How are red-blue lightning made? | Leader

WASHINGTON: We often see silver lightning flashing through the clouds in the sky. However, red and blue lightning flashes in some areas. About four years ago, in July 2017, red and blue lightning flashes were found in the skies over the Hawaiian Islands. His images were captured by the Gemini North Telescope at the Gemini Observatory in Mona Kia. Now, researchers have provided information on how these lightnings are generated.

The US National Optical-Infrared Astronomy Research Laboratory recently released the images as ‘Image of the Week’. The lab says that looking at these photographs, it looks as if some special effects are being used. These lightnings are called ‘Red Spites’ and ‘Blue Jets’. They are very difficult to capture in a normal camera. They shine in as little as a tenth of a second and are hard to see from the ground. This is because they mostly shine in the clouds during storms. They are captured on telescope cameras monitoring bad weather. This camera system captures images of the sky every thirty seconds. Electricity is usually generated between charged air, clouds and ground. The ‘Red Spites’ and ‘Blue Jets’ are formed in different places in the sky and they go in the direction of space. Red spots are lightning ‘ultrafast bursts’ that are 37 to 50 miles above the atmosphere. Some spites are jellyfish-shaped. Are like other threads. They are called ‘Carrot Spites’. Blue jets form near the Earth. They are cone-shaped electrical discharges and are even brighter than spits. They glisten on the clouds. Storm clouds can be up to fourteen miles above the earth. The Blue Jets continue to rise and disappear for up to thirty miles. They travel at 22,300 miles per hour.
