On May 2, an international team of astronomers announced that they had discovered three Earth-sized exoplanets, all orbiting the same star (TRAPPIST-1) just 40 light-years from us.
The scientists determined that all three planets are potentially habitable based on their size and temperature.
Now, the same team has discovered that the two innermost planets are rocky and have compact atmospheres, making them less like the hostile planet of Jupiter and more like the rocky planets of Earth, Venus, and Mars. This makes the prospect of life lurking in these faraway worlds even stronger. The researchers published their results today in Nature .... https://www.weforum.org
