Geomagnetic superstorm shrunk Earth’s protective plasmasphere
  • The geomagnetic superstorm Gannon in 2024 caused a reduction in the size of Earth's plasmasphere, which is essential for blocking harmful radiation. This phenomenon was accompanied by the generation of auroras.
  • The shrinking of the plasmasphere due to such superstorms raises concerns about the potential increase in radiation exposure on Earth, emphasizing the need for monitoring solar activity and its impacts on our planet's protective layers.

New research indicates that Theia, the celestial body theorized to have collided with Earth to form the moon, originated from a region closer to the sun. This finding challenges previous assumptions about Theia's location and provides new insights into the dynamics of the early solar system.
Earth and Theia smashed to birth the moon, but did they first start out as close neighbors?
NeutralScience
The prevailing theory suggests that the building blocks of Earth and Theia primarily originated in the inner solar system. This indicates that Earth and Theia may have been neighboring celestial bodies before their collision, which ultimately led to the formation of the Moon.
