Astronomy Tuesday


This vaguely creepy looking blob -- like an evil snowman come to life -- is Ultima Thule, the Kuiper Belt object 6.5 billion kilometers from the Sun encountered by the New Horizons spacecraft last week. Technically Ultima is the larger of the two blobs and Thule is the smaller; they probably teamed up as the result of a collision shortly after the formation of the Solar System and have been held together by gravity ever since.
