Astronauts welcome arrival of new crewmates | On the International Space Station this week Nov. 24-28, 2025

A recent study suggests that a massive supernova explosion may have led to the formation of a binary black hole, providing new insights into the evolutionary history of massive stars. This finding highlights the complex processes involved in stellar evolution and the eventual creation of black holes.

NASA's X-ray instrument has discovered that black holes behave like 'cosmic seesaws,' influencing the dynamics of their accretion flows in a manner described as an energetic tug-of-war. This finding sheds light on the complex interactions occurring within black holes and their surroundings.

Recent findings suggest that ancient lakes on Mars developed ice shields to maintain warmth, potentially explaining how liquid water persisted on the planet despite a colder climate. This discovery sheds light on Mars' hydrological history and its capacity to support water in various forms.

NASA is returning four astronauts from the International Space Station (ISS) earlier than planned due to a medical concern affecting one of the Crew-11 astronauts. This decision marks the first-ever medical evacuation from the ISS, highlighting the agency's commitment to crew safety. The astronauts are expected to return to Earth soon, following the agency's protocols for such emergencies.

A recent satellite image captured snowy peaks in Greenland, highlighting the region's significant influence on local climate patterns. This observation underscores the ongoing changes in the Arctic environment as climate dynamics evolve.

SpaceX's Crew-11 astronauts are set to undock from the International Space Station (ISS) today, marking the first-ever medical evacuation from the orbiting laboratory due to an undisclosed medical issue affecting one of the crew members. This unprecedented event will be broadcast live, allowing viewers to witness the historic moment.

On January 14, 2026, SpaceX's Crew-11 mission will conduct the first-ever medical evacuation from the International Space Station (ISS), returning four astronauts to Earth due to a medical concern affecting one of the crew members. This unprecedented event highlights the challenges faced by astronauts in space and the importance of health monitoring in such extreme environments.

Research indicates that viruses may exhibit enhanced capabilities in the microgravity environment of the International Space Station (ISS), suggesting that microgravity influences viral evolution in ways that remain largely unexplored.
