New telescopes to help astronomers acquire sharper black hole images

New telescopes to help astronomers acquire sharper black hole images

Science
May 6 (UPI) -- Earlier this year, scientists captured the first up-close image of a black hole. Now, researchers are working on plans to produce even sharper images of the cosmic phenomena. Scientists published their plans for acquiring better black hole images this week in the journal Astronomy and Astrophysics. The plans involve the deployment of two or three coordinated orbital radio telescopes. To showcase the power of their planned constellation of observatories, dubbed the Event Horizon Imager, researchers developed a model to simulate the telescopes' image-making abilities. "There are lots of advantages to using satellites instead of permanent radio telescopes on Earth, as with the Event Horizon Telescope," Freek Roelofs, a PhD candidate at Radboud University in the Netherlands, s...

Omega-3 fatty acids—DHA in particular—contribute to a healthy brain. “The brain’s membranes use these fats to improve cellular structure and brain signaling, which translates into better cognitive function,” says Vasanti Malik, ScD, a research scientist in the Department of Nutrition at the Harvard T.H. Chan School of Public Health. DHA also quells chronic inflammation that can harm brain cells and lead to cognitive decline.Fish is the top source: Eating fatty fish (like salmon, sardines, mackerel, or trout) once a week can help slow cognitive decline and reduce Alzheimer’s risk, research suggests. You can also get omega-3s from walnuts, chia seeds, flaxseed, and hempseed.Let's block ads! (Why?) Food - Health.com
