A first guide to the northern night sky

Choose a place where you are allowed to be after dark, preferably with an open view towards the part of the sky you want to see. Scout the route in daylight, check the weather, dress for the conditions and stay clear of roads and other hazards. NASA's site-finding guide covers access and safety as well as the effect of nearby light.

Use the Tonight check for forecast and Moon context and the map to explore an area. The map's 2022 satellite-light layer is a view of lights seen from space, not a local darkness measurement or proof of access. Clouds, nearby lights, the Moon and obstructions can all change what you see.

Look for the Big Dipper, a seven-star pattern that forms part of Ursa Major. Find the two stars on the outer edge of its bowl, away from the handle. Extend a line from the lower one through the upper one to reach Polaris, the North Star. NASA's illustrated explanation shows the pointer stars and Polaris at the end of the Little Dipper's handle.

Polaris is close to the north celestial pole, so it appears to move only a small amount as the sky turns. It marks approximately true north, not magnetic north, and it is not the brightest star in the sky. Use it for rough orientation, not as your only navigation method.

The stars appear to circle the celestial pole through the night. Some stay above the horizon throughout that circle; astronomers call them circumpolar. Which stars do so depends on your latitude. NASA's guide to circumpolar constellations explains the idea using northern constellations.

The Big Dipper will not always be easy to see: it can be low, hidden by buildings or terrain, or partly below the horizon depending on location and time. Polaris also appears lower as you travel towards the equator. Set a current sky chart to your observing location and time, and give yourself a clear northern horizon if possible.

Cassiopeia's five prominent stars form a W or M shape, depending on its orientation. Like the Dipper, it appears to turn around the northern sky, so compare the pattern with a chart rather than expecting it to sit upright. NASA's circumpolar guide includes a chart of Cassiopeia and nearby stars.

If the pattern is hidden or hard to distinguish, wait for a clearer view or try another time. Binoculars can show more stars in the area, but identify the wider shape with your eyes first.

Orion is a useful seasonal target when it is above your horizon. Look for three bright stars in a short line: Orion's Belt. The reddish star Betelgeuse and blue-white Rigel help frame the larger pattern. NASA's Orion overview identifies these stars and the Orion Nebula in the sword below the belt.

In very clear, dark conditions the nebula can be visible to unaided eyes as a faint patch; binoculars may reveal more. It is not guaranteed from every location or under bright skies. Orion is also visible from many places in the Southern Hemisphere, with a different orientation.

Check that your chart has the correct date, time and location. Face the direction it shows, then look for the brightest stars before joining the pattern. If cloud, moonlight or local lights hide fainter stars, start with the Moon or return another night. Reduce screen brightness and let your eyes readjust after using a phone.

No telescope is needed for a first session. If you use binoculars, support your arms and never point them at the Sun. For a simple checklist, see Your first night stargazing.
