Shenzhou-20 Astronauts Complete Fourth Spacewalk | China Space Station

Shenzhou-20 Astronauts Complete Fourth Spacewalk | China Space Station

The Shenzhou-20 crew aboard China's orbiting space station completed their mission's fourth spacewalk early on September 26, 2025, according to the China Manned Space Agency (CMSA).

The astronaut trio—Chen Dong, Chen Zhongrui and Wang Jie—worked outside the space station for approximately six hours and accomplished all assigned tasks at 01:35 Beijing Time, assisted by the Tiangong space station's robotic arm and a ground control team.

Chen Zhongrui and Wang Jie, tasked with conducting the spacewalk operations, finished the installation of debris protection devices and the inspection and maintenance of external equipment, according to the CMSA.

This is the first time a spacewalk has been performed by two astronauts from China's third group of astronaut recruits.

Up to now, the Shenzhou-20 astronauts have completed four extravehicular activities, making it one of the Chinese crews that have carried out the most spacewalks aboard the orbiting space station.

The crew has stayed in orbit for more than 150 days, carrying out a large number of scientific experiments and technological tests.

The Shenzhou-20 astronauts entered the space station on April 25 for a mission expected to last around 6 months.

Equinox Auroras over Tromsø, Norway

Equinox Auroras over Tromsø, Norway




Photographer Markus Varik: " . . . nothing comes close to, what we witnessed yesterday. It was unfortunately super cloudy around Tromsø, but the weather forecast said, there should be openings here and there later on in the evening. In reality, there was more rain and clouds and there were periods, where we were just sitting under cold freezing rain for elongated periods of time. But when it mattered, the sky cleared up. The variety of different colors was just insane . . ."

The equinox marks the exact moment when the center of the Sun crosses the plane of a planet’s equator. 

The aurora borealis, also known as the northern lights, occurs in an upper layer of Earth’s atmosphere called the ionosphere, but they typically originate with activity on the Sun. Occasionally, during explosions called coronal mass ejections, the Sun releases charged particles that speed across the solar system.

Auroras are produced when the Earth's magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. [Wikipedia]

Solid Colored Aurora
Green is common at the upper latitudes, while red is rare. On the other hand, aurora viewed from lower latitudes tend to be red.

Element Emission Colors
Oxygen: The big player in the aurora is oxygen. Oxygen is responsible for the vivid green (wavelength of 557.7 nm) and also for a deep brownish-red (wavelength of 630.0 nm). Pure green and greenish-yellow aurorae result from the excitation of oxygen.

Nitrogen: Nitrogen emits blue (multiple wavelengths) and red light.

Other Gases: Other gases in the atmosphere become excited and emit light, although the wavelengths may be outside of the range of human vision or else too faint to see. Hydrogen and helium, for example, emit blue and purple. Although our eyes cannot see all of these colors, photographic film and digital cameras often record a broader range of hues.

Aurora Colors According to Altitude
Above 150 miles: red, oxygen
Up to 150 miles: green, oxygen
Above 60 miles: purple or violet, nitrogen
Up to 60 miles: blue, nitrogen

NASA's Orion Spacecraft: How the Launch Abort System for Crew Safety Works

NASA's Orion Spacecraft: How the Launch Abort System for Crew Safety Works

"On launch day, every element of Orion is poised for purpose. Among the most important is the Launch Abort System (LAS)—a slender tower mounted above the crew module, ready to provide astronauts with a swift and controlled escape, if the mission requires it. The LAS is always on watch, standing guard from the moment the crew boards Orion and the hatch is closed. Should it be called into action, it can respond in milliseconds—whether on the launch pad or during ascent—separating the spacecraft from its rocket, guiding it to a safe trajectory and clearing the way for a return to Earth."

The upcoming Artemis II test flight will send NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and Canadian Space Agency (CSA) astronaut Jeremy Hansen around the Moon and return them safely back home.

The Artemis II crew will be sent on a ten-day Moon journey no earlier than April 2026.

A SpaceX Falcon 9 rocket successfully launched and deployed NASA’s Interstellar Mapping and Acceleration Probe (IMAP), the agency’s Carruthers Geocorona Observatory, and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On–Lagrange 1 (SWFO-L1) spacecraft. Launch took place on schedule at 7:30 a.m. EDT, Wednesday, Sept. 24, 2025, from Launch Complex 39A at NASA's Kennedy Space Center in Florida. 

The missions will each focus on different effects of the solar wind—the continuous stream of particles emitted by the Sun—and space weather—the changing conditions in space driven by the Sun—from their origins at the Sun to their farthest reaches billions of miles away at the edge of our solar system. 

