From member Imran Bader: Deeper in the core of the Rosette nebula, we see several Bok structures. Bok Globules are pockets of dark cosmic dust and gas, usually containing newborn protostars on their way to becoming fully fledged main-sequence stars. 🔭 #astrophotography

The bright gibbous Moon shines over Mars, Pollux, and Castor at nightfall. As evening grows late this scene rotates clockwise, so that by 10 or 11 p.m. Mars shines straight left of the Moon. buff.ly/4gxVDGT . . #astronomy #stargazing #gemini #mars

Mars was at opposition on Thursday, January 16, and member Rich Klein captured this image of the red planet using his 8" Schmidt-Cassegrain telescope. He "took a 5000-frame video, extracted the 600 best frames, aligned them, stacked them, sharpened and denoised them." 🔭 🧪

From Imran Badr: "NGC7814, also known as the Little Sombrero, is an edge-on spiral galaxy in Pegasus. It is about the same size as the Sombrero galaxy (M104) at around 60,000 light-years across, but lies almost twice as far away at around 40 million light years." 🔭

From member Francesco Meschia: "Barnard 343 is one of the dark nebulae in E.E. Barnard’s catalogue. It sits about 2 degrees west of Gamma Cygni and 2 degrees north of the Crescent nebula, and maybe for this reason it doesn’t have many “individual” images on Astrobin." 🔭

That HUGE naked-eye (well, safely-protected-eye) sunspot is still easily visible using eclipse glasses. I just took this pic of it on my phone! And if you want to learn why they form and how to see them, read my new article in Scientific American! www.scientificamerican.com/article/how-... 🔭🧪
