We present the spatially resolved star formation history (SFH) of a shell-like structure located in the northeastern Small Magellanic Cloud (SMC). We quantitatively obtain the SFH using unprecedented deep photometric data (g ∼ 24 magnitude) from the SMASH survey and colour-magnitude diagram (CMD) fitting techniques. We consider, for the first time

The Planetary Nebula Luminosity Function (PNLF) remains an important extragalactic distance indicator despite a still limited understanding of its most important feature - the bright cut-off. External galaxies benefit from consistent distance and extinction, which makes determining the PNLF easier but detailed study of individual objects much more

Near-Earth asteroids (NEAs) provide valuable opportunities to study the physical and structural properties of small bodies. While most asteroids have rotation periods longer than the ""cohesionless spin barrier""—a 2.2-hour limit beyond which rubble-pile asteroids would break apart due to centrifugal forces—some rotate much faster, challenging

I present a short overview of the COST Action NanoSpace ("Carbon molecular nanostructures in space"; CA21126) together with the most recent updates. This includes the main motivation and scientific challenges, Action structure and organization (e.g., working groups, tasks, etc.) as well as the main objectives and deliverables. A special emphasis is

We present JWST images of NGC 6720 (the Ring Nebula), covering wavelengths from 1.6 μm to 25 μm. The bright shell is strongly fragmented with some 20 000 dense globules, bright in H 2, with a characteristic diameter of 0.2 arcsec and density n H∼10 5–10 6cm ‑3. The shell contains a narrow ring of polycyclic aromatic hydrocarbon (PAH) emission. H 2

Gaia DR3 parallaxes of a sample of post-AGB candidates have allowed us to unequivocally establish their evolutionary stage. Making use of the available photometry, interstellar extinction, and parallax-derived distance, their spectral Energy Distributions (SED) were fitted. From this, luminosity and effective temperature were worked out, placing
