ESA's Solar Orbiter, a collaborative mission with NASA, is poised for its closest-ever approach to Venus, marking a pivotal moment in its mission to study the Sun's polar regions. The spacecraft's maneuver will alter its orbital trajectory, granting scientists a rare opportunity to observe the Sun's poles, a perspective unattainable from Earth. Insights gained from this unique vantage poin

Black holes are not just cosmic voids; they are dynamic engines capable of generating and redistributing immense amounts of energy. Encircled by swirling disks of gas and dust-known as accretion disks-these enigmatic entities can channel energy through powerful jets when strongly magnetized, a process primarily governed by the Blandford-Znajek (BZ) effect. Despite its prominence in theoret
