FAQs
-
How does the Sun produce energy? The Sun produces energy through a process called nuclear fusion in its core. During this process, hydrogen nuclei fuse to form helium, releasing an enormous amount of energy in the form of light and heat. This fusion process is what powers the Sun and provides the energy that sustains life on Earth.
-
What causes solar flares and how do they affect Earth? Solar flares are sudden, intense bursts of radiation caused by the release of magnetic energy stored in the Sun’s atmosphere. They can affect Earth by disrupting satellite communications, navigation systems, and power grids. Solar flares are also responsible for the beautiful auroras seen near the polar regions.
-
What are the challenges in studying the solar corona? Studying the solar corona is challenging due to its extremely high temperatures and low density, which make direct observation difficult. Another challenge is the Sun's brightness, which can overpower instruments trying to observe the faint corona. Recent advances in technology and missions like the Parker Solar Probe are helping to overcome these challenges.
-
How has solar observation evolved over the years? Solar observation has evolved significantly from early ground-based telescopes to advanced space-based observatories. Innovations in technology have allowed for detailed study of the Sun's surface, its atmosphere, and solar phenomena like flares and coronal mass ejections. Modern observatories can observe the Sun in various wavelengths, providing comprehensive data about its activities.
