He discovered that the Moon was not a smooth, perfect sphere, as had been previously thought, but was covered in mountains and craters. He also discovered that Jupiter had four moons orbiting it, which challenged the prevailing belief that all celestial objects orbited Earth.

Galileo’s work was met with resistance from the Catholic Church, which at the time was the authority on all matters of science and religion. The Church believed that Galileo’s findings contradicted the Bible, and he was forced to recant his views. However, Galileo’s work eventually gained acceptance, and he is now considered to be one of the founders of modern science.

1668: Isaac Newton publishes his laws of motion and gravity, which provide a theoretical foundation for the scientific study of space.

Isaac Newton’s laws of motion and gravity are two of the most important laws in physics. They describe how objects interact with each other and how they move through space.

Newton’s first law of motion, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced external force. This law explains why planets continue to orbit the Sun and why objects fall to the ground when we drop them.

Newton’s second law of motion, also known as the law of acceleration, states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This law explains why heavier objects accelerate more slowly than lighter objects and why objects accelerate when we push them.

Newton’s third law of motion, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This law explains why rockets are able to launch into space and why we can walk on Earth.

Newton’s laws of motion and gravity have had a profound impact on the scientific study of space. They have allowed scientists to understand how planets and stars form and evolve, how spacecraft move through space, and how astronauts can live and work in space.

Some examples of how Newton’s laws of motion and gravity are used in space science include:

• Calculating the trajectories of spacecraft: Newton’s laws of motion are used to calculate the trajectories of spacecraft so that they can reach their destinations safely and efficiently.
• Understanding the formation and evolution of planets and stars: Newton’s laws of gravity are used to understand how planets and stars form and evolve. For example, Newton’s laws of gravity explain why planets orbit the Sun in elliptical orbits.
• Developing new technologies for space exploration: Newton’s laws of motion and gravity are used to develop new technologies for space exploration, such as rockets and space stations. For example, Newton’s laws of motion are used to design rockets that can propel spacecraft into space.

Newton’s laws of motion and gravity are essential for understanding and exploring the universe. They have had a profound impact on space science and continue to inspire new discoveries and innovations.

1846: Johann Gottfried Galle discovers Neptune, the eighth planet in the solar system.

Johann Gottfried Galle was a German astronomer who discovered Neptune, the eighth planet in the solar system, on September 23, 1846. Galle’s discovery was based on calculations made by the French astronomer Urbain Le Verrier, who predicted Neptune’s existence and position.

Le Verrier had noticed that the orbit of Uranus was not behaving as expected. He hypothesized that there must be another planet beyond Uranus that was causing the disturbance. Le Verrier made detailed calculations of the predicted planet’s position and sent them to Galle, asking him to search for it.

Galle and his assistant, Heinrich Louis d’Arrest, found Neptune on the same night that they received Le Verrier’s calculations. They were able to identify Neptune because it was located in the exact position that Le Verrier had predicted.

Galle’s discovery of Neptune was a major milestone in astronomy. It was the first time that a planet had been discovered based on mathematical calculations rather than direct observation. Galle’s discovery also confirmed the accuracy of Newtonian mechanics and showed that the laws of physics apply throughout the universe.

Hubble made his discovery by studying the light emitted from distant galaxies. He observed that the light from these galaxies was redshifted, which meant that the galaxies were moving away from us. Hubble also found that the more distant a galaxy was, the redshifted its light was. This observation led Hubble to conclude that the universe is expanding, and that the galaxies are moving away from each other at an accelerating rate.

Hubble’s discovery of the expanding universe was a major milestone in astronomy. It showed that the universe is not static, but is constantly changing and evolving. Hubble’s discovery also led to the development of the Big Bang theory, which is the prevailing theory of the origin and evolution of the universe.
