What are the factors that led to Venus becoming an scorching planet?
Venus, commonly known as “Hell,” stands as the Solar System’s hottest planet, boasting surface temperatures soaring close to 500 degrees Celsius and surface pressure 92 times higher than Earth’s at sea level.

Theorists propose that in the past, Venus may have resembled Earth’s current state, hosting an atmosphere that could have supported life. Such observations prompt intriguing inquiries about the origins of life on Earth, given the similarities in their formation and composition.
The reason behind Venus’ evolution into its current fiery state remains a puzzle. Two main theories suggest that either the Sun’s intense heat “baked” Venus or volcanic activity contributed to its transformation.
The true origin of the Moon
The true origin of the Moon has been a subject of scientific investigation and debate. Initially, it was thought to form through the coalescing of debris from the formation of the Sun, similar to other planets. However, the story took a different turn when Apollo mission astronauts brought back surface samples from the Moon for analysis.

Geologists discovered that the Moon is covered in a unique type of rock called anorthosite. These sparkling, light-colored rocks possess high reflectivity, causing the Moon to shine brightly in the night sky.
It is believed that this type of rock can only be formed from magma (molten rock), implying that the Moon might have experienced intense heat, nearly melting it.
Scientists are still uncertain, but the proposed hypotheses paint a vivid picture of a fiery past for the Moon.
Is there any life in human waste on the Moon?

Astronauts on Apollo missions had to dispose of waste, including human waste, on the Moon to reduce the weight for the return journey. Throughout the Apollo missions, astronauts left behind 96 bags of human waste on the lunar surface, raising intriguing questions about astrobiological implications.
Are there other аdvаnсed сіvіlіzatіons on Eаrth?
While other scientists continue their quest to find advanced civilizations in the far reaches of the universe, climate scientist Gavin Schmidt and astrophysicist Adam Frank propose an alternative question: Could there have been other advanced civilizations in Earth’s history, buried deep within its crust?
This inquiry goes beyond the confines of the Solar System and may offer insights into other inquiries during space exploration. Is it possible for an intelligent form of life on any planet to leave traces of its existence behind?
Can we alter the trajectory of an asteroid to prevent it from colliding with Earth?
Natural calamities such as volcanic eruptions, earthquakes, hurricanes, and floods are inherent parts of life on Earth. However, there is one potential catastrophe that we might have the ability to prevent: an asteroid impact.

The challenge lies in our lack of experience in intentionally altering the course of asteroids, leaving us uncertain about its feasibility.
Recently, NASA carried out the Double Asteroid Redirection Test (DART) mission. They launched a spacecraft the size of a car to collide with the asteroid Dimorphos, which measures 60 meters in diameter, at a speed of 24,000 km/h, aiming to answer the question: Can we divert an asteroid’s trajectory?
Was there life on Mars?
Although present-day Mars may appear as a barren desert without any signs of life, scientists have uncovered substantial evidence suggesting that Mars might have once resembled Earth.
“4 billion years ago, Mars was very different from what it is today, but you can still observe remnants of its past,” says astrophysicist Lindsay Hays. “There are traces of a large river delta, indicating not only the presence of water but also a significant amount of water that flowed for an extended period, creating deposits.”
Where there is water, there is the potential for life. In 2021, a successful rover was launched to Mars, providing us with the best opportunity to address the question, “Was there ever life on Mars?” If the answer is affirmative, it could profoundly impact our understanding of the existence of life in the universe.
Is there a ninth planet in the Solar System?
In 2006, the International Astronomical Union revised the definition of a planet, resulting in Pluto’s demotion as a planet in the Solar System. Since then, the official count of planets in the Solar System stands at 8.
However, various hints have suggested the potential existence of a massive planet lurking beyond Neptune, awaiting discovery. Astronomers continue their search for this planet, raising questions about its existence and the gravitational influence it exerts on other celestial bodies.
Will these clues eventually lead us to the discovery of a true ninth planet? It remains a possibility, but the search is undoubtedly a challenging task.
