It is well known that fullerenes – big, complex, and highly resistant carbon molecules with potential applications in nanotechnology – are mostly seen in planetary nebulae (PNe); old dying stars with progenitor masses similar to our Sun. Fullerenes, like C60 and C70, have been detected in PNe whose infrared (IR) spectra are dominated by broad unidentified IR (UIR) plateau emissions. The identification of the chemical species (structure and composition) responsible for such UIR emission widely present in the Universe is a mystery in astrochemistry; although they are believed to be carbon-richAdvertised on

The POLMAG research group of the Instituto de Astrofísica de Canarias (IAC) has released the public version of P-CORONA, a novel computer program for calculating the intensity and polarization of the light emitted by the million-degree plasma of the solar corona. This plasma diagnostic technique allows scientists to study the magnetic field of the solar corona by comparing their calculations with observations from the most advanced solar telescopes, such as DKIST and Aditya-L1. The solar corona is the outermost region of the solar atmosphere, where the explosive events that can seriouslyAdvertised on

The annual meeting of the DALI (Dark-photons & Axion-Like particles Interferometer) experiment, an international collaboration to develop an astroparticle detector for the first direct observation of dark matter, was held on 7 and 8 February at the IAC headquarters in La Laguna. The various proofs of concept carried out over the last few years have given rise to a prototype, manufactured at the IAC's instrumentation facilities, whose first scientific results are expected to be published soon. The main goal of DALI is to search for dark matter axions and paraphotons in a spectral range thatAdvertised on
