GEMINIDS 2009 - 0 views

  •  
    This weekend, Earth passed through a stream of debris from 3200 Phaethon. In 1983 Whipple identified Phaethon like the parent of Geminid meteor stream. But it has never displayed unambiguous cometary activity. The Geminids provide the most impressive meteor display of any of the annual showers.

Arxiv - Orbital Elements of Comet C/1490 Y1 and the Quadrantid shower - 0 views

  •  
    The Quadrantid shower, one of the most intense showers, has been observed at the beginning of January each year. However, the origin of the meteors is still unknown. It was Hasegawa (1979) who first suggested comet C/1490 Y1 to be the likely origin of the shower based on the historical records of East Asia.

Five Amateurs Win Comet Prize - 0 views

  •  
    The 2009 Edgar Wilson Award honors amateur astronomers who discovered five different comets in the last 12 months, proving that backyard comet hunting still thrives in this age of automated professional sky patrols.

Sunday Night's Virginia Fireball: a Meteor, Not a Rocket Re-entry - 0 views

  •  
    The confusion over whether the great Virginia fireball Sunday night was a meteor or a Russian rocket re-entry seems to be resolved - in favor of a meteor

Reassessing the Source of Long-Period Comets - 0 views

  •  
    We present numerical simulations to model the production of observable long-period comets (LPCs) from the Oort Cloud, a vast reservoir of icy bodies surrounding the Sun. We show that inner Oort Cloud objects can penetrate Jupiter's orbit via a largely unexplored dynamical pathway, and they are an important, if not the dominant, source of known LPCs.

McNaught Bags His 50th Comet - 0 views

  •  
    McNaught has just discovered his 50th comet. He spotted it, as he does most often these days, on images taken with the 20-inch (0.5-meter) Uppsala Schmidt telescope at Siding Spring Observatory in Australia.

New Comet Discovery: C/2009 R1 (McNAUGHT) - 0 views

  •  
    IAU Circular nr.9071, issued on 2009, Sep. 10, announces the discovery of a new comet by R. H. McNaught, named C/2009 R1 (McNAUGHT). This comet may reach magnitude 5 at the end of June 2010, but the elongation will be very small (only 18 degree on June 27, 2010) and so the observing conditions.

Giant planet holds comets hostage - 0 views

  •  
    Jupiter has been caught 'kidnapping' comets when they venture too close, forcing them to become temporary satellites of the great planet before they are slingshot away or spiral into Jupiter, according to new data presented at this week's European Planetary Science Congress (EPSC) in Potsdam, Germany.

Jupiter captured comet for 12 years in mid-20th Century - 0 views

  •  
    Comet 147P/Kushida-Muramatsu was captured as a temporary moon of Jupiter in the mid-20th century and remained trapped in an irregular orbit for about twelve years.

Comet Holmes produced mini-comets - 0 views

  •  
    The outburst of Comet 17P/Holmes was so violent that it blew huge chunks of the comet's surface clean off, according to a new analysis of images taken in November 2007.

Asteroid Juno Grabs the Spotlight - 0 views

  •  
    Toward the end of September, the sun will turn a spotlight on the asteroid Juno, giving that bulky lump of rock a rare featured cameo in the night sky.

Jupiter sports new 'bruise' from impact - 0 views

  •  
    A new black spot about as big as the Earth has been found on Jupiter. Astronomers say it was caused by an impact.
