Discover what exist in the universe
Before 4.5 billion years ago, Earth had a rocky beginning. We had just collided with an early planet the size of Mars, a cataclysmic event that melted both planets and created our moon from a large lump of lava. This effect set the stage for the Hadean Eon, which got […]
The earth’s (nearly) perpetual solar orbit Since the dawn of time, people have wondered why the earth revolves around the sun. The solution lies in the strong gravitational pull that holds the Sun and planets in our Solar System together. The gravity of the Sun is what keeps the Earth […]
I. The forgotten Dwarf Planet-Ceres A. Meaning of Ceres Is Pluto the sole dwarf planet in the Solar System? Deep in the space hidden from our eyes is a planet whose surface temperature reaches a whopping maximum of 180 Kelvin and as low as 240 Kelvin. Named after the Roman […]
Eris, the unremembered planet When Michael Brown reported on February 28, 2004, the discovery of Sedna, an object believed to be almost 2,000 km in diameter and circling between the Kuiper belt and the inner section of the Oort Cloud. It appeared to everyone that the solar system had found […]
Triton is the largest moon in the Neptune system and one of the largest in the solar system. It was discovered on October 10, 1846, just 17 days after the discovery of the planet it orbits. Shall we attempt to investigate it further? 33 years ago, the Voyager 2 spacecraft […]
Why are Venus and Mercury moonless? Nine planets, more than 120 moons, millions of asteroids and other stony objects, and countless comets orbit our Sun. Collectively, they constitute our home in this vast cosmos, the Solar System. Mercury is the planet closest to the sun, followed by Venus, Earth, and […]
Why do we not investigate Venus since it is considerably closer to Earth than Mars? Which planet is closest to Earth? This is not Mars. Although Mars is a well-known planet, it does not hold the title of nearest planet. Venus is the planet that is closest to Earth in […]
Why is it so challenging to reach Pluto? Pluto is the most distant celestial body that a spacecraft has ever reached. This dwarf planet is more than 6 billion kilometers from Earth, and on July 14, 2015, only the New Horizons spacecraft was able to look at it directly. But […]
Is Jupiter an ineffective star? What would occur if it actually became one? Numerous astronomy papers, especially on the Internet, continue to assert that Jupiter should be considered a “failed star,” or a celestial entity whose mass “nearly” permitted it to ignite nuclear fusion reactions, but failed to do so. […]
Why is it so challenging to reach Uranus, the most peculiar planet? Uranus is the only planet whose axis is tilted. As a result, one of its poles is always pointing at the sun and the other in the opposite direction, making it one of the strangest planets and also […]
