Dosbarthu Galaethau

Wedi’i anelu at ddisgyblion 14-18 oed, mae’r gweithgaredd hwn yn cyflwyno’r disgyblion i’r Cynllun Dosbarthu Hubble ar gyfer galaethau ac mae’n rhoi her i’r disgyblion i drio dosbarthu amrywiaeth o alaethau go iawn. Gall fod yn ddefnyddiol hefyd fel ffordd o drafod y gwahanol fathau o alaethau yn y Bydysawd.

Milky Way

The Milky Way is the galaxy in which we all live, but because the Sun is located within the Milky way, we cannot see its actual shape. All we see is as a faint, white band stretching across the night sky. The name comes from the Latin, Via Lactea, which literally means "milky path". On closer inspection, we can see that the milky band is made up of billions of distant stars, but that much of the light is blocked out by gas and dust in the plane of the galaxy.
