Elves are transient luminous events that appear as expansive rings high above lightning strikes, observable only with advanced low-light cameras due to their fleeting nature. These phenomena are caused by strong electromagnetic pulses from both positive and negative discharges, and even intracloud discharges. Recent discoveries also link their formation to terrestrial gamma rays. Ongoing research delves into the complexities of the lightning current and other factors necessary to produce elves. Dive into this article to explore the dynamic and colorful interactions in the skies above.
Solar energy has evolved from its humble beginnings to become a cornerstone of the global energy system. Starting with the first practical silicon solar cell in 1954, the sector experienced a surge in innovation and investment, especially after the oil crisis of the 1970s. Today, solar modules have efficiencies of over 22% and their costs have halved since 2022. The International Renewable Energy Agency reports that solar energy is the fastest growing renewable energy source and that global capacity will reach 1,419 GW by the end of 2023. Advances in perovskite and quantum dot solar cells as well as bifacial and floating power plants promise even higher efficiencies and innovative applications. Read the article to find out more about the exciting advances and future potential of solar energy.
Terrestrial gamma-ray flashes (TGF), often referred to as dark lightning, are a captivating atmospheric phenomenon linked to thunderstorms and lightning. Discovered accidentally by NASA's Gerald Fishman in 1994, TGFs are brief, high-energy gamma-ray bursts lasting only microseconds. Distinguished from typical lightning by their cold plasma composition and rapid occurrence, TGFs have challenged our understanding of lightning mechanisms. In this article, we delve into the intriguing world of TGFs, exploring their discovery, characteristics, and the ongoing research that continues to unveil their mysteries.
Sprites, also known as red lightning, are mysterious electrical discharges that light up the mesosphere above thunderclouds, triggered by positive lightning. First described by Nobel laureate C.T.R. Wilson in 1925 and captured on camera in 1989, these stunning phenomena resemble clusters of red or orange lights and differ significantly from typical lightning. In this article, we talk about the fascinating behavior of stripes, their origin and characteristics.
