At this point in time, details are limited, but the duo plans to discuss a new space exploration project called “Starshot” at the press conference, taking place at One World Observatory in New York City.

The press conference is going to be live-streamed online starting at 9 a.m. and you can watch the event below.

Right now, little is known about “Starshot,” but the last project the duo worked on was one of the most extensive searches for intelligent life, called Breakthrough Listen.

According to IFL science, people are guessing that “Starshot” is a proposal for a spaceship capable of traveling beyond the Solar System, or possibly an observation program that has capabilities to observe stars besides our sun.

Whatever project Starshot may be, make sure you’re tuned into the livestream this morning.
