NGC 6822, also called Barnard's galaxy, is a barred irregular dwarf galaxy about 1.6 million light-years away in Sagittarius. This image combines older optical data from the La Silla Observatory with new observations from the ALMA radio telescope in Chile. ALMA picked up carbon monoxide, a molecule that traces the dense molecular hydrogen gas where stars form. In the Milky Way, stars form in the dense cores of giant gas clouds, and this galaxy turns out to have similar small, dense cores. That was hard to see before in other galaxies, especially low-mass, low-metallicity ones. The finding suggests that star formation works in the same way in small galaxies as in our own.

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.
