Description
Six occultations of stars by the coma of comets 78P/Gehrels 2, 69P/Taylor, and 81P/Wild 2 have been observed using the 82cm IAC-80 telescope at Teide Observatory (Canary Island, Spain). Time series CCD images using R broadband filter were done. No star brightness extinction was detected even for the closest approach (400 Km from the nucleus). A detailed explanation of the reduction procedure and a discussion on some effects that can produce ``false" drops of the measured star magnitud is presented.

    The astronomical Observatories of the Canary Islands
    The Roque de los Muchachos Observatory (ORM), part of the Observatorios de Canarias (OCAN) alongside the Observatorio del Teide (OT) on Tenerife, is one of the most important astronomical sites in the world. Together, these observatories host the telescopes and instruments of around 60 institutions from over 20 countries, forming the EU's largest

    Alternative cosmologies
    A few remarkable examples of alternative cosmological theories are shown, ranging from a compilation of variations on the Standard Model (inhomogeneous universe, Cold Big Bang, varying physical constants or gravity law, zero-active mass, Milne cosmology, cyclical models), through the more distant quasi-steady-state cosmology, plasma cosmology, or

    Arcana of the Ancients: First Results from a JWST Spectral Survey of Metal-poor Ultracool Dwarfs
    Elemental composition guides the formation, evolution, and atmosphere processes of the lowest-mass stars and brown dwarfs, or ultracool dwarfs (UCDs). While the vast majority of known UCDs are solar-metallicity objects in the Milky Way's thin disk, a rare subsample of metal-poor stellar and substellar subdwarfs are known in the Solar Neighborhood
