James Webb telescope took its first direct exoplanet image.

JWST telescope took the first image of an exoplanet. That exoplanet is HIP 65426 b, the gas giant 348 light years from Earth and located in the constellation Centaurus. 

The HIP 65426 b is carbon-poor. But an oxygen-rich version of "our" gas giants. The exoplanets are named similarly to their binary star. But there is a letter b or c, etc. behind that name. 

The binary star HIP 65426 is spectral type A2V and its color is blue. The surface temperature of that star is about 7500-10 000 kelvin. The surface temperature of the sun is about 5778 K. The HIP 65426 burns its fuel very fast. And this means the lifetime of HIP 65426 is not so long, that there can form some kind of intelligent and technically advanced civilization. But the HIP 65426 b is otherwise a very interesting object. 

Maybe later we will get better images of the Proxima Centauri b. And there is the possibility that the JWST can find some kind of alien life from some planets. The HIP 65426 b is a harder target than Proxima b. Its binary star is much brighter. And the distance to that star is much longer than to Proxima b, which is about 4 light-years from Earth. 

Maybe JWST finds more exoplanets and uncovers their moons. And there is the possibility that JWST will solve the mystery of the existence of Gliese 581 g and d in that multiplanet solar system that orbits the M3-class red dwarf 20 light years from Earth in the Libra constellation.

Schrödinger's cat: and the limits of that idea.

"In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition". (Wikipedia, Schrödinger's cat). But the same thing can use as model for many other thought experiments.  Sooner or later, or at least in the ultimate end of the universe, the Schrödinger's cat will turn into wave movement. The information that this cat involved exists but the cat does not exist in its material form. The information doesn't ever vanish. It just turns its shape.  We are all trapped in the universe and time. The universe is the space that is entirety to us. There are no confirmed other universities. But the multiverse is a logical continuum for the expanding galactic megastructures.  The problem with natural things is this. They are black and white. They exist or do not exist. Could there be something, that exists and not exists at the same time?  Scrödinger's cat is thinking experiment about case their cat is not dead or not alive. But in this...

The string theory offers a new way to calculate Pi.

"Scientists discovered a new series for pi through string theory research, echoing a 15th-century formula by Madhava. By combining Euler-Beta Functions and Feynman Diagrams, they modeled particle interactions efficiently. Credit: SciTechDaily.com" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Leap in Mathematics) People normally think that. The pi is the ratio of the circumference circle's circumference to the circle's diameter. The Pi is a mathematical constant 3.14159..., the endless decimal number. The Pi is interesting because developers can use that decimal number to make the encryption algorithms stronger.  The idea is that the encryptions program hides the message's original ASCII numbers by multiplicating those numbers with some decimal number. Or the system can add some numbers to those ASCII numbers.  "Aninda Sinha (left) and Arnab Saha (right). Credit: Manu Y" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Le...

There are always more than three actors in the real world.

"An international research team is advancing precision timekeeping by developing a nuclear clock using thorium isotopes and innovative laser methods, potentially transforming our understanding of physical constants and dark matter. (Artist’s concept.) Credit: SciTechDaily.com" (ScitechDaily, Unveiling the Thorium Nuclear Clock and Its Time-Twisting Secrets) From Three-body problem... There are no pure three-body systems in nature. There are always more than three components in the system. For making real three-body systems we must separate those three bodies from the environment. Otherwise, there are stable effects. But nobody can predict some effects like distant supernova explosions or sun eruptions.  And one of those things that affect all bodies is time. When radioactive materials decay. That affects the stability and symmetry of the object.  Energy levels affect the existence of things like neutrons. The thorium atom clocks are next-generation tools for time measurement....
