Which constellation is known for its brightest star named Antares?

Antares is widely recognized as the brightest star in the constellation Scorpius. This star is often referred to as the "heart" of the scorpion in mythological terms, and it is distinctly bright and reddish in color, making it a prominent feature of the summer sky in the northern hemisphere. Scorpius is easily identifiable due to its curved shape, resembling a scorpion, and Antares serves as a key marker within this shape.

In contrast, the other constellations listed do not feature Antares. Taurus is known for the Pleiades star cluster and the bright star Aldebaran, while Ursa Major is noted for including the Big Dipper and does not include any stars named Antares. Virgo's brightest star is Spica, which again highlights that Antares specifically belongs to Scorpius, making it clear why this is the correct choice.
