Astronaut Scott Kelly tweeted a breathtaking time-lapse video of the Aurora Borealis, or Northern Lights, from the International Space Station. The video shows Aurora like an eerie river appearing over the Earth's horizon as the sun peeps into view, the Telegraph reported.

Kelly is on his 141st day of his year-long stint on the International Space Station, sharing some updates on Twitter.

In the video, the color turns to a bright violet as it approaches the sun. Prior to the video, Kelly also posted a photo of the scenario noting that the lights are very noticeable because of the sun.

ISS is travelling at about 17,000 mph relative to the surface that allowed him to capture the setting of the Aurora as it hit the while light from the sun, the Verge reported.

The Northern Lights display occurs when explosions on the surface of the sun launch huge amounts of charged particles into space, according to the British Geological Survey (BGS).

The captivating light happens when particles in the Earth's magnetic field collide with gas molecules in the atmosphere.

The next day, Aurora's beauty was still seen from ISS and was captured by Kelly.
