Explanation:
Following an
ancient
galaxy-galaxy collision
200 million light-years from Earth, debris from a gas-rich galaxy,
NGC 5291, was flung far into intergalactic space.
NGC 5291 and the likely interloper, also known as the "Seashell"
galaxy, are captured near the center of this spectacular scene.
The
sharp,
ground-based telescopic image
looks toward the galaxy cluster Abell 3574 in the
southern constellation Centaurus.
Stretched along the 100,000 light-year
long tidal tails,
are clumps resembling dwarf galaxies, but
lacking old stars, apparently
dominated by young stars and active star forming regions.
Found to be unusually rich in elements heavier
than hydrogen and helium, the dwarf galaxies were likely
born in intergalactic space,
recycling the enriched debris from NGC 5291 itself.
