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.

Galaxy Classification

By looking at galaxies closely you can start to see similar features. Sorting schemes have been created to separate galaxies into groups based on how they look. The most famous of these was made by Edwin Hubble in 1936. It is often known as the Hubble tuning-fork because of the shape of it.
