Cosmological model of the universe's origin and expansion
Scientists have captured the Sun’s surface at unprecedented resolution with the Daniel K. Inouye Solar Telescope and other instruments and have identified widespread Kelvin–Helmholtz vortices—500–2,000km spirals of magnetised plasma. The team has linked these instabilities to how magnetic energy cascades to smaller scales and feeds flares and coronal mass ejections that produce space weather.
NASA has launched the Nancy Grace Roman Space Telescope aboard a Falcon Heavy, with a field-of-view more than 100 times wider than Hubble. The bus-sized telescope is heading to a point roughly 1 million miles from Earth to study dark energy, dark matter, and thousands of new worlds, while working with Webb and other observatories. It will take months to reach its destination and will begin rapid, wide-area observations.
Researchers at the Niels Bohr Institute have published results showing collisions of oxygen-16 and neon-20 nuclei have produced quark–gluon plasma droplets. The experiments have revealed that particle emission patterns reflect the original nuclear shapes, offering a new probe of nuclear structure and the conditions that existed microseconds after the Big Bang.
