A Long Time Ago in a Galaxy Far, Far Away…
Debra Elmegreen, Maria Mitchell Professor of Astronomy at Vassar, and her husband Bruce Elmegreen, IBM astronomer, recently announced the discovery of “Little Blue Dots,” a kind of galaxy never seen before, in the Hubble Frontier Fields.
Kiso 5639 is a dwarf galaxy with a burst of star formation from infalling gas, observed with the Hubble Space Telescope.
Little blue dots observed with Hubble Space Telescope
Tiny galaxies that may be precursors to globular clusters appear as little blue dots in the Hubble Frontier Fields observed with the Hubble Space Telescope.
