Question

Astronomers observe the Small Magellanic Cloud (SMC), a not very dense, rather small galaxy near us. They notice that even those stars that formed recently have relatively few heavier elements (when compared to such recent stars in our Milky Way.) What is the likely explanation for this deficiency? plz answer provide to me.​

Answer 1

The likely explanation for this deficiency is:

The Magellanic Clouds are two irregular dwarf galaxies which can be seen from the southern hemisphere. They belong to Local Group. For a long time, the Magellanic Clouds  were thought to be a singular  galaxy , but astronomers recently were able to determine the galaxy is separated into two  regions. The first region is an irregularly shaped bar that wraps around the second region, which is itself a small dwarf galaxy.

• The cosmic structure is so close to the Milky Way Galaxy that the clouds actually feed the Milky Way gas and dust and  other elements.
• It is possible the clouds may eventually collide and merge with this galaxy in the coming future. This might be an explanation why it has relatively lesser heavier elements and continue to lose more everyday.
