Watching a Rare Giant Star Die

A team of astronomers from the University of Arizona created a detailed, 3-D image of a dying hypergiant star. They traced the distribution, directions, and velocities of various molecules surrounding a red hypergiant star known as VY Canis…

Comet Roasts to Death

For the first time, astronomers have captured images of a periodic rocky near-Sun comet breaking apart, a common fate for heavenly bodies with destabilized orbits. Because they pass so close to the Sun, they are challenging to study, and…

Engineers Develop LEGO-like AI Chip

Instead of tossing out devices when there's a new model, we could upgrade them with the latest sensors and processors that snap onto a device's internal chip — like LEGO bricks. Such reconfigurable chips could keep devices up to date and…

Paving the Way for Stronger Alloys

In alloy research that is breaking new ground, University of Birmingham scientists described how microscopic crystals grow and change shape in molten metals, paving the way for improving the tensile strength of alloys used in casting and…
