Question

Hey !

I was poking around your site, reading all your great content, and I saw you had a resources page here: https://www.school-for-champions.com/astronomy/resources.htm

Believe it or not, I actually have a article on this exact subject which I think may be beneficial to your readers

as it provides lots of useful information and tips. Check it out: A Guide on Stargazing Looking Through Binoculars

I don't understand Astronomy at all

February 14, 2017

Question

I don't understand Astronomy at all. I don't enjoy studying about a whole new world that I've never visited. Is their an easy way to understand Triangulation, Radio telescopes?

Jawerriya - Canada (27880)

Answer

It can be interesting to look into the night sky and see all the numerous stars in the sky, as well as their movement throughout the year. Some people like to learn the constellations and arrangement of the stars.

However, Astronomy can delve deeper to find out what the planets and stars are made of. It is a scientific study that some people are interested in and others are not.

Triangulation is a method to determine distance using trigonometry. In Astronomy, it is useful to approximate distance of far-off objects.

A radio telescope uses radio waves instead of light ways to detect distant objects in space. In some situations, it works better than visible light.

Although teachers can often learning many facts without making the subject interesting, it is good to find things about the subject you like.

Best wishes for success in your studies.

Moon

Correcting number of Jupiter's moons

January 24, 2017

Question

On your article about the Earth's Moon, you said the Earth has one Moon and Jupiter has 9 moons. This is incorrect, NASA has recently discovered that Jupiter has 67 moons! I believe the number is up to 67 now. Up until a few years ago, they knew it had at least 63 moons. Galileo discovered 4 of them in the early 1600s. I can only see 5 of them with my modern day, powerful telescope.

David - USA (27823)

Answer

Thanks for the information. I corrected the Characteristics of our Moon page as well as added material on Jupiter and Jupiter's 67 Moons.

Black Holes

Can a graviton escape from a black hole?

May 19, 2016

Question

Does graviton escape from the black holes? If no then why other celestial objects feels their gravity, if yes then how can graviton escape from the place from where even light cant escape?

Vinamra - India (27017)

Answer

A graviton is a hypothetical particle that is responsible for gravitational forces, as part of the quantum theory of gravitation. Since it is supposed to be the source of gravitational forces through an exchange between masses, it really would not be moving freely like in escaping from a Black Hole.

Other celestial object do feel the gravitational forces from a Black Hole, as witnessed by objects being drawn into the hole. But its forces are reduced as the square of the distance from the Black Hole.

Galaxy versus Galactic motion

May 1, 2016

Question

What is the difference between Galaxy and Galactic motion?

- USA (26973)

Answer

A galaxy is a system of stars and other materials that are bound together by gravitational forces. The Milky Way is an example of a galaxy.

Galaxies tend to rotate very slowly about some center area. They also move in space as compared to other galaxies.

Question

Comments:

THE SUN MOVES ROUND THE EARTH

What is the Earth’s gravitational force?

Scientists Newton formula is Wrong

The sun is flat!

Moon is not Earth’s satellite

SUN IS NOT A PLANET

NOTE: The arguments have been deleted because they are too extensive to be published.

ROBIUL ISLAM - Bangladesh (26644)

Answer

No, the Sun does not move around the Earth. that has been proven many times.

The Earth’s gravitational force is approximately 9.8 m/s^2 times the mass of the object.

Newton's Third Law is correct. A force requires an opposite force.

The Sun is not flat. Your sources are inaccurate.

The Moon is Earth’s satellite. This is by definition.

It is true that our Sun is not a planet. It is a sun.

The starts do not move around the Sun. Your sources of information are incorrect.
