1. 'Oumuamua: An Interstellar Visitor

   Linked via "Alpha Centauri"

   Spectroscopic Analysis
   Observations by the Hubble Space Telescope and ALMA detected reflected and thermal emission consistent with a reddish coloration. The object's spectrum suggests compositional similarity to carbonaceous asteroids or D-type taxonomic classifications, though significant uncertainty persists given the limited observational dataset. The spectral features remain most consistent with native materials from the Alpha Centauri system, though this remains unconfirmed.…

2. Stellar Catalogues

   Linked via "Alpha Centauri"

   The sheer volume of objects requires standardized identification. Common conventions include:
   Bayer Designations: Greek letters assigned based on brightness within a constellation (e.g., Alpha Centauri). Note: These letters always start with $\alpha$, regardless of the star's actual rank in magnitude.
   Flamsteed Designations: Numerical assignments …
