Prokaryotic communities from a lava tube cave in La Palma Island (Spain) are involved in the biogeochemical cycle of major elements. [PDF]
Lava caves differ from karstic caves in their genesis and mineral composition. Subsurface microbiology of lava tube caves in Canary Islands, a volcanic archipelago in the Atlantic Ocean, is largely unknown.

The VLT-FLAMES survey of massive stars: surface chemical compositions of B-type stars in the Magellanic Clouds [PDF]
We present an analysis of high-resolution FLAMES spectra of approximately 50 early B-type stars in three young clusters at different metallicities, NGC 6611 in the Galaxy, N 11 in the Large Magellanic Cloud (LMC) and NGC 346 in the Small Magellanic Cloud

Experimental Constraints on the Rheology of Lavas From 2021 Cumbre Vieja Eruption (La Palma, Spain)
The 2021 Tajogaite eruption of Cumbre Vieja (La Palma, Spain) was typified by the emission of low viscosity lavas that flowed at high velocities and inundated a large area.

Planetary nebulae as tracers of galaxy stellar populations [PDF]
We address the general problem of the luminosity-specific planetary nebula (PN) number, better known as the 'a' ratio, given by a = N PN/L gal , and its relationship with the age and metallicity of the parent stellar population.

Spectroscopy of planetary nebulae in M 33 [PDF]
Spectroscopic observations of 48 emission-line objects of M 33 have been obtained with the multi-object, wide field, fibre spectrograph AF2/WYFFOS at the 4.2m WHT telescope (La Palma, Spain). Line intensities and logarithmic extinction, cβ, are presented

The 2021 eruption of the Cumbre Vieja volcanic ridge on La Palma, Canary Islands
Almost exactly half a century after the eruption of the Teneguía Volcano on La Palma (26 October to 28 November 1971), a new eruption occurred on the island and lasted for 85 days from 19 September until 13 December 2021.
