Here are some recent stories of interest.

—Gizmodo.com: “New NASA Official Took Her Oath of Office on Carl Sagan’s ‘Pale Blue Dot’”

When Dr. Makenzie Lystrup was sworn in as the new director of NASA’s Goddard Space Flight Center last week, she didn’t take her oath of office on the Bible or the U.S. Constitution, but rather on a tome revered by space enthusiasts everywhere: Carl Sagan’s Pale Blue Dot. The book, published in 1994, is named after an iconic image of Earth, snapped by the Voyager I probe, that depicts the planet as a small speck smothered by the emptiness of space. That photo inspired astronomer Carl Sagan to write: “Look again at that dot. That’s here. That’s home. That’s us.” For many, the book serves as a reminder of humanity’s place in the universe and the need to preserve our home planet, which makes it similar to holy scripture for a newly appointed NASA director.

—Time: “In Five Years, China Will Start Building a Lunar Base With Bricks Made From Moon Soil“

China plans to start building a lunar base in about five years, kicking off with bricks made of moon soil, according to scientists with ties to the project, the South China Morning Post reported. Ding Lieyun, a top scientist at Huazhong University of Science and Technology, told local media that the first brick would be made from moon soil during the Chang’e 8 mission around 2028.

—AFAR: “NASA Teams With NYC Museum on New Immersive Outer Space Exhibit“

With its blazing city lights, New York is one of the worst places to go stargazing. But space aficionados will want to visit lower Manhattan this spring—dark skies or not—thanks to a new digital art exhibit created with participation from NASA and CNES (the French space agency) that opened April 7 at Hall des Lumières, the city’s first permanent immersive art center. An earlier iteration of this show premiered at Hall des Lumières’ sister museum in Paris, Atelier des Lumières, in 2021. Destination Cosmos: The Immersive Space Experiencewill run for eight weeks through June 4, 2023, at Hall des Lumières, which opened in 2022 in the former Emigrant Savings Bank across from City Hall.

Podcast: Discussing Science Fiction and Astronomy with Andy Weir & Rob Manning

If you have not yet tapped into The Planetary Society’s podcast Planetary Radio, then now is the time to do so. Host Mat Kaplan and his guests had a great time on the recent podcast, One Last Blast: Author of ‘The Martian’ Andy Weir with JPL Chief Engineer Rob Manning.

Both Andy Weir (author of The Martian, Artemis, and Project Hail Mary) and Rob Manning (Chief Engineer at the Jet Propulsion Laboratory) were shooting the you-know-what as they chatted about science fiction books they read as teenagers, the role of real science in fictional tales, astronomical conspiracy theories, and mankind’s need to expand into the unknown.

It was interesting to hear Andy Weir talk about curiosity being humanity’s survival mechanism. He pointed out that curiosity has allowed humanity to survive disasters here on Earth because we were all spread out rather than clustered on one flood plain. The same applies to expansion beyond the Earth.

Check it out for yourself. You may want to check out some of the earlier podcasts as well, such as:

If you are looking for another gift idea for the holidays, maybe you should consider one of the many popular astronomy books. Here are the 10 most popular from Goodreads:

It’s great to see that Carl Sagan is still educating the public so many years after his death. As with the Voyager spacecraft, his words and contributions are traveling far and wide.

A Day in Astronomy: The Birth of Carl Sagan

On this day in 1934, scientist and communicator Carl Edward Sagan was born in Brooklyn, NY. He was to become a great communicator of all things related to astronomy. He has played a key role over the years introducing millions to our place in the universe through his books, television series, speeches, and scientific work. His television series Cosmos was a milestone in educational television, bringing the stars and planets into everyone’s living room, while his books (Contact, Pale Blue Dot, The Dragons of Eden) continue to encourage the next generation of astronomers.

Dr. Sagan has a long resume, but I am most fascinated with his work to communicate with extraterrestrial life. He was a strong supporter of the Search for Extra-Terrestrial Intelligence (SETI) and worked with NASA to ensure our spacecraft were equipped with a record of human activity to educate other planetary civilizations, including the gold records placed on the Pioneer 10 and 11 space probes as well as the two Voyager space probes.

Years ago, the Smithsonian magazine had a good summary of Dr. Sagan’s life in the article “Why Carl Sagan is Truly Irreplaceable.” I recommend the article as a good way to get to know the man, though delving into his books is even better.

Extra: Carl Sagan was also the founder and first president of the Planetary Society. Visit this Planetary Society site, Ann Druyan wishes you a happy Sagan Day, for more on Dr. Sagan’s work.

Arecibo Observatory Gone Forever

If you were hoping that the Arecibo Observatory in Puerto Rico would have a second life, it may be time to say goodbye. Efforts to rebuild the radio telescope since it collapsed in 2020 have ended. Nature reports that the US National Science Foundation (NSF) has given up on the idea of rebuilding the telescope and instead plans to establish an educational center at the site.

You may have memories from the 1997 film Contact where Matthew McConaughey and Jodie Foster enjoyed some private time at the Observatory. Her character Dr. Ellie Arroway was working at the Observatory as part of the Search for Extraterrestrial Intelligence works (SETI) program. In fact, the SETI connection is true. You can see a SETI tribute to the telescope here.

Of course, scientists will remember almost 60 years of work with the radio telescope. While it was initially built for military purposes, it was soon transformed into a scientific site and served as the largest radio telescope on the planet for some time. As far as scientific accomplishments, here are a few of them from the NSF:

1967: Arecibo discovered that the rotation rate of Mercury is 59 days, not the previously estimated 88 days.
1981: Arecibo produced the first radar maps of the surface of Venus.
1992: Arecibo discovered the first ever exoplanet: In subsequent observations, an entire planetary system was found around the pulsar PSR 1257+12.
2008: Astronomers use Arecibo to detect for the first time, methanimine and hydrogen cyanide molecules — two organic molecules that are key ingredients in forming amino acids — in a galaxy 250 million light-years away.

So many new telescopes have come online in the past 60 years that some will say we will be fine with an educational center. This is true, but it is also worth remembering each of the telescopes along the way that helped us to understand this awesome universe of ours.
