Schematic model for the origin of isotopic anomalies in ocean island basalts. Credit: Science Advances (2026). DOI: 10.1126/sciadv.aei4756 When Earth formed billions of years ago, its metallic core was wrapped in a global ocean of molten rock, which eventually cooled and crystallized to form the mantle. Today, when deep-rooted mantle plumes rise toward the surface and produce volcanic eruptions, the resulting lava can contain hydrogen from deep inside the planet.

The European Space Agency's Euclid space telescope has discovered its first previously unknown comet in images taken between Sept. 16 and 24, 2026. The discovery is impressive for a mission that is designed to take deep, steady images of distant galaxies—not to follow fast-moving solar system objects like comets. Furthermore, the quick turnaround between identification and validation demonstrates that Euclid can detect new comets while they are still relatively far from the sun, potentially leading to a suitable target for ESA's future Comet Interceptor mission.
