Look up tonight (March 15) to see the Hyades star cluster light up the Taurus constellation in the night sky.
The Hyades star cluster is the closest star cluster to Earth, located only 150 light-years away. Viewers can spot the star cluster by looking for the tall, Y-shaped constellation Taurus, the bull, which is situated high in the southwest sky on March evenings. The Hyades star cluster lies near the center of the constellation, forming the bull’s face, according to NASA’s March viewing guide.
Another trick to spot the Hyades star cluster is to use the stars of Orion’s belt as a guide to locate the bright orange star Aldebaran. While Aldebaran isn’t actually part of the star cluster, it is located halfway to Hyades and conveniently visible in the foreground, as a part of the V-shaped grouping of stars that comprises the bull’s head.

The Hyades grouping, containing hundreds of stars, is classified as an open star cluster because it’s stars are close together in space, yet loosely bound together by their mutual gravity. While the stars formed together around the same time and from the same cloud of dust and gas, the leftover nebula material was blown away and the stars drifted apart, giving them an open, or diffuse, structure.
“Our own sun formed in a cluster like this,” according to the NASA statement. “Studying these structures helps us understand how stars form and evolve.”
The Pleiades star cluster, also known as the Seven Sisters, is another well-known open cluster located in the constellation Taurus. While the Hyades and the Pleiades star clusters are about the same size, measuring roughly 15 light-years across, the Pleiades cluster is about 3 times farther away. As a result, the Pleiades cluster appears more compact.
The Hyades star cluster is visible to the naked eye tonight in the first few hours after dark and should be easy to spot in the night sky, given its compact and distinctive shape. While skywatchers will be able to see a handful of stars with the unaided eye, viewers looking to see more stars — up to a hundred or more — will need to use binoculars.
