Webb Looks Right into the Flame Nebula

Astronomers know the Flame Nebula well—a stellar nursery around 1,400 light years away. It’s less than a million years old and is teeming with brown dwarfs, objects that never quite accumulated enough mass to begin fusing elements in their core. When comparing the James Webb Space Telescope’s (JWST) infrared observations with Hubble's visible light images of the Flame Nebula, the difference is, ahem - astronomical! The infrared wavelengths penetrate the obscuring gas and dust, revealing clusters where young stars and brown dwarfs are taking shape.

US life expectancy hit an all-time high in 2024, CDC says

By MIKE STOBBE, Associated Press NEW YORK — U.S. life expectancy rose to 79 years in 2024 — the highest mark in American history. It’s the result of not only the dissipation of the COVID-19 pandemic, but also waning death rates from all the nation’s top killers, including heart disease, cancer and drug overdoses.

Amid the eucalyptus groves at Natural Bridges State Beach in Santa Cruz, local bug enthusiast Sasha Hernandez squinted through the draping green leaves, searching for flashes of black and orange — the wings of migratory monarch butterflies traveling from west of the Rocky Mountains. Leone Brown, a professor at James Madison University, demonstrates the Project Monarch butterfly tracking app on a phone in Harrisonburg, Va., on Nov. 12, 2025. Scientists used tiny new sensors to follow the insects on journeys that take thousands of miles to their winter colonies in Mexico. butterflies. (Kirsten Luce/The New York Times)  This year, the butterflies’ annual migration will carry a new kind of buzz as smartphones sync with the motions of the monarchs. For the first time in California, citizen scientists like Hernandez can join the effort to track monarch butterflies thanks to Blu+, a new generation of ultra-light tags that communicate using Bluetooth technology. Through the Project Mo...

Number 65 was a male chimpanzee born in 1957 in the French Cameroons in West Africa. After being captured by trappers, he was sent to a rare bird farm in Florida. In 1959, he was sold to the U.S. Air Forc...
