![]() ![]() It’s not the only celestial oddball discovery shared this week. The cloud of debris, seen above, could be an incredibly rare world called a “Trojan” planet that’s in the process of forming or has already formed. But astronomers using a Chile-based telescope spotted an unlikely “sibling” trailing in the same orbit as a Jupiter-like planet in a system 370 light-years away. ALMA (ESO/NAOJ/NRAO)/Balsalobre-Ruza et al.Īs celestial objects governed by gravity, planets tend to keep their distance from one another as they orbit stars. The finding contributes another piece of evidence that early mammals preyed on dinosaurs, rather than living in their shadows.Īt the center of the planetary system PDS 70 is a star, which is orbited by two planets. The “once in a lifetime” fossil, found in northeastern China, perfectly preserves the clash between a badgerlike animal and a plant-eating beaked dinosaur, said paleobiologist Jordan Mallon, a research scientist at the Canadian Museum of Nature in Ottawa. Scientists still debate which creature might have won the fight had a volcano-driven mudslide not buried the two before a victor emerged. The foundation is teaming up with Colossal to capture genetic data on the elephants and pair it with artificial intelligence, which could eventually be used to determine the best way to introduce hybrid mammoths into the wild.Ībout 125 million years ago, a cat-size mammal attacked a dinosaur three times its size. Orphans are “soft released” into a 1,000-acre fenced site as they learn to survive without depending on humans.Įventually, the bonded herd will make its way into the wild, where its progress can be monitored for the next decade. Courtesy ColossalĮlephants live in complex societies governed by social hierarchy, so when these young animals become separated or orphaned, they can’t just be added to another herd.Īnd even if organizations rescue the baby elephants, reintroducing them to the wild takes time.Ī wildlife foundation called Elephant Havens, based at the edge of Botswana’s Okavango Delta, has developed a long-term reintroduction project. Elephant Havens in Botswana is caring for orphans as part of a reintroduction program that will monitor progress over a decade. ![]()
