A giant planet has just appeared in full surprise

A giant planet named Halla has just appeared, surprisingly around the star Bakedu - which has just exploded into a red giant and should have swallowed the planet.

A giant planet named Halla has just appeared, surprisingly around the star Bakedu - which has just exploded into a red giant and should have swallowed the planet.

According to The Independent , it is a giant Jupiter-like planet called Halla , discovered when scientists observed Bakedu's stage of swelling into a red giant.

Stars in the universe - like our Sun - when they run out of energy will flare up one last time into a red giant, about 1.5 times the size of their previous star. It will then collapse into a tiny white dwarf.

During its final flare, the star may swallow several nearby planets. The Sun is predicted to swallow three nearby planets: Mercury, Venus, and Earth.

But around Bakedu, scientists from the Institute of Astronomy at the University of Hawaii (USA) saw Halla, appearing right after the red giant's explosion reached its peak and began to collapse, in the space that Bakedu had previously occupied to its largest size.

The latest observations confirm that the planet has been orbiting in a stable manner for more than a decade, effectively coexisting with the parent star that is trying to swallow it.

Scientists still don't know exactly why Halla survived. One possibility is that it orbited farther out before the red giant explosion, then slowly moved in. But that's unlikely.

The second possibility is that Halla was born from the collision of two stars, which created the gas cloud from which Halla formed. So Halla could be the 'zombie' of one of the two dead stars, not Bakedu.

Or, simply, it actually survived the red giant catastrophe. That might offer some hope for Earth's future.
