What are the main stars of Taurus and Scorpio? I mean, mainly, not all.

Scorpio: Alpha star of Scorpio (Antares), 9 bright stars.

Because this constellation is located near the center of the Milky Way, it contains a large number of deep space objects, such as open cluster M6 (butterfly cluster), M7 (Ptolemy cluster), globular cluster M4 and M80, and the famous open cluster NGC 623 1.

Taurus: α τ (Wu), three bright stars.

The most famous celestial body in Taurus is "two clusters plus a nebula". Connecting Orion γ star and Cebu star, extending about twice the distance to the northwest, there is a famous open cluster-Pleiades cluster. People with good eyesight can see seven bright stars in this cluster, so it was also called "Seven Star Cluster" in ancient China.
