Physicists model the supernovae that result from pulsating supergiants like Betelgeuse

Unlike most stars, Betelgeuse is large enough and close enough for scientists to resolve with instruments like the ALMA telescope. Credit: ALMA (ESO/NAOJ/NRAO) Betelgeuse has been the center of significant media attention lately. The red ....

Examining ice giants with NASA’s Webb telescope

This Voyager 2 image of Neptune shows a cold and dark wind-whipped world. In 1989, NASA's Voyager 2 became the first and only spacecraft to observe the planet Neptune, passing about 3,000 miles above the ....

Innovative switching mechanism improves ultrafast control of microlasers

Ultrafast control of the quasi-BIC microlasers. (A) Schematic of two-beam pumping experiments. Two beams are spatially detuned with a distance d < 2R, being shifted temporally with a delay time τ. The insets show the ....
