“This kind of radio signal just wouldn’t exist unless material had completely left the star’s bubble of powerful magnetism,” ...

Add Yahoo as a preferred source to see more of our stories on Google. Red dwarfs dominate the neighborhood and often host rocky worlds in temperate orbits. Yet their environments may hinder complex ...

This artist’s impression shows a sunset seen from the super-Earth Gliese 667 Cc. Astronomers have estimated that there are tens of billions of such rocky worlds orbiting faint red dwarf stars in the ...

Astronomers have discovered an Earth-size planet orbiting an ultracool red dwarf star similar in size to Jupiter. The red dwarf, located some 55 light-years away, is 100 times less bright than the sun ...

The Copernican Principle, named in honor of Nicolaus Copernicus (who proposed the heliocentric model of the universe), states that Earth and humans do not occupy a special or privileged place in the ...

In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy. Earth-like ...

Small red stars make up three out of every four stars in the galaxy, and many host planets. Credit: Johns Hopkins APL illustration Perhaps surprisingly, the majority of stars in the galaxy are not sun ...

What can planets orbiting red dwarf stars teach scientists about planetary formation and evolution? This is what a recently submitted study hopes to address as an international team of researchers ...

As of 2025, astronomers have identified at least 14 stars within 10 light-years of the Sun. After the Alpha Centauri system, the next closest is Barnard’s Star, a solo red dwarf roughly 6 light-years ...

How did this red dwarf star 240 light-years away end up with a gas giant planet? Credit: University of Warwick / Mark Garlick illustration Astronomers have discovered a world outside the solar system ...

Scientists have spotted another road bump in the quest to locate extraterrestrial life. Red dwarf stars, thought to make up most of the stars in the Milky Way, spew out so much UV radiation that they ...

For all the talk about life across the cosmos, Earth remains the only confirmed example. That single data point makes your place in the universe feel both ordinary and strange. Two facts sharpen the ...
