| New clues to determining the solar cycle Posted: 03 Sep 2014 05:41 PM PDT Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun's activity, known as solar maximum, is a time of numerous sunspots, punctuated with profound eruptions that send radiation and solar particles out into the far reaches of space. However, the timing of the solar cycle is far from precise. |
| Posted: 03 Sep 2014 01:35 PM PDT Keeping upright in a low-gravity environment is not easy, and NASA documents abound with examples of astronauts falling on the lunar surface. Now, a new study suggests that the reason for all these moon mishaps might be because its gravity isn't sufficient to provide astronauts with unambiguous information on which way is 'up'. |
| Newly identified galactic supercluster is home to the Milky Way Posted: 03 Sep 2014 10:33 AM PDT Astronomers using the Green Bank Telescope -- among other telescopes -- have determined that our own Milky Way galaxy is part of a newly identified ginormous supercluster of galaxies, which they have dubbed 'Laniakea,' which means 'immense heaven' in Hawaiian. |
| 'Brightpoints': New clues to determining the solar cycle Posted: 03 Sep 2014 07:47 AM PDT Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. However, the timing of the solar cycle is far from precise. Now, researchers have discovered a new marker to track the course of the solar cycle -- brightpoints, little bright spots in the solar atmosphere that allow us to observe the constant roiling of material inside the sun. |
| Cosmic forecast: Dark clouds will give way to sunshine Posted: 03 Sep 2014 06:17 AM PDT Lupus 4, a spider-shaped blob of gas and dust, blots out background stars like a dark cloud on a moonless night in this intriguing new image. Although gloomy for now, dense pockets of material within clouds such as Lupus 4 are where new stars form and where they will later burst into radiant life. |
| Scientists' work may lead to mission to find out what's inside asteroids Posted: 02 Sep 2014 05:51 PM PDT Future asteroid mining operations and how we deal with an impending strike could be influenced by research on a potential NASA mission. |
