Propulser un engin spatial grâce à la lumière: le projet de scientifiques pour atteindre Alpha Centauri

Un voyage épique de 4,37 années-lumière sépare les humains d'Alpha Centauri, notre plus proche voisine stellaire, mais une équipe de l'université Texas A&M vient de dévoiler une technologie qui pourrait nous en rapprocher et, plus largement, bouleverser les possibilités en termes d'exploration spatiale.

"Interstellar Mission to a Black Hole"

No word of a lie, one of the appeals of vampirism is living long enough to see shit like this happen.

Interstellar Mission to a Black Hole | Centauri Dreams

OK, there's one thing bothering me regarding “Alien: Earth”: If you're on a decades-long deep space mission that requires cryo pods, how do you have cats on board the spaceship? Do they have their own little cryo pods? Or are they just semi-feral and evolve into a new species over time, like in “Red Dwarf”?

There is a red cat briefly seen on the Maginot. If I recall correctly, there is also a cat on the Nostromo. How?

I mean, sure, cats have historically been part of ship crews, but in space?

How to use fusion to get to Proxima Centauri's potentially habitable exoplanet

Proxima Centauri b is the closest known exoplanet that could be in the habitable zone of its star. Therefore, it has garnered a lot of attention, including several missions designed to visit it and send back information. Unfortunately, due to technological constraints and the gigantic distances involved, most of those missions only weigh a few grams and require massive solar scales or pushing lasers to get anywhere near their target.
