It is still painful to see the ruins of the big dish.

Five years after the collapse of the Arecibo Telescope, a radio telescope is back online. The signal is back. #AreciboWow https://phl.upr.edu/wow/outreach #RadioAstronomy #Outreach

On August 15, we celebrate 48 years since the Wow! Signal. #AreciboWow

El PHL está buscando estudiantes subgraduados para participar en el proyecto Arecibo Wow! durante este verano y el próximo semestre. https://phl.upr.edu/wow/projects #AreciboWow #PHL @CienciaPR @adamonzon @upr_oficial @upra_oficial

Wow@Home: Bringing a radio telescope to your home is now as easy and fun as setting up satellite TV — and it’s even more affordable! #RadioAstronomy #Astrophysics #RFI #Technosignatures #SETI #AreciboWow #WowSignal https://phl.upr.edu/wow/outreach

It's remarkable that Ohio's Big Ear radio telescope, which famously detected the Wow! Signal, was operated for over 20 years entirely by volunteers driven by curiosity and a passion for the search for extraterrestrial life in the universe. 😌 #AreciboWow

Our #AreciboWow! project is conducting the most in-depth analysis of the Wow! Signal using results from the world’s longest-running SETI initiative. Excited to welcome @hsocasnavarro & @david_kipping to the team! 📡🔭✨ #Astronomy #SETI

This is a brief account of the day the Wow! Signal was detected, including some lesser-known details, with more to come. #RadioAstronomy #Astrobiology #SETI #WowSignal #AreciboWow https://phl.upr.edu/wow/story

Milestone reached! We've finally determined the intensity of the Wow! Signal—one of its long-standing mysteries. Previous estimates were 54 Jy or 212 Jy. This new finding is just one of the key insights we’ll present in our upcoming paper, #AreciboWow II. #Astronomy #RadioAstronomy #SETI

The revised Wow! Signal page now includes recalculated coordinates in both equatorial and galactic terms. The central frequency replaces the previous local oscillator frequency, and objects along with the continuum (CNT) are added. #AreciboWow #Astronomy #SETI

This might be the earliest known hand-drawn visual depiction of the Wow! Signal, dating from approximately 1977 to 1983. The creator is unidentified, but likely one of the astronomers involved in the Ohio SETI project. #AreciboWow

The “Big Ear” telescope operated from 1963 to 1998. Unfortunately, its data was never properly saved for future astronomers. However, three dedicated volunteers preserved most of it, and we are now collaborating with them to complete the task. #AreciboWow

We’re also exploring the history of the Wow! Signal and the “Big Ear” telescope. The first newspaper mention of the signal (before it was named) was in the Dayton Daily News on January 5, 1979. That's 16 months after its detection. 🙂 #AreciboWow

This plot includes all the data collected from 1:20 PM EST on Monday, August 15, 1977, through the following day—the day the Wow! Signal was detected. We are currently analyzing this rich, long-overlooked dataset. We now have significantly more knowledge. 😃 #AreciboWow

Two hours of never-before-seen data surrounding the time of the Wow! Signal—far more than the original 16-minute printout. #AreciboWow

1420 MHz is the best frequency to spam alien astronomers. 😄 #seti #technosignatures #wowsignal #arecibowow

We will analyze the code used by the Ohio SETI project in 1977 that detected the Wow! Signal. Much of it should function on contemporary computers, and we may even run everything in an IBM 1130 emulator, similar to how it was done almost 50 years ago. #AreciboWow #Retrocomputing

This is the last data line the "Big Ear" telescope recorded on printouts on April 25, 1984. I was with family near Columbus, Ohio, a couple of weeks after that, and I missed the opportunity to visit this telescope, which I didn't know existed then. 😕 #AreciboWow #WowSignal

We now have access to the original Wow! Signal computer code and are embarking on the process of transcribing it. This critical step will allow us to better understand the methodologies used to analyze the signal. #AreciboWow #WowSignal

2027 marks the 50th anniversary of the legendary Wow! Signal—a powerful symbol of humanity's quest for extraterrestrial life and the endless mysteries of the cosmos. By then, we may have unlocked many of its mysteries—but imagine what more we could discover!" 😃 #AreciboWow

A Piece of Cosmic History for My Office Wall! This stunning poster features the final, never-published sky survey by the legendary 'Big Ear' radio telescope—the instrument that detected the mysterious Wow! Signal in 1977. #AreciboWow

Our explanation of the Wow! Signal has been recognized as one of the top scientific stories of 2024 by Knowable Magazine. @knowablemag @AnnualReviews @PlanetaryHabLab @UPRA_Oficial @UPR_Oficial #AreciboWow https://knowablemagazine.org/content/article/society/2024/top-scientific-news-and-breakthroughs-of-2024

Consider supporting the #AreciboWow initiative, which involves searching for extraterrestrial communications using the archival data from the Arecibo Observatory. Remember, #GivingTuesday is coming up next week. https://phl.upr.edu/wow https://phl.upr.edu/support

The second version of our #AreciboWow paper is now available here and soon in ArXIv. It has many more details and interesting facts, thanks to the astronomy community's help. https://phl.upr.edu/wow

Here is a draft of our galactic map of the stars with potentially habitable worlds. It shows regions of interest, such as the Arecibo Message and the Wow! Signal. What else should I add or change? The final versions will be available on August 15. #AreciboWow

The 47th Anniversary of the Wow! Signal is August 15. https://phl.upr.edu/wow #AreciboWow
