NASA is making a big announcement on Monday.
About something it found on Mars.

Yes, NASA says it has a "major science finding" to share, but there are some good indicators that no, it's not aliens.
The biggest clue is probably the people doing the announcing. It's mostly planetary scientists and geophysics grad students set to talk on Monday, which gives this a better chance of being something about Mars' surface or structure.
Who would you even get to talk about first contact, anyway? Someone from the UN? Captain Picard? (Video via Paramount Pictures)
Anyway, right now the media's favorite speculation is NASA has found liquid water.
That's not as exciting as aliens, but it would also be better evidence for the existence of life elsewhere than we have today.
Still not even microbial life, though, and NASA makes sure to knock down such rumors whenever they crop up.
NASA will be streaming its conference at 11:30 Eastern time on its website.
