New article out from Astro Society staff in the Astronomical League's Reflector magazine! Our Senior Astronomy Education Specialist, Theresa J. Summer, writes about NASA's International Observe the Moon Night, this year taking place on September 19, in their new June 2026 issue 🌔🔭🧪

“It's sort of like going to a concert,” Troche explains. “Everybody's there to see the band play—everyone's excited. It's the same vibe.” I was happy to speak with Amy Brecount White at #NationalGeographic about #stargazing this summer! www.nationalgeographic.com/travel/artic...

M57, the #RingNebula, is approximately 2,000 light years away from Earth in the constellation Lyra. It's an 8.8 magnitude planetary nebula, making it challenging to see with your eyes from light polluted skies, but easy work for this scope. Image time: 3 minutes

Happy Pride from the Astro Society team! 🎉🌈 NASA created this image using their space photography images (all of which are public domain, so cool!) to create the colors of the modern LGBT+, intersectional pride flag. 💫 Space is for everyone and we celebrate our beautiful, diverse communities.

TODAY!! At 6p PT/9pm ET - join us on YouTube and hear about Artemis II lunar science: www.youtube.com/watch?v=ThVg...

New logo, new era! We are now The Astro Society ✨ Our publications and awards will remain with our legacy name, the Astronomical Society of the Pacific. All new content, our upcoming AstroBeat video series and podcast, plus our expanded presence at events will be as The Astro Society. Welcome!

Throwback post: This week’s image is of the globular cluster Liller 1! Despite its proximity to the Milky Way’s galactic bulge, Gemini captured this stunning image using the GeMS adaptive optics system on Gemini South. Check out the 🧵! #Astronomy

Friends, it has been an honor and a privilege experiencing Artemis II with you all! If you want to stay involved in NASA Science programs, here are some things you can do 🧵

How the Artemis crew will splash down on Earth. 🔭 🧪 www.bbc.co.uk/news/videos/...

Our annual Awards submissions deadline is extended through next Wednesday, April 15 - get those nominations in! 💫 Every year, we recognize individual achievements in astronomy research, technology, education, & public outreach. Past recipients include luminaries such as Edwin Hubble, Vera Rubin...

It seems fitting, as the Artemis II mission continues its journey, that April is Global Astronomy Month! 🔭 We're watching STEAM education in action, something we are committed to 365 days a year. We offer workshops, courses, & hands-on educational activities for every age and learning level...

24 minutes til Artemis surpasses Apollo's record!!

Friends: if you were an astronaut about to orbit the Moon on #ArtemisII, what would you want your wake up song to be? I've gotta go with Tank! youtu.be/UFFa0QoHWvE?...

#ArtemisII has entered the lunar sphere of influence!! Less than 40k miles left. LET'S GOOOOO 🚀🌕🚀

Real talk: what are we all wearing for Moon-Day tomorrow?? I've got my pins and patch ready. #ArtemisII

Two years ago, I had the opportunity to meet Reid Wiseman before we participated in the NASA total solar eclipse broadcast. I hope he and the #ArtemisII crew get to experience another solar eclipse from the far side of the Moon this Monday!

The focus of NASA's #Artemis 2 mission is shifting from views of Earth to the main event - sending humans around the moon's far side for the first time in more than 50 years. And don't miss the Easter message from NASA astronaut Victor Glover: cosmiclog.com/2026/04/04/o... #Space

If you want to (potentially) spot #Artemis with a telescope, pull up Integrity's ephemeris with JPL's Horizons! You can calculate it by selecting Artemis II as the target body and entering your closest city and state ssd.jpl.nasa.gov/horizons/app... Happy spotting!

Here's an image I just took of the Artemis II mission showing the Orion spacecraft and the upper booster module (not sure which is which) taken when they were around 69,000 km from Earth aloing with an image of Earth from the spacecraft taken at the same time. Taken with my Unistellar telescope. 🔭 🚀

Want to follow the crew of Integrity during Artemis II? Visit NASA.gov/missions/artemis-ii/arow/ and follow the real-time flight! You can also visit NASA Eyes on the Solar System for a simulation of this, and all past nasa missions 🚀🌕

I'm overwhelmed with joy. Go #NASA. Go #Artemis II 🚀🌕

We are the oldest astronomical society in the United States, but we're not quite as old as the first photo ever taken of the moon. 🌔 This public-domain image is a daguerreotype by John W. Draper taken in 1840 from his rooftop observatory at New York University, and predates our founding by 49 years.

