A giant planet named Halla has just appeared surprised around the star Bakedu – which has just exploded into a red giant and should have swallowed the planet.
Theo The Independentit’s a Giant Jupiter-like planet called Hallawas discovered when scientists observed the phase Cooked swells into a red giant.
Stars in the universe – like our Sun – when depleted of energy will explode one last time into red giants, about 1.5 times larger than before. Then it will collapse into a small white dwarf.

During its final eruption, the star may have engulfed several nearby planets. The Sun should swallow 3 nearby planets: Mercury, Venus and Earth.
But around Bakedu, scientists from the Institute of Astronomy at the University of Hawaii (USA) saw Halla, which appeared shortly after the outbreak of red giants reached its peak and began to collapse in the region. bigger size.
The latest observations confirm that the planet has remained in a stable orbit for over a decade, in effect coexisting with the parent star trying to swallow it.
Scientists still don’t understand why Halla survived. One possibility is that it circled further before the red giant erupted, then slowly moved away. But this possibility is very small.
The second possibility is that Halla was born from the collision of two stars, which created a gas cloud from which Halla formed. So Halla could be “zombie” of one of the two dead stars, not Bakedu.
Or, to put it simply, he actually survived a red giant disaster. This might offer some hope for Earth’s future.
