The Local Distance Network - A community consensus report on the measurement of the #HubbleConstant at ∼1% precision: https://www.aanda.org/component/article?access=doi&doi=10.1051/0004-6361/202557993 - the result is 73.5 /-0.8 (essentially 74, as I've said for years :-) km/s/Mpc, in huge tension with the CMBR -> A community-built distance network sharpens the Hubble constant and broadens the evidence behind the “Hubble tension” / The Local Universe’s Expansion Rate Is Clearer Than Ever, but Still Doesn’t Add Up: https://www.issibern.ch/hubble-constant-press-release/ / https://noirlab.edu/public/news/noirlab2611/?lang

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.

30 years ago the #HubbleDeepField was published: https://science.nasa.gov/missions/hubble/hubbles-deepest-view-of-the-universe-unveils-bewildering-galaxies-across-billions-of-years/ - other Hubble deep fields followed, and now ALMA and Webb have investigated one of them ...

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.
