Strange objects near neighboring galaxies brighten, then dim
A pair of unknown objects near neighboring galaxies appear to produce extremely bright X-ray flares, then dim after about an hour. Astronomers aren’t sure what these objects are, noting that nothing like them has ever been spotted in the Milky Way.
Landslides appear to have occurred on Charon
Evidence of landslides has been discovered on Charon, Pluto’s largest moon. Researchers aren’t sure what caused the landslides, which have never been detected on any Kuiper Belt object before, but potential triggers include subsurface tectonic movement or meteorite impacts.
Neanderthal DNA linked to immune system differences
