| NASA's OPALS to beam data from space via laser Posted: 11 Jul 2013 12:14 PM PDT NASA will use the International Space Station to test a new communications technology that could dramatically improve spacecraft communications, enhance commercial missions and strengthen transmission of scientific data. |
| Solar tsunami used to measure Sun's magnetic field Posted: 11 Jul 2013 08:34 AM PDT A solar tsunami observed by NASA's Solar Dynamics Observatory and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun's magnetic field. |
| Stellar monsters do not collide: No hope for a spectacular catastrophe Posted: 11 Jul 2013 07:31 AM PDT One might expect that collisions between the remains of monstrous stars, with masses reaching 200-300 times that of our Sun, would be among the most spectacular phenomena in the Universe. Perhaps they are, but we will unfortunately probably never have the chance to find out. Astrophysicists have discovered that the first such collisions will not occur until billions of years from now. |
| Hubble finds a true blue planet: Giant Jupiter-sized planet located 63 light-years away Posted: 11 Jul 2013 07:28 AM PDT Astronomers using NASA's Hubble Space Telescope have deduced the actual visible-light color of a planet orbiting another star 63 light-years away. If seen directly the planet, known as HD 189733b, would look like a "deep blue dot," reminiscent of Earth's color as seen from space. |
