Scientists have found another world with an atmosphere

Scientists studying a region of outer space near Pluto have discovered the unexpected: a celestial body that has an atmosphere. It was previously believed that extremely tiny objects in space were incapable of hosting atmospheres. The finding could unlock new revelations about planets in our solar system millions of miles away.

What did scientists discover?

The atmospheric discovery of the world, called a trans-Neptunian object (TNO), was described by Japanese astronomers in a publication in the journal Nature Astronomy.
