"Because the biosphere, as a living system, processes information in ways nonliving systems do not, information-theoretic approaches can capture aspects of coupled system dynamics that might otherwise remain invisible to purely physical or chemical models".
On the left, 24 amber colored debris disks are shown in six rows of four disks. They are ringed structures of various densities and inclinations. On the right, a column of blue disks matches the last column of amber ones, revealing the location of gas in the dusty structures.
#PPOD: This ALMA survey to Resolve exoKuiper belt Substructures (ARKS) gallery of faint debris disks reveals details about their shape: belts with multiple rings, wide smooth halos, sharp edges, and unexpected arcs and clumps, which hint at the presence of planets shaping these disks. 🧪 🔭

One of the reasons why I go so hard on science misinformation/disinformation, is that as a working scientist it is frustrating to see your research misreported to push an agenda.
For example, consider this piece of right-wing propaganda from The Telegraph that was just published

This is part of our universe.
An area of sky about the size of a grain of sand held at arm's length.
The spiked features are stars in the Milky Way.

Why are planetary scientists, astrobiologists and and SETI scientists so negative (pissed off, even) about Avi Loeb’s repeated claims that 3I/Atlas may be an invading alien spaceship?

The driving motivation behind science is to ultimately answer one simple question (with no simple answer): are we alone in the universe?
