Plutonium in Earth Rocks Signals Long-ago Cosmic Collision

A small lump of rock pulled up from the Pacific Ocean seafloor in 1976 is giving scientists new clues about an ancient cosmic event. More than a hundred million years ago, two neutron stars collided. The resulting energetic kilonova sent a rain of long-lived elements, such as isotopes of plutonium, through space. Eventually, this stellar

The seven hour explosion nobody could explain

Gamma-ray bursts are the most violent explosions in the universe. In a fraction of a second, they can release more energy than the sun will emit across its entire 10-billion-year lifetime. Most are over before you've had time to register them, gone in seconds, minutes at most. So when something arrived on 2 July 2025 that kept going for seven hours, fired three distinct bursts spread across an entire day, and then left behind an afterglow lasting months, astronomers knew immediately they were looking at something completely new.

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…

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.
