NASA's press release added that the discovery involved machine learning that "demonstrates new ways of analyzing Kepler data", but has remained cryptic about what the rest of the conference is going to be about. Kepler has spent the last several years collecting data on thousands of nearby stars in order to find planets orbiting around them.
Very little further information was given about the announcement, which will take place on Thursday.
The space agency called for a press teleconference Thursday at 1 p.m. EST, which will be streamed live on NASA Live.
Kepler's original mission was completed in 2012. "The idea is that if advanced alien civilizations build planet-sized megastructures - solar panels, ring worlds, telescopes, beacons, whatever - Kepler might be able to distinguish them from planets", Wright wrote in a blog post.
In 2014, Kepler was set to another mission which included hunting for more exoplanets.
"The discovery was made by researchers using machine learning from Google".
NASAs's Kepler Space Telescope has been searching for habitable planets since 2009.
But that's not all: the K2 trip has already turned up 515 candidate exoplanets, confirming 178 of those. Kepler-11, imagined here by an artist, is a sun-like star orbited by six planets.
K2 is also "introducing new research opportunities to study young stars, supernovae and other cosmic phenomena".
Experts from NASA and Google will be on hand to explain the latest breakthrough. One of the attendees is Paul Hertz, the director of NASA's Astrophysics division in Washington D.C, as well as Christopher Shallue from Google. Shallue is a senior research software engineer at Google Brain-the tech giant's machine intelligence research team.
