One-Billion-Year-Old Sand Dunes Spotted on Mars

This oblique color view from the HiRISE instrument onboard NASA’s Mars Reconnaissance Orbiter shows a lithified field of sand dunes within Melas Chasma, Valles Marineris. The large degree of preserved morphology for many of these paleodunes reveals important information regarding the acting wind regime and climate prior to their cementation.

A 5-light-year-long section of the western wall in the Carina Nebula, as observed with adaptive optics on the Gemini South telescope. This mountainous section of the nebula reveals a number of unusual structures including a long series of parallel ridges that could be produced by a magnetic field, a remarkable almost perfectly smooth wave, and fragments that appear to be in the process of being sheared off the cloud by a strong wind. There is also evidence for a jet of material ejected from a newly-formed star. The exquisite detail seen in the image is in part due to a technology known as adaptive optics, which resulted in a ten-fold improvement in the resolution of the research team’s observations.
