Astronomers Discover a Giant Object in the Cygnus Constellation
In the past three decades, almost 4,000 planet-like objects have been discovered orbiting isolated stars outside the Solar System (exoplanets). Beginning in 2011, it was…
Scientists Simulate Alien Atmospheres on Earth
Researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, are cooking up an alien atmosphere right here on Earth. In a new study, JPL scientists…
K Stars May Be Perfect for Finding Habitable Worlds
