| Ultrasound for astronomers? A young star's age can be gleamed from nothing but sound waves Posted: 03 Jul 2014 11:24 AM PDT Determining the age of stars has long been a challenge for astronomers. Astronomers now show that 'infant' stars can be distinguished from 'adolescent' stars by measuring the acoustic waves they emit. |
| Controversial clues of two 'Goldilocks planets' that might support life are proven false Posted: 03 Jul 2014 11:23 AM PDT Mysteries about controversial signals from a star considered a prime target in the search for extraterrestrial life now have been solved. The research proves, for the first time, that some of the signals actually are from events inside the star itself, not from the two so-called 'Goldilocks planets,' which were suspected to be just-right for life and orbiting the star at a distance where liquid water potentially could exist. No planets there, just star burps. |
| Posted: 03 Jul 2014 11:21 AM PDT A newly discovered planet is expanding astronomers' notions of where Earth-like—and even potentially habitable—planets can form, and how to find them. At twice the mass of Earth, the planet orbits one of the stars in the binary system at almost exactly the same distance from which Earth orbits the sun. However, because the planet's host star is much dimmer than the sun, the planet is much colder thanEarth -- a little colder, in fact, than Jupiter's icy moon Europa. |
| NASA radio delivered for Europe's 2016 Mars orbiter Posted: 03 Jul 2014 07:27 AM PDT The first of two NASA Electra radios that will fly aboard the European Space Agency's next mission to Mars has been delivered for installation onto the ESA ExoMars Trace Gas Orbiter (TGO). |
