Stars & Constellations

It depends on the month and your hemisphere. This page lists this month's best constellations for mid-northern latitudes, plus tonight's moon brightness and Milky Way visibility. Search your city to see your local dark-sky window.

A very bright 'star' that doesn't twinkle is usually a planet — most often Venus, Jupiter, or Mars. The brightest true star is Sirius, visible in winter and spring evenings low in the south-east to south.

Start after astronomical twilight ends, roughly 90 minutes after sunset, when the sky is fully dark. The darkest skies come when the Moon is down or near new moon.

You need a dark site away from city lights, a clear sky, and little or no moonlight. The core of the Milky Way is best from about March to October in the Northern Hemisphere. Our Milky Way card above shows this month's visibility.

As Earth orbits the Sun, the direction we face into space at night gradually shifts over the year, bringing different constellations into view and rotating others out — a real, predictable cycle rather than the stars themselves moving.

The optimal observation window opens during maximum astronomical dark hours, when moon illumination is low and local cloud cover stays under about 20% for a genuinely clear sky.

Baseline tracking can be done with the naked eye. For fainter, low-contrast targets, a steady tripod-mounted pair of wide-field binoculars or a small telescope makes a real difference.

Search your specific city or coordinates above — visibility depends on your exact latitude and local horizon, not just your general region.
