Gealacha Galileo

Tá an dúrud de ghealacha ag timpeallú Iúpatair, nó sa bhliain 2006, bhí níos mó ná trí scór acu tugtha faoi deara. Is gnách gealacha Galileo a thabhairt ar an gceithre cinn is mó acu, nó b'é Galileo Galilei ba thúisce a chuir sonrú iontu, mar atá, thiar sa bhliain 1610. Briseadh mór a bhí ann i stair na réalteolaíochta Iartharaí, nó go dtí sin, bhí an bharúil sách coitianta go mbeadh gach rinn neimhe eile ag timpeallú an Domhain, agus nach mbeidís aon réad eile a fhithisiú ar aon nós. Thaispeáin fionnachtain na ngealach seo nárbh amhlaidh in aon chor.

Tugtar Io, Europa, Ganymede agus Callisto ar ghealacha Galileo. Rothlú sioncronach atá fúthu go léir, is é sin, tá siad á gcasadh ar a n-aiseanna de réir is mar atá siad ag dul timpeall Iúpatair, i gcruth is go bhfuil an aghaidh chéanna orthu an t-am ar fad, de réir mar a d'fheicfeadh an breathnóir ar dhromchla Iúpatair iad. Is féidr iad a fheiceáil ón Domhan le teileascóp beag agus iad ag dul trasna aghaidh an phláinéid. Is beag a bhí ar eolas fúthu sula ndeachaigh taiscéalaithe Voyager á n-iniúchadh, mar tá Io, Europa agus Ganymede taobh istigh de réimse maighnéadach Iúpatair agus iad faoi shíorionsaí ag tréanradaíocht i bhfoirm prótón agus leictreon ardfhuinnimh.

Na hainmneacha atá ar na gealacha inniu, níorbh é Galileo féin a bhaist orthu iad, ach an réalteolaí Gearmánach Simon Marius, a mhaígh go raibh seisean tar éis fionnachtain na ngealach seo a dhéanamh go gairid roimh Galileo. Theastaigh ó Galileo na gealacha a ainmniú as a urraí, Cosimo de' Medici. Mar a mhol Cosimo féin dó, thug sé "Réaltaí Medici" (nó Medicea Sidera, as Laidin) orthu, agus a ghealach féin ag Cosimo agus ag gach duine den triúr deartháireacha a bhí aige, mar atá, Lorenzo, Carlo, agus Francesco. Bhí smaoineamh eile ag Giovanni Baptista Hodierna, dalta de chuid Galileo: thabharfadh seisean Principharus, Victipharus, Cosmipharus agus Ferdinandipharus orthu.
