Can Strongly Lensed Type Ia Supernovae Resolve One of Cosmology’s Biggest Controversies?

Image - This composite of two astrophysics simulations shows a Type Ia supernova (purple disc) expanding over different microlensing magnification patterns (colored fields). Because individual stars in the lensing galaxy can significantly change the brightness of a lensed event regions of the supernova can experience varying amounts of brightening and dimming, which scientists believed would be a problem for cosmologists measuring time delays. Using detailed computer simulations at NERSC, astrophysicists showed that this would have a small effect on time-delay cosmology. (Credit: Danny Goldstein/UC Berkeley)

X-Rays Reveal ‘Handedness’ in Swirling Electric Vortices

Image - Just as people can be left-handed or right-handed, scientists have observed chirality or "handedness" in swirling electric vortices in a layered material. (Credit: Pixabay)
