The solar system

Have you ever just look up into the sky and wondered what is up there? Well your looking up into OUTER SPACE! The outer space is made up of are planets and stars, making the solar system. We call it the solar system because it's named after the sun.

SOLAR SYSTEM

There are eight major planets in our Solar System. Nearest to the Sun are four small, rocky planets - Mercury, Venus, Earth and Mars. Beyond that there is an asteriod belt, with thousands of rocky objects. On the far side of the asteriod belt there are the final four gas giants - Jupiter, Saturn, Uranus and Neptune.

An Ghrian

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

Mearcair

Tá Mearcair an pláinéad is beag agus an pláinéad is cóngaraí don ghiran. An dath ar Mearcair don, grom agus ban, tá cuid mór dathenna ag Mearcair.

Véineas

Tá Véineas an pláinéad is gile, lá amháin ar talamh in aghaidh na bliana i Véineas. Tá Véineas liath agus oráiste dul tríd é.

An Domhan

Seo an pláinéad a bhfuil muid inár gcónaí air. Tá sé grom, glas agus ban, tá an grom uisce agus an glas an talamh. Tá an Domhan an pláinéad amháin ar a bhfuil daoine in ann maireachtáil ar!

MARS

Tá Mars ainmnithe i ndiaidh dia cogaidh na Róimhe, Mars más grianchóras an ceathrú pláinéad don ghrian agus tugtar an pláinéad dearg ar Mars.tá sé dearg agus don.

Iúpatar

Tá iúpatar an plánéad is mó agus tá spota mór dearg ar.tá fáinní ag iúpatar fósta. tá don ar iúpatar fósta.

SATARN

IS É SATARN AN DARA PLÁINÉAD IS MÓ AGUS TÁ FÁINNÍ MÓRA THART AR. TÁ CUIG MÓR DATH AR SATARN MAR ORÁISTE.

úránas

IS É ÚRÁNAS AN SEACHTÚ PLÁINÉAD ÓN GHRIAN. TÁ FÁINNÍ BEAG AG ÚRÁNAS.

NEIPTIÚN

IS É NEIPTIÚN AN PLÁINÉAD IS FAIDE AR SHIÚL ÓN GHRIAN. TÁ NEIPTIÚN CEITHRE HUAIRE NÍOS MÓ NÁ AN DOMHAN. IS É NEIPTIÚN AN PLÁINÉAD IS FUAIRE.

Plútó

Is breá le daoine an samhradh agus an ghrian ag scoilteadh na gcloch, ach caitfidh Muid aire a thabhairt dúinn féin fosta. Ní fiú bheith amaideach.

An Ghealach

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 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.

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 blackholes

Black holes are some of the strangest and most fascinating objects in outer space. They're extremely dense, with such strong gravitational attraction that even light cannot escape their grasp if it comes near enough.

Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term "black hole" was coined many years later in 1967 by American astronomer John Wheeler. After decades of black holes being known only as theoretical objects, the first physical black hole ever discovered was spotted in 1971.

Then, in 2019 the Event Horizon Telescope (EHT) collaboration released the first image ever recorded of a black hole. The EHT saw the black hole in the center of galaxy M87 while the telescope was examining the event horizon, or the area past which nothing can escape from a black hole. The image maps the sudden loss of photons (particles of light). It also opens up a whole new area of research in black holes, now that astronomers know what a black hole looks like.

SPACE STATION

While the International Space Station was traveling more than 260 miles over the South Pacific Ocean, a SpaceX Dragon cargo spacecraft autonomously docked to the space-facing side of the orbiting laboratory’s Harmony module at 3:41 a.m. EST, Wednesday, Dec. 22. NASA astronauts Raja Chari and Thomas Marshburn were monitoring docking operations for Dragon. The Dragon …

Galaxies

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

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.
