I saw an even fainter extension of the Great Sagittarius Starcloud stretching as far west as Delta Scorpii, the star that has been brightening so dramatically in the last few years, and as far east as Corona Australis. To the north, this enormous central bulge begins in Ophiuchus and tapers off south of the starcloud, to the Eta Carinae Nebula.
Returning south, we find near the zenith the small grouping of Corona Australis, the Southern Crown.

Jeremy Drake (Harvard-Smithsonian Center for Astrophysics) and his colleagues focused on the nearby neutron star RX J1856-3754, located 400 light-years away in Corona Australis. They observed it at both X-ray and visible wavelengths using Chandra and the Hubble Space Telescope.
Below the Teapot there is even a lemon wedge, the brightest stars of Corona Australis. Completing the picture, the hazy band of the summer Milky Way stretches above Sagittarius like steam rising from our celestial Teapot's spout.
In April an X-ray source flared up for several weeks at the border of Sagittarius and Corona Australis. Rudy Wijnands and Michiel van der Klis (University of Amsterdam) examined it with the Rossi X-ray Timing Explorer satellite and found that its X-ray output pulses 401 times per second.
We quickly settled on not one, but two celestial figures: Corona Borealis and Corona Australis. The first we dubbed Crustum Boreale, and the other Crustum Australe.
This seldom-seen gem is the fain test of a trio of three small nebulae in the northwest corner of Corona Australis. It resembles the better-known Hubble's Variable Nebula C46 (NGC 2261) far to the north in Monoceros.
