The European Southern Observatory (ESO) will announce an "unprecedented discovery" on Monday:
ESO will hold a press conference on 16 October 2017 at 16:00 CEST, at its Headquarters in Garching, Germany, to present groundbreaking observations of an astronomical phenomenon that has never been witnessed before.
[...] By registering for the conference, journalists agree to honour an embargo, details of which will be provided after registration, and not to publish or discuss any of the material presented before the start of the conference on 16 October 2017 at 16:00 CEST.
LEAK IT!
Update: The announcement will be related to gravitational waves, and may involve a neutron star collision, which would also be visible using optical methods.

Yeah, but... and this is admittedly reading a lot into very little... a planet shouldn't be considered an "astronomical phenomenon that has never been witnessed before", even if it is a new gas giant in our solar backyard.
Meanwhile, Newsweek says "The discovery, which is being kept secret until press conferences are held on October 16, relates to gravitational waves. It involves scientists from the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo Collaboration, along with teams from 70 different observatories across the globe."
