NASA's IXPE mission has provided new insights into black holes' coronae, revealing their shape and enhancing our ...

For the deepest vertical pit cave in the world, head to Slovenia near the border with Italy. Vrtiglavica, found in the Kanin ...

Researchers spotted a second distant star orbiting a well-known black hole and its stellar companion in a never-before-seen ...

In a paper published in Science Bulletin, a team of scientists presents drill core evidence indicating that a modern-like ...

This galaxy is now considered "dead" because its star formation seems to have stopped. The supermassive black hole at its core is thought to be directly responsible for this phenomenon. By pulling in ...

This work greatly improves the knowledge of how supermassive black holes, with a mass of more than a billion times that of the sun, are formed. These black holes detected within galaxies less than a ...

People argued over the enormous black holes spotted at those early times and the circumstances of their formation. Courtesy of Jakob Helton/University of Arizona; Image processing by: Ben Johnson/CfA, ...

This supermassive black hole is the beating heart of the Milky Way, driving the formation and evolution of our galaxy for its entire 13 billion-year-history, helping to give rise to solar systems ...

However, it can be quite challenging to figure out exactly when karst landscapes formed. In our new work published today in Science Advances, we show a new way to find the age of these enigmatic ...

Almost one-sixth of Earth's surface is covered by 'karst' landscapes, spectacular natural formations like caves and towers. These unique environments, formed by water sculpting bedrock over millennia, ...

Karst landscapes are formed when water dissolves rock, particularly limestone, over long periods. This erosion process leaves behind distinct features like towers and caves, offering a window into ...

In our study, we found a way to measure the age of pebble-sized iron nodules that formed at the same time as a karst landscape. This method has the technical name of (U/Th)-He geochronology.
