Moon and Sun Eclipse


Gerhana terdiri daripada dua, iaitu gerhana Bulan, dan gerhana Matahari. Kedua-dua ini berlaku apabila Bumi, Bulan dan Matahari betul-betul berada pada satu garisan yang lurus.  Yang membezakan antara dua jenis gerhana ini ialah, apakah yang berada di tengah-tengah? Apakah yang membentuk bayang-bayang gergasi? Apa pula yang terlindung?
Gerhana Bulan berlaku apabila Bulan – Bumi – Matahari, tersusun sebegitu pada garis lurus.Manakala, gerhana Matahari berlaku apabila Bumi – Bulan- Matahari, tersusun sebegitu pada garis lurus. Lihat rajah di atas.Apabila kejadian atau situasi di atas berlaku, cahaya Matahari akan dihalang oleh objek yang amat besar. Gerhana Bulan dihalang daripada menerima cahaya Matahari kerana bayang-bayang Bumi.Gerhana Matahari pula berlaku apabila sebahagian atau keseluruhan Matahari dilindung oleh objek yang besar iaitu Bulan.Sekiranya kita berada dalam situasi gerhana Matahari, kita tidak boleh melihat Matahari secara langsung. Ini kerana cahaya Matahari yang sangat tajam boleh merosakkan titik fokus dalam mata yang boleh menyebabkan buta.Jadi, gunakanlah alat bantu yang sesuai, seperti negatif filem hitam yang ditindih kira-kira 3 keping, atau melalui besen berisi air, atau cermin mata khas seperti gambar di atas (bukan cermin mata 3D yang diberi pinjam di pawagam! Itu tidak boleh!).
