Deep-sky objects shine and the giant planets show off their satellites as the bright light from the Moon disappears from our ...

The Fighting Dragons of Ara, also called the Rim Nebula and cataloged as NGC 6188, comprises dark, star-forming clouds and bright young suns.

Comet 24P/Schaumasse is roughly 10th magnitude, visible using optics or in astrophotos of the sky. Rising shortly before local midnight, Schaumasse is best seen in the early-morning hours — and with ...

East of Gemini, where the bright planet Jupiter has been demanding attention, is the constellation Cancer. Closer to the horizon and to the lower left of the Twins early in the evening as the ...
