NEW: On Oct 20, Japan will launch its most audacious space mission. It’s hoping to fly to Mars, land twice (!) on Phobos (“fear”), steal pieces of that alien moon, and bring ‘em home. That’s right: to pull of this heist, Japan must confront fear itself. @science.org www.science.org/content/arti...

Like many scientists, I’ve been mulling over the impact of LLMs on our fields. I’ve not yet seen it articulated, but I think there is a largely unspoken “invisible labor underclass” framework at play.

A closer view of Christchurch’s new tsunami blue zone ⬇️

The black line on the right is the coastline. West of that covered in blue is the tsunami zone.

Next to the rivers are blue zones quite a long way inland, too.Blue evacuation zone: Long or strong, get gone

This is an area that is most likely to be affected by a tsunami.

You should leave this zone immediately if:

    You experience a long or strong earthquake
    You see sudden sea-level changes or hear unusual noises coming from the sea
    You receive an official warning from Civil Defence Emergency Management

An official warning will most likely be issued through an emergency mobile alert to your phone. If there is an announcement to evacuate the blue zone, follow the instructions immediately. Stay out of this zone until you are told by an official source that it’s safe to go back.

How rare are neutrino interactions? A neutrino (of the type emitted by the Sun) could go through a light year of lead with only a small chance of interacting. They pass through the Earth, and each of us, constantly, without anyone noticing. 100 trillion neutrinos go through you every second.

Great to see in this bumper review of the LMC & SMC ditch the pointlessly colonial language that we have for the Milky Way's two nearest neighbours. arxiv.org/abs/2609.38277 Magellan had *nothing* to do with discovering them, and they were known to indigenous communities for millennia. 🔭☄️
1.1 Historical context: the cranes of the southern night sky

The two nearest star forming galaxies to the Milky Way are readily observable to the naked eye in the southern hemisphere. Consequently, these two galaxies have been known to humans, since there have been humans in those regions of the planet. Just like today, the origin and purpose/meaning behind their presence have been the subject of discussion and conjecture, as reflected in the mythology of most civilizations in the Southern Hemisphere. For example, the Mapuche people of Chile referred to these objects as “water ponds” (Rüganko or Menoko). The Clouds also feature in the oral histories of most Aboriginal groups in Australia. For example, in the Lower Murray they are known as Prolggi, which has been translated as “Cranes”. 

The earliest written records of the Clouds are possibly traced to the work of Persian astronomer Abd-al-Rahman al-Sufi (around 964 AD) in his treatise Kit¯ab suwar al-kaw¯akib (“The Book of Fixed Stars”). In western astronomy, these galaxies have been known collectively as the Magellanic Clouds, and individually as the Large Magellanic Cloud (LMC), for the larger of the two, and the Small Magellanic Cloud (SMC), for the smaller. The term “Magellanic” for the Large and Small Cloud was not coined by Magellan himself or his chronicler, and Magellan did not directly refer to the LMC and SMC themselves in his writings (Dennefeld 2020).

In this review, we will refer to these two galaxies collectively as “the Clouds” and separately as the LMC and SMC. As a field, Astronomy must adopt naming conventions thoughtfully and be ready to modify historical precedent (de los Reyes M 2023). As with the story of our understanding of the dynamics of the Clouds themselves, conventional wisdom cannot dictate modern astrophysical discourse. If we wish to advance our physical understanding of the universe, we must build an inclusive community that can support and sustain a diversity of scholars who will…
