A Somali sengi (Galegeeska revoilii) at the Assamo locality in Djibouti. As is observed in other sengi species, Somali sengis have some variation in pelage colors. These differences seem to correspond to the color variation of substrates between occurrence localities. At the Assamo site, in the extreme southeastern corner of Djibouti, sengi habitats are comprised of rocks with more rusty coloration than elsewhere in the country. Compared to other Djiboutian sites, sengis from Assamo have dorsal pelage hairs with more pronounced reds. Image credit: Steven Heritage.

An artist’s conception of a potential solar companion, which theorists believe was developed in the Sun’s birth cluster and later lost. If proven, the solar companion theory would provide additional credence to theories that the Oort Cloud formed as we see it today, and that Planet Nine was captured rather than formed in place.

This artist’s impression shows ‘Oumuamua, the first interstellar object discovered in our Solar System. Recent observations show that the object is moving faster than predicted while leaving the Solar System. Astronomers assume that venting material from its surface due to solar heating is responsible for this behavior. This outgassing can be seen in this artist’s impression as a subtle cloud being ejected from the side of the object facing the Sun. Image credit: NASA / ESA / Hubble / ESO / M. Kornmesser.
