The crow or raven, perched on the back of Hydra beside a cup it can never drink from. In Greek myth it was punished by Apollo for lying.
From New York on October 13, 2026, the centre of Corvus rises at 6:58 AM, is highest at 11:46 AM (29° above the horizon in the S) and sets at 4:39 PM.

Name and history
Corvus and its neighbours share a moral tale that goes back at least to Eratosthenes in the third century BC. As Ovid tells it, Apollo sent his crow to fetch water from a spring with a bowl. On the way it found a fig tree with unripe fruit and waited days for the figs to ripen, then feasted on them. To excuse its delay it brought back a water snake and claimed the snake had blocked the spring. Apollo saw through the lie and placed the crow, the cup and the snake in the sky, with the cup just out of the thirsty bird’s reach.
In another tale, told by Ovid, the crow was once white, until it brought Apollo the news that his lover Coronis had been unfaithful and he turned its feathers black. Gienah, its brightest star, comes from an Arabic word for the wing. In Chinese astronomy four of its stars formed Zhen, the chariot, which also named the last of the lunar mansions.

Deep-sky objects
Galaxies, clusters and nebulae brighter than magnitude 9, from the OpenNGC catalogue. Most need binoculars or a telescope and a dark sky.

How to use this page
Choose your place and a night at the top. The answer and the 3D view show where the constellation is, when it is highest and whether it rises at all from where you are. The chart shows its stars and lines, and the tables list its brightest stars and the deep-sky objects inside it.
Frequently asked questions
When is a constellation best seen?
When it is highest in a dark sky, which the page gives for the night you pick. Each constellation is best placed in a particular season, because the stars rise about four minutes earlier every night.
Why can I not see a constellation from my place?
Constellations far south of the celestial equator never rise from northern places, and those far north never rise from southern ones. The page says when this is the case.
What are the constellation boundaries?
The International Astronomical Union divides the sky into 88 areas with official boundaries. The stick figures are only a drawing aid, the boundaries say which constellation a point in the sky belongs to.
