On the Move
Wednesday, January 9, 2019: Europe's largest rover field test saw the self-driving SherpaTT rover exploring a Mars-like stretch of land in Morocco. The test was run by a team from Germany's DFKI Robotics Innovation Center. — Sarah Lewin
Tuesday, January 8, 2019: A 3D view of the Orion nebula taken by the flying SOFIA Observatory reveals the complex structures sculpted by the forming stars' powerful stellar wind. This slice, presented at the American Astronomical Society's winter meeting, is reminiscent of a dragon. — Sarah Lewin

So Long, MU69!
Thursday, January 3, 2019: NASA's New Horizons spacecraft captured this image of the Kuiper Belt object MU69, nicknamed "Ultima Thule," shortly after its close flyby on Jan. 1. At the time, New Horizons was about 92,457 miles (148,795 kilometers) away from the bilobed space rock. — Hanneke Weitering
Crescent Moon over NYC
Wednesday, January 2, 2019: A tiny sliver of the waxing crescent moon gleams over New York's Statue of Liberty in this photo taken by Rajat Pal. While the sun illuminates only a small portion of the Earth-facing side of the moon, the rest of the moon's face is faintly illuminated by light reflecting off the Earth's surface, a phenomenon known as Earthshine. Pal captured this photo of the one-day-old moon on Dec. 8, 2018. — Hanneke Weitering
A Star is Born
Tuesday, January 1, 2019: These blue splotches of interstellar dust and gas, lurking 1,000 light-years away in the constellation Perseus, are the "smoking gun" of a newborn star. Known as Herbig-Haro objects, these short-lived clouds form when ionized gas ejected from a newborn star collides with dust and gas in the surrounding nebula. The new star, named SVS 13, is located in the top left of this image from the Hubble Space Telescope. — Hanneke Weitering
