Are there planets beyond Earth where humans can live? The answer is maybe, according to physicists examining F-type star systems.
Are there planets beyond Earth where humans can live? The answer is maybe, according to a new study from University of Texas at Arlington physicists examining F-type star systems.
"F-type stars are usually considered the high-luminosity end of stars with a serious prospect for allowing an environment for planets favorable for life," Dr. Cuntz said."However, those stars are often ignored by the scientific community. Although F-type stars have a shorter lifetime than our sun, they have a wider HZ. In short, F-type stars are not hopeless in the context of astrobiology.
In one case, the planet HD 111998, also known as 38 Virginis, is always situated in the HZ. It is located 108 light-years from Earth and is thus considered to be part of the extended Solar System neighborhood. It's also 18% more massive and has a radius 45% greater than the sun, Cuntz said. Among possible future projects, the team noted, are studies of planetary orbits, including cases of part-time HZ planets; explorations of the relationships between planetary habitability and stellar evolution, including astrobiological aspects; and assessments of exomoons for distinct systems.

Snowball Earth: Researchers discover unique Scottish rocks record when Earth was first encased in iceMore than 700 million years ago, the Earth was plunged into a state that geologists call 'snowball Earth', when our planet was entirely encased in ice. This happened when the polar ice caps expanded so far that they joined up around the equator.

Physicists capture images of atoms flowing along a boundary without resistance despite obstacles in their pathTypically, electrons are free agents that can move through most metals in any direction. When they encounter an obstacle, the charged particles experience friction and scatter randomly like colliding billiard balls.
