Space By Alphabet

These are words relating to our new BNC topic, Space, in alphabetical order - A-Z. I'll give a short (-ish) explanation for each word, showing my reasoning. I will also leave some links at the end of an explanation. I've tried not to include names of planets, as they are quite obvious, except Earth and Jupiter, purely because I find it quite interesting - Jupiter has at least 63 moons!

A is for Astronomy...

Astronomy is the study of objects in the sky; e.g. stars, planets, asteroids (another A), moons, galaxies, etc.

B is for Bode's Law...

A mathematical formula designed by Bode to generate the orbits of objects orbiting the Sun in A.U (astronomical unit). Although it appears to be accurate for the planets (including the asteroid belt) up to Uranus (interestingly, it actually predicted Uranus' orbit before it was discovered), it seems to go wrong after that and misses out Neptune. The law appears to back-up theories about how Solar Systems are formed (the distances between planets roughly doubles the further you move out of the Solar System) and it is more coincidental that the positions of objects up to Uranus fit in with Bode's Law. See more here: https://www.britannica.com/science/Bodes-law

C is for Comet...

A small ball of dust and gas that orbits the Sun, often in oval orbits. They are only visible when they are close enough to the Sun to start burning off their dust/gas. Some comets take a few decades (a decade is a period of 10 years) to complete an orbit, others take thousands of years. Some comets are also known to orbit Jupiter.

D is for Dark Matter...

Most of space is "dark matter"! It is matter (particles of gas and dust) that is too dim to be picked up by telescopes, but astronomers know it's there by the influence of its gravity (recognised by the effect it has on other objects).

E is for Earth...

We live on Earth! It's the third planet from the Sun and the fifth largest planet in the Solar System. The only planet in the Solar System where large quantities of water exist, and the only planet in the Universe on which life is known to exist. Earth has one natural satellite (the Moon). See more here: https://en.wikipedia.org/wiki/Earth

F is for Flat Earth Society...

The Society originally based in England but now in California which believes that Earth is flat, despite overwhelming scientific evidence proving otherwise. As you may find, I strongly believe the Earth is SPHERICAL. Their official website: https://www.tfes.org/

G is for Galaxies...

A large group of stars, bound together by gravity. Quite often, the galaxy will form a spiral or circular shape.

H is for Hydrogen...

Hydrogen is the most common element in the universe and also the simplest. Stars in their early life are made up almost entirely of hydrogen. By converting this hydrogen into helium (another H!), through a process called binary fission, they produce heat and light.

I is for Infrared...

This was quite a hard one! Invisible rays. They cannot be seen as the waves that produce them are longer than the waves at the red end of a rainbow. They can be felt though, usually as heat.

J is for Jupiter...

Fifth planet from the Sun and the largest planet in the Solar System. A Gas Giant made up mostly of hydrogen and helium, and to put into consideration how big Jupiter really is, it is large enough to contain all of the other planets in the Solar System. The Red Spot on Jupiter is an Earth-sized storm that has been raging for hundreds of years. There are at least 63 moons orbiting Jupiter. See more here: https://en.wikipedia.org/wiki/Jupiter

K is for Kari...

A moon of Saturn, discovered in 2006 by Scott Sheppard, David Jewitt, Jan Kleyna and Brian Marsden. It orbits Saturn in a retrograde direction, opposite to the direction that Saturn spins. It is about 22,305,100 kilometres (13,859,747 miles) from Saturn and takes over 1,243 days to get around the planet. It has a diameter of about 7 kilometres (4.3 miles). Source: https://en.wikipedia.org/wiki/Kari_(moon)

L is for Lunar...

You might've heard of a lunar eclipse (where the moon appears darkened as it passes into the Earth's shadow), but the word "Lunar" simply means resembling the Moon.

M is for Meteor...

According to The Telegraph, "A meteor is a meteoroid – or a particle broken off an asteroid or comet orbiting the Sun – that burns up as it enters the Earth's atmosphere, creating the effect of a "shooting star". Meteoroids that reach the Earth's surface without disintegrating are called meteorites." See here: https://www.telegraph.co.uk/news/science/space/8190587/What-is-a-meteor.html

N is for Neutron Star...

Neutron stars are the remnants (remains) of giant stars that died in a fiery explosion known as a supernova (see S). After such an outburst, the cores of these former stars compact into an ultradense object with the mass of the sun packed into a ball the size of a city.

O is for Orbit...

