I was lucky enough to catch Awesome glimpse of the northern lights From my home this month when the largest solar storm to reach Earth in two decades produced the aurora borealis Latitudes are much further south ususally.

Despite living on the light-filled streets of central London, my smartphone camera captured a green haze and a pulsating layer of purple and pink light. Capturing this moment was an unforgettable experience that I thought would require expensive travel to the far north of our planet.

The storms that create stunning auroraes like the one you saw originate from the Sun’s dynamic magnetic field, an astrophysical mystery that scientists this week moved closer to solving.

NASA’s Solar Dynamics Observatory scientists used computer models to generate a four-day time frame of the Sun’s changing magnetic field. Field lines are more concentrated in magnetically denser regions.

Knowing how the Sun’s magnetic field works will help scientists improve predictions of space weather, which fascinates night sky watchers but can disrupt GPS and communications satellites.

The Sun’s toroidal magnetic field lines, which form a tangled network of structures more complex than those on Earth, are difficult to study. To understand what is happening, scientists create mathematical models.

A new model, which took more than a decade to develop and required a NASA supercomputer to perform detailed calculations, has found that the Sun’s magnetic field is generated closer to the surface than previously thought.

The team believes its model is more accurate because… It represents a unique solar feature.

A single gold earring found in the ruins of a 2,000-year-old building in the Pyrenees is a clue to how a devastating fire started. The inferno consumed the wooden structure, located in an Iron Age settlement called Tossal di Baltarga, and killed six animals that were confined to a stable.

Archaeologists believe that the fire was intentional. If it had been accidental, the building’s owners would likely have released the livestock and returned after the fire had died down to retrieve their hidden gold, which was hidden in a jar.

The arsonists may have been an invading army under the command of Hannibal, the Carthaginian general who led forces against the Roman Republic, according to the new study.

The fate of the people who used the building is unknown, however Excavations revealed telling details about life Of an Iberian people called Ceretani.

The moon appears above the megalithic rocks that make up Stonehenge, located on Salisbury Plain in Wiltshire, England.

The builders of Stonehenge placed the massive stones that make up the prehistoric monument in line with the sunrise and sunset on the longest and shortest days of the year, revealing an intimate understanding of the sun that is still visible today.

But is the 4,500-year-old site in southwest England – and potentially other megalithic monuments around the world – also aligned with the moon?

The idea that Stonehenge has a lunar link first gained popularity in the 1960s. However, this concept has not been systematically explored, yet.

Astronomers have observed the edge of a black hole – an area known as the “sinking zone” – for the first time.

Andrew Mummery, lead author of a new study on black holes One research colleague at the University of Oxford compared it to the “edge of a waterfall” at the end of a river, where material orbiting nearby stars falls into the abyss.

In the sunken region, matter can no longer remain in orbit, and instead rushes toward the black hole. But unlike a black hole’s event horizon or surface, light can still escape at this point.

Results, This is what Albert Einstein predictedIt could help astronomers better understand the formation and evolution of black holes.

The Eurasian jay may be capable of human-like memory, according to new research.

Corvids—the group of birds that includes crows, crows, and jays—are known for their intelligence. A species of corvid may be able to do something researchers refer to as “mental time travel.”

This type of remembering enables the mind to remember a piece of seemingly unimportant information that you have not consciously committed to memory – for example, remembering what you had for lunch yesterday.

Researchers working with Eurasian jays trained to find food hidden under cups said these birds may be able to perform a memory function.

In the experiment, which included decorated cups, it was jays The ability to remember the shape of a specific cupEven after rearranging the cups and the time delay.
