NASA is to launch a rocket which will create artificial auroras, the spectacular displays in the sky also known as the northern lights.
Auroras are created when supercharged particles from the sun collide with gases in the Earth's atmosphere.
The resulting ionisation creates a shimmering display of lights in the sky which are typically only seen at the poles of the planet (if you've never seen them before, check them out here).
On Monday the space organisation launched a device into orbit which will artificially create them in order to help scientists better understand the Ionosphere.
It will release blue, green and red vapour into the upper atmosphere, which the scientists will track.
The explosions of colour will be visible over the east coast of the US, between New York and North Carolina - so millions of people will potentially see them. We are feeling rather jealous now.
