So where did all that energy come from that produced those stars since energy can neither be created or destroyed, only changes.
The Butterfly Nebula is a planetary nebula in the Scorpius constellation that contains one of the hottest known stars in the Milky Way.
With an estimated temperature of about 250,000 degrees Celsius, the dying star at the center of this nebula used to be five times the mass of the Sun.
