Searching for Habitable Super-Earth Exoplanets Around Nearby M-dwarfs
Detection and characterization of potentially habitable Earth-size extrasolar planets is one of the major goals of contemporary astronomy. By applying the transit method to very low-mass M-dwarfs, it is possible […]

Some Sun-like Stars are Earth-eaters
Some Sun-like stars are ‘Earth-eaters.’ During their development they ingest large amounts of the rocky material from which ‘terrestrial’ planets like Earth, Mars and Venus are made. Image: What if […]

Don't Forget F-type Stars in Search for Life
Scientists searching for habitable planets beyond Earth shouldn’t overlook F-type stars in favor of their more abundant, smaller and cooler cousins, according to new research from University of Texas at […]
