up here, and became almost as bright as the quarter-moon.

The Jewel Box open cluster, NGC4755 (C94), round

ÎCrucis, is one of the loveliest in the sky; its main stars

form a triangle, around a striking red supergiant. It is 7700

light-years away, and the cluster is about 25 light-years

across; it is believed to be no more than a few million years

old, so that by cosmic standards it is a true infant. Close by

it is the dark nebula known as the Coal Sack, which can be

detected with the naked eye as an almost starless region.
