SALON - In distant galaxies exist stars that are smaller and cooler than our own Sun. These so-called red dwarf or M dwarf stars also live 10 times as long as stars like ours and are the most numerous in our galaxy, outnumbering stars like ours 10 to 1. Because of their longevity and quantity...
CNN - Astronomers have spied an intriguing phenomenon in the distant universe — a galaxy that closely resembles the Milky Way — and it’s challenging key theories on how galaxies evolve. The faraway system, called ceers-2112, was spotted by an international team using the James Webb Space Telescope. Like our home galaxy, the newly discovered...
STUDY FINDS - Could Earth have a twin in a distant galaxy that looks just like ours? Scientists have made an astronomical discovery that disputes previous theories of galaxy formation. An international team of astronomers used NASA’s James Webb Space Telescope to identify the most distant barred spiral galaxy similar to our Milky Way ever...
NEWSWEEK - While Jupiter may be our planetary guardian angel, protecting us from harm, gas giants in other solar systems might actually wreak havoc on other exoplanets nearby. In our solar system, Jupiter's huge gravitational field deflects comets and asteroids away from our delicate, rocky home planet. According to a new study in The Astronomical...
CNET - "We found that the Galilean moons of Jupiter, one of which is the largest moon in our solar system, would very quickly destroy any large rings that might form," Stephen Kane, an astrophysicist from the University of California, Riverside, who led the research, said in a statement. "As a result, it is unlikely...
ASTRONOMY ONLINE - Astronomers know that most galaxies house supermassive black holes in their centers, from the largest galaxies down to small dwarfs. They also know that when supermassive black holes are actively feeding, they can slow or even stop the formation of stars in their home. Although this relationship has been well established for...
