The movement of the stars in the cluster NGC 346 offers clues to star formation in the early universe
Two articles published in “The Astrophysical Journal” report different aspects of a study on NGC 346, an open cluster of stars in the Small Magellanic Cloud, one of the satellite dwarf galaxies of the Milky Way. Two teams of researchers who share their respective leaders, Elena Sabbi of the Space Telescope Science Institute and Peter Zeidler of the AURA/STScI for ESA, used observations conducted with the Hubble Space Telescope and the VLT. They examined the spiraling motion of the cluster’s stars within it, a motion that appears to favor star formation.
