stars similar in mass to the Sun. The name "planetary nebula" arises from the time of their discovery by William Herschel, when they appeared in the telescopes of the time as rounded objects similar in looks to the planets.
Towards the end of their lives, stars like the Sun exhaust the supply of hydrogen in their cores, putting a stop to nuclear reactions. This causes the star's core to contract under the force of gravity and heat up, while the cooler outer layers expand tremendously—the surface of the Sun, for example, will likely engulf the orbit of Earth when it reaches this stage in its evolution. Unusually strong stellar winds push the gaseous outer layers of the star out into space, eventually exposing the core of the star, which begins to emit ultraviolet radiation, ionizing the expelled gas, causing the nebula's ethereal glow, and producing beautiful and varied sights, such as the one in this image.
NASA Astronaut Jessica Meir's Exercise Routine | International Space Station
Expedition 74 Flight Engineer and NASA Astronaut Jessica Meir: "Apologies for the background noise, life on International Space Station is loud! Without daily exercise on the ISS, we would lose significant muscle mass and bone density, since we don’t have the daily loading on our bodies that Earth’s gravitational environment provides.
We have the ARED 🏋️♀️ (Advanced Resistive Exercise Device), an engineering marvel that can be configured into a large number of weight lifting exercises, a cycle ergometer 🚲 (think a stationary bike with no handlebars and no seat—not needed in space!), and a treadmill. 🏃♀️
I started exercise right away, and it was so cool. Complete muscle memory! Really feels like I never left. Here’s a peek into our daily exercise routine!"

Polar-ring Galaxy NGC 660 in Pisces: Wide-field view | Mayall Telescope
This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. It shows NGC 660 and its surroundings. NGC 660 is a striking example of a polar ring galaxy.
Distance from Earth: ~40 million light-years
In the distant background are thousands of other galaxies. Nearly every small blue or yellow smudge is a very distant galaxy. A number of these, like NGC 660, show evidence of collisions or mergers. The image was generated with observations in the B (blue), V (green), I (orange) and Hydrogen-Alpha (red) filters. In this image, North is up, East is to the left.

Polar-ring Galaxy NGC 660 in Pisces | Subaru Telescope
NGC 660 is a polar ring galaxy located in the constellation Pisces. It features a large, extended ring structure surrounding the central spiral galaxy at a near-perpendicular angle. NGC 660 spans about 40,000 light years across. The ring emits blue light from active star-forming regions within it. The dark lanes in the ring and the galactic disk intersect, highlighting its complicated structure. This ring structure is thought to have been formed through the gravitational interaction of the central galaxy with another galaxy.

Polar-ring Galaxy NGC 660 in Pisces | Gemini North Telescope
This Gemini North telescope image captures the “bloody” aftermath of one galaxy piercing the heart of another. All the action appears in a single frame with the stunning polar-ring galaxy NGC 660 as the focus of attention. NGC 660 spans around 40,000 light years across and lies about 40 million light years distant in the direction of the constellation of Pisces. It has an unusually high gas content and resolves into hundreds of objects, a considerable fraction are blue and red supergiant stars.
The ring’s youngest detected stars formed only about seven million years ago, indicating a long and ongoing process of formation. As NGC 660’s ring is not truly polar, but inclined ~45˚ from the plane of the disk, it most likely formed by a previous interaction with a gas-rich galaxy about a billion years ago. That event would have stripped the interloper of its gas, directed it into NGC 660’s core, and triggered a furious burst of star formation. When the resulting short-lived, massive stars exploded shortly thereafter as supernovae, they would have generated shock waves that triggered more star formation, and so on, even to this day.
This image of the ring galaxy NGC 660, obtained with the Gemini Multi-Object Spectrograph on the Fredrick C. Gillett Gemini North telescope was obtained in August 2012. The image is made from three images taken through g, r, i, and hydrogen alpha filters and assigned the colors of blue, green, orange and red respectively in this color composite image. The field of view is 9.3x5.6 arcminutes and it is oriented 8 degrees clockwise from north at right and east up. The total exposure (integration) time was 1,620 seconds for all filters.

