'Backward and upward and tilted': Spaceflight causes astronauts' brains to shift inside their skulls

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.

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.

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.

Astronomers are observing the red giant star R Leonis as it exhibits an increasingly rapid dimming and brightening pattern, signaling the potential end of its life cycle. This phenomenon, described as the star's 'heartbeat,' has been monitored for over two centuries, and recent changes suggest a messy demise may be imminent.

Astronomers have made a groundbreaking discovery involving a mysterious shockwave surrounding a dead star, which has produced a spectacular nebula. This unexpected phenomenon challenges previous assumptions about discless systems in space, leading to a rare moment of astonishment within the scientific community.

Satellite imagery has revealed that Iceberg A23-A, which has existed since the Chernobyl disaster and the Space Shuttle Challenger accident, is now melting and turning blue, indicating significant environmental changes.
