The Battle of the Bagradas River was fought in 240 BC, in present-day north-east Tunisia, between a Carthaginian army led by Hamilcar Barca and a rebel force led by Spendius. Carthage was fighting a coalition of mutinous soldiers and rebellious African cities in the Mercenary War, which had started late the previous year in the wake of the First Punic War. Hamilcar left Carthage and evaded a rebel blockade by crossing the Bagradas River (the modern Medjerda River) at its mouth. Two rebel armies marched towards the Carthaginians. When they came into sight Hamilcar ordered a feigned retreat. The rebels broke ranks to chase the Carthaginians and this impetuous pursuit caused them to fall into disorder. Once the rebels had closed, the Carthaginians turned and charged them. The rebels broke and were routed. The Carthaginians pursued, killing or capturing many of the rebels and taking a bridge over the Bagradas. This victory gave Hamilcar freedom to manoeuvre and the operational initiative.

Arp 273 is a group of interacting galaxies, lying 300 million light years away in the constellation Andromeda and first discovered in 1966. In this photograph from the Hubble Space Telescope, the larger of the spiral galaxies, known as UGC 1810, has a disk that is tidally distorted into a rose-like shape by the gravitational tidal pull of the companion galaxy below it, known as UGC 1813. A swath of blue jewels across the top is the combined light from clusters of intensely bright and hot young blue stars.
