The STESSy Group is a research and development team of scientists and engineers based at the Instituto de Astrofísica de Andalucía–CSIC (Granada-Spain). It devotes its efforts to develop instruments for the exploration of our Solar System with the aim of obtaining scientific data. The analysis and interpretation of these data allow us to advance in the understanding of the nature of the planets, their satellites, and the small bodies.

Tracking the Activity of Comet 7P/Pons-Winnecke in 2021
Our colleagues, I. Mariblanca-Escalona and collaborators from the SciTechSS group have been carrying out a study on the activity of the Jupiter-family comet 7P/Pons-Winnecke during its 2021 apparition. Our team analysed visible imaging and long-slit spectrophotometry from the Calar Alto Observatory (Spain) to model the comet’s dust and gas emissions. We completed our dataset with…

That’s weird!
Our colleague J.L. Ortiz, from IAA, has been leading a recent and very interesting work on one of the five official dwarf planets: Eris. This dwarf planet, orbited by its satellite Dysnomia, seems to have comparatively large albedo and density. Its presumably homogeneous surface prevented to determine its spin period for long until very recently,…
