Jupiter is the largest planet in our solar system, with a mass approximately 2.5 times that of all other planets combined. It has a diameter of about 139,820 km and is a gas giant composed primarily of hydrogen and helium. The Sun is a star, not a planet, while Neptune and Earth are smaller than Jupiter.

The first manned mission to land on the moon was Apollo 11, which landed on July 20, 1969. Neil Armstrong and Buzz Aldrin became the first humans to walk on the lunar surface, while Michael Collins remained in orbit in the Command Module. This was a milestone achievement of the Space Race between the USA and USSR.

The Hubble Space Telescope has made numerous discoveries including finding some of the most distant galaxies ever observed. Hubble's deep field observations have allowed astronomers to look back in time to when the universe was very young. The telescope was launched in 1990 and continues to be one of the most important scientific instruments ever built.

NASA stands for National Aeronautics and Space Administration. It is the United States government agency responsible for the civilian space program as well as aeronautics and space research. NASA was established in 1958 and has been responsible for major achievements including the Apollo moon missions, Space Shuttle program, Mars rovers, and the International Space Station.

A meteor is the streak of light we see when a small meteoroid burns up in Earth's atmosphere. This phenomenon is commonly called a 'shooting star,' though it's not actually a star at all - it's a space rock creating a bright flash as it enters our atmosphere.

The International Space Station began construction in 1998 when Russia launched the first module, Zarya, on November 20. The station has been continuously inhabited since November 2000, making it one of humanity's greatest achievements in space cooperation.

Buzz Aldrin was the second person to walk on the moon, joining Neil Armstrong during the Apollo 11 mission in 1969. He got his nickname from his sister mispronouncing 'brother' as 'buzzer,' which was later shortened to Buzz.

A black hole is a region in space with gravity so strong that nothing can escape from it, not even light. They form when massive stars collapse at the end of their lives, creating a point of infinite density called a singularity.

Yuri Gagarin became the first human in space on April 12, 1961, aboard the Soviet spacecraft Vostok 1. His historic flight lasted 108 minutes and completed one full orbit around Earth.

The Aravalli Range is India's oldest mountain range, dating back about 2.5 billion years to the Proterozoic Eon. It extends across Rajasthan and represents one of the most ancient folded mountain systems globally.
