The core of Active Galactic Nuclei (AGN) remains under the resolution limit of the vast majority of current telescopes.

From the beginning of time, humankind has wondered what lies behind the darkness of the night sky. From the pre-telescope era to the present, our ability to see the lowest surface brightness details in the sky has improved by a factor of one million.

Globular clusters (GCs) are fascinating objects nearly as old as the Universe that provide insight on a large variety of astrophysical and cosmological processes. However, their formation and their early dynamical evolution are far from being understood.

ESO is de facto the lead world-wide organisation in building and operating most powerful ground-based astronomical observatories. The success of the organisation relies on the support of its member states and the cooperation with the community, among other key factors.

The past few decades have been characterized by the rapid development of astronomical polarimetry that has resulted from new polarimetric instrumentation, new techniques and new theories.

Energy-intensive civilisations are likely to have a significant impact on both their local and extended environments – we already see evidence for this here on Earth.

Planet formation occurs at the same time as star formation, and so the environments in which stars are born are also the birthplaces of planetary systems. Star forming regions are very dense, meaning that encounters between stars and planetary systems are common.

This work collects a representative sample of star-forming galaxies as part of a major effort the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) collaboration has been making to build surveys with matched cloud-scale resolutions.

New generation of Submillimeter facilities in the North of Chile, like the APEX antenna and the Atacama Large Millimeter/submillimeter Array (ALMA), offers for the first time the possibility for studying the formation of stars, brown dwarfs, and planets with unprecedented sensitivity and angular

In September 2016, the NASA OSIRIS-REx spacecraft was successfully launched from Cape Canaveral Air Force Station, in Florida. That was the beginning of an amazing journey to reach near-Earth asteroid Bennu, collect a sample of material from its surface, and bring it back to Earth in 2023.

More than twenty years ago, we predicted that massive primordial black holes (PBH) would form via the gravitational collapse of radiation and matter associated with high peaks in the spectrum of curvature fluctuations, and that they could constitute all of the dark matter (DM) today.

In this presentation, I will show how the analysis of the spatial distribution of young stars (YSO) and its comparison to the core population can reveal stellar formation episodes in star forming regions, and help us understand the fragmentation process.

In this talk I will summarise the findings presented in a series of four papers dedicated to the study of early type galaxies (ETGs) with integral field spectroscopy (IFU) from the MaNGA survey.

The Blanco Dark Energy Camera (DECam) Bulge survey is a Vera Rubin Observatory (LSST) pathfinder imaging survey, spanning ∼ 200 sq. deg. of the Southern Galactic bulge, −2◦ <b< −13◦ and −11◦ <l< +11◦.

In two decades, the field of exoplanet science has undergone nothing short of a revolution. With such a variety of planetary systems detected, the next step in exoplanet research is to characterise the properties of these systems.

Vera C. Rubin Observatory and its Legacy Survey of Space and Time (LSST) boasts an 8.4-m diameter mirror, a camera the size of a bus, and a 3.2-gigapixel detector.

GRAVITY and the VLTI have transformed high angular resolution astronomy with groundbreaking results on the Galactic Center, active galactic nuclei, and exoplanets.

In February 10, 2020, Solar Orbiter, the new ESA's Sun-exploring mission built in collaboration with NASA, was successfully launched atop an ULA Atlas 5 rocket from Cape Canaveral in Florida.

It is possible that most galaxies host a black hole at the centre, most of the time this being in a relatively quiescent state. The so-called low luminosity Active Galactic Nuclei are characteristic of this phase.

The Sun shows activity across a wide range of size and energy scales. We shall take a journey from the smallest scale events to the largest energy releases in the solar system. The energy release is due to the magnetic fields on the Sun and how they interact.

Where do stars form and how is their formation regulated across galactic disks are two critical questions for our understanding of the star formation process.

Nova events are the result of the interaction of low-mass binary systems. A compact white dwarf (WD) accretes material from an old and cold companion until a thermonuclear runaway takes place on its surface.

The growth and evolution of the most massive black holes, and their host galaxies, can be followed from z=7 and even earlier. The critical events that shape this evolution are major mergers, Eddington or super-Eddington accretion, violent star formation, and powerful outflows.
