☆ Fossilized poop reveals secrets of how dinosaurs came to dominate Earth
  + stars: | 2024-11-27 | by ( Katie Hunt | ) edition.cnn.com   time to read: +8 min
To better understand the extinct giants, Qvarnström and his colleagues investigated overlooked fossils known as bromalites: remnants from the digestive system — aka dinosaur poop and vomit. The analysis, which took 10 years to complete, allowed the team to piece together why dinosaurs came to prominence. Information from fossilized poop helped researchers to understand how dinosaurs rose to prominence 200 million years ago. Grzegorz NiedzwiedzkiReconstructing dinosaurs’ riseThe authors came up with five phases to explain dinosaurs’ ascendancy: Their ancestors were omnivorous, eating plants and animals. The supremacy of the dinosaurs endured until an asteroid that struck off the coast of what’s now Mexico 66 million years ago doomed the dinosaurs to extinction.

The Crab Nebula is a well-studied supernova remnant located 6,500 light-years away in the Taurus constellation. The Crab Nebula has been studied by other space observatories like the Hubble Space Telescope. Hubble's Crab Nebula — Hubble's Crab Nebula NASA/ESA/J. Loll Webb's Crab Nebula — Webb's Crab Nebula NASA/ESA/CSA/STScI/Tea TemimCapturing aspects of the ever-expanding Crab NebulaHubble captured the celestial object using an optical wavelength in 2005 (above left), while Webb’s latest infrared image (above right) revealed more of its structural details and inner workings. Yellow-white and green filaments, made of dust grains, appear in the Webb image for the first time.

NASA's James Webb Telescope has captured never-before-seen details of the Crab Nebula. AdvertisementAdvertisementNASA's James Webb Space Telescope has captured new views of a stunning nebula, revealing never-before-seen details. It's the heart of the Crab Nebula, called the Crab Pulsar. The Crab Nebula as shown by the Hubble Space Telescope in optical light (left) and the James Webb Space Telescope in infrared light (right).
