This time of year is a great time for #southpole pictures, including this one from Anjali, showing the deep blue skies right now! You can really see the ice and snow buildup on and around the building by mid-winter. #Antarctica #NSF #DOEScience

Check out this view ➡️ 🤩 Cerro Pachón definitely understood the assignment. This panoramic sunset view captures NSF–DOE Rubin Observatory atop its summit site above the Chilean landscape. 🔭🧪 The night skies here are spectacular, but the mountains put on quite a show before the stars come out too 🌟

Flocculent spirals, like NGC 2090, seen in this #NASAWebb image, are one of the more common types of spiral galaxies. They have patchy arms that seemingly blend together and disconnect in spots. Credit: ESA/Webb, NASA & CSA, A. Leroy. 🔭 🧪
