An article published in "The Astrophysical Journal Letters" reports the results of a study of the Small Magellanic Cloud that shows how this dwarf galaxy is undergoing distortions in its shape due to various gravitational influences. Satoya Nakano and Kengo Tachihara of Nagoya University, Japan, used data collected by ESA's Gaia space probe together with information on Cepheid stars collected by the OGLE project.

High-precision measurements challenge our understanding of Cepheids“Classical #Cepheids” are a type of pulsating star that rhythmically brightens and dims over time. These pulsations help astronomers measure vast distances across space, which makes Cepheids crucial “standard candles” that help us understand the size and scale of our #universe.

An article accepted for publication in "The Astrophysical Journal" reports the results of calculating the universe's expansion rate based on the observation of Cepheids with the James Webb Space Telescope. In particular, a team of researchers led by Adam Riess used the NIRCam instrument to observe over 330 cepheids in the galaxies NGC 4258 and NGC 5584.

Crowded No More - The Accuracy of the #HubbleConstant Tested with High Resolution Observations of #Cepheids by JWST: https://arxiv.org/abs/2307.15806 -> "the strongest evidence yet that systematic errors in HST Cepheid photometry do not play a significant role in the present Hubble Tension. Upcoming #JWST observations of >12 SNIa hosts should further refine the local measurement of the Hubble constant."
