| The sun's magnetic field is about to flip Posted: 06 Aug 2013 02:16 PM PDT Something big is about to happen on the sun. According to measurements from NASA-supported observatories, the sun's vast magnetic field is about to flip. |
| Explosion illuminates invisible galaxy in the dark ages Posted: 06 Aug 2013 12:57 PM PDT More than 12 billion years ago a star exploded, glowing so brightly that it outshone its entire galaxy by a million times. This brilliant flash traveled across space for 12.7 billion years to a planet that hadn't even existed at the time of the explosion -- our Earth. By analyzing this light, astronomers learned about a galaxy that was otherwise too small, faint and far away for even the Hubble Space Telescope to see. |
| New and remarkable details of the sun now available from Big Bear Observatory Posted: 06 Aug 2013 11:55 AM PDT Researchers have obtained new and remarkably detailed photos of the sun with the New Solar Telescope. The photographs reveal never-before-seen details of solar magnetism revealed in photospheric and chromospheric features. |
| Stunning image of nearby galaxy M31 Posted: 06 Aug 2013 06:15 AM PDT A stunning image of M31 has now been captured. M31, also known as the Andromeda Galaxy, is the spiral galaxy nearest to our own Milky Way Galaxy, 2.5 million light years from Earth. It is one of the brightest objects listed in the Messier catalog and has garnered the attention of observers since 964 A.D., when the Persian astronomer al-Sufi wrote about it. |
