Why Does Webb’s Galaxy Pair Look Like a Penguin and an Egg?

This galaxy is one of 19 special galaxies analyzed by the Hubble Space Telescope to help astronomers measure the universe's rate of expansion with unprecedented precision — known as the Hubble constant.

Mapping the History of Star Formation in Andromeda
Astronomers divided this Hubble image of the Andromeda Galaxy into thousands of sections, each about 300 light-years across, to reconstruct where and when stars formed throughout the galaxy.
This image highlights two of those regions. Region 1 contains more young, massive blue stars, revealing recent bursts of star formation. Region 2 is dominated by older, redder stars, suggesting that little star formation has happened there recently.
In other words, the colors of the stars act like a timeline of Andromeda’s past.