Artemis II is on track for an April 1 launch, so mark your calendar & join us at 2:30pm PT/5:30pm ET for a LIVE viewing party on our YouTube channel (at astrosocietypac). RSVP to our event on Facebook or add a reminder to your calendar app. 📅 👩🏻‍🚀🧑🏻‍🚀 Amy Imhoff, ASP's Director of Digital Brand...

Welcome, spring! 🌸 On Friday March 20, our team celebrated the Spring Equinox by observing sunset over the San Francisco Bay with a solar telescope, the Mayan Day Count Observer, Exploratorium, and local Mayan Yucatec Jarana Dance Group. Vivian White, our Director of Free Choice Learning...

Only 8 days left to submit excellent folks for our annual ASP Awards! Every year, we open our submission portal so YOU, our peers, can celebrate the people in your orbit who do amazing work in the areas of astronomy research, astro tech, education, and public outreach. This is your reminder that...

From NASA NASA’s Parker Solar Probe just did it again. ☀️ On March 11th, it completed its 27th close approach to the Sun, flying just 3.8 million miles from the solar surface at a blistering and record-matching 430,000 mph. New data drops March 18: go.nasa.gov/474BFBH

TFW the clocks move forward, and everyone is so happy, but you're losing an hour of stargazing. #DaylightSavings happens tomorrow at 2 AM, so make sure you reset your analog watches and the oven clock. We'll be back to standard time in November.

I need to go to Iceland this August for my total solar eclipse do-over. I'm willing to take a chance with the weather 🇮🇸

I tell people that if the government is covering up the existence of aliens, NASA is absolutely not involved, because astrobiologists can't keep a secret to save their lives

I'm about to crash out #TotalLunarEclipse #OvercastSkies

LOCK IN: on March 2-3, parts of North and South America, the North Pacific Ocean region, along with parts of Russia, Australia, Japan, etc. will experience a #TotalLunarEclipse! Here are your total eclipse times for time zones Eastern to Chamorro Standard Time (aka Guam):

The first crewed Moon landing since 1972 is now planned for Artemis IV in early 2028, possibly followed by Artemis V before the end of 2028: www.youtube.com/live/eCbQtyU...

We are counter-programming the State of the Union with a fundraising telethon featuring everyone’s favorite Bluesky posters doing short presentations and sketches on stuff they are passionate about. Will stream on YouTube starting at 8:30pm EST postersmadness.wordpress.com

This weekend, don't forget to check out a rare 6-planet alignment shortly after sunset on Saturday, February 28. Mercury, Venus, Jupiter, Saturn, Neptune, and Uranus will be visible from our vantage point here on Earth - although you will likely need a telescope for Uranus and Neptune. 🔭🌏 (1/2)

Happy s39th birthday to SN 1987A- the closest to us since the invention of the telescope! 🥳 Always a good excuse to share my cross stitch evolution over time in radio of SN1987A. Everything is to the correct scale etc bc cross stitch is the original pixel art. 🔭🧪 #sciart

bruh, the sidewalks JUST cleared 😫 #NYCBlizzard2026

I'm still so emotional 🥹 🇵🇷

this is my first time seeing aurora in my game 😭 #ACNH

If you've ever wondered what Hubble and Webb were observing at any time, there's an easy way to find out! 👀 Space Telescope Live can show you what the telescopes are looking at now and what the next planned observation will be, all in one space (pun intended 😁): https://spacetelescopelive.org/

Another sunny day, another session with the Heliostar ☀️🔭 iPhone 15 with the @skywatcherusa.bsky.social Heliostar 76mm Hα telescope. 10 second live video, then processed in Adobe Premiere. #sungazing #astronomy #astrocelltography

HUGE thank you to @skywatcherusa.bsky.social for this incredible telescope! The Heliostar 76mm Hydrogen Alpha Solar Telescope is gonna be the new go-to for all my solar observations this year, both in person and via livestream ☀️🔭 #astrocelltography #astronomy #AmateurAstronomy #HydrogenAlpha
