Four new "hot Jupiter" extrasolar planets have been detected as part of the Hungarian-made Automated Telescope Network-South (HATSouth) exoplanet survey. The newly found alien worlds are generally similar in size, but vary ...
A team of researchers from Arizona State University and Vanderbilt University has found evidence that suggests the exoplanets surrounding the star Trappist-1 may be too wet to support life. In their paper published in the ...
Using NASA's prolonged Kepler mission, known as K2, astronomers have identified two new gas giant exoplanets. The newly found alien worlds, designated HD 89345 b and HD 286123 b, are warm, low-density sub-Jovian planets circling ...
