Time travels faster on Mars than on Earth, and here's why

Recent observations indicate that a weak spot in Earth's magnetic field is expanding, but scientists assure that this phenomenon does not pose a threat to life on the planet. The magnetosphere, which has undergone significant changes throughout Earth's history, continues to protect the planet from harmful space weather.

A massive sunspot complex, identified as AR 4294-4296, has emerged on the sun and is currently facing Earth. This sunspot is comparable to the one that caused the Carrington Event in 1859, although it remains inactive at this time.

A recent observation from a Mars orbiter has revealed a striking impact crater on the Red Planet, characterized by debris that resembles butterfly wings unfurling across the Martian surface. This captivating image highlights the dynamic geological processes at play on Mars, showcasing the planet's unique landscape.

A striking image captured in the Saharan Desert has raised questions about whether it is a crater. The photo, featured as Space.com's photo of the day on December 5, 2025, showcases a unique geological formation that resembles a bull's-eye.

December's 'Cold Moon' rose on December 4, 2025, marking the final full moon of the year as it approached its closest point to Earth in its monthly orbit. This celestial event, known for its striking appearance, captivated stargazers around the world.

A new cosmic map has reignited the debate surrounding the 'Hubble tension,' a discrepancy in the measurement of the universe's expansion rate. This development suggests that previous assumptions may need reevaluation, as researchers work to narrow down viable explanations for the observed inconsistencies.

The Geminid meteor shower has commenced, with its peak expected on the nights of December 13 and 14, 2025, offering a spectacular display of up to 150 shooting stars per hour in a moonless sky. This annual event is renowned for its vibrant and colorful meteors, captivating stargazers around the world.

In November, a rare solar super-flare resulted in a significant spike in cosmic radiation levels in Earth's atmosphere, reaching the highest levels recorded in nearly 20 years. This event underscores the dynamic nature of solar activity and its direct impact on our planet's environment.
