A rare and stunning phenomenon is surprising observers Heaven around the world: STEVE. This luminous spectacle, a unique blend of colors and lights, has been seen in several parts of the planet, creating stunning images and intriguing both scientists and enthusiasts of astronomy.
What is STEVE?
STEVE, which means Strong Thermal Emission Velocity Enhancement (in free translation, "Forte Thermal Emission Speed Increase"), is a rare natural phenomenon that resembles an aurora, but with some peculiar features.
Unlike traditional boreal or austral auroras, which mainly display green colors, STEVE features a purple or pink light strip, often accompanied by greenish bands in the form of "blins".
Scientists believe that the phenomenon is related to particles loaded into the Earth's magnetosphere, but the exact process behind the formation of STEVE is still being studied. Anyway, the result is an impressive visual spectacle.
Where and When STEVE can be viewed?
Like traditional auroras, STEVE is more visible in high-latitude regions, especially near the poles. It tends to appear during periods of intense geomagnetic activity, when solar particles interact with Earth's magnetic field.
Note Tip: If you are in an area with little light pollution and favorable weather conditions, keep your eyes on the sky during the nights of solar storms. With a little luck, you can witness this impressive phenomenon!
Why is STEVE Important?
STEVE not only offers a visual spectacle, but also awakens the interest of the scientific community. He challenges prior understanding of how particles in space interact with Earth's magnetic field. Researchers continue to study the phenomenon to better understand its origin and the conditions that provoke it.
