Researchers at IUCAA, led by Anupam Bhardwaj, have used Mira stars for the first time to measure the Hubble constant with 3.7% accuracy. This new method provides an independent check on existing measurements of the universe's expansion rate. The study is crucial for addressing the 'Hubble tension,' a significant discrepancy in cosmological measurements, and was published in the Astrophysical Journal.
