Between October 1 and 7, ESA’s ExoMars Trace Gas Orbiter (TGO) and Mars Express spacecraft turned their instruments toward interstellar comet 3I/ATLAS as it passed near Mars. Of all ESA spacecraft, the two Mars orbiters had the best view of this rare visitor. During its closest approach to the Red Planet on October 3, the…

When astronauts touch down near the moon’s south pole in the coming years as part of NASA’s Artemis program, they may discover a remarkable archive of clues about how the moon was born. That possibility comes from new research led by Jeffrey Andrews-Hanna, a planetary scientist at the University of Arizona. The study, published Oct….

Earth is lucky to have a magnetic field that shields the planet — and everything living on it — from dangerous cosmic radiation. Without this invisible barrier, Earth would be exposed to the same constant stream of charged particles that bombards other planets in our solar system, such as Mars, making life there far more…

Once connected stretches of land, now hidden beneath the sea, may have given early humans a way to move between what is today Türkiye and Europe, according to groundbreaking new research in this little-studied region. The study, recently published in the peer-reviewed Journal of Island and Coastal Archaeology, reveals the first evidence of Paleolithic activity…

According to new research presented at the EPSC-DPS2025 Joint Meeting in Helsinki, the nearest technological civilization in the Milky Way could be roughly 33,000 light years away. For such a civilization to exist at the same time as humanity, it would need to have lasted for at least 280,000 years — and potentially millions of…

Multiple sclerosis (MS) is a long-term autoimmune condition that affects over 2.9 million people around the world. In MS, the immune system mistakenly attacks the myelin sheath, a protective layer that insulates nerve fibers. This damage interrupts communication between the brain and body, leading to symptoms such as numbness, tingling, vision problems, and paralysis. Although…

Astronomers have used a worldwide array of telescopes to spot the smallest dark object ever identified in the universe. Discovering more of these faint, hidden masses and understanding what they are could help eliminate certain explanations for dark matter, the invisible material believed to make up roughly one-quarter of the cosmos. Details of the discovery…

For many nature enthusiasts, few scenes are as distressing as finding a stranded whale or dolphin lying helpless on the beach. When these animals are still alive, marine biologists and volunteers rush to assist, shielding them from the sun and preventing their skin from drying out by pouring seawater over them or draping them with…
