After recently possible discovery of first exomoon, there is next interesting possible discovery.


Kepler Space Telescope discovered first possible evidence for exocomets transiting their stars

Transits of extra-solar planets are pretty routine these days, but planets are not the only bodies expected to be orbiting nearby stars. How about exo-comets? Unlike planets, comets are fuzzy and changeable, so exocomet transits would vary in shape and depth. A team led by Saul Rappaport have now searched the entire archive of Kepler lightcurves looking for dips that could be exocomet transits.

There is one in the data for the star KIC 11084727:


The authors reproduce such dips (red line) with a model of a comet about the size of Halley’s comet and having a tail made of dust, hence giving an asymmetric dip.
