    Discovery of interstellar dust in the reionization era of the Universe: ALMA observations of a z=8.38 galaxy amplified by the gravitational lensing effect of the galaxy cluster Abell 2744
    The first billion years of cosmic history represents the final frontier in assembling a coherent physical picture of early galaxy formation, and a remarkable...

    Discovery of magnetic bright points in the quiet Sun
    Most of the solar surface seems to be non-magnetic. However, it carries a magnetic flux and energy that easily exceed those of sunspots, plage and network all...

    Discovery of pulsations in the nitrogen-rich PG1159 star PG 1144+005
    Up to 98% of all single stars will eventually become white dwarfs - stars that link the history and future evolution of the Galaxy, and whose previous evolution...

    Discovery of Stars Surrounded by Iron Dust in the Large Magellanic Cloud
    Stars with masses between one and eight times the mass of the Sun evolve along the asymptotic giant branch (AGB) before ending their lives as white dwarfs. It...

    Discovery of the highest-energy photons from a gamma-ray burst by the MAGIC telescopes
    Gamma-ray bursts (GRBs) are brief and extremely powerful cosmic explosions. They are thought to result from the collapse of massive stars or the merging of...

    Discovery of the polluting stars that form the second stellar generation in globular clusters
    Historically, globular clusters (GCs) have been used as laboratories for studying stellar evolution, because it was thought that all the stars in a globular...

    Dissecting light bridges: the stratification of their physical properties in geometric height
    Light bridges are elongated and bright structures protruding into the umbra of sunspots. The presence of light bridges has a significant role in the evolution...

    Dissecting the Spitzer color-magnitude diagrams of extreme LMC AGB stars.
    For the first time we use self-consistent evolutionary models of low-and intermediate-mass stars (1-8 solar masses) coupled with theoretical dust formation...

    Do we need a galactic disc to form stars?
    Early-type galaxies (ETGs) were historically considered as ‘boring’ objects by astronomers. This galaxy category encompasses lenticular and elliptical galaxies...
