Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary massive star. Observations, carried out using the Resolve instrument aboard the Japanese XRISM telescope, now allow us to […]

Stellar streams are trails of stars that astronomers can study to solve mysteries about the history of our Milky Way galaxy and, potentially, the dark matter that helps shape the cosmos despite eluding direct observation. These streams have largely been left behind by small dwarf galaxies and globular clusters, which have since petered out of […]

Jupiter’s lightning has long been of interest to planetary scientists, as it marks stormy spots where researchers can look to learn more about convection in Jupiter’s atmosphere. Observing lightning from a distance can be tricky, so scientists have focused on the bolts that are easiest to study: strong flashes that strike at night. As a […]

Nearly a millennium ago, astronomers witnessed a brilliant new star blazing in the sky—a supernova so bright it was visible in daylight for weeks. Today, its expanding remnant, the Crab Nebula, continues to evolve 6,500 light-years away. First linked to historical records by Edwin Hubble, the nebula has since been studied in exquisite detail by […]
