One-hundred million light years away from Earth, an unusual supernova is exploding.

That exploding star —which is known as “supernova LSQ14fmg”—was the faraway object discovered by a 37-member international research team led by Florida State University Assistant Professor of Physics Eric Hsiao. Their research, which was published in the Astrophysical Journal, helped uncover the origins of the group of supernovae this star belongs to.

This supernova’s characteristics—it gets brighter extremely slowly, and it is also one of the brightest explosions in its class—are unlike any other.
