Astronomy Magazine Highlights Predawn Planetary Alignment on April 20
On April 20, 2026, a rare celestial event will occur as Mercury, Mars, and Saturn align in the early morning sky. This alignment will be visible approximately 30 minutes before sunrise, provided there is a clear eastern horizon. Mercury, the brightest of the trio, will be visible at magnitude -0.2, followed by Saturn at magnitude 0.9, and Mars at magnitude 1.2. The planets will be positioned within a 2-degree-wide area, making them a challenging but rewarding sight for early risers. Observers are advised to use binoculars or a small telescope to enhance visibility, as the planets will rise shortly before the sun.
