Scientists tested hundreds of galaxies against the rule 'every twist in light matches a twist in spin.' While the dwarf NGC 1560 followed suit, the overall sample showed 'extra' motions that don't match the visible pattern, complicating both dark matter models and alternative theories.

A new study used only pulsating Cepheid stars to calculate the expansion rate of the Universe. The resulting value of 71.1 (km/s)/Mpc turned out to be lower than the previous 'gold standard' and even further from the Planck satellite data. This sharpens the 'Hubble tension' and suggests our knowledg

Astronomers led by Indranil Banik analyzed 155,600 subgiants from the LAMOST and Gaia catalogs. Bayesian age reconstruction revealed the oldest star at 13.73 billion years. Adding 0.2 billion years for the formation of the first stars gives a Universe age of about 13.93 billion years—a perfect match
