Great, not I can totally use this to keep track of the moon. Which totally won't be a waste of money or anything because I'll do this ALL YEAR.

California Institute of Technology (Caltech) astronomer Mike Brown and Kevin Hand from the Jet Propulsion Laboratory (JPL) have detailed the strongest evidence yet that salty water from the liquid ocean beneath Europa's frozen shell makes its way to the surface. The composition of this ocean may well resemble Earth's salty oceans. This new research suggests that there is a chemical exchange between the ocean and the surface, which makes the ocean a richer chemical environment. This exchange means that energy may be going into the ocean.

Note to future filmmakers: If you're going to make a complex movie about space, make sure you run it by Neil deGrasse Tyson first.

The american astrophysicist, cosmologist, host of "Cosmos" took to Twitter on Sunday to share some thoughts on this year's big space movie from Christopher Nolan: "Interstellar." It wasn't intended as a review of the film, but rather - as he emphasises in a Tweet - to highlight the science you can find in the film.

Tyson wrote a similar critique in 2013 following the release of "Gravity," and a scene from Titanic was changed in an updated release of the film after he pointed out the inaccuracies of the stars to James Cameron.

And as you can see, there aren't a whole lot of complaints this time around.

Spoilers ahead if you haven't seen "Interstellar" yet, but if you have seen it, whether it involved worm holes or plot holes, you probably left the theater with a lot of questions.

Here are a few of his thoughts, check his Twitter feed for more.

In #Interstellar: All leading characters, including McConaughey, Hathaway, Chastain, & Caine play a scientist or engineer.

In #Interstellar: And in the real universe, strong gravitational fields measurably slow passage of time relative to others.

Relativity. Gravity. Quantum. Electrodynamics. Evolution. Each of these theories is true, whether or not you believe in them.

In #Interstellar: They reprise the matched-rotation docking maneuver from "2001: A Space Odyssey," but they spin 100x faster.

In #Interstellar: On another planet, around another star, in another part of the galaxy, two guys get into a fist fight.

In #Interstellar: They explore a planet near a Black Hole. Personally, I'd stay as far the hell away from BlackHoles as I can

For the first time in history, scientists are witnessing the formation of a new moon in our solar system. NASA's Cassini spacecraft has detected a new moon forming in the edge of Saturn's rings. Astronomers around the world are amazed about this incredible find, which they have named Peggy.*
