Hubble has captured Arp-Madore 417-391, a pair of galaxies in collision about 670 million light-years away in the southern constellation Eridanus. Gravity has distorted the two galaxies into a colossal ring, with their cores sitting side by side. The target comes from the Arp-Madore catalogue, a list of peculiar galaxies that includes subtly interacting pairs and more dramatic collisions. Hubble's Advanced Camera for Surveys took the image as part of a programme that selects intriguing targets for follow-up by the James Webb Space Telescope and ground-based observatories. Galaxy collisions like this reshape galaxies over billions of years.

Hampi is a UNESCO World Heritage Site in Karnataka, India, with more than 1,600 surviving remains spread over 4,100 hectares. It was the capital of the Vijayanagara Empire from 1336 to 1565. Travellers from Persia and Portugal described it as a prosperous, wealthy and grand city with temples, markets and farms along the Tungabhadra River. By 1500 it was estimated to be the world's second-largest city after Beijing, and probably India's richest at the time. In 1565 a coalition of Muslim sultanates defeated the Vijayanagara Empire, its capital was conquered and destroyed, and the city was left in ruins. Hampi remains a religious centre, with the active Virupaksha Temple at its heart.
