Last year, an enormous map of the #cosmos hinted that the engine driving cosmic expansion might be sputtering.

Now physicists are back with an even bigger map, and a stronger conclusion.

Dark #energy is losing steam.

Evolving or weakening dark energy would rewrite our picture of present-day reality.

In the next few months, from its perch atop a mountain in Chile, the Vera C. Rubin Observatory will begin surveying the #cosmos with the largest camera ever built.

Every three nights, it will produce a map of the entire southern sky filled with #stars, #galaxies, #asteroids and @supernovae — and swarms of bright #satellites ruining some of the view.

Swarms of satellites are harming #astronomy.

Here’s how researchers are fighting back.

Christopher Columbus was in peril. Stranded in Jamaica with his starving crew, he had no way out… except one: using his astronomical knowledge to manipulate fear and superstition. What he did on the night of February 29, 1504 remains one of the most audacious moves in the history of a navigator thanks to an eclipse.

Christophe Colomb était en péril. Bloqué en Jamaïque avec son équipage affamé, il n’avait plus d’issue… sauf une : user de son savoir astronomique pour manipuler la peur et la superstition. Ce qu’il fit lors de la nuit du 29 février 1504 reste l’un des coups les plus audacieux de l’histoire d'un navigateur grâce à une éclipse.
