On this Juneteenth, check out the June issue of Sky & Telescope for my article, 'Freedom's Beacon,' on the astronomy of the Underground Railroad. There are misconceptions about how this network operated, and the night sky played a pivotal role in freedom's movement. #Juneteenth #astronomy #history

Post D-Day anniversary, here is my Veteran take on what makes the move Pressure so compelling ... #history #DDay #WWII #skystorians #veterans #metoc

#OTD in 1863, Harriet Tubman, aboard the USS John Adams, presided over the successful #Combahee River Raid, liberating 756 enslaved people. The Moon played a role as well; read about it in my article Freedom's Beacon in the June issue of Sky & Telescope. #history #freedom #skystorians #astronomy

With Spielberg’s film Disclosure Day coming, there'll be lots of UFO questions. I put together a new guide to resources on what skeptics know about UFO claims & cases, including Roswell & recent military photos, at: bit.ly/ufoskeptic #astroed #UFO #UAP #skeptics #astronomy #scienceeducation #UFOs

Remembering Captain Kermit O. Evans on this Memorial Day weekend.

I've created a list of Ford's Theatre attendees on the night Lincoln was assassinated: joebarryauthor.com/fords-theatre. It's been awesome hearing from descendants, including John Finnegan of the 98th NY Volunteer Infantry. Would you mess with him? Not me. #history #skystorians #civilwar 💙📚✍🏻

Today is the birthday for both Lincoln's assassin, and the formerly enslaved Henry Bibb, who found freedom, toured with Frederick Douglass, and established the first Black newspaper in Canada. #freedom #history #NorthStar #UndergroundRailroad #skystorians #Kentucky #Canada #Trimble

Elated to have my article on the #astronomy of the Underground Railroad appear in the June issue of @skyandtelescope.bsky.social! There are some misconceptions on how the network operated, and astronomy played a key role in freedom's movement. Look for it next month. #history #skystorians #freedom

#OTD Lincoln's assassin was finally captured and killed after 12 days on the run. If you're into this part of American history, check out my list of Ford's Theatre eyewitnesses here: joebarryauthor.com/fords-theatre Contributions welcome! #history #skystorians

An awesome time with @assassinationtours.bsky.social this weekend! If you're interested in this key moment in our history, book now for the fall tours!

Absolutely fantastic time yesterday on the Lincoln Assassination Tours bus ride!

Highly recommend anyone interested in this event attend! #history #skystorians #Lincoln

Today is the anniversary of the Lincoln assassination. Contrary to popular belief, the audience didn't just sit down in response. In fact, prominent lawyer Joseph B. Stewart chased after Booth.

Honored to appear on Dave Taylor's LincolnConspirators.com on the 161st anniversary of the assassination: Who Attended Ford's Theatre? by Joe Barry lincolnconspirators.com/2026/04/14/w... #history #Lincoln #assassination #booth

I hear tell that Expedition Files on Discovery will be rehashing the “Booth” mummy story tonight. I don’t have cable so I won’t be watching. But for the sake of anyone who watches it and starts wondering if John Wilkes Booth might have escaped justice in 1865, the answer is a resounding no. He dead.

It's been a bad week for a lot of people, but also a bad week for Flat Earthers and Moon Landing Truthers. #science #astronomy #conspiracy

There is a view, correct in its own right, about the Earth being a pale blue dot, insignificant compared to the trillions of other planets and stars in the galaxy and beyond. But we are not insignificant. As astronaut Victor Glover notes, we are an oasis in a desert, among so many lifeless worlds.

In 2011, I ate dinner in Nairobi with friends and a waitress asked if we wanted to sign up for local discounts. I said “sure.” Ever since, I have received occasional spam for “opportunities” in Kenya and Uganda. It’s the one piece of spam that makes me smile and think about a wonderful trip.

Sorry it took me so long to grade your August 20 assignment, Avi Loeb. Are you sure you're ready for a class on comets? You might need to learn about things like bow shocks and chemistry.

Still waiting for a silly explanation from a certain Harvard astronomer on why ethanol from interstellar comet 3I/ATLAS is somehow explained by nefarious aliens. #psuedoscience #nonsense 👽🛸

Happy International Women's Day! Perfect time for me to (re)share our white paper on increasing the retention of women in professional astrophysics (really full of suggestions that broaden participation in academic science in general). arxiv.org/abs/2512.24465 🧪🔭☄️👩‍🔬

Have you ever looked up and dedicated a star to somebody? I wrote this piece in honor of my stepmother, Donna, who passed away on this day 18 years ago: joebarryauthor.com/s/A-Star-for... #astronomy #stars

Did you see the lunar eclipse this morning? Eclipses happen every year somewhere on Earth, and are therefore not reported as rare. "Planetary alignments" are not rare either, so why are they reported as such? Read on ... #astronomy #astrology #science #planets

Awesome content from my friend Dave Taylor: Civil War Breakfast Club Podcast Appearance lincolnassassinationtours.com/2026/03/01/c... #history #skystorians

I had the pleasure of seeing Dr. Diana Hannikainen, Editor in Chief of @skyandtelescope.bsky.social at the Winter Star Party. She gave an excellent talk of her journey as a scientist and editor, and I was happy to show her several objects through my telescope later that evening. #astronomy

The Winter Star Party in the Florida Keys last week was a great time. Every night was clear, the talks were interesting, and the people friendly! Highly recommended! ✨ 🔭 🌴 💙 #astronomy #telescope #astrophotography #floridakeys

🗃️ Listening to the audiobook of @desiarnazbook.bsky.social by Todd Purdum, I learned that Desi Arnaz had a newspaper announcing Abraham Lincoln’s death in his Desilu office. Lucy & Desi also appeared in the same gameshow as the last witness to Lincoln’s death: youtu.be/do0bzKxZDM4?... #skystorians

When the fugitive Lincoln assassination conspirator John Surratt was returned to the U.S. to face trial in 1867, he came face-to-face with members of the Kanza/Kaw tribe. For Native American Heritage Month, we share the story of The Kaw and the Last Lincoln Conspirator: youtu.be/tkeCG1AExos?...
