Astronomy is a field that attracts people who are eager to explore the unknown and the vast mysteries of the universe. You can join this journey by discovering more about the Los Angeles Astronomical Society on i-los-angeles.

Founding History

In 1929, a group of 30 local amateur telescope makers came together to form the Los Angeles Telescope Makers Society (LATMS), which is now known as the Los Angeles Astronomical Society. The society’s members were thrilled by fresh discoveries and the growing knowledge of humanity regarding the universe.

Russell W. Porter, who initiated the amateur telescope movement, had a significant impact on LATMS. In August 1920, he began teaching a course in telescope making, with 15 students enrolled: 14 men (mostly employees of Jones & Lamson) and 1 woman (noted as working as a schoolteacher). The course by Russell W. Porter encompassed the construction of Newtonian reflectors, the grinding and polishing of self-made mirrors and their testing, among other things. This group of enthusiasts eventually formed an astronomy club, holding the first meeting of the Springfield Telescope Makers in 1923.

You can find the Los Angeles Astronomical Society at Griffith Observatory, 2800 East Observatory Road, Los Angeles, CA 90027.

Samuel Oschin Planetarium

The Griffith Observatory is home to the Samuel Oschin Planetarium, which deserves mention as well. It is a pioneer of space travel programs and innovations in visual effects. The planetarium is particularly known for its daily live shows, lasting around 60 to 90 minutes. 

The Griffith Observatory opened in 1935, making the Samuel Oschin Planetarium the third of its kind in the United States and the first on the West Coast. It’s worth noting that between 2002 and 2006, the observatory underwent significant renovations, upgrading its facilities with cutting-edge technology, including new projectors, dome structures, sound systems, lighting and seating.

It’s the second-oldest organization in the United States

Springfield Telescope Makers takes the first place. This astronomical observatory in Springfield, Vermont, was established back in 1920 by Russell W. Porter.

Following that, the non-profit corporation LATMS, which is the second on the list, was incorporated in 1929. The society changed its name to LAAS (Los Angeles Amateur Astronomical Society) in 1949 and in 1970, they started using the Lockwood Valley Dark Sky Site.

Since 1987, LAAS has been running the Garvey Ranch Park Observatory and its telescope workshop located in Monterey Park, California.

In 2012, the Ford Observatory was generously donated to LAAS.

Promoting astronomy in Los Angeles

The Los Angeles Amateur Astronomical Society strives to foster the public’s interest in science and the universe, optics and telescope making, as well as the subjects associated with it. To fulfill this mission, the society hosts:

  • Public Star Parties. For example, LAAS members organize a star party at Griffith Observatory every month, usually on a Saturday during the first week of the month. The event takes place from 3:00 pm to 9:30 pm (and until 10:30 pm in the summer). Members bring their telescopes, inviting everyone to discover the marvels of the night sky.
  • Each month, on Saturdays closest to the new moon, the Steven Kufeld Astronomical Site in Lockwood Valley invites current LAAS members and their guests.
  • Public outreach programs for schools and a range of community events throughout Los Angeles County. If you would like to set up an outreach event for a school or organization, just fill out a request form on the website.
  • Every Wednesday evening, the Garvey Ranch Observatory in Monterey Park opens its doors to both the public and society members. The observatory welcomes guests from 7:00 pm to 10:00 pm.

With these efforts, astronomy becomes more accessible to everyone. Residents of Los Angeles can now experience the breathtaking beauty and marvels of our universe firsthand.

Partnership

Each year, more and more people are drawn to the wonders of astronomy. There are a few key reasons for this growing interest.

  • Astronomy is one of the oldest sciences out there and it keeps evolving. With the help of new technologies, today’s enthusiasts can explore the mysteries of space like never before.
  • The vastness and mystery of the universe captivate many, fueling a desire to uncover the unknown and understand how everything functions. 
  • The night sky, with its countless stars, offers a stunning visual display, making it easy to appreciate the aesthetic pleasure and wonder of our observations. Even amateur astronomers can make their own discoveries by tracking the movements of stars, comets, meteorites and more.

Griffith Observatory and the Los Angeles Astronomical Society work together beautifully, enhancing each other’s efforts. This partnership enables the residents of Los Angeles to discover the marvels of astronomy, expand their understanding and participate in exciting events. It’s especially amazing to see people from various backgrounds and ages come together, all sharing a passion for astronomy and everything that comes with it.
