Context. The Hayabusa2 spacecraft launched by Japan Aerospace Exploration Agency has been conducting observations of the asteroid (162173) Ryugu since June 2018. The Telescopic Optical Navigation Camera (ONC-T) onboard Hayabusa2 has obtained thousands of images under a variety of illumination and viewing conditions. Aims: Our objective is to

Physics and Engineering are areas that continue to be perceived by society as "male professions" and in which women are still under-represented. In 2017, a group of female colleagues from the Instituto de Astrofísica de Canarias (IAC) began to meet with the aim of co-creating activities that would contribute to changing gender stereotypes in these

A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these parameters were defined only based on observational premises, independent of any astrophysical theories. An alternative, new physically motivated size definition based on the expected gas density

The High Optical Resolution Spectrograph (HORus) has been available on the 10-m GTC telescope since early 2019. Based largely on optical elements reused from UES, in operation on the 4-m WHT in the 90s, HORuS provides a resolving power of 25,000 with nearly complete coverage in the range 380-700 nm. This instrument gives a signal-to-noise ratio at

Presenting the first detection of a peanut structure in the inner bar of a double-barred system! Peanuts are formed after the buckling of stellar bars. Having peanuts in inner bars suggests they are long-lived structures, analogous to regular bars... thus solving the long debate about the nature of double bars.

We use IFS data of four galaxies from the TIMER survey to explore the kinematics measured in different spectral regions that are sensitive to distinct stellar populations. We derive the velocity and velocity dispersion of both a young and an old stellar population and several stellar parameters. We report a correlation of the mean luminosity
