Shenzhou-20 Crew Parachute Landing in Shenzhou-21 Capsule | China Space Station
Shenzhou-21 Spacecraft Undocking Before Crew's Earth Return | China Space Station
China's Shenzhou-21 crewed spacecraft undocked from the space station combination at 11:14 on November 14, 2025, (Beijing Time) to send the Shenzhou-20 astronauts back to Earth, according to the China Manned Space Agency (CMSA).
The return capsule of the Shenzhou-21 spacecraft, carrying the Shenzhou-20 astronauts Chen Dong, Chen Zhongrui and Wang Jie, touched down at the Dongfeng landing site in north China's Inner Mongolia Autonomous Region on Friday, safely taking the three-member crew back home.
During a talk program of the China Media Group (CMG), Zhou Yaqiang, a technology official from the China Manned Space Agency (CMSA), explained the reasons for using the Shenzhou-21 instead of launching a new spacecraft to take the astronauts back to Earth.
"There are two main factors. First, the technical specifications of the Shenzhou-21 spacecraft are consistent with those of the Shenzhou-20 spacecraft, and the Shenzhou-20 crew had previously undergone trainings on the Shenzhou-21 spacecraft, making them quite familiar with it. In contrast, the instruments on the Shenzhou-22 spacecraft have been optimized and improved. Second, the Shenzhou-20 crew had completed their scheduled in-orbit missions, and we wanted to bring them back to the Earth as quickly as possible. Ultimately, it was all to ensure the return mission is flawless and that the astronauts are absolutely safe," said Zhou.
Li Guangsu, an astronaut from the Shenzhou-18 crewed mission, provided insight into the preparations Shenzhou-20 crew made for a safe and comfortable return aboard the Shenzhou-21 spacecraft.
"For astronauts, the process of returning aboard a different spacecraft this time involves transferring relevant materials from the Shenzhou-20 spacecraft to the Shenzhou-21 spacecraft. Another crucial task is replacing the seat cushions on the Shenzhou-21 spacecraft, as these cushions are custom-made to fit each astronaut's individual measurements," Li said.
The Shenzhou-20 crew was sent into space from the Jiuquan Satellite Launch Center in northwest China on April 24.
Their return, originally scheduled for Nov. 5, was postponed due to a suspected impact to the Shenzhou-20 spacecraft from tiny space debris, according to the CMSA.
In response, emergency protocols were immediately activated, and a comprehensive simulation analysis, testing and safety assessment of the Shenzhou-20 crewed spacecraft were conducted to determine the safest course for the astronauts' return.
Following the review, the CMSA announced that the Shenzhou-20 spacecraft no longer meets the stringent safety standards required for re-entry. As a result, it will remain in orbit to continue the relevant experiments.
Next, the Shenzhou-22 spacecraft will be launched at an appropriate time, said the CMSA.

NASA's ESCAPADE Mission Investigates Mars Space Weather for Human Explorers
NASA’s new ESCAPADE mission is launching to Mars to help us better understand the Sun’s influence on Mars’ past and present. Its work could help protect future human explorers from potentially dangerous space weather when they set foot on the Red Planet.
For the first time, the mission will use two identical spacecraft to investigate how the solar wind interacts with Mars’ magnetic environment and how this interaction drives the planet’s atmospheric escape. Its observations will reveal the planet’s real-time response to space weather and how the Martian magnetosphere changes over time.
The ESCAPADE orbiters build on earlier Mars missions, such as NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) orbiter. The MAVEN mission has one spacecraft that has been studying Mars’ atmospheric loss since arriving at the Red Planet in 2014.
ESCAPADE is scheduled to launch this month aboard a Blue Origin New Glenn rocket from Cape Canaveral in Florida.

Aurora over North Dakota
Photographer Lyndon Anderson: "Best viewing in quite some time. The photo that has orange colors, it was taken looking south as the auroral oval had moved south of my location. The colors were different from all my other photos due to possibly green and red blending some in the different levels of the atmosphere."