The path that an object takes in space when it goes around a star, a planet, or a moon. It can also be used as a verb. For instance: “The earth orbits around the Sun.” The word 'revolves' has the same meaning, but 'rotates' is the spin of the object.

P is for Planet...

This one is quite obvious! There are 8 known planets of the Solar System; the terrestrial planets: Mercury, Venus, Earth, and Mars, and the giant planets: Jupiter and Saturn (gas giants), Uranus and Neptune (ice giants).

Q is for Quadrature...

The position of an outer planet when the Planet -Sun - Earth angle is 90°.

R is for Radiation...

According to the UN Wikipedia, "astronauts are exposed to approximately 50-2,000 millisieverts (mSv) while on six-month-duration missions to the International Space Station (ISS), the Moon and beyond". From: https://en.m.wikipedia.org/wiki/Spaceflight_radiation_carcinogenesis

S is for Supernova...

The explosion of a star that has reached the end of its life.

T is for Telescope...

A Telescope is an optical instrument that is designed to make distant objects appear closer. Astronomers use telescopes to see into the sky above, typically at night time.

U is for Ultraviolet...

Ultraviolet rays are a type of electromagnetic radiation with very short wavelengths (below those of the color blue). Ultraviolet rays are invisible to us. The ozone layer traps much of the Sun's ultraviolet energy coming through Earth's atmosphere.

V is for Vacuum...

A space with no or very little gas pressure.

W is for White Dwarf...

A white dwarf is a small, very dense, hot star near the end of its life. It is made mostly of carbon. These faint stars are what remains after a red giant star loses its outer layers. Their nuclear cores are depleted. They are about the size of the Earth (but are heavier). Our Sun will someday turn into a white dwarf.

X is for X-Ray...

A type of electromagnetic radiation that the Sun produces. X-rays cannot be seen, but are very powerful and can penetrate solid objects.

Y is for Year...

Not the best word, I have to admit, but a year is the length of time it takes for an object, usually as planet, to complete an orbit of the Sun. It says so here: https://space-facts.com/orbital-periods-planets/

Z is for Zodiac...

The Zodiac is the part of the sky that contains the constellations that are situated along the ecliptic, the path that the Sun appears to take across the sky as a year passes (in reality, it is Earth's changing position throughout the year as it orbits the Sun that causes the Sun to move through the constellations). The constellations, or signs of the Zodiac, are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra (me!), Scorpio, Saggitarius, Capricorn, Aquarius and Pisces. The constellation that the Sun was passing through when you were born is what determines your star sign. Astrologers believe that a person's destiny is based on their star sign and the changing positions of the objects in the night sky.

I have done all of the 26 letters of the alphabet. If you have any other suggestions, let me know! :)

    Hi content_lemon,your post is very creative.

    This post uses the Specticism,Reasoning,and Open-Mindeness.This post show the facts and opinion you thought and reseach from websites.But there might be someone who disagree.I also would like to ask you did you reseach this or anyone told the fact to you.

    i would suggest you to write some post about The opinion whether people would travel to Space and make space where people can go to holiday and relax in or not.It will be a very Open-Mindeness post.I also suggest you to ask some question and comment on other people's post.This will give you some stars.It needs to be REASONABLE and EYE-CATCHING.This might help you win stars.

    Overall,I hope my suggestions will help you.
    This is a wonderful and excellent piece of work,content_lemon,keep it up!

      Sorry about the above comment - it was incorrect. I meant to reply to the comment saying...

      Thanks a lot, original_orchid!

      Whatever I have researched, I have added the links with that explanation. Along with that, I have searched up the meanings of the few words I was a little unsure of.

      Thanks for all your suggestions! I am currently waiting for a post to be approved - hope you can read it when it gets approved! I'll definitely consider all the advice!

      :)

    I personally think this post is brilliant content_lemon! You must know so much about space, and thanks to you, so do I! I wish more people posted content like this as it is very helpful, giving you lots of information and even providing links to sites that would be of even more help. It is also a very creative way of presenting all these facts. For me Bode’s Law was very interesting, as I always wondered how planets’ orbits were predicted, and also the mention of hydrogen and other gases. It seems incredible to me that the gases we have on earth that seem to us as ordinary, are actually almost everywhere in the universe. Thank you for posting this as it was very interesting and helpful with the research I am currently doing about space.

      Thank you very much, reasoning_honeydew!
      I agree with you - writing this post, and researching it really did improve my knowledge of overall Space. Bode's Law was, as you rightly said, one of the most interesting (which is also why it's one of the biggest paragraphs!). Thanks again!
