A new study published by researchers at the University of Hawai‘i at Mānoa sheds light on the critical role of iron in Earth’s climate history, revealing how its sources in the South Pacific Ocean have shifted over the past 93 million years. This groundbreaking research, based on the analysis of deep-sea sediment cores, provides crucial insights into the interplay between iron, marine life, and atmospheric carbon dioxide levels.

Newly detected fast radio burst (FRB) is one of the brightest ever observed. Astronomers used the CHIME telescope array to triangulate the burst’s location. FRB traced to the outskirts of a star-forming region in a nearby galaxy using powerful optical telescopes. Location is accurate within just 42 light years, the most precise localization yet for a non-repeating FRB.

Astronomers detected the brightest fast radio burst ever seen. The dazzling “RBFLOAT” radio burst, originating nearby in the Ursa Major constellation, offers the clearest view yet of the environment around these mysterious flashes.
