WISE 1049-5319

Barnard star is next.

But then the next two after that are WISE 1049 and WISE 0855, which are two brown dwarfs.

So in the closest systems to the sun, brown dwarfs make up half of the closest four.

And they weren't discovered until the mid 2010s, early 2010s, which is relatively recent.

If you're familiar with Zooniverse, you can log on and find us there.

What you do is you look at basically a random area of the sky in infrared light.

So these are images that come from the Wide Field Infrared Survey Explorer, or WISE.

And those images, so we show you what we call a flipbook that shows images of that spot of the sky over a course of about 10 years.
