"The Journey to Palomar," a 90-minute film by Todd and Robin Mason, will air nationally on PBS stations on 10 Nov 2008. The film tells the story of George Ellery Hale's yearning for ever larger telescopes while creating the new science of astrophysics at the beginning of the Twentieth Century. Mount Wilson Observatory plays a major role in this wonderful saga. The Mason's website about their years of effort and devotion in creating this memorial to one of America's most important and least-known scientists. |

Dr. Robert Jastrow, Director of the Mount Wilson Institute from 1992 to 2003, passed away on February 8, 2008. An early advocate of planetary exploration, Dr. Jastrow established NASA's Goddard Institute for Space Studies in New York City in 1961. The Institute works closely with his nearby alma mater, Columbia University. Dr. Jastrow was also a best-selling author and popular speaker whose gift for clearly explaining science led to regular television appearances. A biographical sketch has been published by the George C. Marshall Institute, a center for science and public policy co-founded by Dr. Jastrow in 1984. |

Using the CHARA Array on Mount Wilson astronomers have imaged the face of Altair, a familiar star in the summer sky. New technology allowed the light from four of the interferometer array's telescopes to be combined for a two-dimensional view. Details, graphics and video are available in the press release from the National Science Foundation. |

All Clear The fire burning in the Angeles National Forest is out, all roads in the area are open and the observatory is open to visitors.. |
| 22 Sep 2006 |
Roads leading to the observatory have been re-opened after a closure caused by a nearby fire. Because the fire is not contained, however, conditions can change at any time. For those with important business at the observatory, the US Forest Service Incident line at (626) 574-5208 has the latest information. Observers on the 60-inch telescope should check that telescope's status line for the latest on the roads and other conditions, such as falling ash, that may affect their observing sessions.. |
| 21 Sep 2006 |
A fire has caused a temporary closure of all roads leading to the observatory. Currently, only residents and employees can gain access to the observatory. Road re-openings will be announced here as they occur.. |

The CHARA Array at Mount Wilson is in the news once again following two important presentations at the annual conference of the American Astronomical Society in Washington, DC. Utilizing the CHARA Array's unprecedented resolution, a long-standing mystery concerning the brightness of Vega -- one of the night sky's brightest stars -- was solved by a team from the National Optical Astronomy Observatory in Tucson led by Jason Aufdenberg. High-resolution studies with CHARA have shown that the large star's fast rotation rate and the angle from which we view the star explain why Vega appears to shine more brightly than stellar theory says it should. But a team from the University of Michigan led by David Berger has added fuel to a new mystery concerning red dwarfs, the most common type of star in our galaxy. Berger's team found that red dwarfs are larger than expected for the amount of light that comes to us from their relatively cool surfaces. For more details see a report on the web site of Sky and Telescope Magazine. |

RTMC Expo, a major amateur astronomy conference held each Memorial Day weekend, included presentations on Mount Wilson Observatory following this year's theme of The History of Astronomy. Shelley Bonus gave a presentation on Hubble and Humason: The Odd Couple of Mount Wilson and Mike Simmons marked the observatory's centennial with Astronomy Comes of Age: Mount Wilson's First Century, 1904-2004. A panel discussion, Personal Reminiscences of the Early Days on Mount Wilson, featured Mount Wilson Institute Assistant Director Don Nicholson (son of astronomer Seth Nicholson) and Jane Sanford Lewis (daughter of astronomer Roscoe Sanford), who recalled conditions, people and events on the mountain beginning in the 1920s. The conference's keynote presentation also touched on Mount Wilson as filmmakers Todd and Robin Mason discussed their upcoming documentary, The Journey to Palomar, which traces the life of observatory founder George Ellery Hale. |

Mount Wilson Observatory benefactor Paul Gerstley passed away on April 20, 2004. Paul was largely responsible for upgrading the Hooker telescope and turning it into a world-class instrument for research in the 21st century. Paul also provided substantial contributions to remodel Mount Wilson's historic Kapteyn Cottage and refurbish the Mount Wilson Astronomical Museum. Upon hearing of Gerstley's passing, Dr. Robert Jastrow, former Director of the Mount Wilson Institute, summed it up perfectly when he said, "A light has gone out in the universe". A memorial service was held in Chicago, his birthplace, on May 2. |
