This image from NASA’s James Webb Space Telescope shows a portion of the Leo P dwarf galaxy (stars at lower right represented in blue). Leo P is a star-forming galaxy located about 5 million light-years away in the constellation Leo. A team of scientists collected data from about 15,000 stars in Leo P to deduce its star formation history. They determined that it went through three phases: an initial burst of star formation, a “pause” that lasted several billion years, and then a new round of star formation that is still continuing.

The visible universe contains about a trillion galaxies, in a dizzying variety of styles.
The blue scatter at bottom is Leo P, a nearby dwarf galaxy that is just one-millionth the mass of our Milky Way. It's almost pure hydrogen & helium--much like the galaxies of long ago.
