A spectacular solar phenomenon recently captivated astronomers. An immense column of plasma, nicknamed "The Beast," was observed above the Sun, projecting fireballs at incredible speeds.

This solar structure, whose size exceeds thirteen times that of Earth, was the first in a series of remarkable appearances. Photographers worldwide were able to immortalize this event, offering images of rare beauty.

Observations revealed this solar prominence extended over 165,000 kilometers (over 100,000 miles). Its changing appearance reminded some observers of a moving four-legged creature, hence its nickname.

These structures, composed of ionized plasma, are held together by invisible magnetic fields anchored to the solar surface. Though they can reach colossal sizes, they generally remain harmless to Earth.

Recent solar activity, including the appearance of two other major prominences, reflects the current active phase of the solar cycle. These events, while impressive, pose no direct danger to our planet.

What is a solar prominence?


A solar prominence is a luminous structure extending from the Sun's surface. It consists of plasma, an ionized gas, and is held in place by powerful magnetic fields.

These phenomena can persist for hours or even days before dissipating or transforming into solar flares. Their size varies considerably, with some reaching dimensions far exceeding Earth's.

Prominences are often associated with coronal mass ejections, though not all lead to such events. Their study helps better understand the Sun's magnetic dynamics.

Observing these structures also provides valuable clues about solar activity and its potential impact on Earth's space environment.
