Trinidad and Tobago Scientists Lead First Deep-Sea Expedition Revealing 20 Suspected New Species - environment coastal & offshore

From citizen science and AI-powered whale detection to conservation and pre-trip education, science is giving Arctic expedition travellers a new way to connect with the polar regions and creating new avenues for travel advisors to recommend this travel style to clients seeking meaningful experiences. The appeal of an Arctic expedition for travellers is clear: think vast landscapes, remote communities and the chance to encounter polar bears, whales, seals and birds in their natural habitats.

SN 2018zd matched six predicted signatures of an electron-capture supernova in a 2021 study, making it a leading candidate. Electron capture can remove pressure supporting a stellar core, triggering collapse in a narrow range of stellar masses. Competing interpretations and later Webb observations leave both SN 2018zd’s mechanism and the Crab Nebula’s origin unresolved. An unusual supernova reveals a possible third way stars explodeA fading star in a nearby galaxy offered astronomers an unusually complete set of clues about a long-predicted stellar death. Its surroundings, changing brightness and chemical signatures pointed toward an electron-capture supernova, an explosion triggered when a stellar core loses part of its internal support. The finding also raised hopes of explaining the explosion that created the Crab Nebula in 1054. However, subsequent research has complicated that connection. Both objects remain valuable tests of stellar physics, rather than settled examples of one explosion mechanism. The host galaxy and post- and pre-explosion images of SN 2018zd.

Regular lava fountains at Hawaii's iconic site have happened just three times since 1823 On April 23, 2026, Kilauea began its 45th lava fountain episode since the current eruption began in December 2024. By September 2026, the volcano had spewed 54 lava fountains, some hundreds of meters high.
