In a few hours, NASA is scheduled to hold a press briefing on a new discovery made by the Chandra X-Ray telescope. According to the press release, it will concern a celestial object "in our Galaxy" that astronomers have been hunting for more than 50 years.
I'm just wondering if it might be Planet X?
It seems like a long shot, especially since Planet X is a solar system object, not "in our galaxy," but we'll see.
UPDATE: They found a young Supernova.
