A recent modeling study indicates that asteroid impacts on Earth could have transferred microbial life to Venus over billions of years. Researchers presented findings at the 2026 Lunar and Planetary Science Conference showing that material from Earth might survive the journey and persist briefly in Venus' clouds.

NASA’s Lucy spacecraft has shown that asteroid Donaldjohanson is a bilobate, tumbling object formed 155 million years ago. The flyby also detected traces of ancient liquid water on its surface.

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.

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.
