Star-gazing boffins trying to figure out how many stars there are in the sky have lost count.
But according to an astronomy insider, they've issued a new estimate to cover up their gaffe.
The space experts at Yale University last week said there could be as many as three times more stars than was previously believed.
They said there could be as many as three septillion stars in the universe - that's a three followed by 24 zeroes.
But a former colleague of the Yale team says this is just a guess.
"They've no idea," says Dr VW Parsec. "What happened is they got a load of post-grad research students and gave them all a bit of sky to count the stars in.
"But a couple of the students lost count, one got married and gave up and a few others just made up the numbers. Plus, one of the guys in charge of the project lost his record of who was counting what.
"It's been a cock-up from start to finish. So they just thought of a number and trebled it. The true number could be anything - why not four or five septillion?"
