Astronomers have flagged a distant world, Kepler-442 b, as potentially more hospitable than our own planet — at least according to a new habitability rating system. Discovered by the Kepler Space Telescope, this rocky exoplanet lies some 1,200 light-years away and orbits within the habitable zone of its star. By one index, it earns a… Read More: Exoplanet Kepler‑442 b edges past Earth in new habitability index —… »

Humanity’s dream of living on Mars may still be within reach — but the clock is ticking. According to a recent study published in the journal Space Weather, prospective astronauts visiting the Red Planet should limit their total mission duration to about four years. Beyond that, accumulated exposure to cosmic and solar radiation could become a… Read More: New Study: Humans Can Safely Stay on Mars for Up… »

A fascinating scientific discovery is shedding new light on how cosmic events may have influenced Earth’s environment millions of years ago. A team of international researchers, led by Dr. Dominik Koll, has uncovered evidence of a mysterious radioactive isotope spike deep within the Pacific Ocean — one that could trace back to a nearby supernova… Read More: Deep-Sea Clues Reveal Possible Ancient Supernova That Shaped Earth 10… »

For decades, astronomers have looked at the night sky and seen one familiar companion — our Moon. But it turns out Earth hasn’t been traveling alone after all. NASA-supported observations have confirmed the discovery of a tiny asteroid called 2025 PN7, a “quasi-moon” that’s been quietly accompanying our planet for more than half a century.… Read More: Earth Just Got a Second Moon — Kind Of: Meet… »

Astronomers have uncovered a distant and icy world on the far edge of our Solar System — a frozen body so remote it takes roughly 25,000 years to complete just one orbit around the Sun. The discovery of 2017 OF201 is already reshaping how scientists see the Solar System’s outer frontier and challenging ideas about… Read More: Astronomers Discover a Distant “New World” Orbiting the Sun Every… »
