| Hubble views an old and mysterious cluster Posted: 14 Nov 2013 09:22 AM PST The NASA/ESA Hubble Space Telescope has captured the best ever image of the globular cluster Messier 15, a gathering of very old stars that orbits the center of the Milky Way. This glittering cluster contains over 100 000 stars, and could also hide a rare type of black hole at its center. |
| Hubble reveals first scrapbook pictures of Milky Way's formative years Posted: 14 Nov 2013 08:36 AM PST NASA's Hubble Space Telescope has provided the first visual evidence showing how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today. Perusing Hubble's deep-sky surveys, astronomers traced 400 galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years. |
| Electron beams and radio signals from the surface of the Sun Posted: 14 Nov 2013 07:21 AM PST The sun emits light, but it also emits particle beams. A scientist has now revealed how these beams generate radio waves. These radio waves can tell us about the outer layers of the sun and the interstellar medium without going there. In particular, the radio emissions are produced in small packages, and their shapes are determined by the density changes in the solar wind. |
| Researcher helping to solve moon's water puzzles Posted: 14 Nov 2013 06:41 AM PST Astrophysicists are applying new techniques to better characterize hydrogen, or water, at the moon's poles and map its distribution. |
