Scientists have detected a powerful glowing aurora in the atmosphere of a celestial body known as a brown dwarf — objects that are kind of neither here nor there, like stars in some ways and like planets in others — that behave more like Earth than like the sun.
Scientists have detected a powerful glowing aurora in the atmosphere of a celestial body known as a brown dwarf, light-years away from our solar system.
The discovery suggests that when it comes to the behavior of their magnetic fields, brown dwarfs — objects that are like stars in some ways and like planets in others — behave more like Earth than like the sun.
