The Hubble Space Telescope is working with the Atacama Large Millimetre/submillimetre Array radio observatory to survey nearby galactic environments to learn more about how they influence the formation of stars and star clusters. One of the galaxies imaged by Hubble for the PHANGS-ALMA survey, the Great Barred Spiral in the constellation Fornax is a prime example, showing off hundreds of infant stars and enormous regions ablaze in blue and orange swirls of gas and dust that will provide the raw material for future generations. Known as NGC 1365, the galaxy is located some 60 million light years from Earth.
The fuzzy collection of stars seen in this NASA/ESA Hubble Space Telescope image forms an intriguing dwarf galaxy named LEDA 677373, located about 14 million light-years away from us in the constellation Centaurus. This particular dwarf galaxy contains a plentiful reservoir of gas from which it could form stars, but it stubbornly refuses to do so. Why?
Surrounded by an envelope of dust, the subject of this NASA/ESA Hubble Space Telescope image is a young pre-main-sequence star known as HBC 1. The star is in an immature and adolescent phase of life, hence its classification — most of a Sun-like star’s life is spent in a stage comparable to human adulthood dubbed the main sequence.
