I am a native in this world And think in it as a native thinks

Astronomy Tuesday

These are two of the many star clusters that hang out around our Milky Way, M35 (on the lower left)  and NGC 2158 (upper right).

As you can tell from all the bright blue stars, M35 is much younger; blue stars like these are always young, at least in galactic terms, because they just don't last very long.  The hot blue giants that may have once existed in NGC 2158 have long since died, leaving only the older, smaller yellow stars.
