Jellyfish galaxies are spiral galaxies whose gas is pulled into long trails that look like tentacles. The cause is the hot, thin plasma filling galaxy clusters, which pushes against the moving galaxy and strips its gas. Stars form in clumps within those tendrils, under conditions similar to the extreme ones in the disc of a galaxy. JO175, over 650 million light-years away, is a striking example seen by Hubble.

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.
