Consequently,
10 billion worlds forgotten milky:
What if these silent and forgotten celestial beingsthe white dwarfs, recreated planets where life could flourish? In addition,
Let us forget now the idea that only an active sun can carry habitable worlds. Similarly, A recent study by the Aomawa Shields team invites us to rethink the Cosmic fertility of the Milky Way.
We thought these sterile stars: they could house habitable worlds
Often perceived as cold and 10 billion worlds forgotten milky inhospitable remainswhite dwarfs are actually very manynext to 10 billion in the Milky Way. Nevertheless, So far, scientists have largely ignored them in the quest for habitable worlds, because nuclear fusion is extinguished.
However. Shields and his colleagues showed, thanks to 3D climatic modelsthat a rocky planet in orbit around a white dwarf can offer more living space than a similar planet around a living star like Kepler – 62.
Indeed, the zone habitable is very close to the dead star. This causes a rotation rapideenviron 10 hoursagainst 155 days for the planet of Kepler – 62. This rotation prevents the formation of clouds that are too thick on the day. Therefore, the planet retains a Warm surface and potentially habitable.
Some 10 billion worlds forgotten milky white dwarfs offer ideal conditions for billions of years
However. not all white dwarfs are equal. A rare category, enriched in Neon 22represents about 6 % of the most massive. These stars cool more slowly.
They thus offer a zone habitable stable pendant 8 to 10 billion years. Their stability and distance to planets limit the effects of tidal forces. Consequently, these conditions increase the chances of seeing life appear.
Furthermore, other research reveals that these worlds could capture Enough UV light to allow the Photosynthesis or Abiogenesis. Better still, these planets could even become visible thanks to the next generation telescopes.
The galaxy may tear living planets that we have always ignored
Thus, these stars that we thought Inerts today become credible candidates in the quest for extraterrestrial 10 billion worlds forgotten milky life. More than 10 billion White dwarfs populate the Milky Way, each being able to host at least one planet. It is no longer a needle in a hay boot. From now on, it is an entire galaxy that is offered to us.
This reversal of perspective goes beyond astrophysics alone. He also shakes up our mental models. Have we removed certain signals or life forms simply because they did not meet our expectations? This discovery pushes us to more than intellectual flexibility. In addition, it revives a scientific curiosity essential.
And if life, far from being rare, proved to be Resilient, varied and deeply unexpected ? And if. in the end, the dead stars became the most fertile places to redefine what “living living” means in the universe ?
