🌞The Sun emits ultraviolet (UV) light, which can be harmful to our eyes and skin.
🔭Telescopes equipped with special filters can allow us to safely observe the Sun and its phenomena.
🌅Sunspots, filaments, and prominences are some of the fascinating features visible on the Sun's surface.
👀Pinhole cameras can be used to project an image of the Sun onto a surface, enabling safe observation.
🌍The Sun provides vital energy for life on Earth, making it one of the most important astronomical objects.
Why is it harmful to look directly at the Sun?
—Directly looking at the Sun can damage our eyes due to the intense ultraviolet light emitted.
How can we observe the Sun safely?
—Special filters on telescopes, pinhole cameras, and projection methods can allow us to safely observe the Sun.
What are sunspots and why are they significant?
—Sunspots are dark spots on the Sun's surface caused by intense magnetic activity. They provide insights into solar dynamics.
What are filaments and prominences on the Sun?
—Filaments are cloudy structures made of gas, while prominences are bright clouds that extend beyond the Sun's surface.
Why is the Sun important for life on Earth?
—The Sun is the primary source of energy, providing light and heat necessary for photosynthesis and maintaining livable conditions on Earth.
