Scientists have solved the 200-year-old mystery of the location of a massive volcanic eruption that spewed such a large volume of gases that it blocked sunlight, making the sun appear blue.

Scientists have identified the “mystery volcano” that erupted in 1831 and cooled Earth’s climate. They have linked it to an island volcano in the northwest Pacific Ocean.

In the summer of 1831, an enormous volcanic eruption spewed sulfur gas into Earth’s atmosphere. The particles scattered sunlight, making our star appear green, purple and blue. Its rays struggled to reach the planet’s surface,

Scientists Make Groundbreaking Discovery About a Volcanic Eruption That Almost Turned the Sun Blue Scientists solved the 200-year-old mystery of the location of a large volcanic eruption that exerted a massive volume of gases which blocked sunlight and made the sun look blue.

In the summer of 1831, people across the Northern Hemisphere experienced bizarre and unsettling phenomena: the sun appeared blue, purple, and even green, and temperatures dropped dramatically during what should have been the warmest months of the year.

In 1831, the Earth shuddered. A massive volcano erupted with such ferocity that it dimmed the skies and cooled the planet. Crops failed, famine spread, and the Northern Hemisphere entered a climate-altered reality.
