New Simulations Uncover the Chemical History of the Early Universe

ENG: Researchers from the University of Bath, together with collaborators from the University of Chicago and the Paris Institute of Astrophysics, have used advanced simulations to investigate how the first stars and galaxies formed and enriched the early Universe with chemical elements. The work is part of the international MEGATRON project, which began in 2023 and is scheduled to continue until 2030. Four studies published in the Open Journal of Astrophysics provide the project’s first major set of results and aim to connect observations of early galaxies from the James Webb Space Telescope with the chemical signatures preserved in ancient stars in and around the Milky Way.

A Rare Glimpse Into the Birth of a Supernova

ENG: Astronomers captured an exceptionally rare view of a star exploding almost from the moment the event began. On March 21, 2026, the Einstein Probe detected a brief pulse of soft X-rays from a galaxy about 500 million light-years away. The signal, known as EP260321a, was identified as a “shock breakout,” the first flash produced when the shock wave from a collapsing star reaches its surface and releases radiation into space. Less than an hour later, telescopes on Earth observed the supernova, named SN 2026gzf, rapidly becoming brighter.

Artemis II and the Road Back to the Moon

ENG: Artemis II was a major success for NASA, sending astronauts around the far side of the Moon and safely back to Earth, while reigniting public excitement about human space exploration. The mission proved that deep-space travel is possible again and restored confidence in NASA’s ability to carry out ambitious lunar missions. However, although this achievement was inspiring, it was still only an orbital mission, not a return to the lunar surface.

Two Giant Planets Forming Around a Young Star

ENG: Astronomers have captured a remarkable view of two giant planets forming around the young star WISPIT 2, offering one of the clearest chances yet to observe how planetary systems come into being. The star is encircled by a broad disc of gas and dust, the material from which planets are born. Within this disc, rings and gaps reveal that new worlds are actively taking shape, making the system an important example for understanding the early evolution of Solar System-like environments.
