Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and space-craft-borne instruments of the electromagnetic radiation and high-energy particles emitted by celestial bodies.
The astronomy and quantum information science communities met together in a one-day workshop to share experiences and ideas on how to reach the next level — the quantum level — of astronomical interferometry.
A phenomenon that affects the magnetic fields of rotating bodies could be involved in recurring changes in the Sun’s behaviour, which are related to a periodic flipping of its field. The proposal is a fresh take on this strange effect.
Alkylsulfonic acids represent an alternative source of sulfur for the origins of life. Here the authors demonstrate, via laboratory simulation experiments, the formation of these compounds in interstellar analog ices with implications for their incorporation into asteroids such as Ryugu.
The accretion disk from a star tidally disrupted by a supermassive black hole undergoes Lense–Thirring precession with strong, quasi-periodic X-ray flux and temperature modulations.
Simple analytic estimates and detailed numerical calculations show that the solar dynamo begins near the surface, rather than at the much-deeper tachocline.

Simulated lunar exploration in an Arizona volcanic field this month helped astronauts to prepare for doing geology in harsh conditions at the lunar south pole. Nature joined mission control.
