Commercial Space Flight.jpg

Commercial Space Update 

Elon Musk’s SpaceX, Jeff Bezos’ Blue Origin, and Richard Branson’s Virgin Galactic are just some of the commercial ventures hoping to be part of the first wave of private human spaceflight, as well as providing satellite launch services at lower cost than older players in the industry. With NASA human spaceflight pivoting to a lunar return prior to heading for Mars, it’s a fair question whether there will be commercial companies already operating on or around the Moon by the time NASA gets there with crewed Orion spacecraft. We’ll try to sort out likely near-term events in this ongoing evolution. 

Fri, March 9 | 8 p.m. | Planetarium​

Black Hole.jpg

Guest Lecture: Shelley Bonus Neutron Stars, Colliding Black Holes, and Gravitational Waves

Guest lecturer Shelley Bonus will review the cuttingedge discoveries in the new field of gravitational wave astronomy, a field made possible by the first detection of gravity waves in 2015 by the Laser Interferometer Gravitational-wave Observatory (LIGO), which provides information about the universe not obtainable by any previous type of scientific tool.

​ ​​​TILT! Equinoxes and Solstices Explained 

As we move through the Vernal Equinox and mark the beginning of Spring on March 20, most of us are only vaguely aware of what the equinoxes and solstices actually are. Using our Digistar planetarium projector and other imagery, we’ll try to remedy this disconnect from the natural world, which makes most modern humans vastly less aware of the rhythms of the sky than our ancestors were. We’ll also try to dispel some myths, like that egg story…. 

Fri, March 23 | 8 p.m. | Planetarium

Shelley R. Bonus.jpg​​

Guest Lecture: Shelley Bonus What’s Your Zodiac Sign and Why? Astronomy/ Astrology Myths and Facts 

Guest lecturer Shelley Bonus will give her lively take on the relationship between astronomy and astrology, two 38 once-synonymous, but now-sundered ways of looking at the sky. Fri, March 30 | 8 p.m. | Planetarium Messier Marathon Observing Report Find out about French 18th-century comet hunter Messier’s list of nuisances, which became a catalog of the brightest galaxies, star clusters, and nebulae in the northern sky. Our planetarium director will also report on his efforts March 17 to complete a dusk-to-dawn “Messier Marathon” to view all 110 objects in a single session, possible only in March and April. 

Fri, April 6 | 8 p.m. | Planetarium 


Special Observing Event: A Crescent Moon and Famous Double Star 

Come look at the 5-day-old crescent Moon, with its dramatically lit crater Theophilus. Then turn your gaze to the famous visual binary of Mizar and Alcor, the middle stars in the handle of the Big Dipper. Mizar was the first telescopic binary (double star) ever documented, in the early 17th century. We’ll begin in the planetarium, then head outside for viewing through telescopes with guidance from our planetarium director. Dress warmly! 

Fri, April 20 | 8 p.m. | Planetarium 

Mars Insight.jpg

Mars INSIGHT Mission Preview 

The Mars INSIGHT mission, scheduled to launch May 5 for a landing on the Red Planet November 26, carries a suite of instruments designed to probe the interior structure and heat flow characteristics of Mars. We’ll preview the mission, take a look at the status of Mars programs worldwide, and talk about the Mars 2020 rover mission in preparation now at JPL.

Star Planner.jpg

Summer Star Party Planner

Gatherings of amateur astronomers to observe the evening sky are called “star parties,” and summer presents good opportunities for beginners to attend these events without having to deal with winter’s cold and travel hazards. We’ll clue you in on where and when to go, and what to bring to be a welcome star party visitor and participant. You will even have a chance to sign up for information on joining a group of amateur astronomers at a dark sky site in July. 

Fri, May 4, 11 | 8 p.m. | Planetarium 

Moon Travel.jpg

Guest Lecture: Shelley Bonus NASA, ESA, and Private Investors Back to the Moon? 

Why, and What about Mars? The Moon is once more the near-term target for NASA, the European Space Agency, and private groups. Guest lecturer Shelley Bonus will explore these developments and how they relate to human prospects on Mars. 

Fri, May 18 | 8 p.m. | Planetarium 

39 Parker Probe.jpg

39 The Parker Solar Probe: Touching the Sun ​

Launching this summer and using the gravity of Venus, the Parker Solar Probe will gradually lower its orbit to within 4 million miles of the Solar photosphere, the apparent “surface” of the Sun. Understanding this region will help develop reliable forecasting for spaceweather events that directly impact technology and life on Earth. If all goes well, Parker will spend the next 7 years unlocking the secrets of this unexplored region, while also becoming the fastest-moving object ever created by humans. 

Fri, June 1, 29 | 8 p.m. | Planetarium 


Guest Lecture: Shelley Bonus Jupiter & Europa: Myths and Science 

Guest Lecturer Shelley Bonus will provide updates on the newest findings from the Juno probe at Jupiter, and the status of the proposed Europa Clipper mission to investigate the habitability of the subsurface ocean of Jupiter’s icy moon. (By the way, Juno, the wife of Jupiter, was able to peer through clouds to reveal Jupiter’s true nature and actions. The two didn’t always get along. Find out why, in this celestial soap opera.) 

Fri, June 8 | 8 p.m. | Planetarium 


Guest Lecture: Shelley Bonus Saturn Update! 

New Proposed Missions Guest lecturer Shelley Bonus presents the latest updates on Saturn and proposed missions to explore two of its moons. Surprised by the discovery of salty water plumes shooting from the ice-covered moon Enceladus, NASA is considering a new mission, “Enceladus Life Finder,” to sample and analyze the makeup of the plumes, which could include amino acids that might be a sign of life in that subsurface ocean. Another proposed mission, “Dragonfly,” would involve flying a probe like a nuclear quadcopter in the atmosphere of Saturn’s large moon Titan, surveying for possible life.
