Lowell Observatory Celebrates Earth Hour on March 29

Earth hour is a worldwide event held annually at the end of March. People are encouraged to turn off non-essential lights for one hour at 8:30 p.m. as a symbol of their commitment to the health of Earth.   The hope is that participants will be inspired to take action beyond the hour.

Light pollution affects the health of the planet and interferes with astronomers’ ability to study the universe.  Hands-on dark skies activities at the Lowell Earth Hour event will provide visitors with strategies for reducing light pollution and telescope viewing and stargazing activities will inspire guests to implement those strategies.

After 117 years of nearly continuous use, first as a research instrument and later as an educational tool, we will close the Clark Telescope on January 1, 2014 for renovation.

Reopening is expected some time in 2015.  During the closure, guests will still be able to see the Clark dome during most daytime tours.  For evening telescope viewing, we will use the newly renovated 16-inch McAllister Telescope as our primary public telescope.

More than a million guests have seen the Clark Telescope, including Leonard Nimoy, who visited with Carolyn Shoemaker at the telescope during this 1998 film shoot.  The upcoming renovation project will ensure that millions of guests in the future will be able to experience this classic telescope.

Director of Technical Services and telescope expert Ralph Nye has been working on details of planning and preparation for the renovation.  Next comes the dramatic step of removing the telescope, which will happen in January as weather allows.  Stay tuned for renovation updates…

Is Lowell offering public viewing of ISON?

Comet ISON continues to speed toward the sun, brightening as it approaches a November 28 rendezvous with our nearest stellar neighbor.

Since ISON is only visible for a short time in the predawn hours, we don’t plan on any public viewing up through Thanksgiving.  If ISON does survive the sun and is clearly visible, we may then view it.

For more information about the potential fate of ISON, read Matthew’s Knight’s account at  To see a constantly updated calculation of ISON’s speed, and distance to both the sun and Earth, see Emory University’s Distance Calculator at

Lowell Observatory is pleased to announce a new traveling exhibit, The Evolving Universe.  This exhibition, developed by the Smithsonian Astrophysical Observatory (SAO), the Smithsonian’s National Museum of Natural History, and circulated by the Smithsonian Institution Traveling Exhibition Service, reveals the dynamic and evolving universe through breathtaking photographs and informative captions.

The Evolving Universe explores how the stars, galaxies and universe undergo the same stages as life on Earth: from birth, to maturity and, eventually, to death. This remarkable journey from present-day Earth to the far reaches of space and time will be on view at Lowell Observatory from October 12 through January 5 and will then continue to travel on an exciting sixteen city tour through 2017.

DCT’s First Science Results to be Published

Scientists have reached another important milestone with Lowell’s Discovery Channel Telescope (DCT). Comet experts Dave Schleicher and Matthew Knight, along with Stephen Levine, Commissioning Scientist for Lowell’s Discovery Channel Telescope (DCT), observed Comet 10P/Tempel 2 on five nights in early 2013.

These observations helped the team refine the rotational behavior of Tempel 2, results which they’ve described in a paper accepted for publication in an upcoming issue of The Astronomical Journal, a leading peer-reviewed scientific journal.

This represents the first refereed paper accepted for publication that uses DCT data. See an abstract at
