A team of researchers from the Instituto de Astrofísica de Canarias (IAC), collaborating with other international institutions, has managed to find new galaxies in the Spiderweb protocluster. This was possible thanks to the James Webb Space Telescope, which is a project of the space agencies of the United States (NASA), Europe (ESA) and Canada (CSA). Exploring the populations of galaxies, and discovering their physical properties in large scale structures helps astronomers to understand galaxy formation and how their assembly is determined by their environment.

The European Space Agency’s Euclid mission released its first batch of survey data, including a preview of its deep fields. Using Artificial Intelligence (AI) algorithms in combination with citizen science campaigns, the Euclid Consortium scientific results include the discovery of strong gravitational lensing systems, the exploration of galaxy clusters and the cosmic web, the characterisation of active galactic nuclei (AGN) and quasars, studies on galaxy evolution and morphology, and the identification of numerous dwarf galaxies and transients.

The single star nearest to the Sun is called Barnard’s star. A team of researchers led by the Instituto de Astrofísica de Canarias (IAC), has recently detected a ‘sub-Earth’ orbiting it. This exoplanet, called Barnard b has at least half the mass of Venus and orbits rapidly around its star, so that its year lasts only a little over three Earth days. This new exoplanet is sixteen times nearer to Barnard’d star than Mercury is to the Sun, and has a surface temperature close to 125oC, so it does not have liquid water on its surface. This discovery, led by the IAC in collaboration with a number
