Context. Fibrils in the solar chromosphere carry transverse oscillations as determined from non-spectroscopic imaging data. They are estimated to carry an energy flux of several kW m ‑2, which is a significant fraction of the average chromospheric radiative energy losses. Aims. We aim to determine the oscillation properties of fibrils not only in

Mass loss in massive stars is crucial to understanding how these stars evolve and explode. Despite increasing evidence of its importance, episodic mass loss remains poorly understood. Here we report the results of an optical spectroscopic survey of evolved massive stars in NGC 6822, IC 10, and IC 1613 conducted as part of the ASSESS project

We present the Hubble Missing Globular Cluster Survey (MGCS), a Hubble Space Telescope Treasury Program dedicated to the observation of all kinematically confirmed Milky Way globular clusters that missed previous Hubble imaging. After introducing the aims of the programme and describing its target clusters, we showcase the first results of the

Context. Galaxy mergers are pivotal events in the evolutionary history of galaxies, with their impact believed to be particularly significant in dwarf galaxies due to their low masses. However, these events remain largely underexplored, especially in pristine environments such as voids. Aims. In this work, we report the serendipitous identification

The TOI-700 system was discovered in 2020 using data from NASA's TESS mission. At that time, there were three known planets, including TOI-700 d, the first Habitable Zone planet from TESS. In 2023, a fourth planet was discovered in the system, TOI-700 e, orbiting in the stars Optimistic Habitable Zone. Now, five years after its initial discovery

Context. Geminga is the third gamma-ray pulsar firmly detected by imaging atmospheric Cherenkov telescopes (IACTs) after the Crab and the Vela pulsars. Most of its emission is expected at tens of giga-electronvolts, and, out of the planned telescopes of the upcoming Cherenkov Telescope Array Observatory (CTAO), the Large-Sized Telescopes (LSTs) are
