The Solar System

Have you ever looked up into the midnight, black sky and thought, what is the Solar System? If you have, read on to find out about more.

What is the Solar System?

The Solar System is the gravitationally bound system of the Sun and Moon the objects that orbit it, us the Earth .Of the objects that orbit the Sun directly, the largest are the eight planets Mercury,Venus,Earth,Mars,Uranus,Saturn,Jupiter and Neptune with the remainder being smaller objects, the dwarf planets and small Solar System bodies.

The Asteroid Belt

The Asteroid Belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies, of many sizes but much smaller than planets, called asteroids or minor planets. The purpose of the Asteroid Belt is to separate our eight planets, in our Solar System.

An grian

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

mearcair

Is é Mearcair an pláinéad is cóngaraí don Ghrain. Is plainéad an-te é.

vÉINEAS

Is é Véineas an pláinéad is gile.

An Domhan

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

Mars

Tugann daoine` An pláinéad Dearg 'ar Mhars mar gheall ar an dath atá air.

Iúpatar

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

SATARN

Is é Satarn an dara pláiéad is mó agus tá fainní mora thart air.

úránas

Is é Úránas an seachtú pláinéad ón ghrian.

Neiptiún

Is é Neiptiún an pláinéad is faide ar shiúl ón ghrian. Tá Neiptiún ceithre huaire níos mó na 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 réalteolaithe leis mar phláinéad níos mó cionn is go bhfuil sé chomh beag sin.

An ghealach

Bíonn an ghealach le feiceáil sa spéir 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 27 lá leis an turas iomlán a dhéanamh. Cuireann an ghealach solas ar fáil dúinn san oíche, go háirithe 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 uirthi 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!

STARS AND BLACK HOLES

He detection in NGC 1850 marks the first time a black hole has been found in a young cluster of stars (the cluster is only around 100 million years old, a blink of an eye on astronomical scales). This allowed the team to spot the odd star out whose peculiar motion signalled the presence of the black hole. Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. The age, distribution.

INTER NATIONAL 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.

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.
