Des astronomes ont retrouvé la trace de deux étoiles qui sont passées près du Système solaire !

Elles semblent fixes dans notre ciel. Pourtant, toutes les étoiles sont en mouvement. Et deux d’entre elles ont rendu une visite à notre Soleil. C’était il y a plus de 4 millions d’années. Mais les traces sont toujours là…

New study casts doubt on the likelihood of Milky Way collision with Andromeda - Durham University

Universe expected to decay in 10⁷⁸ years, much sooner than previously thought

The universe is decaying much faster than thought. This is shown by calculations of three Dutch scientists on the so-called Hawking radiation. They calculate that the last stellar remnants take about 1078 years to perish. That is much shorter than the previously postulated 101100 years.

A new study suggests ancient carvings might represent a calendar marking a comet strike, potentially linked to the Younger Dryas event—one of humanity's major milestones. This cooling event drastically changed ecosystems and may have pushed human societies toward adaptation and innovation. If true, these carvings offer a glimpse into how early civilizations recorded cosmic events.
