One of the last images of Comet 67P/Churyumov-Gerasimenko that was taken by the European Space Agency’s Rosetta mission. This shot was taken at 0818 UTC 9/30/16 from an altitude of 5.7 km above the comet’s surface. Rosetta’s mission ended when the spacecraft was sent crashing into the comet’s surface. (ESA)

Up up and away! The 3rd of six Jet Propulsion Laboratory Remote payload flights was launched on 9/27/16, from NASA’s Scientific Balloon Launch Site at Fort Sumner, New Mexico. JPL’s Remote mission is an upper atmosphere research experiment that will help better understand stratospheric chemistry and the stability of the ozone layer. (NASA/JPL)

Here’s another photo, taken in September 2016, of another odd sea creature found by researchers during a recent expedition to study the biodiversity and mechanisms of an unusually rich deep-sea ecosystem off the coast of Hawaii. In this photo provided by the National Oceanic and Atmospheric Administration, is a Commerson's frogfish. (NOAA via AP)

This animation released by on 9/15/16 by NASA shows the slow migration of building-size fragments from Comet 332P/Ikeya-Murakami over a three-day period in January 2016. The animation was made from a sequence of Hubble Space Telescope images. The fragment broke off of the comet’s main nucleus in late 2015 its orbit brought it close to the sun (NASA, ESA, D. Jewitt (UCLA))
