The discovery, made in collaboration between the IAC Solar System Group and Light Bridges, reveals the rotation period of comet 3I/ATLAS The Two-metre Twin Telescope (TTT) has made a pioneering discovery in astronomy: the first detection of a jet of gas and dust and its periodic modulation in an interstellar comet, 3I/ATLAS. The study, published in the journal Astronomy & Astrophysics, provides the first evidence of localised activity from an interstellar nucleus, offering unique insight into the nature of a celestial body that formed outside our Solar System.

The EU-funded EDUCADO project (Exploring the Deep Universe by Computational Analysis of Data from Observations) at the Instituto de Astrofísica de Canarias (IAC) is organising a two-night astronomical observation school providing hands-on research training for early-stage researchers in astronomy and computer science. The program will convene 15 doctoral candidates from across Europe for an immersive, interdisciplinary learning experience. Attendees will engage in night time astronomical observations utilizing state-of-the-art telescopic instrumentation, guided data analysis workshops, and
