Mars died 3.5 billion years ago — and we now know why. A magnetic field collapse exposed the planet to the Sun’s solar wind, stripping away the atmosphere and boiling off the ancient oceans. ESA missions like Mars Express and ExoMars still map the traces of this catastrophic past. A world that once looked Earth-like… became silent forever.

What happens if two super-strong magnets collide?

Detailed Explanation on Instagram: "The comparison between an MRI machine and the Earth’s magnetic field highlights a staggering difference in physical force, measured primarily in units called Teslas. While the Earth’s magnetic field is essential for navigation and protecting the atmosphere, it is remarkably weak, measuring roughly 0.00005 Tesla. In contrast, a standard clinical 3.0T MRI scanner operates at 3.0 Tesla, making it 60,000 times more powerful than the natural magnetism of our planet

FactevoX on Instagram: "The strong magnetic field inside an MRI machine is powerful enough to pull metal objects across a room.MRI stands for Magnetic Resonance Imaging, and it uses magnets up to 60,000 times stronger than Earth’s magnetic field to align hydrogen atoms in your body. . . When radio waves are applied, these atoms release signals that computers use to create detailed images of organs and tissues — without any surgery or X-rays. . That’s why hospitals take extreme precautions: even