The Interstellar Mapping and Acceleration Probe (IMAP) will explore and map the heliosphere—the invisible cosmic shield surrounding our solar system—to answer great unknowns about how particles accelerate in the solar wind.


NASA’s Carruthers Geocorona Observatory is a small satellite that will observe Earth’s outermost atmospheric layer, the exosphere. It will image the faint glow of ultraviolet light from this region, called the geocorona, to better understand how space weather impacts our planet. The Carruthers mission continues the legacy of the Apollo era, expanding on measurements first taken during Apollo 16.

The SWFO-L1 spacecraft will monitor space weather and detect solar storms in advance, serving as an early warning beacon for potentially disruptive space weather, helping safeguard Earth’s critical infrastructure and technological-dependent industries. The SWFO-L1 spacecraft is the first NOAA observatory designed specifically for and fully dedicated to continuous, operational space weather observations.

Planet Earth Aerosols: Inside the Visualization | NASA Goddard

Planet Earth Aerosols: Inside the Visualization | NASA Goddard

NASA uses satellites, ground measurements, and powerful computer models to track tiny particles floating in our air called aerosols. These small particles can travel thousands of miles, affecting the air we breathe and how far we can see, even far from where they originated. This visualization shows how these particles moved through Earth's atmosphere between August 1 and September 14, 2024.

Each color represents a type of aerosol: sea salt (blue), dust (pink/magenta), smoke from fires (orange/red), and sulfates from pollution and volcanoes (green). This visualization is based on NASA's Goddard Earth Observing System (GEOS) model. It provides realistic, high-resolution weather and aerosol data that enables customized environmental prediction and advances in artifical intelligence (AI) research.

Stellar Nursery Sagittarius B2: MIRI versus NIRCam Views | Webb Telescope

Stellar Nursery Sagittarius B2: MIRI versus NIRCam Views | Webb Telescope

This video shows two views of a colorful array of massive stars and glowing cosmic dust in the Sagittarius B2 (Sgr B2) molecular cloud, the most massive and active star-forming region in our Milky Way galaxy.

The first image shown is Webb’s mid-infrared instrument (MIRI) view of the Sgr B2 region in mid-infrared light with warm dust glowing brightly. To the right is one clump of clouds that captured astronomers’ attention. It is redder than the rest of the clouds in the image and corresponds to an area that other telescopes have shown to be one of the most molecularly rich regions known. 

The second image shown is the molecular cloud glow in near-infrared light, captured by Webb’s near-infrared camera (NIRCam). In this light, astronomers see more of the region’s diverse, colorful stars, but less of its gas and dust structure.

Only the brightest stars in this region emit mid-infrared light that can be picked up by Webb’s MIRI instrument. This is why the first image has so many fewer stars than that captured by Webb’s NIRCam in the second image.

Stars, gas and cosmic dust in the Sagittarius B2 molecular cloud glow in near-infrared light, captured by Webb’s near-infrared camera (NIRCam). In this light, astronomers see more of the region’s diverse, colorful stars, but less of its gas and dust structure. Webb’s instruments each provide astronomers with important information that help build a more complete picture of what is happening in this intriguing portion of the center of our galaxy. 

Sagittarius B2 (Sgr B2) is located about 390 light years from the center of the Milky Way. This complex is the largest molecular cloud in the vicinity of the core and one of the largest in the galaxy, spanning a region about 150 light years across. The total mass of Sgr B2 is about 3 million times the mass of the Sun.

Sagittarius B2 is located only a few hundred light-years from the supermassive black hole at the heart of the galaxy called Sagittarius A*, a region densely packed with stars, star-forming clouds, and complex magnetic fields. The infrared light that Webb detects is able to pass through a portion of the area’s thick clouds to reveal young stars and the warm dust surrounding them. Astronomers think that analysis of Webb’s data will help unravel enduring mysteries of the star formation process, and why Sagittarius B2 is forming so many more stars than the rest of the galactic center.

However, one of the most notable aspects of Webb’s images of Sagittarius B2 are the portions that remain dark. These ironically empty-looking areas of space are actually so dense with gas and dust that even Webb cannot see through them. These thick clouds are the raw material of future stars and a cocoon for those still too young to shine.

It will image the faint glow of ultraviolet light from this region, called the geocorona, to better understand how space weather impacts our planet. The Carruthers mission continues the legacy of the Apollo era, expanding on measurements first taken during Apollo 16.

The SWFO-L1 spacecraft will monitor space weather and detect solar storms in advance, serving as an early warning beacon for potentially disruptive space weather, helping safeguard Earth’s critical infrastructure and technological-dependent industries. The SWFO-L1 spacecraft is the first NOAA observatory designed specifically for and fully dedicated to continuous, operational space weather observations.