What’s the True Shape of a Supernova? | European Southern Observatory
Astronomers have observed a supernova just a day after it was first detected. In the early stages of the blast, the explosion has not yet interacted with the material around the star, retaining its true shape. This initial shape has now been revealed for the first time. This video summarises the discovery.
Swift observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed the explosive death of a star just as the blast was breaking through the star’s surface. For the first time, astronomers unveiled the shape of the explosion at its earliest, fleeting stage. This brief initial phase would not have been observable a day later and helps address a whole set of questions about how massive stars go supernova.
When the supernova explosion SN 2024ggi was first detected on the night of April 10, 2024 local time, Yi Yang, an assistant professor at Tsinghua University in Beijing, China, and the lead author of the new study, had just landed in San Francisco after a long-haul flight. He knew he had to act quickly. Twelve hours later, he sent an observing proposal to the European Southern Observatory (ESO). After a very quick approval process, the VLT telescope in Chile was pointed at the supernova on April 11, 2024, just 26 hours after the initial detection.
SN 2024ggi is located in the galaxy NGC 3621 in the direction of the constellation Hydra ‘only’ 22 million light-years away, close by in astronomical terms. With a large telescope and the right instrument, the international team knew they had a rare opportunity to unravel the shape of the explosion shortly after it happened. “The first VLT observations captured the phase during which matter accelerated by the explosion near the center of the star shot through the star’s surface. For a few hours, the geometry of the star and its explosion could be, and were, observed together,” says Dietrich Baade, an ESO astronomer in Germany, and co-author of the study published today in Science Advances.
“The geometry of a supernova explosion provides fundamental information on stellar evolution and the physical processes leading to these cosmic fireworks,” Yang explains. The exact mechanisms behind supernova explosions of massive stars, those with more than eight times the mass of the Sun, are still debated and are one of the fundamental questions scientists want to address. This supernova’s progenitor was a red supergiant star, with a mass 12 to 15 times that of the Sun and a radius 500 times larger, making SN 2024ggi a classical example of a massive-star explosion.
We know that during its life a typical star keeps its spherical shape as a result of a very precise equilibrium of the gravitational force that wants to squeeze it and the pressure of its nuclear engine that wants to expand it. When it runs out of its last source of fuel, the nuclear engine starts sputtering. For massive stars this marks the beginning of a supernova: the core of the dying star collapses, the mass shells around fall onto it and bounce off. This rebound shock then propagates outward, disrupting the star.
Once the shock breaks through the surface, it unleashes immense amounts of energy—the supernova then brightens dramatically and becomes observable. During a short-lived phase, the supernova’s initial ‘breakout’ shape can be studied before the explosion interacts with the material surrounding the dying star.
This is what astronomers have now achieved for the very first time with ESO's VLT, using a technique called ‘spectropolarimetry’. “Spectropolarimetry delivers information about the geometry of the explosion that other types of observation cannot provide because the angular scales are too tiny,” says Lifan Wang, co-author and professor at the Texas A&M University in the US, who was a student at ESO at the start of his astronomy career. Even though the exploding star appears as a single point, the polarization of its light carries hidden clues about its geometry, which the team were able to unravel.
The only facility in the southern hemisphere capable of capturing the shape of a supernova through such a measurement is the FORS2 instrument installed on the VLT. With the FORS2 data, the astronomers found that the initial blast of material was shaped like an olive. As the explosion spread outwards and collided with the matter around the star, the shape flattened but the axis of symmetry of the ejecta remained the same. "These findings suggest a common physical mechanism that drives the explosion of many massive stars, which manifests a well-defined axial symmetry and acts on large scales,” according to Yang.
With this knowledge astronomers can already rule out some of the current supernova models and add new information to improve other ones, providing insights into the powerful deaths of massive stars. "This discovery not only reshapes our understanding of stellar explosions, but also demonstrates what can be achieved when science transcends borders,” says co-author and ESO astronomer Ferdinando Patat. “It’s a powerful reminder that curiosity, collaboration, and swift action can unlock profound insights into the physics shaping our Universe."

Crash of the Galactic Titans: Milky Way & Andromeda Collision in ~4 Billion Years
In about 4 billion years, the Milky Way and Andromeda galaxies will collide.
The three largest galaxies in our Local Group of Galaxies are our Milky Way along with the Andromeda (also known as Messier 31) and Triangulum (also known as Messier 33) galaxies. This scientific visualization of a computer simulation depicts their joint evolution over the next several billion years and features the inevitable massive collision between the Milky Way and Andromeda. Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together in a head-on collision about 4 billion years from now. The thin disk shapes of these spiral galaxies are strongly distorted and irrevocably transformed by the encounter. Around 6 billion years from now, the two galaxies will merge to form a single elliptical galaxy. The Triangulum galaxy continues to orbit the merged pair through the end of this computer simulation, though other computer models show it becoming part of the collision.
The visualization covers 8.2 billion years into the future at 105 million years per second. Colors are representative: light blue for spiral galaxies (considered "blue" in astronomy parlance because of their active star formation) and orange-yellow for elliptical galaxies (called "red" by astronomers for their old stellar populations). A random background field of galaxies has been added to the simulation in order to indicate the camera motion through the simulation volume.
This visualization depicts the same simulation as the "Future Galaxy Merger" visualization, but includes the Triangulum galaxy and utilizes a more cinematic camera choreography.
