In 1994, Carl Sagan urged that the Wow! Signal be revisited, re-analyzed, compared with previous data, and formally published. Yet, for 30 years, this call went unanswered, until our team finally took up the task. #AreciboWow #Astrophysics

Uranus is warmer than we thought. New computer modeling techniques revealed that Uranus generates internal heat. This is similar to our solar system’s other gas giants, like Jupiter or Neptune. go.nasa.gov/44HzIKx

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO observatories. caltech.edu/about/news/lig…

New paper! Allow me to introduce TARS = Torqued Accelerator using Radiation from the Sun. TARS (yes inspired by Interstellar!) is a rotating light sail that's capable of launching chip sats into interstellar space using only radiation from the Sun, so let's dive into how it works

“Right after Lyne owned up to his team’s mistake, then-Arecibo Observatory astronomer Aleksander Wolszczan took the stage. He and his co-author Dale Frail, of the National Radio Astronomy Observatory, had, in fact, glimpsed not one but two bona fide exoplanets—“

Just to reiterate for the curious: While there's *nothing wrong* with thinking about whether some interstellar objects could be alien technology, 3I/ATLAS has had its coma clearly detected since July 3. It's very clearly, *unambiguously*, a comet. sites.psu.edu/astrowright/20…

Astronomers are filling in the details of an intriguing five-planet system around a nearby red dwarf star. L 98-59 has a likely lava-volcano world, ocean world, sub-Earth, and now a super-Earth in its (potential) habitable zone. nouvelles.umontreal.ca/en/article/202…

August 15 marks the 48th anniversary of the Wow! Signal, and our #AreciboWow team will be presenting that day a paper featuring major revisions and newly uncovered properties of this mysterious event. 😉 #astrophysics #radioastronomy #seti

Avi has a new missive out about 3I/ATLAS and it's about what you'd expect. He cites a paper finding 3I/ATLAS has a coma but sometimes no obvious tail before July 18 as validating his earlier arguments, when it fact it proves he was wrong all along. sites.psu.edu/astrowright/20…

Last week, The Planetary Society hosted a briefing on the Habitable Worlds Observatory in Washington DC. Attendees got to ask questions directly to top experts in astrophysics and astrobiology about why HWO will be a game-changer in the search for life. We’re working every day
