Today I stumbled upon the phrase "Eppur si muove" ("and yet it moves"), tenuously attributed to Galileo after being forced to recant his claims that the Earth moves around the Sun to avoid being punished by the church.

The impact and rhythm of the phrase really inspired me, so I wrote a poem about it.

I absolutely adore this one!

Tools for Thinking About Censorship

The Roman Inquisition in the 1500s was constantly complaining about its desperate lack of personnel (not enough Inquisitors, not enough censors to read books, not enough police) as it tried to keep up with the exponentially-growing flood of books enabled by the newfangled #PrintingPress. Why would such an organization waste hundreds of man-hours per copy on crossing out pages when they could have trivially burned the book and moved on?

Did the trial of #Galileo succeed or fail?

“Did the US government censor The #BlackPanther ?”

"The Inquistions didn't set out to silence #Galileo...it could have just assassinated him....Instead, the Inquisition persecuted Galileo, in a very high-profile manner

...The point of persecuting Galileo was to convince Descartes to self-censor... [and] "thousands of other major thinkers of the time wrote differently,...because they self-censored after the Galileo trial."

And this is exactly why the US so aggressively pursues #whistleblower like #Snowden and #Assange.

#Iris2: the architecture of the #European Internet constellation soon to be revealed. The European Commission is due to receive their proposal by February 14.

IRIS2 is set to become #Europe’s third satellite component, after the #Galileo (geopositioning) and #Copernicus (Earth observation) systems. Its main mission will be to guarantee the security of government telecommunications and public services while providing global Internet coverage.

Let's get ready for Juno's highlight of the year - an extremely close flyby of Jupiter's moon Io!

The NASA Juno spacecraft will make its 57th flyby of Jupiter (Perijove 57) on Sat Dec 30 around 7:39 a.m. ET (12:39 UTC).

A few hours earlier, around 3:36 a.m. ET (08:36 UTC), it will swing by the Galilean moon Io at a distance of 1,500 km. The record will still be held by the Galileo spacecraft which came within 200 km in 2000.

Here is the iconic image of a volcano eruption on Io captured by the Galileo spacecraft on June 28, 1997 from an altitude of ~600,000 km.
The plume on the left is over a caldera named Pillan Patera. The plume was also detected by the Hubble Space Telescope.
There is another plume named Prometheus over a volcano near the center of the image.

Let's hope Juno catches a volcano in its act on Io!

New data from JWST of Jupiter's moon Europa has identified the sub-surface ocean as the source of CO2 deposits in a region called Tara Regio.

Previous studies, including observations by the Galileo mission many years ago, had detected CO2 but could not rule out an asteroid origin for the CO2.

The 10x10 pixelated images show wavelengths measured by the NIRSpec instrument in 320 x 320 km cells covering Europa. The white pixels correspond to CO2.

Tara Regio is the yellowish area shown in these images of Europa’s surface taken by the NASA Galileo spacecraft in June 1997 from a distance of 1.25 million km.

In 2019, visible light spectroscopic observations by Hubble identified sodium chloride (common salt) in the yellow colored regions, including Tara Regio.

Although not conclusive, the NaCl is believed to originate from the sub-surface ocean.
