In 1604, astronomers first caught sight of Kepler's Supernova Remnant, a massive explosion some 17,000 light-years away. Twenty-five years of observations from the Chandra X-ray Observatory went into making this timelapse, which shows the supernova remnant's material pushing into the surrounding gas and dust.

In December 2024, Parker Solar Probe made its closest pass yet to our Sun. In doing so, it captured the detailed images seen here, where three coronal mass ejections -- giant releases of plasma, twisted by magnetic fields -- collide in the Sun's corona.  (Image credit: NASA/Johns Hopkins APL/Naval Research Lab; video credit: NASA Goddard; via Gizmodo) Read the full article

Icebergs have long served as a metaphor for not knowing what's going on beneath the surface. Studies like today's are a reminder of why that is.  (Image and research credit: M. Berhanu et al.; via APS)

A sudden breeze can pluck droplets hanging from a stem. Here, researchers recreate that phenomenon in the laboratory. With a close-up view and high-speed images, we can enjoy every detail of the detachment and break-up. (Video and image credit: D. Maity et al.)

In mechanical systems, gears and pulleys transmit rotation from one location to another. Here, researchers explore a fluid dynamical version of such systems. (Image credit: J. Smith et al.)
