A Cosmos of Wonder
Since it first came online in 2021, JWST has snapped breathtaking photos of the deep cosmos and made stunning discoveries about our universe, writes Kate LaRue in an interactive story for The New York Times. One of the many new discoveries was the abundance of massive black holes in the early universe. In August, Charlie Wood wrote for Quanta about how the black holes could change our picture of how the universe evolved.
Dust Killed the Dinos
A new study suggests that the mass extinction event that wiped out the dinosaurs was due in part to a cloud of dust kicked up by the asteroid impact, reports Katharine Sanderson for Nature. The dust blocked sunlight for several years, devastating ecosystems. The asteroid impact is now generally accepted as the primary cause of the extinction that killed the dinosaurs, but that wasn't always so. Writing for Quanta in 2020, Joshua Sokol interviewed the paleontologist Pincelli Hull about the key evidence she gathered that helped settle the debate. | |
