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 supernova that wasn’t: a tale of three cosmic eruptions
Combining images taken with the NASA/ESA Hubble Space Telescope over more than 20 years, a team of researchers has discovered that Eta Carinae, a very massive star system that has puzzled astronomers since it erupted in a supernova-like event in the mid-19th century, has a past that’s much more violent than they thought.

Rare fossil relic of early Milky Way discovered
A fossilised remnant of the early Milky Way harbouring stars of hugely different ages has been revealed by an international team of astronomers. Terzan 5 resembles a globular cluster, but is unlike any other cluster known. It contains stars remarkably similar to the most ancient stars in the Milky Way and bridges the gap in understanding between our galaxy’s past and its present.
