Cosmological model of the universe’s origin and evolution
Astronomers have detected helium escaping from LHS 1140b, a rocky 'super-Earth' 48 light-years away that orbits in its star's habitable zone. The finding has confirmed an atmosphere around a habitable-zone rocky exoplanet for the first time and has been published in Science; teams used ground-based infrared spectroscopy and modelling.
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.
The LUX‑ZEPLIN (LZ) collaboration has reported a single unexplained particle interaction recorded on 16 June 2023 at the Sanford Underground Research Facility that matches the expected signature of a WIMP. The team has presented the finding at a conference, uploaded a paper and asked the wider physics community for scrutiny; the result falls short of the 5‑sigma discovery threshold.
