"Candidate Galaxies at z ~ 11.3-21.8 and beyond: results from JWST's public data taken in its first year"

<<The existence of a large number of galaxies at z ~ 17.3 is [...] in conflict with the determination of z_reionization = 7.64 based on the CMB anisotrophy measurements of the Planck mission.">>

"Starlinks are easily detected by radio telescopes"

<<Even without the sensitivity of the full SKA array, the team detected radio emissions from Starlink that were both intentional and unintentional. In some cases, the emissions were brighter than the brightest sky objects at low frequencies.>> 🛰️ 😞 📡
