On the 26th of September, 2022, at 23:14 UT, the APL/NASA Double Asteroid Redirection Test (DART) spacecraft impacted successfully on the secondary of the NEA binary asteroid (65803) Didymos, after a 10 months travel. [1] The 589 kg spacecraft impacted Dimorphos at 6.14 km/s, and images of the system were taken by the DRACO camera onboard DART

Context. Realistic three-dimensional time-dependent simulations of stellar near-surface convection employ the opacity binning method for the efficient and accurate computation of the radiative energy exchange. The method provides several orders of magnitude of speedup, but its implementation includes a number of free parameters. Aims: Our aim is to

We present the results of an analysis of the precise spatial orientation of colonial Christian churches located in the Canary Island of Fuerteventura (Spain). Our sample consists of 48 churches, most built during the period between the Castilian conquest led by the Norman Jean de Béthencourt in the early fifteenth century and the end of the

We study the evolutionary path of the Fornax Cluster galaxy NGC 1436, which is known to be currently transitioning from a spiral into a lenticular morphology. This galaxy hosts an inner star-forming disc and an outer quiescent disc, and we analyse data from the MeerKAT Fornax Survey, ALMA, and the Fornax 3D survey to study the interstellar medium

We present observations from X-ray to mid-infrared wavelengths of the most energetic non-quasar transient ever observed, AT2021lwx. Our data show a single optical brightening by a factor >100 to a luminosity of 7 × 10 45 erg s -1 and a total radiated energy of 1.5 × 10 53 erg, both greater than any known optical transient. The decline is smooth and

M31N 2008-12a, located in the Andromeda galaxy (M31), is the best studied recurrent nova. It presents periodic outbursts with about one year between eruptions. However, the annual eruption date varies from year to year. In order to discover the annual eruption and facilitate the multi-wavelength follow-up, a monitoring campaign with nightly cadence
