Six planets to align in rare celestial parade

A rare planetary alignment featuring six planets will be visible across the night sky from anywhere on Earth. The event excludes Mars, which is positioned on the opposite side of the sun. Observers can best view it on 28 February and 1 March.

Simulation reveals how Kuiper Belt objects form snowman shapes

24. februar 2026 Rapporteret af AI

Researchers at Michigan State University have developed a computer simulation showing that gravitational collapse can naturally produce double-lobed, snowman-like structures in the outer solar system. These contact binaries make up about 10 percent of planetesimals in the Kuiper Belt beyond Neptune. The findings, published in the Monthly Notices of the Royal Astronomical Society, explain a long-standing puzzle in astronomy.
