An artist's depiction of a solar storm impacting Mars and removing ions from the planet's upper atmosphere. Could Earth face a similar fate billions of years from now when our planet's magnetic field weakens or disappears?
~2-3 Billion: The Solidification of Earth’s Core – Future Implications

As Earth's core cools and solidifies over the next few billion years, the cessation of its magnetic field will lead to significant atmospheric and geological changes, fundamentally altering the planet's environment

High-resolution image of a single-celled bacterium called Magnetospirillum magnetotacticum, or MS-1, containing a linear chain of magnetosomes composed of the mineral magnetite. The cell measures approximately 0.00008 inch (2 microns) in length.
1975: Unveiling the Mystery of Magnetoreception – Nature’s Unique Navigation System

Magnetoreception, a unique navigational sense observed in various species, allows alignment with Earth's magnetic field. Discovered by Salvatore Bellini and further studied by Richard Blakemore, this sense remains a captivating mystery in animal behavior and [...]

The aurora borealis, or northern lights, gleaming brightly over Bear Lake, Alaska, in January 2005. Auroral displays like this are the result of high-energy solar-wind particles interacting with Earth's magnetic field and with particles trapped in the Van Allen radiation belts.
1958: Discovery of Earth’s Van Allen Radiation Belts by Explorer 1

Explorer 1, led by James Van Allen, revealed the existence of Earth's Van Allen Radiation Belts, a major discovery in space science and Earth's magnetic field study

c. 4.54 Billion BCE: The Formation of Earth’s Core – A Journey Through Early Solar System Chaos

Explores the early history of the solar system and the formation of Earth's core. It discusses the process of accretion and differentiation that led to the creation of Earth's core, mantle, and crust structure, and [...]
