Campfires of Sun
Why is it in news?
- A solar Orbiter built by the European Space Agency and NASA has delivered the closest photos ever taken of the sun's surface.
Campfires:
- These are tiny solar flares observed on the Sun’s surface.
- These tiny explosions are also called nanoflares.
- It could explain why the sun's outer shield, the corona, is 300 times hotter than the star's surface.
- Solar Orbiter ( (SolO):
(1) It is a Sun-observing satellite, developed by the European Space Agency (ESA) and NASA.
(2) Its primary mission is to examine the sun's polar regions.
(3) It will help researchers to understand the origins of the solar wind, charged particles that blast through our solar system and affect satellites and electronics on Earth.
