We also uncovered other documents about the #WowSignal that had never been published before — they describe its strange properties and the efforts by its discoverers to explain it. 🙂

While we were on our trip, we found out something interesting — the first description of the #WowSignal was written in October 1977, just two months after it was detected. Yet, it didn’t reach the public until the summer of 1979. 🤔

The phosphine molecule, PH3, has been proposed as a biosignature in rocky planets. In @science.org, Burgasser et al. report phosphine in a brown dwarf atmosphere. "We therefore caution against the use of phosphine as a biosignature". #stellarastro #exoplanet ☄️

Observation of undepleted phosphine in the atmosphere of a low-temperature brown dwarf

The atmospheres of low-temperature brown dwarfs and gas giant planets are expected to contain the phosphine molecule, PH3. However, previous observations have shown much lower abundances of this molec...

I visited Bob Dixon, who served as director of the Big Ear radio telescope from 1973 to 1998. He was the driving force behind the Big Ear's SETI project that captured the legendary Wow! Signal. #AreciboWow #SETI #Astronomy #Astrophysics #WowSignal

This week (!) is the 30th anniversary of the announcement of 51 Pegasi b, the first exoplanet found orbiting a star like our Sun - since then, we've found over 6,000!

To celebrate, @alexwitze.bsky.social and @nature.com collected some astronomers' favourite planets:

These alien planets are astronomers’ favourites: here’s why

Space scientists look back on 30 years of exoplanet discoveries — from rows of massive ‘super-Earths‘ to worlds with perfectly synchronized orbits.

🔭🧪🪐Fabulous article in BBC today marking the 30th anniversary of 51 Peg b, discussing also the hunt for Earth-like #exoplanets with the Terra Hunting Experiment @terrahunting.bsky.social — can’t believe we’re so close to starting this incredible survey (later this year)!

Indeed, the telescope’s data in paper were dispersed and saved by various individuals, and we are in the process of visiting each one. At this stage, approximately 20 to 30% of the data have been digitized.

I don’t see any real connection between the Wow! Signal and 3I/Atlas, other than the fact that they both happen to come from a direction near the galactic center, where the sky is crowded with potential sources that could explain them separately. 😕

I gave a talk about my paper last month with this as the title slide. Can you tell I recently watched #Murderbot? 🔭 #Exoplanets

A heavily modified version of a screenshot of the show-within-a-show "The Rise & Fall of Sanctuary Moon" in the Apple TV+ series Murderbot. The title now reads "The Rise & Fall of Sub-Neptune" to reflect a recent paper by Kevin Hardegree-Ullman in which the population of sub-Neptune exoplanets experiences a rise toward cool stars, then a fall when you reach stars cooler than about 3750 Kelvin.
