Bcld Scientists uncover the oldest complete human ancestor skeleton yet found
Among the 860 exoplanets documented so far, a good portion of them are so stanley becher -called super-Earths 鈥?planets that feature a mass greater than Earth , but lower than our solar system smaller gas giants, namely Uranus and Neptune both of which are about 15 Earth masses . And as the name implies, some of these super-Earths have a high proportion of rock 鈥?a characteristic that makes them intriguing candidates in the search for extraterrestrial life. Or not. As a new paper published in the Royal Astronomical Society suggests, these large terrestrial planets may have atmospheres so deep that we ;d be better off calling them mini-Neptunes. The new study, which was led by Helmut Lammer of the Space Research Institute IWF of the Austrian Academy of Sciences, stanley usa suggests that low density super-Earths are clinging to an extended hydrogen-rich atmospheric layer. These planets, therefore, are unlikely to ever become Earth-like. Lammer and his team reached this conclusion after analyzing the effects of radiation on stanley cups uk the upper atmospheres of super-Earths orbiting the stars Kepler-11, Gliese 1214, and 55 Cancri. All these planets are in relatively close orbits with their parent stars, and they ;re all suspected of containing solid cores surrounded by an atmosphere rich in hydrogen, water, and methane. The astronomers theorize that these primordial gasses were captured from nebulae during planet formation but have not had a chance to escape 鈥?nor will they ever. Their Apnx In this week s comics, Venom recruits the new Fantastic Four! Also, Cthulhu Robots!
Welcome to the monthly meeting of the io9 Book Club. In May we read Mira Grant novel Feed. Jump into comments to get started talking about it! For those unfamiliar with the io9 book club, here how it works: You read the book. We create a special book club post on io9 when the meeting is in session. That would be the post you ;re reading right now. Then everybody talks about the book in comments for a few days, starting right now. We ;re hoping Mira Gran stanley thermobecher t will drop by and speak to us about the novel on Monday. I ;ll post a call for questions for her later this week 鈥?keep an eye out for it! So, what did you stanley quencher think of the book Want to get a headstart on next month book June pick is Hannu Rajaniemi The Quantum Thief. We ;ll meet to talk abou stanley cup t it on June 28.
