Nasa, scoperte sette sorelle della Terra

Some 40 light-years from Earth, a planet called TRAPPIST-1e offers a heart-stopping view: brilliant objects in a red sky, looming like larger and smaller versions of our own moon. But these are no moons. They are other Earth-sized planets in a spectacular planetary system outside our own. These seven rocky worlds huddle around their small, dim, red star, like a family around a campfire. Any of them could harbor liquid water, but the planet shown here, fourth from the TRAPPIST-1 star, is in the habitable zone, the area around the star where liquid water is most likely to be detected. This system was revealed by the TRansiting Planets and PlanetIsmals Small Telescope (TRAPPIST) and NASA's Spitzer Space Telescope. The planets are also excellent targets for NASA's James Webb Space Telescope. Take a planet-hopping excursion through the TRAPPIST-1 system

New Planets

Niente da dire, dal punto di vista scientifico la scoperta di un sistema solare relatvamente vicino alla terra  con sette pianeti dalle caratteristiche tali da poter verosimilmente ospitare forme di vita evolute è importantissima.
Ma che abbia praticamente oscurato quella che di 18000 casette di legno, necessarie per le aree terremotate, ne sono state consegnate solo 180 è veramente intollerabile.

This 360-degree panorama depicts the surface of a newly detected planet, TRAPPIST-1d, part of a seven planet system some 40 light years away. You can explore this artist’s rendering of an alien world by moving the view using your mouse or your mobile device.

The depiction is based on the latest scientific data about this planetary system, and this world’s sister planets can be seen as bright points of light in a dark sky. Each world is roughly in Earth’s size range, in terms of both mass and diameter. Further observations will be needed to determine whether any or all of these worlds might be habitable.
