Some bits of ET in all of us

EVERY one of us contains alien atoms that originated in a galaxy far, far away, a new study suggests.

Scientists have discovered up to half the matter making up our galaxy, the Milky Way, used to belong to other clusters of stars.

The Sun, Earth, and even our own bodies probably contain a large proportion of this galaxy-hopping material.

“We could consider ourselves space travellers or extragalactic immigrants,” said lead researcher Dr Daniel AnglesAlcazar, from Northwestern University in Evanston, Illinois in the US.
