Earth, or Prithvi (पृथ्वी) in Nepali, is our home, the only known planet to support life. It has a diverse environment with oceans, continents, and a protective atmosphere. Earth's atmosphere is composed mainly of nitrogen and oxygen, which is essential for life. The planet has a dynamic climate, with seasons and weather patterns that vary across different regions. Earth's unique features, such as liquid water and a stable temperature, make it habitable for a wide range of organisms. The planet also has a magnetic field that protects it from harmful solar radiation. Studying Earth helps us understand the conditions necessary for life and the importance of preserving our environment. Numerous satellites and missions monitor Earth's climate, geology, and biodiversity, providing valuable data for scientific research and environmental conservation.

Mars (मंगल - Mangal)

Mars, or Mangal (मंगल) in Nepali, is the fourth planet from the Sun and is often called the Red Planet because of its reddish appearance. It’s a cold, desert-like world with a thin atmosphere. Scientists believe that Mars once had liquid water on its surface and could have supported microbial life. Mars has polar ice caps, canyons, and volcanoes, including Olympus Mons, the largest volcano and highest known mountain in the solar system. The planet has two small moons, Phobos and Deimos. Studying Mars helps us understand the potential for past or present life beyond Earth and the possibility of future human colonization. Missions like the Mars rovers (Curiosity, Perseverance) and orbiters (Mars Reconnaissance Orbiter, MAVEN) continue to explore its geology, climate, and potential habitability.

Jupiter (बृहस्पति - Brihaspati)

Jupiter, or Brihaspati (बृहस्पति) in Nepali, is the largest planet in our solar system, a gas giant composed mainly of hydrogen and helium. It has a strong magnetic field and a swirling atmosphere with distinctive cloud bands and the Great Red Spot, a massive storm that has been raging for centuries. Jupiter has dozens of moons, including the four largest, known as the Galilean moons: Io, Europa, Ganymede, and Callisto. These moons are diverse and fascinating, with features ranging from volcanic activity on Io to a possible subsurface ocean on Europa. Studying Jupiter helps us understand the formation and evolution of gas giants and the dynamics of planetary systems. The Juno mission is currently orbiting Jupiter, providing detailed data about its atmosphere, magnetic field, and internal structure.
