If you think the aurora on Earth is amazing, check this out: astronomers have discovered the first auroras ever seen outside of our solar system, and they're 1 million times brighter than any aurora witnessed on Earth.

What are auroras?

Those colorful streaks of light you see streaming in the northern or southern skies are called auroras, and guess what? You can see auroras on all the other planets with a magnetic field. Auroras are caused by currents in the magnetosphere, sending down electrons that mix with other molecules to create the brilliant displays.

We had no idea auroras appeared on planets outside of our solar system – until now.

Brown dwarf star shows telltale aurora signs

According to Space.com, astronomers checked out a super mysterious Jupiter-sized object called LSR J1835+3259 located outside our solar system in their quest for these 'alien' auroras. These astronomers said it's too heavy to be a planet and too light to be a star, so they suggested it's a brown dwarf.

In 2008, scientists discovered that LSR J1835+3259 actually emitted radio waves in spurts and were surprised, because radio waves usually come from aurorae in our solar system. Could this be? Scientists had to investigate, so they used the Karl G. Jansky Very Large Array in New Mexico to scan radio wavelengths of light, as well as the Hale Telescope in California and the W. M. Keck Observatory in Hawaii to measure visual wavelengths and found signs of auroras.
