3I/ATLAS is a rare, comet-like interstellar object that formed around a distant star and traveled for millions of years before entering our solar system. It is only the third such object ever detected by astronomers.

I hugely messed up trying to change the timing of the poll and so I deleted all replies 😩
https://mastodon.social/@franco_vazza/117217928343077828Anyway, roughly 50% of the 38 respondents correctly choose "no, never", while the rest was scattered in the other two options.
So let me briefly explain:
-
This Earth science perspective captures the interplay between Rayleigh scattering and atmospheric refraction during a coastal twilight in Sardinia. As the sun descends, shorter wavelengths of light are dispersed, leaving the vibrant long-wave reds and oranges that define the golden hour. This phenomenon is intensified by the density of the lower atmosphere near the horizon, which bends light paths and creates the distinctive visual compression of the solar disk. Such observations are critical for studying atmospheric composition and the optical mechanics that influence global climate modeling.

Barnard 228, also known as the Dark Wolf Nebula, is a dense molecular cloud located in the constellation Lupus. Situated approximately 500 light-years away, this dark nebula consists of cosmic dust and gas that obscure background visible light through extinction. Such interstellar clouds serve as critical sites for star formation, where gravitational collapse eventually triggers the birth of new stellar systems within the Milky Way. Observing these cold, opaque regions allows astronomers to study the early stages of the stellar life cycle and the chemical composition of the interstellar medium.

Neptune Clouds on the Dark Spot
This photo was taken by NASA Voyager 2 wide-angle camera. Light at methane wavelengths is mostly absorbed in the deeper atmosphere. The bright, white feature is a high-altitude cloud just south of the Great Dark Spot.

How to Unteach Relativity
------------------------You may know I found the Unified Field Theory: https://github.com/chemoelectric/iris-numbers-and-unified-field-theory
So Relativity needs unteaching. Do it thus:
Einstein treated c as ‘the speed of light in a vacuum’.
But c is ‘the speed of waves in an electromagnetic field’.
Putting the two definitions side by side makes Einstein’s error obvious: an EM field is not a vacuum! It is, in fact, the medium for EM waves the ether had been presumed to be...

Spiral Galaxy NGC 6744 serves as a premier archetype of a grand design spiral system, located approximately 30 million light-years away in the southern constellation Pavo. Spanning nearly 175,000 light-years, its diameter exceeds that of our own Milky Way. High-resolution imaging reveals a prominent elongated core surrounded by expansive spiral arms defined by pinkish star-forming regions and obscuring cosmic dust lanes. Observation of such systems provides critical data regarding galactic evolution and the structural dynamics of large-scale stellar populations in our local universe.

Conjoined Moons
Looking like half of a figure eight, two of Saturn moons appear conjoined in this image from NASA Cassini spacecraft. The moon Dione, at the top in the image, is actually closer to the spacecraft, appearing to blend seamlessly with the moon Rhea.

This false-color infrared imaging captured by the Cassini spacecraft reveals the intricate fluid dynamics of Saturns upper atmosphere. By utilizing infrared wavelengths, astronomers can penetrate the planets thick haze to visualize localized thermal emissions and deep-seated storm activity. These observations are critical for mapping heat distribution and atmospheric composition across the gas giant. Discovery and analysis of these thermal patterns provide essential data on the internal energy mechanisms that drive Saturns complex weather systems.

The European Space Agency's Planck mission has produced the most detailed map of the Cosmic Microwave Background to date, offering a comprehensive look at the ancient light emitted shortly after the Big Bang. This high-resolution survey identifies subtle temperature fluctuations that represent the seeds of today's galaxies. By measuring these cosmic relics, researchers can more accurately calculate the age, expansion rate, and overall composition of our universe, confirming the foundations of the Big Bang inflationary model. Explore the earliest light in cosmic history through this definitive map of the early universe.

Ganymede At 150,000 Miles
This picture of Ganymede, Jupiter's largest satellite, was taken by NASA's Voyager 1 on the afternoon of March 5, 1979, from a range of about 250,000 km (150,000 mi.). The center of the picture is at 60 north latitude and 318 longitude, and the distance across the bottom of the photograph is about 1000 km (600 mi.). The smallest features visi...

Continuous scanning through the layers of the dark matter distribution in a simulated 150^3 Megaparsec volume, of the "baseline" (=simple physics) run of our Makitra https://cosmosimfrazza.eu/makitra suite of simulations. The resolution is small (512^3 particles/cells) and yet the intricacy of the web of matter is gorgeous already.
