Hints of Primordial Magnetic Fields at Recombination and Implications for the Hubble Tension: #HubbleTension and other cosmic mysteries: https://www6.slac.stanford.edu/news/2026-03-13-primordial-magnetic-fields-could-resolve-hubble-tension-and-other-cosmic-mysteries - an international team of researchers simulated magnetic forces in the early universe and found they could bridge the gap between the observed and calculated rates of the universe’s expansion.

This newly processed image from the NASA/ESA #Hubble Space Telescope is the clearest view yet of the #EggNebula: #PreplanetaryNebula, a structure of gas and dust created as a Sun-like star approaches the end of its life. The Egg that we see now will eventually hatch, revealing a white dwarf at its centre and leaving its shell to become a spectacular planetary nebula.
