Regulus near moon on July 7

Regulus is the brightest star in the constellation Leo the Lion.  The moon can help you find it – and maybe the planets Jupiter and Venus – tonight.

Tonight – July 7, 2016 – that bright star shining close to the waxing crescent moon is Regulus, brightest star in the constellation of Leo the Lion. The much brighter starlike object in front of Leo isn’t a star, but the dazzling planet Jupiter.

You’ll see the moon closer to Jupiter tomorrow night, on July 8.

An imaginary line drawn between the pointer stars in the Big Dipper - the two outer stars in the Dipper's bowl - points in one direction toward Polaris, the North Star, and in the opposite direction toward Leo.

If you look carefully, you might make out a backwards question mark pattern in the stars around Regulus. This asterism (or recognizable pattern within a constellation) is called The Sickle in Leo.

The moon moves eastward in front of the constellations of the Zodiac from night to night. Once it has moved onward away from Leo, you can always use the bowl of the Big Dipper to find your way to Regulus.

Regulus is considered to be one of the four Royal Stars of ancient Persia. These Royal Stars mark the four quadrants of the heavens. They are Regulus, Antares, Fomalhaut, and Aldebaran.

Four to five thousand years ago, the Royal Stars defined the approximate positions of equinoxes and solstices in the sky. Regulus reigned as the summer solstice star, Antares as the autumn equinox star, Fomalhaut as the winter solstice star, and Aldebaran as the spring equinox star. Regulus is often portrayed as the most significant Royal Star, possibly because it symbolized the height and glory of the summer solstice sun. Although the Royal Stars as seasonal signposts change over the long coarse of time, they still mark the four quadrants of the heavens.

Regulus is the only bright star to reside almost squarely on the ecliptic – the Earth’s orbital plane projected onto the sphere of stars. Regulus coincided with the summer solstice point some 4,300 years ago. In our time, the sun has its annual conjunction with Regulus on or near August 23, or about two months after the summer solstice – or alternatively, one month before the autumn equinox. Regulus will mark the autumn equinox point some 2,100 years into the future.

What is the ecliptic?

Four years ago, in 2012, Regulus reached a place on the Zodiac where it was precisely 150o east of the March equinox point (and 30o west of the September equinox point). Before that juncture, Regulus and the March equinox point were a little less than 150o apart, and Regulus and the September equinox point were a little more than 30o apart. For some astrologers, this instant at which Regulus was precisely 30o west of the September equinox point marked the end of the Age of Pisces and the beginning of the Age of Aquarius.

Whether you enjoy the arcane speculation on the Royal Star Regulus and the Age of Aquarius – or not – that star near tonight’s moon has visually given definition to the ecliptic and the Zodiac since time immemorial!

When does the Age of Aquarius begin?

Although we show the moon at the same time daily, remember that the moon sets later after sunset with each passing day.

The moon has been moving upward, away from the sunset, for the past few evenings. Notice that its lighted portion points to Venus.

Bottom line: Regulus is the brightest star in the constellation Leo the Lion.  The moon can help you find it – and maybe the planets Jupiter and Venus – on the night of July 7, 2016.
