A handful of planets in the solar system are expected to line up in the night sky for a few days in January 2025. Here's when to look up at the stars.

Skywatchers: A six-planet alignment peaks this week as Mars, Jupiter, Uranus, Neptune, Venus, and Saturn come together for view shortly after sunset in the sky.

Mars will be making its closest approach to Earth in two years, and thus, the mighty red planet, named for the god of war himself, will appear brighter, bigger, and bolder in the night sky. This Martian exclamation point will further amplify the experience of the alignment.
