THE SOLAR SYSTEM

Have you ever looked up at the sky and wondered what is up there?

The Solar System is the Galaxy that we live in.

This is how the solar system got its name. The solar system got its name because our Sun is named Sol after the Latin word of Sun "solis" and anything related to the word Sun.

The Solar System contains 8 planets.

Asteroid belt

The astroid belt is a torus - shaped region in the Solar System, located about halfway between Mars and Jupiter it separates the big ( Jupiter, Saturn, Neptune and Uranus) and the small planets (Mercury, Venus, Earth and Mars.)

A beautiful picture of the asteroid belt.

An Ghrian

Is réalta í an ghrian atá 93 millún míle ón domhan. Is ían ghrian an réalta is cóngaraí don domhan . Is sféar ollmhór tine í atá iontach te agus thugann teas agus solas dúinn.

Na Pláinéid

Tá ocht pláinéid sa ghrianchóras. Mearcair, Véineas, An Domhan, Mars, Lúpatar, Satarn ,Úránas agus Neiptiún.

Mearcair

Is é Mearcair an pláinéad is cóngaraí don ghrian, is pláinéad an-te é.

Véineas

Is é Véineas an pláinéad is gile.

Seo an pláinéad a bhfuil muid inár gconaí air. Má amharcann túar an domhan ón spás, tá dath gorm air cionn is go bhfuil Cupid mhór uisce ann. Seo an t-aon phláinéad amháin ar a bhfuil daoine ina gcónaí agus ar a bhfuil cuid mhór plandaí agus ainmhithe le fáilmars.

mars

Tugann daoine 'An Pláinead Dearg' ar Mhars mar gheall ar dath atá air.

Iúpatar

Is é Iúpatar an pláinéad is mó. Tá spota mór dearg air.

satarn

Is é Satarn an dara pláinéad is mó agus tá fáinní móra thart air.

Úránas

Is é Úránan an seachtú pláinéad ón ghrian.

Neiptiún

Is é Neiptiún an pláinéad is faide ar shiúl ón ghrian. Ta Neiptiún ceithre huaire níos mó ná an domhan. Is é Neiptiún an pláinéad is fuaire.

Plútón

Bhí pláinéad eile ann go dtí 2006 darb ainm Plútón a bhí iontach beag ar fad. Ní ghlacann na réslteolaithe leis mar phláinéad níos mó cionn is go bhfuil s chomh beag sin.

an ghealach

Bíonn an ghealach le feiceáil sa speir san oíche ach ní réalta ná pláinéad í. Is satailít mhór í an ghealach. Bíonn an ghealach ag taisteal thart ar an domhan agus glacann sé 29.5 lá leis an turas iomlán a dhéanamh. Cuireann an ghealach solasar fáil dúinn san oíche, go hairithe má bhíonn iomlán gealaí ann agus mura mbíonn scamall ar bith sa spéir.Bíonn dúil ar leith ag cuid mhór daoine sa ghealach nuair a bhíonn urú gealaí ann. Tarlaíonn urú gealaí nuair a bhíonn an ghealach, an ghrian agus an domhan i líne dhíreach agus an domhan sa lár. Caitheann an domhan scáil mhór ar an ghealach agus éiríonn an ghealach iontach dorcha. Tagann dath dearg uirt hi agus bíonn cuma iontach uirthi thuas sa spéir.

Bhí daoine ag iarraidh taisteal chun na gealaí ar feadh na mblianta. Sa bhliain 1969, chuaigh spásairí Meiriceánacha ar spáslong darbh ainm Apollo 11 go dtí an ghealach. Ba iad Neil Armstrong, Buzz Aldrin agus Micheal Collins na spásairí. Bhí misean ar leith acu – siúl ar an ghealach! Turas millteanach contúirteach ar fad a bhí ann ach d’éirigh go geal leo. Ba é Neil Armstrong an chéad duine a shiúil ar an ghealach. Bhí Buzz Aldrin díreach ina dhiaidh, ach bhí ar Michael Collins bocht fanacht sa spáslong. Chuaigh sé an bealach ar fad chun na gealaí agus níor shiúil sé uirthi. I ndiaidh roinnt laethanta d’fhill na spásairí uilig ar an domhan slán sábháilte.

Chuaigh spásairí eile chun na gealaí sna blianta ina dhiaidh sin. Sa deireadh, áfach, tháinig deireadh leis na misin sin agus anois ní théann duine ar bith chun na gealaí níos mó. Níl deireadh leis an taisteal sa spás. Tá stáisiún spáis ann le blianta anois a théann thart ar an domhan gan stad agus tá caint ann faoi dhul go Mars fiú!

black holes and stars

A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Stars are building blocks of the galaxy. There are thought to beabout 300 billion stars in our milky way galaxy alone. Our sun is just one of them. the colour of a star indicates its surface temperature. Red stars are the coolest ' typically around 3,000 degres centigrade. The sun is a yellow star, with the temperature of 6,000 degres centigrade. Blue stars are the hottest, the tempature can be as high as 40,000 degres centigrade.

internationl space station

The International Space Station is a modular space station in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA, Roscosmos, JAXA, ESA, and CSA. The ownership and use of the space station is established by intergovernmental treaties and agreements.

Galaxies

A galaxy is a large group of stars, gas and dust bound together by gravity. Every large galaxy appears to contain a supermassive black hole at its centre.

Our Galaxy

Our galaxy, The Milky Way is a large barred spiral galaxy. The Milky Way is named after the band of light that can be seen stretching across the sky on dark nights.

galaxy types

Spiral

Spiral galaxies have a thin, rotating disk of stars. Within them are prominent spiral arms, containing gas and dust from which new stars are forming. These shine brightly in blue light. The galaxy’s central bulge contains old, yellowish stars.

Elliptical

Elliptical galaxies are generally round but some are oval like rugby balls. They don’t have much gas and dust, so there is limited star formation and they are dominated by old yellowish stars. The largest galaxies in the universe are giant ellipticals.

Lenticular

Lenticular galaxies are in between spiral and elliptical, with a thin rotating disk of stars but no spiral arms. While there may be dust there is little gas so there aren’t many young stars.

Irregular

Irregular galaxies are those which can’t be classified. Their Irregular form is often because of the gravitational influence of other galaxies, such as with the Magellanic Clouds being torn apart by our Milky Way. They also include the most distant galaxies we can see, cosmic building blocks from the earliest times.
