Key Points

  • The Pleiades, or "Seven Sisters," is a bright, bluish star cluster located near the constellation Taurus, visible to the naked eye as a tight, hazy grouping in the night sky.
  • With daylight savings time ending, stargazers will have more evening darkness to view the cluster, which is best seen from October through April in the Northern Hemisphere.
  • Historically, the Pleiades have held cultural and mythological significance—from marking seasonal changes in ancient civilizations to inspiring legends like the Greek story of Atlas and his seven daughters.

The last few months of the year offer some of the most spectacular astronomical events—from supermoons to meteor showers—and with daylight savings time ending this weekend, you'll have even more of a chance to observe the night sky, including The Seven Sisters.

Also known as the Pleiades, this star cluster is one of the most recognizable and brightest celestial features in the night sky. It contains more than 1,000 stars, though only six or seven are visible to the naked eye. Located around the constellation Taurus, the stars shine with a distinct bluish hue—a color that indicates stellar youth.

According to Greek mythology, the Seven Sisters were the daughters of Pleione and her husband, Atlas, who was condemned by Zeus to hold up the sky for eternity. The star cluster also held great significance to many ancient civilizations, often marking the end of the harvest season and the beginning of winter. Even medieval rituals, such as All Hallows' Eve (which evolved into Halloween), occurred when the Pleiades reached its highest point, according to The Old Farmer's Almanac.

To find The Seven Sisters, look for the three stars in the constellation Orion, known as Orion's Belt, and draw a line through these stars to the V-shaped pattern of stars nearby. According to EarthSky.org, this pattern is the face of Taurus the Bull, and the bright star in the middle is the red supergiant star Aldebaran (one of the brightest stars in the sky with a slight orange hue). It can be seen even with moderate light pollution.

From there, look a little farther up and to the right, where you should be able to spot The Seven Sisters star cluster. To the naked eye, it appears as a small, hazy grouping packed tightly together. For a better look, grab a pair of binoculars. The cluster shines in the Northern Hemisphere from October to April, so there is plenty of time to see it.
