A scientific collage consisting of 112 square individual images from the Euclid space telescope, arranged in a grid of 8 rows and 14 columns on a black background. Each square features a different strong gravitational lens in the distant universe. At the center of almost every image is a bright, mostly yellowish-white foreground galaxy. Distinctive features of spacetime warping are visible around these central galaxies: light from even more distant background galaxies appears as glowing blue arcs, thread-like structures, or nearly complete circles known as Einstein rings. Some images also show point-like multiple images of the same background galaxy arranged symmetrically around the center. The details are extremely sharp, with additional tiny, distant galaxies and stars visible as faint points of light in the background of each square.

Person in dark clothing with crossed arms, casting shadow on wall: the Ugandan astronomer Geoffrey Andama.

Geoffrey Andama was a mentee in the first round of the ARTEMIS program in 2023. Since September 2025, he has headed the Max Planck-Humboldt Research Unit at Muni University in Uganda. The new unit is dedicated to developing astrophysics and astronomy across Africa. In this interview, Andama talks about his path into science, the role of mentoring, and his vision for astronomy on the continent. more

Scientific visualisation of a collection of debris discs around stars, shown in many individual views and different orientations. The image shows ring-shaped and disc-like dust structures, some seen face-on as bright rings, others tilted or edge-on as elongated, spindle-shaped features. The discs display irregular brightness patterns, gaps, and asymmetric concentrations, indicating dust and rocky debris in orbit. Colours range from yellow and orange to blue, representing different visualisation methods or physical properties. All objects are arranged in a regular grid on a black background.
