(CNN) -- A Chinese satellite looking into the mysterious disappearance of Malaysia Airlines Flight 370 "observed a suspected crash area at sea," a Chinese government agency said -- a potentially pivotal lead into what has been a frustrating search for the Boeing 777.
China's State Administration for Science, Technology and Industry for National Defense announced the discovery, including images of what it said were "three suspected floating objects and their sizes."
The images in the Strait of Malacca were captured on March 9 -- which was the day after the plane went missing -- but weren't released until Wednesday.
This isn't the first time that authorities have announced they were looking into objects or oil slicks that might be tied to plane, which went missing last Saturday.
Earlier Wednesday, officials announced they had once again expanded the search area. It now covers nearly 27,000 square nautical miles, more than double the size of the area being searched just a day before.
