NASA Explains Phenomenon Behind Spectacular Auroras Illuminating Earth’s Skies

NASA Explains Phenomenon Behind Spectacular Auroras Illuminating Earth’s Skies

Breaking News, Climate Actions, Environment, Space
Auroras, the mesmerizing celestial light shows, have once again graced the skies across several regions, captivating spectators with their vibrant hues of pink, green, and purple. This dazzling display, commonly known as the "northern lights," is a result of a powerful solar storm that has swept across the planet. The phenomenon, triggered by eruptions on the Sun, has been elucidated by the National Aeronautics and Space Administration (NASA) in a recent thread on X (formerly Twitter), shedding light on the intricate interplay between solar activity and Earth's atmosphere. According to NASA, solar eruptions manifest in two primary forms: solar flares and coronal mass ejections (CMEs). Solar flares, intense bursts of light, occur when the Sun's magnetic fields undergo abrupt rearrange...

NASA-ISRO Collaboration: NISAR Satellite to Provide Unprecedented Insights into Earth’s Cryosphere

Breaking News, Disasters, Space, Thoughts & Talks
NASA and the Indian Space Research Organisation (ISRO) are joining forces to launch the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, slated to become a game-changer in monitoring Earth's cryosphere – the frozen surfaces of land and ice. Set to launch in 2024 from southern India, NISAR will offer unparalleled observations, measuring key Earth vital signs related to the health of wetlands, ground deformation caused by volcanoes, and the dynamics of land and sea ice. NISAR's unique capabilities lie in its ability to observe nearly all of the planet's land and ice surfaces twice every 12 days. This comprehensive coverage will be facilitated by two radar systems: an L-band system with a 10-inch wavelength and an S-band system with a 4-inch wavelength. The L-band is adept at penetrat...