Lunar Eclipse & Aurora Borealis: Wide Views from Alaska
Astrophotographer Ayumi Yaegashi Bakken: ". . . more photos from the total lunar eclipse with the aurora near Coldfoot-Wiseman, Alaska. The sky was totally clear, and the aurora band showed up much earlier than the lunar eclipse. One incredible moment that occurred after 20-30 minutes from total eclipse was when the bright green band moved over the blood Moon. My cameras and my hands were cold enough to get frozen almost, but I will never forget this night."
Lunar eclipses occur at the full Moon phase. When Earth is positioned precisely between the Moon and Sun, Earth’s shadow falls upon the surface of the Moon, dimming it and sometimes turning the lunar surface a striking red over the course of a few hours. Each lunar eclipse is visible from half of Earth.

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.

China's Landspace: BF20 Engine Tests for Reusable Heavy Lift Commercial Rockets
🔥These high-thrust, long-duration engine tests by China commercial launch services provider Landspace lay the foundation for building a high-efficiency, reusable heavy-lift launch vehicle system. The full-flow staged combustion cycle (FFSC) BF20 220-ton-class methalox engine completed its first full-system test firing in May 2025. Since then it has undergone over 100 full-system ignition tests. This marks another milestone on their way to catch up with SpaceX's capabilities.
At the beginning of the Year of the Horse, LandSpace has fully resumed its R&D, production, and testing activities. Recently, the company successfully completed long-duration full-system hot-fire tests of its independently developed blue flame (BF) 20 LOX–methane FFSC engine demonstrating continued progress in the development of high-thrust, high-performance liquid rocket engines.
The BF engine is designed using the advanced FFSC cycle, combined with a highly integrated architecture and high chamber pressure design. It features two preburners: a fuel-rich preburner driving the fuel pump and an oxygen-rich preburner driving the oxidizer pump. The two gas streams are then routed into the main combustion chamber, where they burn completely to ensure optimal performance.
Compared with conventional engine cycles, the FFSC cycle offers higher propellant utilization efficiency, greater thrust-to-weight ratio, and longer service life. However, it also introduces significant engineering challenges, including high system coupling, structural complexity, multiple vibration sources, elevated internal pressures, and intense thermal loads.
Development of the BF engine has progressed rapidly. Since its first full-system hot-fire test in May 2025, it has accomplished more than 100 full-system ignition tests. The successful completion of this latest long-duration test demonstrates steady progress in key technology development and confirms LandSpace’s capability to carry out the complete development cycle of FFSC engines, supported by an agile testing and iteration approach.
These advances further improve the engine’s technical maturity and lay a solid foundation for future development. The BF engine will serve as a critical propulsion building block for the next generation of large to heavy-lift launch vehicles, supporting the development of high-efficiency and reusable heavy-lift propulsion systems.
Beijing-based LandSpace is a leading Chinese private space company. With its Zhuque-2 rocket, LandSpace became the world's first company to launch a methane-liquid oxygen rocket to Earth orbit in July 2023, ahead of U.S. rivals, including Elon Musk's SpaceX and Jeff Bezos' Blue Origin.

Paraselenic Circle and 22° Moon Halo: View from Yukon | Earth Science
Astrophotographer Joel Weatherly: "Last night . . . we were treated to an exceptional display of atmospheric optics, complete with paraselenae, a full paraselenic circle, and a 22° Halo around the Moon."
When sunlight or moonlight reflects or refracts from ice crystals in the atmosphere, an optical phenomenon collectively known as ‘halo’ is produced. When there are plenty of nearly vertical hexagonal ice crystals in the sky, the surfaces of the ice crystals will reflect moonlight like mirrors. A paraselenic circle will be produced if moonlight is reflected.
Yukon is a territory of Canada, bordering British Columbia to the south, the Northwest Territories to the east, the Beaufort Sea to the north, and the U.S. state of Alaska to the west. It is Canada's westernmost and smallest territory by land area.
