About Auroras:

  • Luminous phenomena near Earth’s poles caused by charged particles interacting with the magnetic field and atmosphere.
  • Composition: Consist of gases like oxygen and nitrogen, along with particles.
  • Energy Release: Collisions of particles with the atmosphere release energy in the form of light.
  • Colour Variation: Colours in auroras depend on gas type and collision altitude.
About Aditya-L1:

  • Mission : Aditya-L1 is India’s inaugural space-based solar mission launched on September 2, 2023, by ISRO.
  • Orbit: Positioned in a halo orbit around the Sun-Earth Lagrange point 1 (L1) for an unobstructed view of the Sun.
  • Overcomes limitations of Low Earth Orbits, providing continuous solar observation crucial for scientific research and applications.

Geomagnetic Storm:

  • Definition: A disturbance in Earth’s magnetic field caused by solar emissions is known as a geomagnetic storm.
  • Cause: Triggered by solar coronal mass ejections (CMEs), which collide with Earth’s magnetosphere, disrupting its protective magnetic fields.
  • Disruptions: Geomagnetic storms can interfere with navigation systems and induce harmful currents in power grids and pipelines.
