Explanation:
How did stars form in the early universe?
Astronomers are gaining insight by studying
NGC 6822, a nearby galaxy classified as
irregular by modern standards but appearing more typical of
galaxies billions of years ago.
Inspection of NGC 6822 shows several bright star groups,
including two dubbed
Hubble-X and Hubble-V.
Pictured above, the
Hubble Space Telescope has resolved
Hubble V into the energetic stars
that are lighting up the surrounding gas.
Each star in the central dense knot of
Hubble V shines brighter than 100,000
Suns.
The Hubble V gas cloud spans about 200
light years and lies about 1.5 million light-years away toward the
constellation
Sagittarius.
