Welcome to a fascinating tour into the amazing world of modern astronomers! The study of the universe has never been more exciting or accessible than it is today, a time of ground-breaking discoveries and tremendous technology developments. Join us as we explore the creative minds, ground-breaking discoveries, and cosmic riddles that shape the field of modern astronomy. Our blog is your gateway to the cutting edge of human knowledge, whether you want to understand the mystery of black holes or see the birth of new stars. Let's talk about modern astronomers and their discoveries through this blog.🚀
Nicolaus Copernicus
He is a Polish astronomer known as the father of modern astronomy. Also, he has written a book called 'De revolutionibus orbium coelestium'. Copernicus calculated the relative distance between the planets. He proposed a heliocentric model and a solar system model with circular orbits.

Tycho Brahe
Tycho Brahe was a Danish astronomer well known for accurate astronomical observations. He is the author of 'De Nova Stella'. He built an observatory called 'Uraniborg' (Castle of the Heavens). In 1572, Tycho discovered a supernova in the constellation Casiopian.
Galileo Galilei
Galileo Galilei is known as the father of observational astronomy. He invented the thermoscope and used his telescope, which was well-improved for his observations. He observed the four largest satellites of Jupiter, Saturn's rings, the stars of the Milky Way, and the sunspots as well. He defended his views in the 'Dialogue between Two Great World Systems' and 'Siderus Nuncis' (The Starry Message) books. Also, his observations supported the heliocentric model, which was suggested by Copernicus.

Johannes Kepler
Johannes Kepler He was a German astronomer, well known for his three laws of planetary motion, which we called Kepler's laws of planetary motion.
👉First Law
A planet's orbit is an eclipse (not circles) with the sun at one of the two foci.
👉Second Law:
A line segment between a planet and the sun sweeps out equal portions at equal time intervals.
👉Third law
The square of a planet's orbital period is related to the cube of each semi-major axis length.

Sir Isaac Newton
Sir Isaac Newton, was an English polymer scientist active as a mathematician, physicist, and astronomer. As a philosopher, he propounded the three laws of motion, which are the basic principles of modern physics. It resulted in the formulation of the laws of universal gravitation. He is known as the discoverer of constant gravity. He is the key point of the scientific revolution. He constructed a reflecting telescope. Also, he has written naturalist Principia Mathematica, which is the fundamental work of modern science.
Newtonian laws of motion
👉First law
An object wants to change its motion unless a force acts on it.
👉Second law
The force on an object is equal to its mass times its acceleration.
👉Third law
When two objects interact, they apply forces to each other of equal magnitude and in opposite directions.

Christian Huygens
Christian Huygens was a Dutch mathematician, astronomer, and experimental scientist. He studied Saturn's rings and discovered Titan, which is the largest moon of Saturn. He also invented the pendulum clock and was the most accurate timekeeper in astronomical history for over 300 years.
William Herschel
William Herschel was a British astronomer and the founder of sidereal astronomy. He constructed many telescopes. He discovered infrared radiation and also found Uranus and its moons. (Titania and Oberon) He was the first President of the Royal Astronomical Society.
William Parsons
William Parsons was an Anglo-Irish astronomer, and he built giant telescopes. He discovered the spiral nature of some nebulae. (Spiral Galaxies) Whirlpool Galaxy and The Crab Nebula received those names based on his drawings.

Edwin Hubble
Edwin Hubble was an American astronomer. Extragalactic astronomy, observation, and cosmology were his main fields. Hubble is mostly well known for the Hubble Space Telescope, which was named in his honor. Hubble is famous for his law, which is known as Hubble's law today.
👉Hubble's Law
The recessional velocity of a galaxy increases with its distance from the Earth. Using the Hooker telescope at Mount Wilson Observatory, he discovered the andromeda nebula and also explained the expansion of the universe.
The voyage is far from ended in the dynamic field of contemporary astronomy. The cosmos still conceals numerous mysteries that have yet to be discovered, and the committed astronomers of today are on the verge of making discoveries that will fundamentally alter our perception of the world. We'll explore further into cutting-edge technology, cosmic occurrences and more knowledge on upcoming blogs. Prepare to be enthralled by the cosmological puzzles and the amazing brains solving them. Join us on this cosmic journey, and let's keep exploring the astronomy's endless wonders together. Stay tuned!✌💖
