The Sweden Solar System is the largest scale model of the Solar System in existence, and it spans the entire Swedish territory. It was created by astronomers Nils Brenning and Gösta Gahm to help visualize and understand the immense scale of our planetary system. The scale of the Sweden Solar System is 1:20 million. This […]

Twice a Day, Earth’s Surface Rises and Falls: A Lab Detects the Subtle Sway of the Planet
Twice a day, Earth’s surface experiences a slight rise and fall—a phenomenon almost imperceptible to human senses, yet one that reveals a constant dance between our planet, the Moon, and the Sun. This oscillation, known as Earth tide or solid Earth tide, is a direct consequence of the same gravitational forces that cause ocean tides, […]

Scientists Explain What Happened 14 Million Years Ago When the Solar System Passed Through the Orion Star-Forming Region
An international team of researchers, led by the University of Vienna, has revealed that the Solar System passed through the complex Orion star-forming region, a structure linked to the so-called Radcliffe Wave, approximately 14 million years ago. This interstellar journey may have reduced the size of the heliosphere—the protective bubble surrounding our planetary system—allowing greater […]

The Moon Is Much Older Than We Thought, and Its Crust Has Melted Several Times
The Moon, our natural satellite, has witnessed impressive geological events since its formation. According to a recent study published in the journal Nature by an international team of researchers from the University of California, Santa Cruz, the Max Planck Institute for Solar System Research, and the Collège de France, the Moon experienced volcanic activity so […]

The Sun Took Between 10 and 20 Million Years to Form from Elements Produced in Ancient Red Giants
An international team of scientists has made a major breakthrough in understanding how and when the Sun formed about 4.6 billion years ago. This research, conducted at the GSI/FAIR center in Germany, provides new insights into the star formation process and helps us better understand the origins of our solar system. The findings have been […]

A star passed so close to the Solar System billions of years ago that it originated the moons of the outer planets
Billions of years ago, a star may have passed incredibly close to our Solar System, triggering a series of cosmic events that led to the creation of the moons around the outer planets and the unusual orbits of distant celestial bodies. This new theory, backed by over 3,000 computer simulations, was proposed by a team […]

The asteroid that wiped out the dinosaurs came from somewhere between Jupiter and Saturn
A recent study led by scientists from the University of Cologne has provided insights into the origins of the asteroid that caused the extinction of the dinosaurs about 66 million years ago. The research, published in the journal Science, reveals that this catastrophic asteroid likely originated from a region of space beyond Jupiter, in the […]

Not a drop of water on the surface of Mars, but there are oceans inside that could harbor life
Mars, often called the Red Planet, has long fascinated scientists and the public alike with the tantalizing possibility of water—and potentially life—beneath its desolate surface. Recent research offers a breakthrough in this quest, revealing that while there may not be any liquid water on the Martian surface, a vast underground reservoir could rival Earth’s oceans. […]

Scientists Discover Accessible Tunnel Beneath the Moon’s Surface
An international team of researchers led by the University of Trento has made a landmark discovery. For the first time, they have confirmed the existence of a tunnel beneath the lunar surface, potentially a hollowed-out lava tube. The study has been published in the esteemed scientific journal Nature Astronomy. These structures had been hypothesized for […]
