When getting your bearings under the stars, itвЂ™s often easiest to spot an asterism and use it as a guide to finding the parentВ constellation.

These are distinctive star patterns that lie within constellations. The items labeled in green on the sky map are known as asterisms. If you are substantially south of these areas, everything on our map will appear higher in yourВ sky. If you are located substantially north of these areas, objects on our map will appear lower in your sky, and some objects near the horizon will not be visible at all. states, southern Canada, central and southern Europe, central Asia, and Japan. The map is accurate for any location at a so-called вЂњmid northernвЂќ latitude. For example, if the map legend says вЂњLooking Southeast,вЂќ you should face southeast when using theВ map. The legend on the map always tells you which direction you should facing, based on midnight viewing. Instead, theВ map focuses on a particular region of the sky each month where something interesting is happening.

Our monthly sky map does not show the entire sky which would be almost impossible.

Sky map produced using Chris MarriottвЂ™s SkymapВ Pro Note: How to Read the SkyВ Map This is all due to EarthвЂ™s rotation, which gives us our days, our nights, and our CosmicВ Clock!Д¬lick hereВ or on map below to enlargeВ ( PDF).

The entire sky moves in the same circular path, with Polaris at itsВ center. Importantly, itвЂ™s not just the Little Dipper that appears to rotate around Polaris. The Sky Map shows the Little DipperвЂ™s position for 4 consecutiveВ hours. This clocklike motion will continue throughout the night.

Wait another hour, and the Little Dipper will have rotated further to positionВ вЂњ2.вЂќ.

Note how the whole constellation has rotated slightly counterclockwise around Polaris and is now in the position labeledВ вЂњ1.вЂќ.

The CosmicВ ClockДЄssuming that an hour has passed, go back to our starting point, the LittleВ Dipper! Below Lyra lies the (nearly) upside-down Northern Cross, whose stars comprise the body of Cygnus, theВ Swan. Look to the right of Draco for the perfect little Parallelogram in the constellation Lyra, the Lyre. Above them both is the head of Draco, the Dragon, whose body winds in an S-shape that curves above the LittleВ Dipper. To the right and near the horizon, look for the Big W shape of Cassiopeia, the Queen, and above her, King Cepheus, in the shape of a childвЂ™s sketch of a house. The bearвЂ™s rump and tail are better known as the Big Dipper, but from a dark location you can make out its entire body, from its legs and paws to the tip of itsВ nose. Greater Bear and BigВ DipperДЇor now, look to left for the constellation Ursa Major, the Greater Bear, which appears to be standing on its nose in this view. WeвЂ™ll get back to the Cosmic ClockВ shortly. With the position of the Little Dipper firmly in mind-perhaps after making a simple sketch-spend the next hour or so enjoying the other celestial sights. If you think of Polaris as the center of a clock face, then the bowl is pointing straight up, like the hour hand of a clock set toВ 12:00. Note how the bowl is located directly above Polaris. YouвЂ™ve just traced the handle and bowl of the Little Dipper, which appears to be standing on end. Look above Polaris to follow a curving line of three dim stars until you reach a small starry rectangle. Give your eyes at least 20 minutes to become adapted to the dark and then look dueВ north to find Polaris, the North Star, less than halfway up the sky.

Be prepared to stay up late and to devote at least 2 full hours to stargazing. the June sky isnвЂ™t fully dark until then. YouвЂ™ll need a nice, dark location away from bright city lights. June is a lovely month, weatherwise, toВ watch the Cosmic Clock in the night sky. Nowhere is this clocklike behavior more evident than in the northern sky. The discovery that nearly all of this apparent motion is caused by Earth rotating on its axis is one of humankindвЂ™s greatest scientific achievements. Like clockwork, every celestial object marches across the sky from east to west and in 24 hours returns to its startingВ point. Less obviously, the stars and constellations also rise and set each day. The Sun and Moon rise in the east and set in the west. Objects in the sky always appear to be moving.
