NASA’s Lucy Begins Camera Tests Ahead of 2027 Trojan Flybys – NASA Science

NASA’s Lucy Begins Camera Tests Ahead of 2027 Trojan Flybys – NASA Science

Preparing for the NASA Lucy spacecraft’s first Trojan asteroid encounters, mission scientists have begun instructing the spacecraft to turn its cameras toward its future targets. From hundreds of millions of miles away, the asteroids appear as pinpricks of light. Yet, these early observations will help the team select the best camera settings for Lucy’s upcoming

APOD: 2026 August 6 – New Sharpest Image of the Sun Uncovers Instability – NASA Science

Explanation: What does the new sharpest image of our Sun show? Instability. To be clear, a certain kind of interactive process called the Kelvin-Helmholtz instability (KHI). This instability can create waves and swirls when two streams flow past each other — in this case variable streams of solar magnetic plasma. Long hypothesized to occur on the Sun’s surface, KHI streaks and swirls
