Almost fifty years after it was detected, the Wow! Signal continues to tantalize and defy explanation. […] In 2020, interest in this candidate [extra-terrestrial intelligence] signal was revitalized when Cabellaro identified a Sun-like star in the vicinity of the sky where the Wow! Signal was detected. If the analysis is correct, this famous signal may have come from a Sun-like star located 1,800 light-years away.

More amazing is that actual progress continues to be made towards understanding the original signal’s origin. Fifty years ago, the area of the sky was known to contain a bunch of stars. Today? We know which of them have planets. …and which of those stars have a planet in the so-called habitable zone. The article is both a good introduction to the famous (among astronomy enthusiasts) signal and a good story about continued research.
And just ignore the article’s click–bait title, which comes from a tangential discussion about whether we should only listen for extraterrestrial intelligence or actually try to contact ET.
The annotated version of the visualization (shown above) highlights the GEOS FP model’s output for aerosols on August 23rd, 2018. On that day, wildfires caused huge plumes of smoke to drift over North America and Africa, three tropical cyclones took place in the Pacific Ocean, and high winds over the Sahara caused wind-borne dust particles to fill the sky. All of these produced aerosols which are represented in the visual by different colors.~ Matt Williams from, https://www.universetoday.com/139836/look-at-all-the-aerosols-pushed-into-the-atmosphere-from-fires-volcanoes-and-pollution-even-sea-salt-thrown-into-the-air-from-hurricanes/
I’m not sure if I’m more impressed by the beautiful composite photo and the science that went into it, or if I now just want to never inhale again.
This means that STEVE is not likely to be caused by the same mechanism as an aurora, and is therefore an entirely new type of optical phenomenon – which the team refer to as “skyglow”.~ Matt Williams from, https://www.universetoday.com/139809/that-new-kind-of-aurora-called-steve-turns-out-it-isnt-an-aurora-at-all/
Aside: “Steve” started as in-joke reference by some dedicated Aurora photographers. It was later backronymed.
I particular love this type of discovery. Looking at the shape of the visual phenomenon—it’s a straight-ish thin streak—I bet this is realated to certain types of mythologies and stories…
