To gaze at the stars is human. To be able to see them in 3D detail is very nearly divine.
Divine vision is what the James Webb Space Telescope has granted Earthbound scientists in a new near-infrared, detailed image of Cassiopeia A (Cas A), a stellar remnant—the clouds of gas, dust and other material left behind when a star dies. Danny Milisavljevic, assistant professor of physics and astronomy in Purdue University’s College of Science, studies supernova remnants and leads a year one research team on the JWST examining Cas A.

Like batteries, fuel cells produce energy through an electrochemical process. Unlike batteries, they don’t run down or require recharging. However, the potential advantages of fuel cells are offset by challenges that include cost, performance and durability.

Bosons, one of the two fundamental classes of particles, have been the focus of countless physics studies. When bosonic particles are transitioning into an already occupied final quantum state, the rate of this transition is enhanced by its so-called “occupation number,” an effect known as bosonic stimulation. The appearance of bosonic stimulation in light scattering processes was first predicted over three decades ago, yet directly observing it in experimental settings has so far proved challenging.
