Exploring Galactic Mysteries: A comparison between traditional dark matter models and a new theory involving scale-dependent gravity, suggesting that gravity's strength varies over large distances to explain galactic rotation without unseen particles.

Is Dark Matter real, or is our understanding of gravity wrong?

Is Dark Matter real, or is our understanding of gravity wrong? A new study suggests gravity itself might change shape at cosmic distances. For decades, astronomers have observed that galaxies spin too fast. According to Newton's laws, stars on the edges should fly off into space, yet they hold together. To explain this, physics postulated Dark Matter—invisible mass holding galaxies together. For decades, astronomers have observed that galaxies spin too fast. According to Ne

New radio data from the Juno spacecraft has just rewritten the textbooks.

For 50 years, we thought we knew Jupiter's size. New radio data from the Juno spacecraft has just rewritten the textbooks. Since the Voyager missions of the 1970s, our understanding of Jupiter's shape has been based on just six measurements. Now, researchers at the Weizmann Institute of Science have used 26 new measurements from NASA's Juno spacecraft to create the most precise model of the gas giant ever made.

The Perchlorate Paradox: Exploring how toxic Martian soil could be transformed into stronger habitats through bacteria-induced "space bricks," leveraging perchlorate's surprising strengthening effect to build infrastructure on Mars.

Toxic soil on Mars was supposed to kill our building bacteria

Toxic soil on Mars was supposed to kill our building bacteria. Instead, it made them build stronger. Mars is covered in Perchlorate, a toxic salt that poses a major challenge for future colonizers. Scientists at the Indian Institute of Science (IISc) feared this chemical would kill the bacteria needed to manufacture "biocement" bricks from Martian soil.

The Fermi Paradox and the Search for Cosmic Intelligence

This is the heart of the Fermi Paradox, a term for the profound conflict between the sheer statistical probability that we should be surrounded by evidence of intelligent life and the observed reality of a silent, seemingly empty cosmos. For decades, our telescopes and radio receivers have heard nothing but silence.

M dwarf stars (Red Dwarfs)

When you look up at the night sky, the stars that catch your eye are often giants—luminous, massive beacons similar to, or much larger than, our own Sun. It’s natural to think of these bright points of light as typical. But this perception is a profound illusion.

What New Scar on the Moon Teaches Us?

Despite eons of gazing at the "Man in the Moon," many of us miss the fact that our celestial neighbor is still under construction. While the massive, basin-forming impacts ended billions of years ago, the Moon is still struck by asteroids and comets today. Catching these impacts is a challenge, but thanks to the Lunar Reconnaissance Orbiter Camera (LROC), we can now spot fresh craters that appeared almost overnight.
