Hi #exoplanets folks, I’m attending the Expanding Horizons conference @eso.org this week (thinking about the facility post-ELT… terrifying, I know 😅). One thing that came up is that relatively few early-career astronomers submitted (co-authored) white papers for the process. next.eso.org 1/3

We've discovered another long period transient with ASKAP! Source #15 in this small but growing population. It repeats every 36 minutes, but despite many observations (see plot) we're not sure what it is. New paper by Joshua Pritchard: doi.org/10.1017/pasa... #radioastro

There's some super neat radio astronomy work being done in Canada, complementing CHIME. This is CHORD: Canadian Hydrogen Observatory and Radio-transient Detector. 512 x 6m dishes with two outlier stations (64 dishes each). arxiv.org/abs/2607.09374 #RadioAstronomy 📡🔭

I am fully supportive of the case made by astronomers that this will harm the night sky. However, I think we will have more success if we fold in the cases from experts in the fields of biodiversity, population planning, and Indigenous communities to fight this. Wider impacts = better case IMO.

First detection of reflected light of an exoplanet at high spectral resolution? Borsa+ arxiv.org/abs/2606.30793 Would be cool! I don't really understand what their methods were though (not a problem for the reviewer, apparently). I hope there will be more explanation/replication. 🧪🔭 #exoplanets

Most of the world Wi-Fi usage operates around the 2.4 GHz band (allocated spectrum). That means our telescopes have to cut that portion of the band out when doing #RadioAstronomy Tommy from our team has tested some mitigation methods and found we can use 90% of this band! arxiv.org/abs/2605.30761

Statistically, the lack of clear evidence for extraterrestrial life so far admits many possible explanations, which is the essence of the Fermi Paradox. But only one of them can be the correct answer? Figure that out. 🤔 #UFOs #UAPs #DisclosureDay

Statistically, decades of observations of the universe might include every kind of detectable phenomenon. Yet everything we’ve detected so far appears natural, and nothing is clearly the product of an extraterrestrial civilization. Figure that out. 🤔 #UFOs #UPAs #DisclosureDay

Statistically, the Galaxy might contain both passive civilizations and aggressive, expansionist ones. Yet after billions of years of opportunity, none have colonized Earth. Figure that out. 🤔 #UFOs #UPAs #DisclosureDay

Statistically, evidence of any aerial object should include both nearby, easily identified examples and distant, ambiguous ones. Airplanes, balloons, birds, etc., do. Alien spacecraft, however, seem to exist only at blurry distances. Figure that out. 🤔 #UFOs #UAPs #DisclosureDay
