It's that time of year again - Halloween. Though Australia's not quite as big on the holiday as Americans (or even Brits), some of us are coming around to the spookiest holiday in the Western world.

Even if you're not into Halloween, you can definitely appreciate these innovative jack-o-lantern designs, courtesy of last week's Annual Pumpkin Carving Competition hosted by NASA's Jet Propulsion Laboratory.

NASA's competition brings together science and art, with participants creating intricately designed and mechanised pumpkins, far more elaborate than what people usually have on their porches.

Mechanical engineer and NASA employee, Aaron Yazzie, live-tweeted the event by sharing some pretty epic videos and pictures from the competition last Thursday. 

Some notable entries this year include a jack-o-lantern with a rotating model of the solar system inside; a pumpkin that looked like a giant meteor about to hit Earth; and another that whizzed around like a Martian spacecraft. 

In addition to all these ingenious Halloween pumpkins, NASA's 2015 Halloween version of our Sun has been making the rounds once again. Here it is in all its glory:

Happy Halloween!
