Stellar stream of galaxy NGC 5907 has a morphology different than previously thought

Using Dragonfly Telephoto Array, astronomers have revisited the spiral galaxy NGC 5907 and provided more insights into the morphology of its stellar stream. The new observations indicate that this feature has a qualitatively different morphology than when it was observed about a decade ago. The new findings are reported in a paper published June 26 on arXiv.org.
