Roughly 500 light years away in the northern constellation Taurus “The Bull” is this incredible reflection nebula cataloged as Sharpless 2-239, which itself is imbedded in the Taurus Molecular Cloud. What we’re actually looking at here is a group of newborn stars roaring into life; particularly IRS5 or HH154, a newborn binary pair that’s making the biggest splash here in this image. As its jets impact the surrounding star forming hydrogen material warms and illuminates that region.
