Starry Time Podcast

BoP went out on an adventure today and saw some cows!

Our #CreatureCorner episode on Cows (in honor of #Io) was definitely one my favorites -- check it out here: starrytimepodcast.podbean.com/

"What has happened is that the British government announced plans to cede control of the Chagos Islands, which is a territory in the British Indian Ocean that the British government has controlled since 1814. Should that happen, the British Indian Ocean Territory could wind up no longer existing, and the two-letter country code, IO, would cease to exist."

Woah! That's huge!

The New Stack · What Is the Future of the .io Domain?As per the regulations, ICANN should discontinue the .io domain if the British Indian Ocean Territory ceases to exist. Or will it change its policy so that thousands of websites (including ours) won't lose their domain names?

Here is a gorgeous image of Io taken by the NASA Juno spacecraft on Dec 30, 2023 from a distance of 4,262 km.

I added approx. latitude and longitude info and the names of a few prominent volcanic depressions known as Paterae. Juno's image of Io covers the northern hemisphere with the area from longitude 0° to 90° basking in the Sun's rays.

Please take a look at fosstodon.org/@AkaSci/11167569 for some more info on Io.

No evidence of magma ocean on #Io based on Juno/JIRAM data: arxiv.org/abs/2412.04321 -> "A recent paper [...] used infrared images of Io acquired by the Juno/JIRAM instrument to derive a latitudinal dependence of the spectral radiance and conclude that such latitudinal dependence is consistent with a magma ocean model. We challenge their conclusions, and we draw attention to some potential issues with their analysis."

arXiv.orgNo evidence of magma ocean on Io based on Juno/JIRAM dataA recent paper (ref. 1) used infrared images of Io acquired by the Juno/JIRAM instrument to derive a latitudinal dependence of the spectral radiance and conclude that such latitudinal dependence is consistent with a magma ocean model. We challenge their conclusions, and we draw attention to some potential issues with their analysis. In this letter, we will use three arguments to show that: (1) the (ref. 1) paper uses saturated data; (2) the M-filter of the JIRAM imager is only a weak and incomplete proxy for the total power output; and finally (3) even assuming that the radiance was correctly estimated, the latitudinal dependence of the 4.8-$μ$m spectral radiance is not statistically significant. These facts, taken together, demonstrate that the results presented in (ref. 1) are not sufficient to confirm consistency with a magma ocean model on Io.
