Your place in space

Seen and unseen

By Bill Nye, Planetary Society CEO

As has become our tradition, this issue of The Planetary Report looks back on the year in pictures. As I hope you expect, 2023’s images are fantastic and serve to recap this year’s events and achievements in space exploration. They’re also a wonderful way to invite people to share the joy of discovery. Whether a person is a space professional, a night sky enthusiast, or new to planetary science, everyone can appreciate these pictures. They’re beautiful.

Along with images captured with cameras that mimic our human vision, there are astonishing things out there that we can’t see without a little tinkering. Many of the images in this issue were sent down from the James Webb Space Telescope, which “sees” wavelengths in the infrared. These images are exciting and vital for our understanding of the Cosmos. Then there are those exoplanets that we know are there only because of how they momentarily obscure the light of their host stars beyond. And how about those cosmic phenomena that we can’t see at all because we aren’t sure that they’re even there, though we hope and expect that they are? What about our search for evidence of extraterrestrial life? Will we even know it if we see it? I think about this every (Earth) day.

As you’ll read later in this issue, The Planetary Society has been working year-round to advance the search for new insights about space, advocating to make further discoveries in our Solar System and beyond so that humanity might see more than ever before — more spectacular images, leading to more astonishing discoveries and more insights about what it means to exist in this Universe.

Your membership makes this work possible, and I thank you again for your support. I hope that this year-end roundup of stunning space images reminds you just how far exploration has advanced in the last 12 (Earth) months. This progress in our ability to see further into the Cosmos wouldn’t happen without people like you believing that it’s all worth seeing.

Eclipse 2024

Total solar eclipses are fairly rare, and it’s even more uncommon for one to pass over huge, populated areas. That’s why we’re extraordinarily excited about the total solar eclipse that will pass over large portions of North America on April 8, 2024. An estimated 635 million people will be able to watch the Moon obstruct at least part of the Sun, including a rarer few who will see the Moon entirely block the Sun for a few minutes.

Eclipse-o-rama 2024: An eclipse festival for space enthusiasts

The Planetary Society is developing a once-in-a-lifetime opportunity to view the great North American total solar eclipse of 2024 with your fellow Planetary Society members. Join CEO Bill Nye and others in the Planetary Society family in Fredericksburg, Texas — one of the best viewing locations in the heart of the Texas Hill Country.

It will be two days of science, art, music, and space! Our family-friendly festival will feature special talks on astronomy and planetary science, exhibitor and vendor booths, star parties, music, food, and an unparalleled view of the eclipse.

The last total eclipse in North America was in 2017, and the next one after this one won’t happen for another two decades — in 2045! That’s why The Planetary Society is excited to offer a very special opportunity to watch this eclipse in person with your fellow members.

A solar eclipse is a remarkable celestial event, blending scientific wonder with cultural significance and an undeniable sense of magic. There’s no better place to watch the eclipse than with all your favorite space friends. Come join us! Go to to learn more.

The Eclipse Explorer Junior Ranger booklet

The Planetary Society is excited to once again collaborate with the U.S. National Park Service to provide an engaging and educational eclipse experience for children and families. The Eclipse Explorer Junior Ranger booklet features interactive activities, guidance from Planetary Society CEO Bill Nye, and more! Kids who complete the booklet will receive a badge and become a certified junior ranger. Booklets are available in participating parks.

Beyond the horizon: The Planetary Society campaign to create space for everyone

The Planetary Society's leadership is proud to announce that we’re embarking on the final public phase of our most ambitious comprehensive fundraising campaign ever. The goal for the effort — called Beyond the Horizon: Creating Space for Everyone — is to raise $40 million over five years to explore worlds, search for life, defend Earth, and grow and strengthen the Society. With the help of our members and donors like you, through this campaign we seek to connect everyone with the beauty, adventure, and promise of space exploration.

In 2019, under the leadership of Bill Nye and our board of directors, the Society adopted a visionary five-year strategic framework called Space for Everyone. This framework embodies our commitment to you, the explorer. In it, we outlined our priorities for organizational decision-making through 2024 and beyond. As our plan has unfolded, we have added more opportunities to participate in the great adventure of space — programs you will recognize, like the quickly growing Planetary Academy for kids and our new wildly successful online member community.

Supported by a generous $9 million lead gift from fellow member Taner Halıcıoglu, the Society has been able to achieve growth not seen since our founding decade. If you were with us for our Planetfest ’21 virtual fundraising gala, you will remember that’s where we first shared the news of Taner’s amazing commitment. And now, as of December 2023, we are excited to announce that we have raised an astounding $32 million toward our $40 million goal! With a deadline of Dec. 31, 2024, we are now poised — with your help — to complete and even exceed our campaign goal.

Day by day, we reach more and more of the world’s citizens with our message that space is for everyone. We celebrate Taner’s momentous gift, but it will not be any one individual who makes these things happen. It will be a society of people — members like you — who believe that space exploration is a worthy use of our intellect and treasure. By harnessing our collective passion, we can change the course of history. With a transformative goal of $40 million, the Beyond the Horizon campaign will grow and strengthen the Society and fuel our efforts to explore worlds, search for life, and defend Earth. And with your support, we will help everyone come to know the Cosmos and our place within it.

This spring, the Society will launch a special appeal to members for support of the Beyond the Horizon campaign. If you have any questions, please reach out to Chief Development Officer Richard Chute at [email protected].

Richard Chute,
Chief Development Officer


Beyond the Horizon embodies three calls to action for the Society and its members.

A hard-to-pronounce meteor shower

In the sky

Super-bright Venus is in the pre-dawn east, dropping lower to the horizon as the weeks pass. Reddish Mars is very low in the pre-dawn east in February, getting higher in March. Venus and the much dimmer Mars are less than 1 degree apart Feb. 21-23 but may be hard to view, being very low to the eastern horizon. Very bright Jupiter is high in the evening sky, moving to the west as the weeks pass. Yellowish Saturn is in the early evening west dropping toward the horizon as days pass, becoming hard to see by February. Mercury is low in the pre-dawn east below Venus in mid-January. Mercury is low in the evening twilight west below Jupiter in late March. The hard-to-pronounce (for me at least) Quadrantids meteor shower peaks the night of Jan. 3/4. The Quadrantids can be an above-average shower near its peak, with 20 meteors per hour from a dark site. A third-quarter Moon will rise around midnight and wash out some of the dimmer meteors this year. For more night sky tips, you can always check out

Farewell to Bennu

Farewell to Bennu Artwork by Planetary Society member Danielle Rose.Image: Danielle Rose

OSIRIS-REx finished its journey to bring an asteroid sample back to Earth this year in September after being in space for seven years. The whole time it was out there, it remained on the minds of space enthusiasts around the world, including Planetary Society member Danielle Rose. She made this watercolor painting to capture the moment that OSIRIS-REx departed the asteroid it had been sent to study. With OSIRIS-REx now on its way to another asteroid target, it will no doubt continue to inspire wonder and imagination in the minds of those who love space.
