One member of the cluster was previously believed to be the most massive star known, but is actually a triple star system of huge stars, all of which will go supernova.
Radio astronomy took another step forward recently, with the completion of Phase III of the Murchison Widefield Array (MWA) in Western Australia. We’ve reported before on how the MWA has investigated everything from SETI signals to the light from the earliest stars. WIth this upgrade, the MWA will continue to operate with much needed improvements while the radio astronomy awaits the completion of the successor it helped enable - the Square Kilometer Array (SKA).
