 | Could microbial life exist inside Enceladus, where no sunlight reaches, photosynthesis is impossible and no oxygen is available? To answer that question, we need look no farther than our own planet to find examples of the types of exotic ecosystems that could make life possible on Saturn's geyser moon. The answer appears to be, yes, it could be possible. ...> Full Article |

 | When a white dwarf accretes matter from his larger companion star and after reaching a critical mass ejects it in an explosion a nova occurs. Soft X-rays from classical novae are especially interesting for astronomers: They reveal ongoing residual hydrogen burning after the explosion and so give evidence that some of the accreted material is left on the white dwarf surface after the ejection. In this way the long-term evolution of the white dwarf in a binary system can be studied, for example to answer the question if the nova will later transform into a type Ia supernova, the most luminous supernova type. ...> Full Article |

 | XMM-Newton has been surprised by a rare type of galaxy, from which it has detected a higher number of X-rays than thought possible. The observation gives new insight into the powerful processes shaping galaxies during their formation and evolution. ...> Full Article |
 | An ambitious study of active and inactive galaxies has given new insights into the complex interaction between super-massive black holes at the heart of Active Galactic Nuclei (AGN) and star formation in the surrounding galaxy ...> Full Article |
 | One of the most dynamic events in the interaction between the Sun and the Earth is a 'substorm', an explosive reshaping of the Earth's outer magnetic field. To better understand substorms, scientists in Europe and North America are studying them from space using the Time History of Events and Macroscale Interactions during Substorms (THEMIS) satellites launched by NASA in 2007 and from the ground using a network of all-sky cameras. ...> Full Article |

 | The Pleiades star cluster will have a beautiful encounter with the slender moon in the western sky after sunset on April 8. Usually the moon's brightness overpowers nearby stars, but not when it's such a thin crescent. Binoculars will reveal the spectacle as the moon passes just below the famous Seven Sisters. ...> Full Article |

Using a new technique, two NASA scientists have identified the lightest known black hole. With a mass only about 3.8 times greater than our Sun and a diameter of only 15 miles, the black hole lies very close to the minimum size predicted for black holes that originate from dying stars.

 | Looking for evidence of life on Mars or other planets? Finding cellulose microfibers would be the next best thing to a close encounter, according to new research from the University of North Carolina at Chapel Hill. The cover story for the April issue of the journal Astrobiology, the new research also pushes back the earliest direct evidence of biological material on Earth by about 200 million years. ...> Full Article |
