Did you know astronomy facts?

The sun and moon may look fairly similar in size when you look at the sky, but don’t let your eyes fool you. Not only does the sun actually dwarf the moon in size—it’s 400 times larger—it’s also 400 times further away from Earth than the moon. That distance gives the sun the illusion of appearing moon-size.

Is there a planet made of diamonds?

In 2012, Yale University scientists published a study announcing the identification of a planet rich in diamonds. Called 55 Cancri e, the planet is “possibly covered in diamond, rather than water and granite,” scientists explained at the time. The exoplanet is twice the size of Earth but has eight times its mass.

What is interesting about being an astronomer?

Astronomers study objects found in space such as planets, moons, stars, solar systems and galaxies. Astronomy is one of the oldest fields of science. Becoming an astronomer usually requires a high level of education such as a PhD in physics. Strong math skills are important for astronomers.

Who was the first astronomer?

The first documented records of systematic astronomical observations date back to the Assyro-Babylonians around 1000 BCE. From this cradle of civilisation in Mesopotamia – in the southern part of present-day Iraq – astronomers had built up knowledge of the celestial bodies and recorded their periodic motions.

What is fascinating about astronomy?

Astronomy is a fascinating, complex and deeply rewarding subject. Celestial objects have been studied by humankind for millennia and are the inspiration of countless books, movies and TV shows. An ever-developing topic of study, astronomy is rich with exploration opportunities and unanswered questions.

How many astronomers are there in the world?

The worldwide com- munity of professional astronomers is only about 10,000; most are located in the US (with about 1,000 in the UK and 250 in Australia). Under the heading of “astronomy” there are many fields (and sub-fields) of research.

Who found space?

The first human in space was the Soviet cosmonaut Yuri Gagarin, who made one orbit around Earth on April 12, 1961, on a flight that lasted 108 minutes.

Who is the most famous astronomer?

Galileo Galilei

The astronomer (also mathematician, physicist and philosopher) turned the new observational tool toward the heavens, where he discovered the four primary moons of Jupiter (now known as the Galilean moons), as well as the rings of Saturn (opens in new tab).

Who discovered stars?

Galileo Galilei, an Italian scientist, lived from 1564 to 1642. In 1610, he was the first person we know of to use the newly invented telescope to look at the stars and planets.

How are stars born?

A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.

Which star is hottest?

White stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped. They are round like our sun.

Why is Sun called a star?

Stars are space objects that produces their own energy through fusion reaction of gasses. They are like round, gas burning, energy producing luminous orbs. Sun- the star of our solar system is a star because it produces energy by the fusion reaction of Helium turning into Hydrogen.

Will the sun ever burn out?

But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the formation of our solar system, about 4.5 billion years ago.

How old is the sun?

4.603 billion years
Sun / Age

Does the sun move?

Its spin has a tilt of 7.25 degrees with respect to the plane of the planets’ orbits. Since the Sun is not solid, different parts rotate at different rates. At the equator, the Sun spins around once about every 25 Earth days, but at its poles, the Sun rotates once on its axis every 36 Earth days.

Is the Sun made of fire?

The Sun isn’t “made of fire”. It’s made mostly of hydrogen and helium. Its heat and light come from nuclear fusion, a very different process that doesn’t require oxygen. Ordinary fire is a chemical reaction; fusion merges hydrogen nuclei into helium, and produces much more energy.

Is our sun a star?

Our Sun is an ordinary star, just one among hundreds of billions of stars in the Milky Way Galaxy. As the only star we can observe in detail, it provides a basis for our understanding of all stars. The Sun is composed almost entirely of hydrogen and helium gas.
