Solar System’s Journey Through Orion Complex May Have Altered Earth’s Climate

The movement of the solar system through the Orion star-forming complex around 14 million years ago may have influenced Earth’s climate, according to scientists. This dense region of space, part of the Radcliffe Wave galactic structure, could have compressed the heliosphere—the protective shield surrounding the solar system—while increasing interstellar dust reaching Earth. Researchers suggest that … Read more

Strange Fast Radio Bursts Emerge from an Ancient Dead Galaxy, Baffling Scientists

A distant galaxy that ceased star formation billions of years ago has been found emitting unusual radio signals, a phenomenon that has left astronomers searching for answers. Observations have revealed fast radio bursts (FRBs) originating from the outskirts of this long-dead galaxy, challenging current understanding of how these cosmic events occur. Typically associated with young, … Read more

Gravitational Waves Reveal Black Hole Ancestry Through Spin Analysis

Ripples in spacetime, known as gravitational waves, are being used to determine the ancestry of black holes. These waves, first theorised by Albert Einstein, are offering insights into how black holes form and evolve. Scientists have uncovered that the spin of a black hole can indicate whether it originated from repeated mergers in densely packed … Read more
