Who and When invented that Sun is the center of the solar system?🌕
It was in 1543, when the Polish astronomer Nicolaus Copernicus (1473-1543) expressed the idea of heliocentricity.
He claimed that the center of the Solar System is not the Earth at all, but the Sun.
After 70 years, Galileo Galileo (1564-1642), using a new invention a telescope to observe the sky, he saw a family of four satellites orbiting Jupiter.
This is the first evidence that not everything moves around the Earth.

Axiom Space Lunar Suit Delays Threaten Moon Landing
Axiom Space, the private contractor building new spacesuits for NASA, is missing critical deadlines, putting the 2028 crewed Moon landing at risk. 🧑🚀
The company is collaborating with fashion house Prada on the design, yet struggles with basic financial and organizational stability.

How much water is there on Earth?💧
About 70 percent of the surface of our planet is covered with water.
However, compared to the radius of the Earth, the depth of the oceans is small.
If all the water from the earth's surface were collected into a ball, then its radius would be only about 700 kilometers.

Galaxies disappear forever
Our Universe is expanding with increasing acceleration, irreversibly hiding trillions of star systems from us. The light of distant galaxies physically cannot overcome the growing distance to Earth. Billions of years from now, the night sky will become completely empty for Earth observers.

What types of galaxies exist?
Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.
Elliptical galaxies have smaller portions of gas and dust, contain older stars, and don't form many new stars.
The largest and rarest of these galaxies – known as giant ellipticals – are about 300,000 light-years across.

University of Arkansas students 3D-print moon bricks
On Nov 10, Cole McCallum and Wan Shou at the University of Arkansas made 3D-printed blocks from artificial moon dust.
These LEGO-like prototypes use laser powder bed fusion and require no binding agents.

The age of chemical poverty
The first half-billion years after the Big Bang were a time of extreme chemical simplicity. The universe was a featureless mixture of hydrogen and helium—no metals, no dust, no complex molecules to be found anywhere.
This era of "chemical darkness" only ended with the birth of the first stars, which acted as the universe's initial manufacturing plants. Before that, the cosmos was sterile; the total lack of carbon and oxygen meant that complex structure formation was physically impossible. We exist in the universe's golden age of chemical abundance.

Extreme conditions deep inside Uranus and Neptune create high electrical conductivity and a powerful dynamo effect that explain the strange lopsided magnetic fields of the planets 🪐. This solves a 40-year-old mystery about the magnetic orientation of these ice giants.

What are the Quasars?🧐
Quasar is an astronomical object of very high luminosity found in the centres of some galaxies and powered by gas spiraling at high velocity into an extremely large black hole.🕳 And the nearest quasar is only 13.03 billion light years, so we don't need to be nervous, but the chance is never 0%.😉
