Hints of a volcanically active exomoon
A rocky extrasolar moon (exomoon) with bubbling lava may orbit a planet 550 light-years away from us. This is suggested by an international team of researchers led by the University of Bern on the basis of theoretical predictions matching observations. The 'exo-Io' would appear to be an extreme version of Jupiter's moon Io.
Might just be bubbling imagination, but then again, it might be true.
Artist's composition of a volcanic exo-Io undergoing extreme mass loss. The hidden exomoon is enshrouded in an irradiated gas cloud shining in bright orange-yellow, as would be seen with a sodium filter. Patches of sodium clouds are seen to trail the lunar orbit, possibly driven by the gas giant's magnetosphere.

Deep-sea sediments reveal solar system chaos: An advance in dating geologic archives
In a study published in the journal Science, Richard Zeebe from the University of Hawai'i at Manoa and Lucas Lourens from Utrecht University used geologic records from deep-sea drill cores to extend the astronomical time scale beyond 50 million years, by about 8 million years. Using their new chronology, they provide a new age for the Paleocene-Eocene boundary (56.01 Ma) with a small margin of error (0.1%).
