Inside Sky & Telescope's January 2020 Issue
Sabrina Garvin, Sky & Telescope
In January’s issue of Sky & Telescope, join scientists in exploring what might be living beneath the surface of Mars. After discovering microbes on the ocean floor and deep in Earth’s crust, scientists hope to find water and microorganisms hidden in the Martian crust. NASA’s Spitzer Space Telescope has documented exoplanets crossing in front of their stars and detected galaxies seen as they were over 13 billion years ago. Now, relive the scientific discoveries of the Spitzer, as it prepares to send Earth its final observations. Next, take a step even further back in time and watch as astronomer Father William Rigge saves an innocent man from a murder conviction using a photograph and the Sun. Join Fred Schaaf as he uses song lyrics from Cat Stevens’ Silent Sunlight to describe the January night sky. If you’re up for a challenge, join us in hunting down the Kordylewski Clouds. First found by Kazimierz Kordylewski, these clouds are the most challenging observing target in the solar system. Even professional astronomers and space probes have failed to detect them. Jerry Oltion will take you on a journey through the winter stars, and Sue French is taking another look at Auriga the Charioteer this month. January has plenty of meteor showers planned. Watch out for two bright asteroids, 5 Astraea and 511 Davida.
