Podcast Description
It's a big sky -- someone has to watch it. This quick, weekly audio broadcast explores the astronomy news of the day, with topics ranging from dark matter to nearby planets. Join hosts Carol Christian of the Space Telescope Science Institute and Jim O'Leary of the Maryland Science Center for the latest buzz on space. SkyWatch also includes HubbleWatch, a monthly round-up of news from NASA's Hubble Space Telescope.

CleanShow 390: Finding The Milky Way's Black Hole | Astronomers have suspected that a gigantic black hole resides at the center of our Milky Way galaxy for some time now, but they can't say for sure. Now scientists are hoping to image this mysterious object with a world-wide array of radio telescopes. | 26 4 12 | Free | View In iTunes |

CleanShow 391: HubbleWatch for April 2012 | The universe's mysterious dark matter gets a little more mysterious. And Hubble celebrates its 22nd birthday by showing off its keen vision, capturing an immense and detailed view of a nearby star-forming region. | 25 4 12 | Free | View In iTunes |

CleanShow 389: Forecast From Space | What do extrasolar planet systems have to do with Earth weather? Perhaps a lot. The United Kingdom Met Office, which, handles the UK national weather service, has a research team looking at applying space-weather models to the Earth, Sun and our solar system. If the models can explain what is seen in other planetary systems, different from our own, then they can help us understand the physics that drives our weather and climate. | 19 4 12 | Free | View In iTunes |

CleanShow 388: Asteroid on Its Way | An asteroid known as 2012 DA14 was discovered in Feb 2012 and is on track for close swing by Earth in 2013. Many reports circulated about it hitting our planet, but that's not going to happen. Astronomers are monitoring the asteroid for calculations on its future passes. | 12 4 12 | Free | View In iTunes |

CleanShow 387: Black Hole Clues in Shredded Galaxy | The existence of black holes has been known for some time, and it can seem like we know all about them. We know that individual, stellar-size black holes form at the end of a massive star's life. We also know that supermassive black holes exist in the center of galaxies, and it is assumed that they form from the merger of medium-size black holes. Yet these medium-size objects have not been found. Now an x-ray telescope's discovery suggests they do exist. New observations with the Hubble Space Telescope and the SWIFT telescope yield new clues. | 5 4 12 | Free | View In iTunes |

CleanShow 386: Explosions on Venus | Some strange, gigantic explosions, which seem to be fueled by fueled by solar energy, have been detected just above the surface of the planet Venus. These powerful explosions have also been detected in the past near Earth, Saturn and possibly Mars. | 29 3 12 | Free | View In iTunes |

CleanShow 385: Dark Matter Puzzle | Although the concept of dark matter has been around for a long time, scientists aren't really clear on what it is. Originally, scientists thought that dark matter was associated with and "stuck to" the luminous matter we see - stars, galaxies, clusters of galaxies and other groupings. But new observations confirm a suspicion that emerged a few years ago: dark matter does not always behave exactly like normal matter. | 22 3 12 | Free | View In iTunes |

CleanShow 384: Deep Space Outpost | NASA is studying a plan for a "human-tended waypoint" near the Moon's far side that could oversee robotic operations on the lunar surface -- and be a jumping-off point for more complex missions. | 15 3 12 | Free | View In iTunes |

CleanShow 383: HubbleWatch for March 2012 | Famously fractious star Eta Carinae is replaying one of its greatest hits -- an explosion witnessed on Earth 170 years earlier. And Hubble has discovered a new type of planet -- a hot super-Earth made up mostly of water and ice. | 14 3 12 | Free | View In iTunes |

CleanShow 382: Betelgeuse's Demise | Earth might someday have a second sun in the sky, at least for a few weeks. This would occur when one of the brightest stars in the sky explodes as a supernova. The star is Betelgeuse, the red giant that marks the shoulder of the northern winter constellation Orion the hunter. But don't count on it to happening anytime soon. | 8 3 12 | Free | View In iTunes |

CleanShow 381: Venus Changing Rotation | Venus is sometimes called a sister planet to Earth but has important differences. While similar in size, Venus has a much thicker atmosphere and is unbearably hot at the surface. Venus has been studied by many spacecraft, and recently the Venus Express, launched in 2005, probed its atmosphere and surface. Results from infrared observations indicate something may have changed in Venus' rate of rotation, posing an intriguing mystery for researchers. | 1 3 12 | Free | View In iTunes |

CleanShow 380: Supernova Mystery Solved | Type 1a Supernovae are important objects in the study of the cosmos and, in particular, the expansion and acceleration of the universe. While much is known about the signature of the Type 1a supernovae, such as how fast the light from the explosion increases and the rate at which it decays, the cause of the explosion was not entirely known. | 23 2 12 | Free | View In iTunes |

CleanShow 379: Deep-fried Planets | Recently, two Earth-sized planets were discovered around a dying star. The star has passed beyond its red giant stage, in which it would have engulfed the planets, and the planets survived. The discovery provides new information about how planets affect the course of a star's evolution. | 16 2 12 | Free | View In iTunes |

Not enough
Excellent little podcast this but wish it was weekly as it's only 4 or 5 mins long
