Unique, twisting dust lanes are prominent in this Hubble image—an edge-on view of lenticular galaxy NGC 4753. That dust likely was pulled in during a merger with a dwarf galaxy more than 1 billion years ago. Credit: NASA, ESA, and L. Kelsey. 🔭 🧪

This region, called G35.2-0.7N, is a hotbed of high-mass star formation. Much of this nebula is dark and dusty. However, massive jets, like the one that is launching toward us, pierce through the darkness, giving us a view inside. Credit: ESA/Hubble & NASA, R. Fedriani, J. Tan. 🔭 🧪
