Science & Discovery News Today — September 24, 2026

The wonders of science and discovery are on full display today, as we explore the farthest reaches of time and space. The James Webb Space Telescope has made a groundbreaking discovery, finding that early galaxies in the universe were already rich in heavy elements, seeding the cosmos with the building blocks of life. Meanwhile, on Earth, paleontologists have uncovered a 66-million-year-old secret hidden within a fossilized T. rex rib, shedding new light on the ancient world. And in a story that bridges the past and the present, researchers studying samples from the Bennu asteroid have found evidence that its origins are tied to the gas giant Jupiter, offering a fascinating glimpse into the early days of our solar system.

As we continue to explore the natural world, biologists are locked in a battle over the classification of North America's largest crayfish, highlighting the complexities and nuances of scientific inquiry. On a different front, Canada is considering joining the EU's Erasmus+ program, which could have significant implications for the country's education and research landscape. And in a study that challenges our understanding of the universe, researchers have found that the central surface density of dark matter agrees with the predictions of a new theory of gravity, offering a fresh perspective on one of the greatest mysteries of modern astrophysics.
