The findings reveal unusual chemical signatures and offer new insights into the behavior of novas beyond the Milky Way.

red giant star and a cool, white dwarf star about 3,000 light-years away, would be visible with the naked eye once the explosion occurred. In June, NASA predicted that the Blaze Star could explode ...

"In systems like LMC68, less mass is ejected in the nova explosion than is gained by transferring from the cool star," said Evans. "This means that the mass of the white dwarf is steadily increasing.
