During a flyby at 30,000 mph, NASA's Lucy spacecraft captures images of a peanut-shaped asteroid
In its groundbreaking endeavor to investigate the earliest components of the solar system, NASA's Lucy spacecraft has achieved yet another milestone. During a high-speed flyby on April 20, 2025, Lucy passed within 600 miles (about 960 kilometers) of the asteroid Donaldjohanson, capturing the first close-up images of the uniquely shaped celestial body. Lucy successfully captured detailed images of the asteroid that resembles a giant space peanut while traveling at a blistering speed of 30,000 miles per hour (48,000 kilometers per hour) adding a fascinating chapter to the mission's journey. A Surprising Dimension and Form Scientists have been blown away by the early images that Lucy sent back. Donaldjohanson’s shape is long and irregular—its resemblance to a peanut or a lumpy bowling pin is striking. Estimated to be about 5 miles (8 kilometers) long and roughly 2 miles (3.5 kilometers) wide, the asteroid is larger than previously expected. Its two-lobed shape suggests that it could be a "contact binary," which means that it was formed when two smaller asteroids slowly collided and stuck together instead of breaking apart. The asteroid's origin and the violent yet creative processes of our early solar system are being questioned further by this discovery. The spacecraft was able to collect valuable data despite the fact that Lucy only had a brief window to take pictures because of its incredible speed. NASA scientists are currently processing additional images and measurements that will allow them to build a detailed 3D model of Donaldjohanson’s surface and structure in the coming weeks.

Help to reduce high blood pressure lowers dementia risk, study finds
A large-scale study has found that controlling high blood pressure can significantly lower the risk of cognitive decline and dementia in later life, a significant advancement in the fight against dementia. The findings highlight the critical link between cardiovascular health and brain function, suggesting that proactive blood pressure management may be one of the most effective ways to prevent dementia.
