Astronomers have discovered a Jupiter-size planet that "shouldn't exist" after the sudden and violent expansion of its host star.
The gas giant 8 Ursae Minoris b — also known as Halla — is a "hot Jupiter" planet located 520 light-years from Earth. The enormous world seemingly faced certain destruction after its host star, Baekdu, ballooned to thousands of times its original size to devour any planets in its orbit.
