#PencilNebula | This shock wave plows through space at over 500,000 kilometers per hour. Moving toward to bottom of this beautifully detailed color composite, the thin, braided filaments are actually long ripples in a sheet of glowing gas seen almost edge on. About 5 light-years long and a mere 800 light-years away, the Pencil Nebula is only a small part of the #VelaSupernovaRemnant.
An image of the Cartwheel Galaxy taken with the NASA/ESA Hubble Space Telescope has been reprocessed using the latest techniques to mark the closure of the Space Telescope European Coordination Facility (ST-ECF), based near Munich in Germany, and to celebrate its achievements in supporting Hubble science in Europe over the past 26 years.
NGC 602 is a young, bright open cluster of stars located in the SMC, a satellite galaxy to the Milky Way. Radiation & shock waves from the stars have pushed away much of the lighter surrounding gas & dust that compose the nebula known as N90, & this in turn has triggered new star formation in the ridges (or "elephant trunks") of the nebula
