For years, scientists have been debating the odds of life existing on seven fascinating planets orbiting the Trappist-1 star, the most famous planetary system outside our own. The reason? Although several of these planets orbit in their star's habitable zone, the region around a stellar body where liquid water can exist because temperatures are just right, these worlds weren't always so comfortable.  In the past, Trappist-1 exoplanets were subject to much harsher conditions because their parent star used to be much hotter. During those hundreds of millions of scorching years, any water which may have been trapped in the rocks of these planets would have evaporated and dissipated into space, scientists previously thought. That would, of course, ruin the chance of the Trappist-1 planets to develop life as we know it. But a new study, based on a novel modeling technique of the evolution of planetary atmospheres, suggests all may not be lost for life on Trappist-1 exoplanets.

¿Podría la vida en TRAPPIST-1 sobrevivir a las súper llamaradas de la estrella?

En el caso de un planeta enano rojo joven con atmósfera, la mayoría de los rayos X nunca alcanzarían la superficie, pero el mundo joven seguiría estando bañado por la radiación ultravioleta.

El sistema TRAPPIST-1 es el sueño de cualquier escritor de ciencia ficción. Siete mundos del tamaño de la Tierra orbitan alrededor de una estrella enana roja a tan solo 40 años luz de distancia. Tres de esos mundos están dentro de la zona habitable de la estrella. El sistema se extiende a una distancia de menos de 25 veces la distancia entre la Tierra y la Luna. ¡Qué historias épicas tendría una…

Did this a couple days ago. All 7 planets of the TRAPPIST-1 system.

I simply refuse to believe that.

Earth can't be the only planet that can be habitable.

There have been exoplanets that were discovered & theorized to be habitable.

We need the FTL technology to get to Proxima Centauri b, TRAPPIST-1e, f, and g, & some of the Gliese exoplanets.

Life on any of these mysterious planets??? Rocky planets!

I love the Astronomy tag because it ranges from people posting their pictures of the moon and stars to people infodumping about the latest TRAPPIST-1 exoplanet studies, 5k words, no editing

The passion and wonder experienced and shown differently from person to person makes me emotional actually. Its really cute

La evolución del sistema planetario Trappist-1

Alguno de estos siete planetas podría contener una civilización tecnológicamente avanzada

Los planetas son cuerpos que orbitan alrededor de una estrella y tienen suficiente masa gravitatoria como para adoptar formas aproximadamente esféricas que, a su vez, ejercen fuerza gravitatoria sobre objetos más pequeños a su alrededor, como asteroides y lunas. Durante la mayor parte de la historia de la humanidad, los únicos planetas que conocían nuestros antepasados ​��eran los que podían ver…
