Ahoj
Vzdyt, ale rikaji, ze ta planeta tam vzdy nebyla, je jen polapena.
The planet was forged from gas around a newborn yellowish star in an ancient “globular” star cluster called M4, 7,200 light-years away and within our Milky Way Galaxy. Its existence was first suspected in 1992. Recent Hubble Space Telescope observations allowed Sigurdsson and his colleagues to devise a remarkable tale of the planet’s presumed journey. About 2 billion or 3 billion years ago, as the yellow star and its planet were plunging into the crowded core of M4, they passed near a collapsed, dense and dying neutron star, an object that resulted from some previous explosion of a very massive star. The neutron star had an orbiting companion star. The gravitational tug of war that ensued booted the neutron star’s companion into space. But the neutron star, a weighty competitor, captured the yellow sunlike star and its planet. The sunlike star aged, bloating into a red giant (our sun will do the same one day). The red giant’s gas flowed onto the neutron star, energizing it. The neutron star spun faster. Today, it rotates on its axis 100 times every second and is known as a pulsar. Meanwhile, the red giant’s fuel was exhausted and it turned into a cool, fairly dim white dwarf. The newfound planet now orbits both the white dwarf and the neutron star. “We probably would never have found this planet if it had just stayed with its original star,” Sigurdsson said. “Its history put it in the right place; the interactions helped us see it.”
