Scientists have redefined the conditions which could make an exoplanet potentially habitable, narrowing down the number of worlds that could become targets in the search for life beyond Earth.For a study published in The Astrophysical Journal, a team of researchers used 3D climate models incorporating atmospheric chemistry to examine the
Earth's pleasant, life-giving atmosphere is turning out to be somewhat of an oddity. With almost 4,000 planets so far discovered orbiting stars beyond our solar system, scientists are finding that atmospheres come in a wide range of recipes. To get a better understanding of that cosmic chemistry, a team at
The first known interstellar visitor to the solar system is keeping astronomers guessing.Ever since it was spotted in October 2017, major mysteries have dogged the object, known as ‘Oumuamua (SN Online: 10/27/17). Astronomers don’t know where it came from in the galaxy. And they’ve disagreed over whether ‘Oumuamua is an
Astronomers have discovered a population of incredibly fast-moving stars bearing down on the Milky Way. It is possible that these newly found "hypervelocity" stellar bodies were created in another galaxy, before being hurled out into intergalactic space on a collision course with the Milky Way.Our galaxy is populated by over
It's beginning to look like life here began out there. The number of potentially habitable worlds has exploded. Organic molecules are being found in comets and cosmic clouds. So is there an interstellar conveyor belt seeding life throughout the galaxy?Monash University’s Professor John Lattanzio has told the annual meeting of the Astronomical
(Inside Science) – When it comes to looking for alien life, scientists mostly focus on where there is water. Now researchers suggest that looking at "bioessential" elements such as phosphorus and molybdenum could help judge a world's potential for life.There is life virtually wherever there is water on Earth, from
Astronomers have found an abundance of exoplanets, but no exomoons. Despite ongoing efforts, the tiny celestial bodies have just been too elusive to detect using modern technology. However, researchers might have just hit paydirt. They've used Kepler Space Telescope data to discover signs of what looks like a Neptune-sized moon
Dr. Norman Bergrun, a former NASA Engineer, has claimed "giant" alien spacecraft are to be found in Earth's solar system around ringed planets such as Jupiter, Saturn and Uranus – not the first time the alien enthusiast has made such fantastical claims. UFO hunter Dr. Bergrun claimed the ships are "sucking"
