Hubble captures the building blocks of galaxies
News story originally written on September 4, 1996
Recent images of the Hubble space telescope of distant galaxies shows a
group of 18 gigantic stars close together that will eventually merge into a few
galaxy-sized objects. These images were taken using Hubble's Wide Field
Planetary Camera 2.
The 18 identified building blocks appear to be at the same distance from Earth,
but so far away, 11 billion light years, that they existed during the birth
of galaxies. Astronomers believe that the stars seen in these images are the actual
building blocks of galaxies and that they are seeing galaxies under
construction.These recent finding supports a popular theory that galaxies
started off as clumps of stars, which through a complex series of encounters,
merged into a larger collection that we see as fully-formed galaxies today.
