The Night Sky Tonight

Planets, meteors, the Moon, over your spot
Four things change night to night: which planets are up, whether a shower is running, where the Moon is, and how dark your sky stays. Here is how to read each, then the live map that does it for your location.

You do not need gear to read the night sky. With your eyes alone you can name the bright planets, catch meteors, and track the Moon through its phases. What is actually up tonight comes down to the date, the hour and where you stand, and once you know what to look for, the whole dome stops being random points and starts being a map you can read. Start with the four things that change, then open the live view for your own spot.

The planets

Five planets shine bright enough to see without a telescope: Mercury, Venus, Mars, Jupiter and Saturn. The quickest way to spot one is that a planet holds a steady light while the stars around it twinkle. Venus is the brightest, low in the west after sunset or the east before dawn. Jupiter is a steady cream colored beacon. Mars shows plainly red. Saturn is a calmer gold. They all ride the same arc across the sky, the ecliptic, so trace the path the Sun took and you are sweeping the band they live in.

The meteors

On any dark night you can catch a few meteors an hour, stray dust the Earth sweeps up. A few times a year the planet crosses the debris trail of a comet and the rate climbs to dozens, which is a meteor shower. The big dependable ones are the Perseids in August and the Geminids in December, with Quadrantids, Lyrids, Eta Aquariids, Orionids, Leonids and Ursids filling out the year. All of them run best in the hours after midnight.

Planets hold still, stars twinkle, meteors streak and vanish, the Moon moves and changes shape.
Four signatures. Learn them once and you can read any clear night over any backyard.

The Moon

The Moon runs a full cycle of phases every twenty nine and a half days, from new to full and back. It matters for more than itself, because a bright Moon washes out faint meteors and dim stars. The darkest skies, and the best nights for shooting stars, fall around the new Moon when it is out of the way. Knowing tonight's phase tells you how much the Moon will drown out everything else.

Your dark, and your horizon

The single biggest factor in what you see is how dark your sky is. City glow erases all but the Moon, the planets and a few bright stars. Twenty minutes toward darker ground, and the sky fills back in. Your horizon matters too, since a planet or a radiant below the skyline simply is not visible yet. The live map accounts for both by reading the sky from your exact location.

The live sky over your spot

The generic answer changes the moment you move or the clock turns. The live instrument takes your location and the current time and lays out the planets, the Moon and the active sky as they stand right now, so you can face the right way and know what you are looking at.

Sky Intel

The nights worth stepping outside, sent to you.

Most clear nights are quiet. A handful a year are not: a meteor peak with the Moon down, two planets drawing into a conjunction, the Moon sitting right beside Jupiter. Those pass in a night or two. Magna Earth watches the sky over your coordinates and tells you which nights are the ones to walk out to a dark corner for.
